    Implementing Security, Part II: Hardening Your UNIX/Linux Servers | killexams.com real questions and Pass4sure dumps

    Continuing with part 2 of this two-article series, Joseph Dries helps you continue to expand upon your list of basic security processes by looking at UNIX/Linux hardening, protecting your servers from network based TCP/IP attacks, and utilizing centralized logging servers.

    This article was excerpted from The Concise Guide to Enterprise Internetworking and Security.

    "A commercial, and in some respects a social, doubt has been started within the last year or two, whether or not it is right to discuss so openly the security or insecurity of locks. Many well-meaning persons suppose that the discussion respecting the means for baffling the supposed safety of locks offers a premium for dishonesty, by showing others how to be dishonest. This is a fallacy. Rogues are very keen in their profession, and already know much more than we can teach them respecting their several kinds of roguery. Rogues knew a good deal about lockpicking long before locksmiths discussed it among themselves, as they have lately done. If a lock—let it have been made in whatever country, or by whatever maker—is not so inviolable as it has hitherto been deemed to be, surely it is in the interest of honest persons to know this fact because the dishonest are tolerably certain to be the first to apply the knowledge practically; and the spread of knowledge is necessary to give fair play to those who might suffer by ignorance. It cannot be too earnestly urged, that an acquaintance with real facts will, in the end, be better for all parties." —Charles Tomlinson's "Rudimentary Treatise on the Construction of Locks," published around 1850

    It has been said that the wonderful thing about standards is there are so many to choose from. The same choice is available in the UNIX arena. There are two basic flavors, BSD-derived and AT&T System V-derived. BSD-derived UNIX systems include OpenBSD, FreeBSD, NetBSD, BSDi, MacOS X, and SunOS 4. System V-derived UNIX systems include HP-UX and Solaris (SunOS 5). Other UNIX systems, such as AIX, provide commands that will act BSD-ish or System V-ish, depending on how they were invoked. Linux is not derived from any UNIX, but depending on the distribution, borrows from both BSD and System V semantics. Actually, Linux itself is just the operating system kernel and supporting drivers. Most Linux distributions use the GNU system (http://www.gnu.org), thus they are called GNU/Linux distributions. There are hundreds of available GNU/Linux distributions, but even the "top 5" are different in their default commands, startup scripts, filesystem layout, included utilities, and packaging systems.

    What does this mean to you? Unlike Windows NT, including Windows 2000, it is a far more complex process to describe how to harden a UNIX/Linux server. This next section provides some common procedures that can be applied across UNIX versions and GNU/Linux distributions. Following that are some pointers to living documents on the Internet, which track available data and releases, and go into a more detailed account of how to harden a server for a particular task.

    Common Steps for Hardening UNIX/Linux Servers

    The process of building a UNIX or GNU/Linux server for use as a firewall or DMZ server begins with installation. Eliminating points of attack, such as filling the filesystem, or removing unnecessary libraries and services, is equivalent to removing possible entry points for intruders.

    Some common guidelines for configuring UNIX servers with a more secure default stance are available from CERT's Web site at ftp://info.cert.org/pub/tech_tips/UNIX_configuration_guidelines.

    Partition for Protection

    Besides having separate partitions for the obvious, such as SWAP and /tmp, you should protect against out-of-disk-space denial-of-service attacks. Intruders might try to create excessive generation of logging data or fill your file system with large files through FTP or mail spool. The best way to protect against this is to segment the filesystem hierarchy into separate physical partitions.

    The root partition / can be small because it generally contains just the kernel—the necessary files, libraries, and configuration for booting in /bin, /sbin, /etc, and /lib. Access to the attached devices is provided through the /dev and /devices directories. Many GNU/Linux distributions store kernels and symbol data in the /boot directory, whereas kernel libraries are stored under /lib.

    The /usr partition is normally where user-accessible applications are stored. Normally, /usr does not contain data or configuration files that change; therefore, an added security measure can be mounted as read-only.

    The /var partition stores system logs and data services such as mail, Web, databases, printing, running services, package management, and so on. On a mail server, you might want to make /var/spool/mail, or /var/mail in Solaris, a separate partition, or—even better—a separate disk array. If you only create one separate partition from /, /var is the one you should separate.

    The /usr/local directory structure, and in Solaris the /opt directory, often contains locally installed optional software, configuration files, and data. /usr/local is normally not affected by operating system upgrades. Depending on how you use those directories, they too can be mounted as read-only.

    These are suggestions and guidelines only, and are different from recommended settings for a system that contains user accounts, usually in /home.

    Disable Extraneous inetd Services

    inetd is the UNIX "Internet Super Server." It is a daemon process that is invoked at boot time and reads in a flat file configuration database normally found at /etc/inetd.conf. inetd listens for incoming connections on the defined IP ports. When a connection is initiated on a defined port, it invokes the configured program to service the request. After the connection is finished, the process invoked to service that request terminates. This was originally designed to lighten the load and resources required for systems.

    There are a number of services enabled through inetd, and almost all of them should be disabled for building firewalls and DMZ servers. Besides normally disabling FTP, TFTP, Telnet, and the Berkeley r* commands, disable the following:

  • in.named—BIND name services daemon. Except for your DNS servers, you should not be running DNS on your firewall or DMZ servers.

  • in.fingerd—Finger daemon that can be used to show user information and lists of users who are logged in. There is no reason to advertise that information to would-be intruders.

  • daytime—Connections to this service display the date and time on the system in a string format. Getting the date and time of a system is useful for an intruder trying to implement replay attacks.

  • time—Connections to this service return the time as a 32-bit value representing the number of seconds since midnight 1-Jan-1900. Do not provide intruders with your exact system time.

  • echo—This is a diagnostic service that echoes incoming data back to the connecting machine.

  • discard—This is a diagnostic service that does not echo (thus discarding) the incoming data stream back to the connecting machine.

  • chargen—This is a diagnostic service that automatically generates a stream of characters sent to the connecting machine.

  • systat—Connections to this service provide a list of all processes and their status.

  • netstat—Connections to this service provide a list of current network connections and their status.

  • Install and Configure tcp_wrappers

    Install and configure Wietse Venema's tcp_wrappers on both your firewall and DMZ servers. tcp_wrappers allows you to define access control to various services, depending on a limited set of criteria, such as username, IP address, or DNS domain.

    You might be asking why it's necessary to configure and install additional products when your firewall will be doing the same thing. And that's a valid question. The answer is to avoid single points of failure, and to provide security in layers. If one layer is pierced and bypassed, other layers will be standing guard behind the breach.

    tcp_wrappers are lightweight and extremely useful on internal servers; not just on firewalls and DMZ servers. Keep in mind that most information security breaches, intentional or accidental, happen internally. It's only the external defacements, massive distributed denial of service (DDoS) attacks, virus-du-jour, and stolen credit card databases that grab the press. That, and misplaced hard drives with highly sensitive nuclear information.

    tcp_wrappers have two main files that allow access to the individually defined services. The following two files are checked for rules governing access to individual or wildcard services:

    /etc/hosts.allow /etc/hosts.deny

    Like most firewalls, access is granted or denied on the first matching rule. The rules are checked in order, first in hosts.allow and then in hosts.deny.

    Care should be taken when using the KNOWN or UNKNOWN wildcards. ALL will always match whatever criteria you are testing. Read the hosts_access manual page included with tcp_wrappers for further details on syntax and rules setup.

    tcp_wrappers is installed and configured by default on most GNU/Linux distributions and BSD releases. For those UNIX systems that do not have tcp_wrappers installed by default, they can be found at ftp://ftp.porcupine.org/pub/security/index.html. Retrieve the source, compile, and install the binaries on the servers.

    Lock Down Your DNS Server

    The Berkeley Internet Name Daemon, or BIND, is the reference implementation of the name service providing DNS for the Internet. The Internet Software Consortium (ISC) is responsible for implementing and maintaining BIND. There are three basic versions of BIND: BIND 4, BIND 8, and (recently) BIND 9.

    BIND 4 has been around forever, and has its share of exploits. Only very old versions of UNIX systems and GNU/Linux distributions came with BIND 4. Still, you'll be surprised how many installations still have the older BIND 4 running. You should upgrade to a newer version of BIND. The unfortunate thing is that the file format defining the zones served by the server has changed. There are conversion scripts, but there is sure to be some hand editing.

    BIND 8 is the current stable release, and offers many more features and better control and granularity in access control. The settings described later are discussed with BIND 8 in mind.

    BIND 9 was released late in 2000. It offers many new features, such as IPv6 support, DNSSEC, full Dynamic DNS, incremental zone transfers, multiple views (internal, external, and so on) from a single server, and scalability improvements. If any of those features are important to your configuration, you should investigate using BIND 9; otherwise, it's best left to the adventurous.

