I know that cPanel and plain redhat do not use proprietary ssh version and this will work fine for those servers. Ensim does not use special rpms like I had posted before, they use PAM authentication which is the same as cPanel does. I believe this guide should work with plesk (there is no reason it should not) but I have not personally tried so if you do please post! As always I take no responsibility if this guide screws up your server, it worked fine for me!

Updated June 19th with the latest version of openssh and openssl.

I also included the --without-zlib-version-check function which is neede for RHEL, the version is upgraded but the version numbers do not look ok with the configure script, it is nothing to worry about.

First step we will enable telnet so if something screws up you can still access the server:
