Secure Shell (SSH) was built to address these faults and provide a more secure environment to work in. SSH encrypts all your traffic including your passwords when you connect to another machine over the net. SSH also replaces telnet, ftp, rsh, rlogin and rexec. Let's take a look at OpenSSH, an excellent and more importantly open source implementation of SSH. It is very well supported by the OpenBSD team and includes rock-solid SSH2 support.

OpenSSH can be downloaded from www.openssh.com. The latest version as of writing this article is 2.3.0. It is available as source tarballs or in RPM format. If you are downloading the RPM's, then you need to get the following files.