    Although almost all UNIX systems and GNU/Linux distributions come with BIND as the name server, it is important you make sure you are at a recommended release. Before deploying a DNS server, internally or on the DMZ, make sure it is at least version 8.2.2-P5. Any version prior to that has serious exploits. This warning should not be ignored. The Internet Software Consortium themselves have issued a statement that if you are running any version of BIND prior to 8.2.2-P5, you should assume your server has already been compromised. Check your UNIX system or GNU/Linux distribution. If the version of BIND is not at least 8.2.2-P5, check with your vendor for upgrades. If an upgrade is not available, you can compile a version of BIND yourself on a workstation, and install the binaries on your server. The source code can be found at http://www.isc.org/products/BIND/.

    First, restrict zone transfers to specific secondary servers in your primary zones. The acl command allows you to define an access control list composed of blocks of addresses to be used with a named identifier. Using ACLs provides a self-documenting method of administrating the named.conf configuration file. In the following example, we define two ACLs comprising our externally visible DNS servers and the secondary servers at our ISP:

    acl your-company-dns { 172.16.30.12; 172.16.30.24; }; acl your-ISP-dns { 199.177.202.10; 204.95.224.200; };

    The following allow-transfer option directive placed in your named.conf file will default all defined zones to only allow transfers for the defined hosts:

    options { allow-transfer { your-company-dns; your-ISP-dns; }; };

    You can override the allow-transfer statement in the options directive by placing the allow-transfer statement in the zone definition:

    zone "yourdomain.com" { type master; file "db.yourdomain-com"; allow-transfer { 172.16.30.12; 192.168.71.200; }; }

    The default allow-transfer option will prevent zone transfers to hosts not specified in the ACLs. However, if you want to restrict all zone transfers on your secondary servers and any secondary zones on your primary servers, use predefined match list none. This can be accomplished with the following allow-transfer directive in your zone definitions:

    zone "yourdomain.com" { type slave; file "db.yourdomain-com.s"; masters { 192.168.71.1; }; allow-transfer { none; }; };

    Finally, because you will be allowing recursive queries through your servers, it's best to enable access control lists for your internal networks. Using a nested, named acl with the allow-query option in the zone definition, you can then restrict recursive queries to internal hosts only as seen in the following example:

    acl internal-net { 192.168.71.0/24; }; acl dmz-net { 172.16.30.0/24; }; acl trusted-hosts { localhost; internal-net; dmz-net; }; zone "yourdomain.com" { type master; file "db.yourdomain-com" allow-query { trusted-hosts; }; };

    Que's Concise Guide to DNS and BIND by Nicolai Langfeldt is a wonderful resource to further grok BIND configuration and maintenance.

    Tighten Sendmail Default Options

    Send mail comes with just about every UNIX/Linux installation as the default mail transfer agent (MTA). As a result of being so widely installed, it has been estimated that sendmail handles a majority of the email on the Internet. Because it runs as suid root, sendmail exploits affect millions of machines.

    sendmail version 8.11.0 is available at the time of publication, and supports new features such as STARTTLS and SMTP AUTH encryption. Upgrade to the newest version available, if possible, but please make sure that you are running a version no later than version 8.9.3 because of security exploits.

    To enable the Realtime Blackhole List feature, use the following in your sendmail.mc file:

    FEATURE(rbl)dnl

    Additionally, you might want to disable the SMTP VRFY and EXPN commands in sendmail. These commands are often used by intruders to gather information about your system:

    define(´confPRIVACY_FLAGS', ´novrfy,noexpn')dnl

    There are several additional flags you can set to make sendmail have a more secure stance:

  • authwarnings—Add X-Authentication-Warning header in messages on certain conditions that might indicate mail system spoof attempts.

  • needmailhelo—Require that the sending site uses the SMTP HELO command first when connecting to send email.

  • needexpnhelo—Require that the sending site uses the SMTP HELO command before allowing any EXPN usage.

  • needvrfyhelo—Require that the sending site uses the SMTP HELO command before allowing any VRFY usage.

  • noreceipts—Disable Delivery Status Notification (DSNs) of delivery and read receipts.

  • goaway—Set all flags except restrictmailq and restrictqrun.

  • restrictmailq—Prevent users from using the mailq command to view the contents of the mail queue.

  • restrictqrun—Stop users from processing the queue.

  • Better than sendmail: Making Postfix Your MTA

    According to its Web page, Postfix's goals are "to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users."

    Postfix was primarily written by Wietse Venema of tcp_wrappers fame. Postfix was designed to be modular, thus Postfix is not a single executable like sendmail; rather, Postfix comprises a collection of specialized programs that perform specific tasks. All the programs except for the master control process (oddly called master because it runs without root privilege) run as nonprivileged users, limiting the damage an attacker can inflict on your system. Because of the speed, ease of configuration (and thus less chance of misconfiguration), and security, it is recommended that you investigate replacing sendmail with Postfix. For those of you who do not dream in sendmail.cf syntax, Postfix will make email administration both easier and more secure.

    Postfix is now distributed with most GNU/Linux and BSD releases, although it is not often installed by default. Usually, it is a simple matter of installing it via your package management system, or (in the BSD case) via the ports collection.

    If you are using an operating system that does not distribute Postfix, despair not. You can download and compile the sources easily on a development workstation and then install the binaries on your mail server. The sources, FAQs, and documentation can be found at http://www.postfix.org/

    Linux-Specific Tasks

    There are many GNU/Linux distributions out there. Each vendor has its own installation process, which usually changes between new versions of the vendor's distribution. The "forerunners" of GNU/Linux distributions are Red Hat, SuSE, TurboLinux, Mandrake, Caldera, Slackware, and Debian. That does not mean specifically that you should use any one of them because the high number of distributions allows vendors to tailor their GNU/Linux distributions to specific tasks such as embedded systems, routers, and firewalls. Take the time to carefully investigate the available distributions, and determine which best fits your needs.

    With that said, two of these general distributions stand out, but for different reasons. Red Hat, because it has had the most name recognition, and is usually the first to get any sort of corporate support in the way of commercial software or commercial technical service. Many vendors, such as Oracle, IBM, and Check Point, have released products for Red Hat-specific distributions. This does not mean that those software releases will not run on other GNU/Linux distributions, but if there is a problem, the vendor might not support your installation of its product on a non-Red Hat distribution.

    Debian is the second distribution that deserves mention. First, not because it is entirely free, but because it is maintained by a nonprofit organization made up entirely of volunteers. These volunteers are highly motivated by quality and pride in their efforts to make Debian the most stable and completely 100% free distribution available. Debian has proven to be extremely stable and easy to manage and upgrade remotely. The upgrade process is by far the easiest of any of the GNU/Linux distributions. Debian installations can be upgraded without the need for reboots, replacing every installed package and running process excepting the kernel. Additionally, the Debian packaging system and its front ends allow extremely fine-grained control over which packages, utilities, libraries, and files exist on your system. Debian also is currently available on six different architectures, with more than 3,900 included software packages to select from when installing.

    For both Debian and Red Hat installations, you should choose custom installations, and select the individual packages you want on your system. There should be no need to install development packages, any of the new KDE or GNOME desktops, and certainly not X Window. Unfortunately, neither distribution yet has a minimal secure server or firewall predefined install-set.

    During the installation process, you should choose to enable shadow password file support; choose to use MD5 hashes for the passwords rather than the normal crypt function. If you miss these options during the install, you can change them after installation. In Red Hat, use the setup utility. In Debian, you can use the shadowconfig utility to enable or disable shadow passwords. To enable MD5 hashes, you have to edit the appropriate files under /etc/pam.d to include md5 on the password lines.

    You should also enable ipchains support, even if this is an application server on the DMZ. ipchains provides additional layers of security, and allows you to protect the server from traffic should the firewall fail for some reason. A sample ipchains configuration is discussed later in the article.

    You should additionally read and monitor the security and errata/updates lists from your distribution vendor. With Debian, it is extremely easy to automatically install security updates using the apt-get utility. For Red Hat installations starting with the 6.0 release, there is the up2date utility to retrieve updated packages for your release.

    For those people who choose to install Red Hat Linux, there is a security-related project called Bastille Linux, whose aim is not just to harden your Linux installation, but to educate the administrators on how to harden the system. Bastille Linux supports Red Hat and Mandrake Linux distributions with project goals to become distribution, and UNIX flavor, agnostic. The Bastille Linux product is a set of scripts that asks a series of questions and then allows you to apply those modifications to your system. The questions describe what needs to be done, why it should be done, and why you might not want to do it. It is very educational, especially for those administrators just getting familiar with Linux. Bastille Linux can be found at http://www.bastille-linux.org/.

    Another excellent source of information for administrators is the Linux Administrator's Security Guide. It covers an extremely wide array of topics related to Linux and security. You can find the Linux Administrator's Security Guide online at http://www.securityportal.com/lasg/.

    Solaris-Specific Tasks

    Solaris has four default install-sets: Core, End-User, Developer, and Entire Distribution. Installing any install-set higher than the Core installation will enable more services than are required for DMZ servers or firewalls. In reality, you can often remove a significant percentage of the default Core install-set, depending on your server's application requirements.

    For Solaris-based servers, there are several excellent documents from Sun in its Blueprints Online archive at http://www.sun.com/software/solutions/blueprints/online.html. The following three papers are excellent starting points for building secure Solaris servers:

  • "Solaris Operating Environment Minimization for Security: A Simple, Reproducible and Secure Application Installation Methodology" by Alex Noordergraaf and Keith Watson. Although this paper specifically covers the iPlanet Web server requirements, similar requirements are necessary for using Apache or other Web servers.

  • "Solaris Operating Environment Security" by Alex Noordergraaf and Keith Watson. An overview of general security options on a Solaris server. This paper includes some specifics for the SPARC architecture; however, most of the material is applicable to Intel architectures as well.

  • "Solaris Operating Environment Network Settings for Security" by Alex Noordergraaf and Keith Watson is another excellent paper on kernel tuning and application parameters that affect network security.

  • As a matter of fact, Sun's Blueprints Online is a wealth of whitepapers outlining Best Practices regarding Solaris Operating Environments, whether it is a DMZ Web server, firewall, or internal highly available database cluster.

    Lance Spitzner also has an excellent Solaris hardening document that details the hardening process for building a Check Point FireWall-1 firewall on several recent versions of Solaris (through version 8) for the Intel and SPARC platforms. The living document resides at http://www.enteract.com/~lspitz/armoring.html.

    Finally, there is an equivalent to the Bastille-Linux hardening scripts for Solaris called TITAN. The TITAN project and documentation can be found at http://www.fish.com/titan/.

    OpenBSD-Specific Tasks

    This section concentrates on OpenBSD 2.7, which is one of the three more famous BSD variants; the others being NetBSD and FreeBSD. Each variant has focused on a different problem: NetBSD is the most portable, FreeBSD has the best performance, and OpenBSD is the most secure.

    One of the great strengths of OpenBSD is the highly secure default stance of a default install of OpenBSD. The OpenBSD Web site claims "three years without a remote hole in the default install, only one localhost hole in two years in the default install." Almost all services are disabled until the administrator has enough experience to properly configure them.

    Two additional changes necessary for an OpenBSD box to become a firewall are to disable sendmail and enable IP filter support. Both changes are made to the same file, /etc/rc.conf. To disable sendmail, change

    sendmail_flags="-q30m"

    to

    sendmail_flags=NO

    To enable IP filter support, you must change

    ipfilter=NO

    to

    ipfilter=YES

    Additionally, if you will be doing Network Address Translation (NAT), providing transparent proxying, or providing support for FTP, you must enable the ipnat option by setting ipnat=YES. Syntax for IP filters will be covered briefly later in the chapter.


    OpsMgr 2007 R2 hardware, software, security requirements | killexams.com real questions and Pass4sure dumps

    Solutions provider takeaway: Take a look at information on how to use OpsMgr 2007 R2, get an overview of OpsMgr component requirements and become an expert on advanced OpsMgr concepts and security. Learning about OpsMgr 2007 R2 component requirements, such as hardware and software, will help solutions providers ensure OpsMgr is functional and reliable. They will also need to be aware of support for non-Windows devices, capacity limits and how to keep track of the size of the OpsMgr 2007 R2 database.

    Understanding How to Use OpsMgr

    Using OpsMgr is relatively straightforward. The OpsMgr monitoring environment can be accessed through three sets of consoles: an Operations Console, a Web console, and a command shell. The Operations Console provides full monitoring of agent systems and administration of the OpsMgr environment, whereas the Web console provides access only to the monitoring functionality. The command shell provides command-line access to administer the OpsMgr environment.

    Managing and Monitoring with OpsMgr

    As mentioned in the preceding section, two methods are provided to configure and view OpsMgr settings. The first approach is through the Operations Console and the second is through the command shell.

    Within the Administration section of the Operations Console, you can easily configure the security roles, notifications, and configuration settings. Within the Monitoring section of the Operations Console, you can easily monitor a quick "up/down" status, active and closed alerts, and confirm overall environment health.

    In addition, a web-based monitoring console can be run on any system that supports Microsoft Internet Explorer 6.0 or higher. This console can be used to view the health of systems, view and respond to alerts, view events, view performance graphs, run tasks, and manage Maintenance mode of monitored objects. New to OpsMgr 2007 R2 is the ability to display the Health Explorer in the Web console.

    Reporting from OpsMgr

    OpsMgr management packs commonly include a variety of preconfigured reports to show information about the operating system or the specific application they were designed to work with. These reports are run in SQL Reporting Services. The reports provide an effective view of systems and services on the network over a custom period, such as weekly, monthly, or quarterly. They can also help you monitor your networks based on performance data, which can include critical pattern analysis, trend analysis, capacity planning, and security auditing. Reports also provide availability statistics for distributed applications, servers, and specific components within a server.

    Availability reports are particularly useful for executives, managers, and application owners. These reports can show the availability of any object within OpsMgr, including a server (shown in Figure 23.5), a database, or even a service such as Windows Server 2008 R2 that includes a multitude of servers and components. The Availability report shown in Figure 23.5 indicates that the SP server was down on 9/29/2009 for about 4.17% of the time or just slightly over 1 hour. The rest of the time it had been up.

    FIGURE 23.5 Availability report.

    The reports can be run on demand or at scheduled times and delivered via email. OpsMgr can also generate HTML-based reports that can be published to a web server and viewed from any web browser. Vendors can also create additional reports as part of their management packs.

    Using Performance Monitoring

    Another key feature of OpsMgr is the capability to monitor and track server performance. OpsMgr can be configured to monitor key performance thresholds through rules that are set to collect predefined performance data, such as memory and CPU usage over time.

    Rules can be configured to trigger alerts and actions when specified performance thresh-olds have been met or exceeded, allowing network administrators to act on potential performance issues. Performance data can be viewed from the OpsMgr Operations Console.

    In addition, performance monitors can establish baselines for the environment and then alert the administrator when the counter subsequently falls outside the defined baseline envelope.

    Using Active Directory Integration

    Active Directory integration provides a way to install management agents on systems without environmental-specific settings. When the agent starts, the correct environmental settings, such as the primary and failover management servers, are stored in Active Directory. The configuration of Active Directory integration provides advanced search and filter capabilities to fine-tune the dynamic assignment of systems.

    Integrating OpsMgr Non-Windows Devices

    Network management is not a new concept. Simple management of various network nodes has been handled for quite some time through the use of the SNMP. Quite often, simple or even complex systems that utilize SNMP to provide for system monitoring are in place in an organization to provide for varying degrees of system management on a network.

    OpsMgr can be configured to integrate with non-Windows systems through monitoring of syslog information, log file data, and SNMP traps. OpsMgr can also monitor TCP port communication and website transaction sequencing for information-specific data management.

    New to OpsMgr 2007 R2 is the ability to monitor non-Microsoft operating systems such as Linux and UNIX, as well as the applications that run on them such as Apache and MySQL. OpsMgr monitors the file systems, network interfaces, daemons, configurations, and performance metrics. Operations Manager 2007 R2 supports monitoring of the following operating systems:

  • HP-UX 11i v2 and v3 (PA-RISC and IA64)
  • Sun Solaris 8 and 9 (SPARC) and Solaris 10 (SPARC and x86)
  • Red Hat Enterprise Linux 4 (x86/x64) and 5 (x86/x64) Server
  • Novell SUSE Linux Enterprise Server 9 (x86) and 10 SP1 (x86/x64)
  • IBM AIX v5.3 and v6.1
  • These operating systems are "first-class citizens" in Microsoft's parlance, meaning they are treated as equals with the Windows operating systems. Agents can be pushed from the console, operations data is collected automatically, tasks can run against the agents, and all major functions are supported.

    Special connectors can be created to provide bidirectional information flows to other management products. OpsMgr can monitor SNMP traps from SNMP-supported devices as well as generate SNMP traps to be delivered to third-party network management infrastructures.

    Exploring Third-Party Management Packs

    Software and hardware developers can subsequently create their own management packs to extend OpsMgr's management capabilities. These management packs extend OpsMgr's management capabilities beyond Microsoft-specific applications. Each management pack is designed to contain a set of rules and product knowledge required to support its respective products. Currently, management packs have been developed for APC, Cisco, Citrix, Dell, F5, HP, IBM, Linux, Oracle, Solaris, UNIX, and VMware to name a few. A complete list of management packs can be found at the following Microsoft site: http://technet. microsoft.com/en-us/opsmgr/cc539535.aspx.

    Understanding OpsMgr Component Requirements

    Each OpsMgr component has specific design requirements, and a good knowledge of these factors is required before beginning the design of OpsMgr. Hardware and software requirements must be taken into account, as well as factors involving specific OpsMgr components, such as the Root Management Server, gateway servers, service accounts, mutual authentication, and backup requirements.

    Exploring Hardware Requirements

    Having the proper hardware for OpsMgr to operate on is a critical component of OpsMgr functionality, reliability, and overall performance. Nothing is worse than overloading a brand-new server only a few short months after its implementation. The industry standard generally holds that any production servers deployed should remain relevant for three to four years following deployment. Stretching beyond this time frame might be possible, but the ugly truth is that hardware investments are typically short term and need to be replaced often to ensure relevance. Buying a less-expensive server might save money in the short term but could potentially increase costs associated with downtime, troubleshooting, and administration. That said, the following are the Microsoft-recommended minimums for any server running an OpsMgr 2007 server component:

  • 2.8GHz processor or faster
  • 20GB of free disk space
  • 2GB of random access memory (RAM)
  • These recommendations apply only to the smallest OpsMgr deployments and should be seen as minimum levels for OpsMgr hardware. More realistic deployments would have the following minimums:

  • 2--4 2.8GHz cores
  • 64-bit Windows operating system
  • 64-bit SQL Server
  • 60GB free disk space on RAID 1+0 for performance
  • 4--8GB RAM
  • Operations Manager 2007 R2 is one of Microsoft's most resource-intensive applications, so generous processor, disk, and memory are important for optimal performance. Future expansion and relevance of hardware should be taken into account when sizing servers for OpsMgr deployment, to ensure that the system has room to grow as agents are added and the databases grow.

    Determining Software Requirements

    OpsMgr components can be installed on either 32-bit or 64-bit versions of Windows Server 2003, Windows Server 2008, or Windows Server 2008 R2. The database for OpsMgr must be run on a Microsoft SQL Server 2005 or Microsoft SQL Server 2008 server. The database can be installed on the same server as OpsMgr or on a separate server, a concept that is discussed in more detail in following sections.

    OpsMgr itself must be installed on a member server in a Windows Active Directory domain. It is commonly recommended to keep the installation of OpsMgr on a separate server or set of dedicated member servers that do not run any other applications that could interfere in the monitoring and alerting process.

    A few other requirements critical to the success of OpsMgr implementations are as follows:

  • Microsoft .NET Framework 2.0 and 3.0 must be installed on the management server and the reporting server.
  • Windows PowerShell.
  • Microsoft Core XML Services (MSXML) 6.0.
  • WS-MAN v1.1 (for UNIX/Linux clients).
  • Client certificates must be installed in environments to facilitate mutual authentication between nondomain members and management servers.
  • SQL Reporting Services must be installed for an organization to be able to view and produce custom reports using OpsMgr's reporting feature.
  • OpsMgr Backup Considerations

    The most critical piece of OpsMgr, the SQL databases, should be regularly backed up using standard backup software that can effectively perform online backups of SQL databases. If integrating these specialized backup utilities into an OpsMgr deployment is not possible, it becomes necessary to leverage built-in backup functionality found in SQL Server.

    Understanding Advanced OpsMgr Concepts

    OpsMgr's simple installation and relative ease of use often belie the potential complexity of its underlying components. This complexity can be managed with the right amount of knowledge of some of the advanced concepts of OpsMgr design and implementation.

    Understanding OpsMgr Deployment Scenarios

    As previously mentioned, OpsMgr components can be divided across multiple servers to distribute load and ensure balanced functionality. This separation allows OpsMgr servers to come in four potential "flavors," depending on the OpsMgr components held by those servers. The four OpsMgr server types are as follows:

  • Operations database server -- An operations database server is simply a member server with SQL Server installed for the OpsMgr operations database. No other OpsMgr components are installed on this server. The SQL Server component can be installed with default options and with the system account used for authentication. Data in this database is kept for 7 days by default.
  • Reporting database server -- A reporting database server is simply a member server with SQL Server and SQL Server Reporting Services installed. This database stores data collected through the monitoring rules for a much longer period than the operations database and is used for reporting and trend analysis. This database requires significantly more drive space than the operations database server. Data in this data-base is kept for 13 months by default.
  • Management server -- A management server is the communication point for both management consoles and agents. Effectively, a management server does not have a database and is often used in large OpsMgr implementations that have a dedicated database server. Often, in these configurations, multiple management servers are used in a single management group to provide for scalability and to address multiple managed nodes.
  • All-in-one server -- An all-in-one server is effectively an OpsMgr server that holds all OpsMgr roles, including that of the databases. Subsequently, single-server OpsMgr configurations use one server for all OpsMgr operations.
  • Multiple Configuration Groups

    As previously defined, an OpsMgr management group is a logical grouping of monitored servers that are managed by a single OpsMgr SQL database, one or more management servers, and a unique management group name. Each management group established operates completely separately from other management groups, although they can be configured in a hierarchical structure with a top-level management group able to see "connected" lower-level management groups.

    The concept of connected management groups allows OpsMgr to scale beyond artificial boundaries and also gives a great deal of flexibility when combining OpsMgr environments. However, certain caveats must be taken into account. Because each management group is an island in itself, each must subsequently be manually configured with individual settings. In environments with a large number of customized rules, for example, such manual configuration would create a great deal of redundant work in the creation, administration, and troubleshooting of multiple management groups.

    Deploying Geographic-Based Configuration Groups

    Based on the factors outlined in the preceding section, it is preferable to deploy OpsMgr in a single management group. However, in some situations, an organization needs to divide its OpsMgr environment into multiple management groups. The most common reason for division of OpsMgr management groups is division along geographic lines. In situations in which wide area network (WAN) links are saturated or unreliable, it might be wise to separate large "islands" of WAN connectivity into separate management groups.

    Simply being separated across slow WAN links is not enough reason to warrant a separate management group, however. For example, small sites with few servers would not warrant the creation of a separate OpsMgr management group, with the associated hardware, soft-ware, and administrative costs. However, if many servers exist in a distributed, generally well-connected geographical area, that might be a case for the creation of a management group. For example, an organization could be divided into several sites across the United States but decide to divide the OpsMgr environment into separate management groups for East Coast and West Coast, to roughly approximate their WAN infrastructure.

    Smaller sites that are not well connected but are not large enough to warrant their own management group should have their event monitoring throttled to avoid being sent across the WAN during peak usage times. The downside to this approach, however, is that the reaction time to critical event response is increased.

    Deploying Political or Security-Based Configuration Groups

    The less-common method of dividing OpsMgr management groups is by political or security lines. For example, it might become necessary to separate financial servers into a separate management group to maintain the security of the finance environment and allow for a separate set of administrators.

    Politically, if administration is not centralized within an organization, management groups can be established to separate OpsMgr management into separate spheres of control. This would keep each OpsMgr management zone under separate security models.

    As previously mentioned, a single management group is the most efficient OpsMgr environment and provides for the least amount of redundant setup, administration, and troubleshooting work. Consequently, artificial OpsMgr division along political or security lines should be avoided, if possible.

    Sizing the OpsMgr Database

    Depending on several factors, such as the type of data collected, the length of time that collected data will be kept, or the amount of database grooming that is scheduled, the size of the OpsMgr database will grow or shrink accordingly. It is important to monitor the size of the database to ensure that it does not increase well beyond the bounds of accept-able size. OpsMgr can be configured to monitor itself, supplying advance notice of data-base problems and capacity thresholds. This type of strategy is highly recommended because OpsMgr could easily collect event information faster than it could get rid of it.

    The size of the operations database can be estimated through the following formula:

    Number of agents x 5MB x retention days + 1024 overhead = estimated database size

    For example, an OpsMgr environment monitoring 1,000 servers with the default 7-day retention period will have an estimated 35GB operations database:

    (1000 * 5 * 7) + 1024 = 36024 MB

    The size of the reporting database can be estimated through the following formula:

    Number of agents x 3MB x retention days + 1024 overhead = estimated database size

    The same environment monitoring 1,000 servers with the default 400-day retention period will have an estimated 1.1TB reporting database:

    (1000 * 3 * 400) + 1024 = 1201024 MB

    It is important to understand that these estimates are rough guidelines only and can vary widely depending on the types of servers monitored, the monitoring configuration, the degree of customization, and other factors.

