cheap secure telnet?

I have a need to have a secure telnet connection. It has to be cheap (on the order of hundreds of dollars, not thousands), but it doesn't have to be free. It also has to be low cost in terms of setup; that is, I don't want to set up a full blown Kerberos system just to get a single secure telnet link. The link is to be between two unix systems. I have root and physical access to both systems. Anyone know of such a beast? On second thought, if you have leads on stuff in the thousands of dollars range, send me them too. This /could/ turn out to be that important. -- david david@staff.udc.upenn.edu
