Solution; Adapted Version of Red Hat Linux 6.2 Delivers<BR>Advanced Security,
Scalability and Availability for a Reliable Internet Infrastructure</FONT></DIV>

<DIV><FONT size=2> RESEARCH TRIANGLE PARK, N.C.--(BUSINESS
WIRE)--July 10, 2000--Red Hat, Inc. (Nasdaq:RHAT), a leader in open source
Internet infrastructure<BR>solutions, today announced the Red Hat(TM) High
Availability Server 1.0, a specialized version of the award-winning Red Hat
Linux 6.2 solution.<BR> Red Hat High Availability Server is an
out-of-the-box clustering solution that delivers dynamic load balancing,
improved fault tolerance and scalability of TCP/IP<BR>based applications. It
lets users combine individual servers into a cluster, resulting in highly
available access to critical network resources such as data,
applications,<BR>network services, and more. If one server in the cluster fails,
another will automatically take over its workload. The Red Hat High Availability
Server is ideally suited<BR>to Web servers, ftp servers, mail gateways,
firewalls, VPN gateways and other front-end IP-based applications where
virtually uninterrupted service is required.<BR> "The Red Hat
High Availability Server is optimized specifically for Internet Service
Providers (ISPs) and corporate customers who want to dramatically reduce<BR>the
time needed for implementation," said Paul McNamara, vice president, products
and platforms, Red Hat, Inc. "In today's demanding Internet environment,
server<BR>failure means lost revenue and diminished customer satisfaction. With
this product, we are providing customers with a flexible, affordable, and highly
available<BR>front-end Internet infrastructure solution. Because the Red Hat
High Availability Server software can be installed on any off-the-shelf
commodity hardware that<BR>supports Linux--it offers service providers and
corporate IT departments an option for increased availability at a significant
overall cost savings."<BR> The product supports heterogeneous
network environments, allowing individual members of the cluster to run Red Hat
Linux or virtually any other OS including<BR>Solaris(R), and Windows NT(R).
Because the Red Hat High Availability Server is an open source product,
customers are free from expensive technology lock-in<BR>that often occurs with
proprietary solutions.</FONT></DIV>

<DIV><FONT size=2> New Security Features</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> The Red Hat High Availability Server has a
number of inherent security features designed specifically for high availability
Web front-end applications. Remote<BR>system access is disabled by default, and
unused network services are not installed or started in the standard
installation.<BR> The Red Hat High Availability Server can be
configured in two main ways. In Failover Services (FOS) mode, the system can be
configured as a two node cold<BR>failover cluster ideally suited for
applications where simple, affordable redundancy is needed such as firewalls,
static Web servers, DNS, and mail servers. In Linux<BR>Virtual Server (LVS)
mode, the system can be configured as an n-node cluster consisting of a two node
load balancer, which accepts requests and directs those<BR>request to one of any
number of IP-based servers based on a configurable traffic management
algorithm.</FONT></DIV>

Features and Benefits</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> -- Easy Installation: The Red Hat High
Availability Server is based on the award winning Red Hat Linux OS. Red Hat's
engineers have created a special<BR>installation-class that installs only those
packages that are needed with the clustering packages. The Red Hat High
Availability Server is installed for optimal<BR>performance--saving time and
hassle.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> -- Higher Performance and Scalability: The
Red Hat High Availability Server supports the scalability that meets the growth
demands of today's highly dynamic IP<BR>environments. The number of cluster
nodes is limited only by the hardware and network used. The product has advanced
cluster features that provide high levels of<BR>performance including an ability
to configure servers to bypass the load balancers when returning traffic back to
the client, increasing the overall performance of the<BR>cluster. Additionally,
because individual nodes can be taken off-line for maintenance or upgrades
without interruption of service, the product eliminates
costly<BR>downtime.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> -- Maximized Flexibility: The Red Hat High
Availability Server offers Systems Administrators a high degree of flexibility.
In LVS mode the product supports four<BR>load balancing methods (Round Robin,
Weighted Round Robin, Least Connections, and Weighted Least Connections) and
three traffic forwarding techniques (IP<BR>Masquerading, Tunneling and Direct
Routing). Virtually every popular IP service is supported including Web (http),
email, FTP, LDAP, DNS, and others.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> -- Increased Security: The Red Hat High
Availability Server has built-in security features designed to withstand common
attacks. Systems Administrators can<BR>setup sand traps, providing for
redirection of IP traffic from a potential attacker to a secure address. Out of
the box, finger, talk, wall, and other daemons are<BR>disabled or not installed.
In addition, multiple traffic routing and scheduling techniques along with
virtual IP addresses allow you to create a security barrier for
your<BR>network.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> -- Availability: The Red Hat High
Availability Server dramatically reduces the likelihood of system failure by
quickly detecting component server and application<BR>failures and redirecting
workload to the remaining servers in the cluster. If one or more servers fail,
others take over with minimal interruption. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> -- Excellent Value: Uses inexpensive
commodity hardware to lower your overall cost of purchasing and maintaining the
system.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> -- Support: A one year support package that
includes standard hours installation and configuration assistance and 24x7
server-down support for two Linux<BR>Routers of a Piranha cluster, configuration
of Piranha and Linux Virtual Server and any services required to run these
applications, including httpd and ftpd, and<BR>configuration of Piranha and
Linux Virtual Server for connectivity to one node behind the Linux Routers for
either httpd or ftpd service.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> Pricing and Availability</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> The price of the Red Hat High Availability
Server is $1995. It is available online at <A
href="http://www.redhat.com">www.redhat.com</A> or at select resellers. Red Hat
High Availability Server<BR>includes a full year of installation and
configuration support via telephone or the Web from Red Hat's global support
staff.</FONT></DIV>

<DIV><FONT size=2> Open Source Momentum</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> International Data Corp. (IDC) research
states that paid Linux shipments grew faster than any other server operating
system over the past two years, and their<BR>preliminary figures for 1999 show
Linux shipments hold 24.6 percent of the server operating system market, up from
15.8 in 1998. IDC also states that Red Hat<BR>Linux is by far the most popular
distribution, preferred by 68.7 percent of U.S. Linux
users.<BR> Research firm Netcraft, Inc. (<A
href="http://www.netcraft.com">www.netcraft.com</A>), states that as of May
2000, 36 percent of all public Web sites run on Linux-based operating systems,
making<BR>Linux the most popular choice for deploying public Web sites. IDC
research shows 40 percent of all spending on Linux servers is for Internet
related applications,<BR>firmly entrenching Linux servers in the Internet
infrastructure.<BR> Finally, IDC predicts that by 2002, there
will be more than 55 million handheld and notebook-style information appliance
devices and that by 2005, shipments of<BR>these appliances will exceed shipments
of PCs.<BR> Red Hat's numerous alliances with industry leaders
and the demand for Linux-based applications has created open source support from
many of the industry's<BR>leading software and hardware manufacturers, including
Compaq, Computer Associates, Dell, Hewlett-Packard, IBM, Intel, Netscape,
Novell, Oracle and SAP.</FONT></DIV>
