Secure Telnet

I need to set up a secure telnet between two linux machines.  I also need to deny all access to these machines to ip addresses other than those I wish to nominate. How should I do this?

OK here goes..

Firstly go to http://www.cs.hut.fi/ssh/ and download the package in the tar gzipped format. Then install it as per the instructions. Read the readme this and it should explain all you need to know. However a quick rundown would be that ssh stands for secure shell and is basically an encrypted telnet session.
To deny access for telnet to your boxes do a man on tcpd. Also man on hosts_access and this willdescribe how to setup your linux box for tcpd to deny access to certain ips or to allow access to certain ips.

Hope this helps....