    Defining Capacity Limits

    As with any system, OpsMgr includes some hard limits that should be taken into account before deployment begins. Surpassing these limits could be cause for the creation of new management groups and should subsequently be included in a design plan. These limits are as follows:

  • Operations database -- OpsMgr operates through a principle of centralized, rather than distributed, collection of data. All event logs, performance counters, and alerts are sent to a single, centralized database, and there can subsequently be only a single operations database per management group. Considering the use of a backup and high-availability strategy for the OpsMgr database is, therefore, highly recommended, to protect it from outage. It is recommended to keep this database with a 50GB limit to improve efficiency and reduce alert latency.
  • Management servers -- OpsMgr does not have a hard-coded limit of management servers per management group. However, it is recommended to keep the environment between three to five management servers. Each management server can support approximately 2,000 managed agents.
  • Gateway servers -- OpsMgr does not have a hard-coded limit of gateway servers per management group. However, it is recommended to deploy a gateway server for every 200 nontrusted domain members.
  • Agents -- Each management server can theoretically support up to 2,000 monitored agents. In most configurations, however, it is wise to limit the number of agents per management server, although the levels can be scaled upward with more robust hardware, if necessary.
  • Administrative consoles -- OpsMgr does not limit the number of instances of the Web and Operations Console; however, going beyond the suggested limit might introduce performance and scalability problems.
  • Defining System Redundancy

    In addition to the scalability built in to OpsMgr, redundancy is built in to the components of the environment. Proper knowledge of how to deploy OpsMgr redundancy and place OpsMgr components correctly is important to the understanding of OpsMgr redundancy. The main components of OpsMgr can be made redundant through the following methods:

  • Management servers -- Management servers are automatically redundant and agents will failover and failback automatically between them. Simply install addi-tional management servers for redundancy. In addition, the RMS system acts as a management server and participates in the fault tolerance.
  • SQL databases -- The SQL database servers hosting the databases can be made redundant using SQL clustering, which is based on Windows clustering. This supports failover and failback.
  • Root Management Server -- The RMS can be made redundant using Windows clus-tering. This supports failover and failback.
  • Having multiple management servers deployed across a management group allows an environment to achieve a certain level of redundancy. If a single management server expe-riences downtime, another management server within the management group will take over the responsibilities for the monitored servers in the environment. For this reason, it might be wise to include multiple management servers in an environment to achieve a certain level of redundancy if high uptime is a priority.

    The first management server in the management group is called the Root Management Server. Only one Root Management Server can exist in a management group and it hosts the software development kit (SDK) and Configuration service. All OpsMgr consoles communicate with the management server so its availability is critical. In large-scale envi-ronments, the Root Management Server should leverage Microsoft Cluster technology to provide high availability for this component.

    Because there can be only a single OpsMgr database per management group, the database is subsequently a single point of failure and should be protected from downtime. Utilizing Windows Server 2008 R2 clustering or third-party fault-tolerance solutions for SQL data-bases helps to mitigate the risk involved with the OpsMgr database.

    Monitoring Nondomain Member Considerations

    DMZ, Workgroup, and Nontrusted Domain Agents require special configuration; in partic-ular, they require certificates to establish mutual authentication. Operations Manager 2007 R2 requires mutual authentication, that is, the server authenticates to the client and the client authenticates to the server, to ensure that the monitoring communications are not hacked. Without mutual authentication, it is possible for a hacker to execute a man-in-the-middle attack and impersonate either the client or the server. Thus, mutual authenti-cation is a security measure designed to protect clients, servers, and sensitive Active Directory domain information, which is exposed to potential hacking attempts by the all-powerful management infrastructure. However, OpsMgr relies on Active Directory Kerberos for mutual authentication, which is not available to nondomain members.

    Note:Workgroup servers, public web servers, and Microsoft Exchange Edge Transport role servers are commonly placed in the DMZ and are for security reasons not domain members, so almost every Windows Server 2008 R2 environment will need to deploy certificate-based authentication.

    In the absence of Active Directory, trusts, and Kerberos, OpsMgr 2007 R2 can use X.509 certificates to establish the mutual authentication. These can be issued by any PKI, such as Microsoft Windows Server 2008 Enterprise CA. See Chapter 14, "Transport-Level Security," for details on PKI and Windows Server 2008 R2.

    Installing agents on DMZ servers is discussed later in this chapter in the section "Monitoring DMZ Servers with Certificates."

    Securing OpsMgr

    Security has evolved into a primary concern that can no longer be taken for granted. The inherent security in Windows Server 2008 R2 is only as good as the services that have access to it; therefore, it is wise to perform a security audit of all systems that access information from servers. This concept holds true for management systems as well because they collect sensitive information from every server in an enterprise. This includes potentially sensitive event logs that could be used to compromise a system. Consequently, securing the OpsMgr infrastructure should not be taken lightly.

    Securing OpsMgr Agents

    Each server that contains an OpsMgr agent and forwards events to management servers has specific security requirements. Server-level security should be established and should include provisions for OpsMgr data collection. All traffic between OpsMgr components, such as the agents, management servers, and database, is encrypted automatically for security, so the traffic is inherently secured.

    In addition, environments with high-security requirements should investigate the use of encryption technologies such as IPSec to scramble the event IDs that are sent between agents and OpsMgr servers, to protect against eavesdropping of OpsMgr packets.

    OpsMgr uses mutual authentication between agents and management servers. This means that the agent must reside in the same forest as the management server. If the agent is located in a different forest or workgroup, client certificates can be used to establish mutual authentication. If an entire nontrusted domain must be monitored, the gateway server can be installed in the nontrusted domain, agents can establish mutual authentication to the gateway server, and certificates on the gateway and management server are used to establish mutual authentication. In this scenario, you can avoid needing to place a certificate on each nontrusted domain member.

    Understanding Firewall Requirements

    OpsMgr servers that are deployed across a firewall have special considerations that must be taken into account. Port 5723, the default port for OpsMgr communications, must specifically be opened on a firewall to allow OpsMgr to communicate across it.

    Table 23.1 describes communication for this and other OpsMgr components.

    TABLE 23.1 OpsMgr Communication Ports

    From To Port Agent Root Management Server 5723 Agent Management Server 5723 Agent Gateway Server 5723 Agent (ACS forwarder) Management server ACS collector 51909 Gateway Server Root Management Server 5723 Gateway Server Root Management Server 5723 Management or Gateway server Unix or Linux computer 1270 Management or Gateway server Unix or Linux computer 22 Management server Operations Manager database 1433 Management server Root Management Server 5723, 5724 Management server Reporting data warehouse 1433 Management server ACS collector ACS database 1433 Operations console Root Management Server 5724 Operations console (reports) SQL Server reporting services 80 Reporting server Root Management Server 5723, 5724 Reporting server Reporting data warehouse 1433 Root Management Server Operations Manager database 1433 Root Management Server Reporting data warehouse 1433 Web console browser Web console server 51908 Web console server Root Management Server 5724

    The firewall port for the agents is the port that needs to be opened most often, which is only port 5723 from the agent to the management servers for monitoring. Other ports, such as 51909 for ACS, are more rarely needed. Figure 23.6 shows the major communications paths and ports between OpsMgr components.

    FIGURE 23.6 Communications ports.

    Outlining Service Account Security

    In addition to the aforementioned security measures, security of an OpsMgr environment can be strengthened by the addition of multiple service accounts to handle the different OpsMgr components. For example, the Management Server Action account and the SDK/Configuration service account should be configured to use separate credentials, to provide for an extra layer of protection in the event that one account is compromised.

  • Management Server Action account -- The account responsible for collecting data and running responses from management servers.
  • SDK and Configuration service account -- The account that writes data to the operations database; this service is also used for all console communication.
  • Local Administrator account -- The account used during the agent push installation process. To install the agent, local administrative rights are required.
  • Agent Action account -- The credentials the agent will run as. This account can run under a built-in system account, such as Local System, or a limited domain user account for high-security environments.
  • Data Warehouse Write Action account -- The account used by the management server to write data to the reporting data warehouse.
  • Data Warehouse Reader account -- The account used to read data from the data warehouse when reports are executed.
  • Run As accounts -- The specific accounts used by management packs to facilitate monitoring. These accounts must be manually created and delegated specific rights as defined in the management pack documentation.

    You may jump straight to the month of your choice: January, February, March, April, May, June, July, August, September, October, November, or December.

    The Linux Weekly News begins publication. The very first issue, dated January 22, was a just a tiny hint of what LWN was to become. Since then we've gotten better at it, and the Linux world has gotten much more complicated. It has been an interesting adventure.

    [Netscape]Netscape announces that they will release the source to their browser under a free software license. This almost certainly remains one of the most important events of the year; it opened a lot of eyes to what Linux and free software could provide.

    [RHAD] Red Hat Advanced Development Labs is founded. It has since become one of the higher-profile places where people are paid to develop free software, and an important component of the GNOME project. RHAD is able to attract developers like "Rasterman" and Federico Mena Quintero.

    The Stampede Linux distribution is announced. Actually, this happened in December, but the news took a while to spread... Stampede positions itself as a high-performance "real Linux hacker's" distribution.

    Word gets out that parts of the blockbuster film "Titanic" were rendered on Alpha machines running Linux. This was another important step in the "legitimization" of Linux - everybody had heard of The Titanic, and some of its success seemed to rub off on everything associated with it.

    [Qube] The Cobalt Qube is announced and immediately becomes a favorite in the trade press due to its high performance, low price, and cute form factor. Cobalt's Linux engineering is done by none other than David Miller, source of much that is good in the Linux kernel.

    [prize] The Linux user community wins InfoWorld's technical support award; Red Hat 5.0 also won their Operating System award. But it was the tech support award that truly opened some eyes; everybody had been saying that Linux had no support. This was the beginning of the end of the "no support" argument.

    [opensource] Red Hat announces that their installation support staff is running behind. They are a victim of their own success, and ask for patience while they get their act together.

    Linux according to Jesse Berst "I think it's great if you are willing to promote Linux to your boss. As long as you are aware of the risk you are taking. The risk of getting fired." (Feb. 16). "Is a Linux takeover likely? Give me a break. Of course not." (June 23). "I personally think Windows NT will be the mainstream operating system within a few years." [...] "My belief: Linux will never go mainstream" (Sep. 9). "I've always said that Linux could become a serious challenger to Microsoft's Windows NT." Sep. 28).

    Eric Raymond and friends come up with the "open source" term. They apply for trademark status, and put up the opensource.org web site. Thus begins the formal effort to push Linux for corporate use.

    Linus Torvalds and Richard Stallman win the EFF Pioneer award. The award recognizes their contributions to electronic freedom. Strangely, all mention of this seems to have vanished from the Electronic Frontier Foundation web site.

    Caldera 1.2 is released. Unlike Red Hat, which had been shipping libc6 based systems for some time, Caldera sticks with the tried and true libc5.

    The OpenBIOS project is launched, in the belief that no system is free if it depends on proprietary BIOS code. A web page is set up for the project.

    [GGI] Major battles rage over whether GGI belongs in the Linux Kernel. GGI, the "Generic Graphics Interface," seeks to produce a better defined, better supported interface to video cards on Linux and other systems. Interestingly, GGI had made no request for kernel inclusion at this time. No resolution was reached, but better communications with a number of kernel hackers did result from this episode.

    The Linux General Store opens; this is "the first walk-in Linux store." (Web page here).

    [Learning tree] Learning Tree, International adds a Linux administration course to their lineup. This course is offered frequently in the U.S. and Britain. "The quality of Linux software has improved dramatically, making it a low-cost, reliable, supported computing platform appropriate for the business environment."

    Consumer advocate Ralph Nader asks the large PC vendors (Dell, Gateway, Micron...) to offer non-Microsoft systems, including systems with Linux installed. (See InfoPolicy Notes).

    Sun offers 70% discounts for people interested in "upgrading" from Linux to Solaris.

    [Debian] [Sendmail logo] Bruce Perens, once leader of the Debian project, quits entirely in the wake of disagreements on how the project should proceed.

    Sendmail, Inc. is formed by Eric Allman, in an attempt to make money selling sendmail support services while keeping the basic sendmail code free.

    John Kirch releases his "Microsoft Windows NT Server 4.0 versus Unix" paper. This paper remains one of the best advocacy pieces out there, and should be required reading for anybody contemplating deployment of either technology.

    [Mozilla] The Mozilla source code hits the net. Netscape throws a huge party. The code is downloaded all over the world, and people start hacking. New features, such as strong encryption and a Qt port, are added almost immediately.

    Linus makes Inter@ctive Week's "25 Unsung Heroes of the Net" list. He is in good company, joining names like Steven Bellovin, Van Jacobson, Peter G. Neumann, and others. April was maybe about the last time that Linus could be said to be an "unsung" hero.

    Linus announces Linux 2.1.92 and declares a 2.1 feature freeze. The announcment goes as far as to say "...there are probably still bugs with some of the new code, but I'll freeze new features for the upcoming 2.2 kernel." This freeze turned out to be rather slushy, to say the least.

    The Open Group announces a new licensing policy for the X window system. New versions of X will be proprietary and only available to paying customers. They immediately withhold some security bugfixes from general distribution. XFree86 decides that it can not live with the new licensing, and declares its intent to go its own way.

    [NPR] Linux is covered by the U.S. National Public Radio news, marking one of its first appearances in the mainstream, non-technical press.

    O'Reilly holds the "first ever" Free Software Summit, featuring Larry Wall, Brian Behlendorf, Linus Torvalds, Guido van Rossum, Eric Allman, Phil Zimmermann, Eric Raymond, and Paul Vixie.

    The Linux Weekly News daily updates page debuts. Despite LWN's intent to keep the its weekly focus, the daily page eventually exceeds the weekly newsletter in traffic. The Linux events calendar is also announced.

    Linus 3.0 is announced; the birth of Linus's second daughter causes great joy, and substantial disruption in kernel development as all work stops and many patches get lost. Some grumbling results as it becomes clear just how dependent the entire process is on Linus's continual presence.

    RH support partner logo[Avalon] Red Hat announces their commercial support program, based on a worldwide network of "support partners," of which Eklektix, Inc., the producer of the Linux Weekly News, is one.

    The Avalon Beowulf cluster at Los Alamos goes on line and immediately powers itself into the list of the fastest computers on the planet.

    Eric S. Raymond publishes "Homesteading the Noosphere" on the web; This paper gives his view of how economics of open source software can work.

    Kernel hacker Alan Cox goes to work for Red Hat.

    Bruce Perens proposes a new Linux distribution (proposal here) based on his experience with Debian. This distribution never comes about, but much of what's there later gets folded into the Linux Standard Base project.

    [Project Heresy C|Net's "Project Heresy" starts a high-profile attempt to work using only Linux. The result was a long series of articles and "radio" programs, all on the Project Heresy page.

    Sun Microsystems joins Linux International.

    [Google] The "Google" search engine pops up. Not only is it one of the best search engines around, but it's based on Linux and features a Linux-specific search page.

    Sm@rt Reseller reports that Oracle and Informix have no plans to support Linux. "In fact, many doubt that Linux-no matter how stable or how cheap-can ever compete in the corporate marketplace alongside the well-funded Windows NT and Solaris." (article here).

    [SuSE] The SuSE 5.2 distribution is released.

    [Corel] Corel formally embraces Linux. The Netwinder products are featured, and they pledge their support for the Linux system.

    The Association Francophone des Utilsateurs de Linux et des Logiciels Libres (AFUL) is formed in France. AFUL promptly becomes a force in French computer circles.

    O2 Big databases start to arrive. Support for Linux is announced by Computer Associates for their Ingres system, and by Ardent Software for their O2 object database.

    The Linux Core/Layers project was announced and became the first in a series of attempts at creating standards for Linux systems. The Core/Layers page still exists, but this project is no longer active in this form.

    "But Linux is a communist operating system in a capitalist society. Its popularity is going to lead toward its fragmentation....The big problem with Linux is that it has no apparent direction. It's in the right place at the right time, but its 15 minutes are nearly up." (PC Week, May 22).

    The Linux Weekly News moved to its own domain at lwn.net.

    A proposal goes out to create the Linux Standard Base (LSB) project. This proposal, signed by a large number of Linux luminaries, was discussed at Linux Expo and formed into a project, with Bruce Perens at the head. Numerous editorials were written and posted on FreshMeat; the list can be found on the LSB web page. The LSB then disappeared from view for a few months.

    And, yes, Linux Expo was held; a good time was had by all.

    Red Hat 5.1 was released and immediately started accumulating rather more than the usual number of updates (partly as a result of the Linux Security Audit program). There was talk of "Red Hat 5.1 service pack 1" as a result. 5.1 did eventually stabilize into a solid release.

    "First, let me say that I am uniquely unqualified to write about this week's topic. Like most of you, I've never used Linux....Linux has a snowball's chance in hell of making perceptible inroads against Windows." (The infamous John Dodge hatchet job, PC Week, June 8).

    The Open Group offers the possibility of Unix 98 certification to Linux at the Uniforum meeting. The resulting press release says "Since the Linux OS is proving to be increasingly stiff competition for NT in this marketspace, it's in the best interest of all Unix vendors for Linux to get branded so that it may compete more effectively and keep the low end UNIX 98-compliant." Very little is heard thereafter.

    The Gartner Group says there is little hope for free software. "...these operating systems will not find widespread use in mainstream commercial applications in the next three years, nor will there be broad third-party application support."

    [Wilbur] The Gimp 1.0 is released. This long-awaited release of one of Linux's highest profile tools did not disappoint.

    Stable kernel 2.0.34 is released after a long prepatch series.

    [Beowulf] The Beowulf web site shuts down temporarily due to concerns about U.S. export restrictions. Suddenly anybody can create a supercomputer, and people are getting worried. See this Dr. Dobbs article for some more background. Shortly thereafter the site (www.beowulf.org) is back up as if nothing had happened.

    The Datapro study comes out showing that Linux has the highest user satisfaction of any system; it also shows Linux to be the only system other than NT that is increasing market share.

    "Like a lot of products that are free, you get a loyal following even though it's small. I've never had a customer mention Linux to me." (Bill Gates in PC Week, June 25).

    [Netwinder] Corel launches the Netwinder DM with this press release.

    Debian 2.0 goes into beta test after numerous delays.

    [Adaptec] Adaptec reverses its longstanding nondisclosure policy and announces support for Linux. The initial deal was with Red Hat; other distribution vendors have since then announced agreements with Adaptec.

    The Chinese Linux Extension project begins; this project is doing a Chinese localization of Linux. (Web page (mix English/Chinese) here).

    IBM announces that it will distribute and support the Apache web server, after working a deal with the Apache team.

    [Rocket]

    The Silicon Valley Linux Users Group holds "The Great Linux Revolt of 1998", turning Microsoft's Windows 98 product launch celebration into a Linux publicity event at two high-profile retail outlets.

    Not content with that, The Silicon Valley Linux Users Group Launches Windows 98...on a rocket.

    The UK Linux Developers' Conference is held in Manchester (basic web page here).

    Rumors of a merger between Caldera and Red Hat circulate. It hasn't happened yet...

    The desktop wars rage as KDE and GNOME advocates hurl flames at each other. Linus gets in on the act, saying that KDE is OK with him. Those who are feeling nostalgic can head over to this Slashdot discussion just to see how much fun it really was.

    In this context, KDE 1.0 is released. The first stable release of the K Desktop Environment proves popular, despite the complaints from those who do not like the licensing of the Qt library.

    NC World magazine shuts down with Nicholas Petreley's devastating criticism of Windows NT. The article, (still available on the net), concludes that Windows NT 5 (now "Windows 2000") can only be an absolute disaster.

    Stable kernel 2.0.35 is released.

    The Internet Operating System Counter goes online and finds, after querying hundreds of thousands of hosts, that Linux has the largest web server market share of any operating system out there. The results are available on the Internet Operating System Counter page.

    LinuxPPC 4.0 is released.

    "IBM, Informix, and Sybase also have no intentions of releasing versions of their databases on Linux, company representatives said." (InfoWorld, July 6)

    [Oracle] Oracle announces support for Linux in this press release. They promise to make a trial version available by the end of 1998, a deadline they beat by months. This, seemingly, was one of the acid tests for the potential of long-term success for Linux; a great deal of attention resulted from this announcement.

    [Informix] Informix announces support for Linux on almost the same day with a press release of their own.

    The SVLUG/Taos "Future of Linux" panel is held featuring Linus and numerous other luminaries. (Writeup here). Among other things, this conference is where Intel first started making serious noises about supporting Linux.

    "When I heard that Steve Ballmer was promoted to the office of president at Microsoft, I couldn't help but wonder if he was being set up to take the fall when Windows NT 5.0 proves to be a catastrophic market failure and Linux supplants Windows NT as the future server operating system of choice."(Nicholas Petreley, InfoWorld, July 27).

    [Forbes cover] Linus appears on the cover of Forbes magazine. A lengthy story presents Linux in a highly positive manner, and brings the system to the attention of many who had never heard of it before. Linux begins to become a household word. (Yes, it was the August 10 issue, but it came out in July).

    The first release of the Mandrake distribution is announced. Mandrake is a version of the Red Hat distribution with international language support and KDE added.

    Stampede distribution 0.86 is released.

    Debian 2.0 is released with this announcement. It is a huge distribution, containing over 1500 packages and requiring at least two CD's to hold it.

    MkLinux distribution DR3 is released, announced thusly.

    Caldera releases Netware for Linux 1.0 (product info here).

    The EiffelBase library is released under an open source license; this library had previously been proprietary. (Info here).

    Red Hat announces (again) that their installation support staff is running behind (again). Their note on the topic asks for patience while they get their act together.

    The Open Source Initiative is formed by Bruce Perens, Eric Raymond, Ian Murdock, and Tim Sailer (Russ Nelson and Chip Salzenberg join the board a month later). Its purpose, among others, is to manage the "open source" trademark.

    Richard Stallman calls for the creation of free documentation for free software in this message to info-gnu.

    [GNOME] GNOME 0.25 is released; this release is codenamed Drooling Macaque.

    The Linux Compatibility Standards project is formed as a cooperative venture between Red Hat and Debian. This project (announcement) was formed out of an increasing frustration with the progress of the Linux Standard Base, which was having trouble finding consensus on its goals.

    Bruce Perens then leaves the Linux Standard Base project and, for a while, dropped out of the free software world entirely.

    Software in the Public Interest (SPI) chooses its new officers, recovering from the departure of most of its board. The new folks are Ian Jackson, Martin Schulze, Dale Scheetz and Nils Lohner; here's their announcement on the subject.

    [LSB] Red Hat puts out a paper on why they do not like the Qt license and why they will not be including KDE anytime soon. The paper is still available on Red Hat's web site.

    The Linux Standards Association appears out of nowhere and claims that they will produce the real standard for Linux systems. The LSA draws almost universal condemnation and slowly fades out of existence, but not before generating a fair amount of press saying that the Linux community is hostile to standards. One good effect of their presence may have been to help drive the Linux Compatibility Standards and Linux Standard Base projects to merge back together and get serious about producing something.

    "Organizations should not consider deployment of NT v.5.0 prior to 2001. We believe organizations are better-served in the interim by evaluating the costs and benefits of using alternative products and not waiting on NT v.5.0 to emerge from 'vaporware' status."(Gartner Group, August 11)

    Red Hat makes the development version of their distribution available as "RawHide".

    "Personally, I think open-source software needs a grown-up to step in and lead it without all this petty bickering."(Nicholas Petreley, InfoWorld, August 24).

    Michael McLagan, a founder of the LSA, challenges the validity of the Linux trademark. Linux International responded with a bit of lawyer action, causing the withdrawal of the challenge and the insertion of trademark ® symbols on the (now defunct) LSA web site.

    Kernel 2.1.115 is released; Linus calls a code freeze, for real, this time. Sort of.

    The Linux Internet Server Administration Guide project starts up with a page at lisa.8304.ch.

    Linux Magazine France debuts as "the" French print magazine on Linux (information here).

    Stackguard/Immunix 5.1 is released. StackGuard is actually a version of gcc modified to protect against stack overrun attacks; Immunix is a version of the Red Hat distribution built with this compiler.

    Microsoft's Steve Ballmer admits that they are "worried" about free software and suggests that some of the NT source code may be made available to developers.

    [SuSE] SuSE 5.3 (English version) is released.

    [Caldera] Caldera splits into two separate companies. "Caldera Systems," under Ransom Love, now handles the Linux business, while "Caldera Thin Clients" does the embedded systems. (Press release here).

    "The Linux community, a temporary, self-managed gathering of diverse individuals engaged in a common task, is a model for a new kind of business organization that could form the basis for a new kind of economy."(Harvard Business Review, September)

    SuSE stops international shipments of their 5.3 release after installation problems turn up for a small percentage of users.

    [UDI] The Uniform Driver Interface (UDI) project bursts on the Linux scene with a suggestion that maybe Linux developers would like to produce lots of drivers for the UDI interface. A free reference implementation for Linux is promised, but enthusiasm among the Linux community seems low.

    SuSE announces their "Office Suite 99" product, which is a bundling of ApplixWare, KDE, and other good stuff. This product gets a fair amount of attention as possible competition to Microsoft on the desktop.

    [DB2] IBM announces support for DB2 under Linux. (Press release here).

    [Sybase] Sybase announces support for linux (Information here). Sybase makes their database available for free download directly from the distribution vendors. With this announcement, Linux has an essentially complete portfolio of database products.

    Dell has been selling Linux-installed systems to large customers for some time reports Inter@ctive Week. This comes as a surprise to "small" customers who have been trying to get Dell to sell them Linux-installed (or at least non-Windows) machines.

    Neomagic allows the source for the driver for their video hardware to be released to the XFree86 project and freely distributed. This driver, developed by Precision Insight under the sponsorship of Red Hat, had previously been available in binary format only.

    The Open Group backs down and releases X11R6.4 under an open source license, thus ending a sad chapter in the history of free software. It is also rumored that TOG has little, if any development staff working on X at this point, meaning that it may not matter much which license they use.

    Microsoft lists Linux as a competitive threat in its annual SEC (U.S. Securities and Exchange Commission) filing. Speculation abounds that their real purpose is to affect the upcoming antitrust trial.

    [CLUE] Canadian Linux Users hold a nationwide Installfest with great success. Summaries, pictures, etc. can be found on the Installfest pages.

    Intel and Netscape (and two venture capital firms) announce minority [Intel] investments in Red Hat Software. The money is to be used to build an "enterprise support division" within Red Hat. An unbelievable amount of press is generated by this event, which is seen as a big-business endorsement of Linux.

    Intel joins Linux International.

    Net pioneer Jonathan Postel dies, depriving the world of a much-needed leader in the middle of the domain name debate.

    The International Kernel Patch is introduced, providing cryptographic capabilities in a way that does not run afoul of obnoxious national crypto export laws.

    GNOME 0.30 is released; LWN published a review of this release.

    Linuxpower.org hits the web. This site has since become a good source of Linux articles and tutorials.

    [eCos] Cygnus releases a real-time embedded operating system (eCos) under an open source license. (Press release here).

    Red Hat finds some security problems in CDE and drops it immediately as a supported product. The note they send out makes a big thing of the fact that CDE is not open source software, and thus not easily fixable.

    Caldera 1.3 is released. This version includes Sybase, KDE, and StarOffice 4.0, but sticks with libc5. Caldera also announces Linux administration training courses.

    "Gateway Inc., which has been doing certification tests with Linux for six months, most likely will install Linux across its enterprise server line next year.... Red Hat's Young expects six of the top 10 PC server makers to offer Linux on their machines by next March."(PC Week, October 5).

    [LinuxToday] LinuxToday hits the web providing another source of constantly updated Linux news. This is the first of a number of new Linux-related web publications that start up over the next month.

    Tensions explode on linux-kernel after Linus drops a few too many patches. Linus walks out in a huff and takes a vacation for a bit. Things return to normal, of course, but some people get talking. It becomes clear once again that the Linux kernel is getting to be too big for one person to keep on top of. Some ways of reducing the load on Linus are discussed, but nothing is really resolved.

    The "bootX" utility is released, and makes life much easier for PowerPC users.

    "For the moment, however, the company from Redmond, Washington, seems almost grateful for the rising profile of Linux, seeing it as an easy way of demonstrating that Windows is not a monopoly, ahead of its antitrust trial, scheduled to begin on October 15th. That may be short-sighted. In the long run, Linux and other open-source programs could cause Mr Gates much grief."(The Economist, October 3)

    Oracle8 for Linux becomes available for downloading; at 142 MB it is not something to be done lightly.

    AFUL sponsors a French nationwide installation party, the reports indicate that it was highly successful.

    Microsoft presents Linux as evidence that it does not hold a monopoly in operating systems; their release also claims that Linux was developed by "a single individual."

    Larry Wall wins the first annual Free Software Foundation award. Larry, of course, is the developer of Perl and lots of other good stuff.

    Debian decides to drop KDE from their distribution; their explanation cites worries about licensing issues.

    Novell announces that they will port NDS to Linux in cooperation with Caldera.

    [Allaire] Allaire announces that they will support Linux with "a future version" of their popular "Cold Fusion" product. (Press release here). This, evidently, is a product that quite a few people have been waiting for.

    [Compaq] Compaq is reported to be ready to support VARs installing Linux on their hardware, though it does not plan to sell Linux-installed systems directly. [LinuxWorld]

    LinuxWorld goes online, signalling the arrival of the mainstream trade press. LinuxWorld is edited by Nicholas Petreley, a long time supporter of Linux in the trade press.

    Microsoft publishes an anti-Linux "open letter" in France in what was seen by some as a beta-test of a wider FUD strategy. The letter (in French) (or translated to English) went after Linux on several fronts, and was widely and easily refuted. The definitive refutation was probably this response from AFUL (also available in English).

    Debian 2.1 goes into feature freeze.

    France Telecom invests in Cobalt Networks.

    The Mexican ScholarNet project is announced; this project will install Linux-based computer labs in 140,000 schools. (LWN coverage here). The project will be using GNOME heavily, and expects to contribute to GNOME development.

    "What I saw at the Linux Showcase was enthusiasm, the likes of which I haven't seen in the PC industry for a long time. Sure, some of it was from guys in ponytails and T-shirts, but it was also from guys in suits. Academics and scientists, but also businessmen."(PC Week, October 26).

    The Atlanta Linux Showcase was a big success. (LWN coverage here).

    Corel announces that Word Perfect 8 for Linux will be downloadable for Free for "personal use." They also announce a partnership with Red Hat to supply Linux for the Netwinder. [WineHQ]

    Corel also commits to helping the WINE development effort, a major boost for this long-awaited project. (Note from Corel here).

    [PHT] Pacific HiTech announces that they will bring TurboLinux to the U.S. market. They have long claimed to be the most popular distribution in Japan, and think it's time to head into other pastures. (Press release here).

    Www.alphalinux.org goes live, providing a single site for Alpha-related information for the first time.

    [AFUL] AFUL signs an agreement with the French Ministry of Education to support the deployment of free software in French schools. (Information (in French) here).

    Kernel hacker David Miller gets married (pictures here).

    Two internal Microsoft memos on Linux and open source software are leaked to Eric Raymond; he promptly marks them up and makes them [ExtremeLinux] public. The memos acknowledge frankly the strengths of Linux and the sort of threat that it poses to Microsoft, and suggests some possible responses. The furor in the press was just as large as one might expect. (Eric's Halloween page has the memos, links to press coverage, and translations into a number of languages).

    Extreme Linux makes a splash at Supercomputing '98, as witnessed by this list of events at the conference.

    Linux has a high profile at COMDEX, though it was not the center of the show as some pundits had expected.

    The "Eddie" software suite is released under an open source license; Eddie is a set of applications designed to help build high-availability clusters.

    The proprietary I2O bus specification is opened up, so that Linux support can be implemented. One of the big nondisclosure threats to Linux is thus removed. (Press release here).

    Red Hat 5.2 is released. This is supposed to be the last, stablest 5.x release before 6.0, which will contain the 2.2 kernel.

    Ext2 hits the net as another monthly Linux magazine.

    Informix and Apropos deploy Linux machines in over 100 Jay Jacobs clothing stores. (Press release here). Linux has truly arrived in the mainstream corporate world.

    Digital Creations releases Principia under an open source license; Principia is eventually rolled together with Bobo and Aqueduct to become Zope. An interesting angle on this release is that it was recommended by Digital Creations' venture capital investor (LWN coverage here).

    The Silicon Valley Tea Party celebrates the opening of the Microsoft campus there. (Writeup here). [StarDivision]

    StarOffice 5 for Linux is released, freely downloadable for personal use. (Information here).

    Troll Tech announces that version 2.0 of the Qt library will be released under an open source license. This license does not satisfy everyone, since it leaves Troll Tech in a special position and requires that modifications be distributed as patches. As a result, though most acknowledge that the QPL is an "open source" license, the desktop wars fail to end.

    Stable kernel 2.0.36 is released. (Linus's announcement here, release notes here).

    OpenBIOS 0.0.1 is released (announcement here).

    Slackware distribution 3.6 is released

    The CLOWN project creates a 550-node cluster, aiming for a spot in the record books (Coverage here).

    A fight erupts over the ownership of the "open source" trademark. Both Eric Raymond, in the form of the Open Source Initiative, and Software in the Public Interest claim to own the trademark. SPI has called for a "public comment" period on who should control the trademark; that period remains open as this is written.

    [BSDI] BSDI announces the ability to run Linux binaries, giving users of Linux applications "a reliable, commercially supported operating system to run them on." The implication, of course, is that such a platform had not previously been available. The really interesting point, though, is that Linux now has enough applications to make other OS vendors envious.

    Linus and Tove are guests of honor at Finland's Independence Day celebration. They get to meet the President and are voted "the most interesting couple" at the event. (Coverage here, click on "��nestys" for pictures).

    Red Hat hacker (and RPM culprit) Eric Troan gets married, no pictures (yet) available.

    The Linux Kernel Archive Mirror System is established to better get new kernels out to the world. (Mirror page here).

    [Mandrake] [Gecko]

    Mandrake distribution 5.2 is released.

    Netscape's "Gecko" rendering engine is released. Gecko is the first high-profile product out of the Netscape/Mozilla open source development effort; it is a leaner, meaner, faster, more standards-conformant web page layout engine. (Press release here).

    [YellowDog]

    The "Yellow Dog Linux" distribution for the PowerPC is announced. (Home page here).

    Corel announces a partnership with the KDE development team which will provide the KDE interface for the Netwinder. (Press release here).

    Electric Lichen announces "Die Linuxbierwanderung" - the Linux Beer Hike, a Linux-training, Alps-walking, beer-drinking adventure in Bavaria next August. (Information here).

    GNOME 1.0 enters code freeze and 0.99 betas are released.

    Compaq releases a Linux driver for its PCI RAID controller, and it is under the GPL. (Press release here).

    LibGGI 2.0 (beta) released (Announcement here).

    IBM releases some software goodies under an open source license, including the Jikes Java compiler and Secure Mailer. They also put out the beta version of DB2 for free download. [Sun]

    Sun opens up the Java license. It's still not an open source license, but things are headed in the right direction.

    Sun announces support for Linux on UltraSparc systems

    "The question is how to do it without exposing IBM and its partners," says one source familiar with IBM's plans. "With a general public license, there are some exposures with liability and how open are the patents if you modify the code. The best way to solve this is by cleaning up the license."(Sm@rt Reseller, December 18).

    Silicon Graphics joins Linux International and also announces support for Samba on their systems.

    KDE 1.1 goes into code freeze and beta releases are made available.

    IBM is said to be considering becoming a support provider for Linux according to some reports. They are held back by fears about patent and liability issues.

    The first public beta of SuSE 6.0 is released (announcement here).

    Reports say that Apple will start selling Power Macintoshes with Linux installed. [Corel]

    The "LinuxPPC on the iMac HOWTO" is released, allowing users to get Linux on those stylish blue boxes. (HOWTO here).

    The first pre-2.2 kernel is released.

    A report from IDC says that Linux shipments rose by more than 200% in 1998, and its market share rose by more than 150%. Linux has a 17% market share, and a growth rate unmatched by any other system on the market.
