My SSH install notes.  YMMV.  Good luck

   Do the following on all your machines so you can go back and forth as needed.

      Install RPMs openssh-server and openssh-clients
      Add the following line to /etc/hosts.allow
          sshd    (using your network of course)
      Create the file /et/ssh/shosts.equiv as follows (using your hostnames of course)
            etc. etc.
      % chmod 644 /etc/ssh/shosts.equiv
      Make sure the file /etc/ssh/sshd_config contains the following line:
          HostbasedAuthentication yes
      % chmod 600 /etc/ssh/sshd_config
      Restart sshd by running '/etc/init.d/sshd restart'
      Make sure the file /etc/ssh/ssh_config contains the following lines:
          Host *
            ForwardX11 yes
            HostbasedAuthentication yes
            EnableSSHKeysign yes
      % chmod 644 /etc/ssh/ssh_config
      Create /etc/ssh/ssh_known_hosts with the RSA public keys from
        /etc/ssh/ on all machines
      % chmod 644 /etc/ssh/ssh_known_hosts
      Remove rsh RPM
      Create symlinks:
          /usr/bin/rsh->ssh, /usr/bin/rcp->scp, /usr/bin/rlogin->slogin
      Make sure firewall is open (port 22)
