Installation guide

138 Chapter 14. Apache Secure Server Configuration
apache-devel
The apache-devel package contains the Apache include files, header files and the APXS
utility. You will need all of these if you intend to load any extra modules, other than the
modules provided with this product. Please see the Official Red Hat Linux Reference Guide
for more information on loading modules onto your secure Web server using Apache’s
DSO functionality.
If you do not intend to load other modules onto your Apache server, you do not need
to install this package.
apache-manual
The apache-manual package contains the Apache Project’s Apache 1.3
User’s Guide in HTML format. This manual is also available on the Web at
http://httpd.apache.org/docs/.
OpenSSH packages
The OpenSSH packages provide the OpenSSH set of network connectivity tools for log-
ging into and executing commands on a remote machine. OpenSSH tools encrypt all
traffic (including passwords), so you can avoid eavesdropping, connection hijacking,
and other attacks on the communications between your machine and the remote ma-
chine.
The openssh package includes core files needed by both the OpenSSH client programs
and the OpenSSH server. The openssh package also contains scp, a secure replacement
for rcp (for copying files between machines) and ftp (for transferring files between
machines).
The openssh-askpass package supports the display of a dialog window which
prompts for a password during use of the OpenSSH agent with RSA authentication.
The openssh-askpass-gnome package contains a GNOME GUI desktop environment
dialog window which is displayed when OpenSSH programs prompt for a password. If
you are running GNOME and using OpenSSH utilities, you should install this package.
The openssh-server package contains the sshd secure shell daemon and related files.
The secure shell daemon is the server side of the OpenSSH suite, and must be installed
on your host if you want to allow SSH clients to connect to your host.
The openssh-clients package contains the client programs needed to make encrypted
connections to SSH servers, including the following: ssh, a secure replacement for rsh;
and slogin, a secure replacement for rlogin (for remote login) and telnet (for com-
municating with another host via the TELNET protocol).
For more information about OpenSSH, see Chapter 9 and the OpenSSH website at
http://www.openssh.com.
openssl-devel
The openssl-devel package contains the static libraries and the include file needed to
compile applications with support for various cryptographic algorithms and protocols.
You need to install this package only if you are developing applications which include
SSL support — you do not need this package to use SSL.
stunnel
The stunnel package provides the Stunnel SSL wrapper. Stunnel supports the SSL en-
cryption of TCP connections, so it can provide encryption for non-SSL aware daemons
