If you have OpenSSH installed, and you want to replace it with the ITC ssh rpm, you should remove OpenSSH, then apply the rpm described below.
If you are running RedHat Linux 7.1 or later, you're running the 2.4 kernel. Earlier releases of RedHat used the 2.2 kernel. The package to install for 2.2 is ssh-3.0.1-1.i386.rpm -- the instructions below reference a later release, but the same instructions apply to all of our ssh-3.x rpms. If you're running the 2.4 kernel, use the latest version you find in the directory (it may have been updated since this web page was last updated).
Note: You should execute the following instructions as "root." The # at the beginning of the command lines is the bash prompt.
This is a shell program which will identify any OpenSSH rpms installed and remove them from your system.
You'll see something similar to:

Please make sure you haven't specified sshd in /etc/rc.d/rc.local If you already have sshd running, you should restart it or reboot. Configuration done.
You are finished
installing the ssh clients.
The installation does not start the ssh daemon. Either reboot or run
the command:
/etc/rc.d/init.d/sshd start
to start the daemon.
