I am a newbie to unix, but in playing around I noticed that the telnet command and the rlogin command do very much the same thing.  What are the differences between these and what are the best uses?

The main difference is that telnet only does password authentication, while rlogin can do password authentication or can use 'rcmd' authentication, which is essentially based on the IP address of the machine you're coming from.

If you're in a security conscience environment, you should ditch both in favor of Secure SHell (ssh).  It's now bundled with many Unix/Linux flavors, and www.openssh.com will tell you where to get free implementations for various platforms.

.. and with rlogin and ssh you can suspend the seesion, which cannot be done with telnet

SSH - when you care about security
RSH/RLOGIN - Unix to Unix with minimal security
Telnet - anything to anything with no security
