Sadly, there are two good reasons to use telnet to connect to core equipment, even in this day and age: 1) You have legacy equipment that does not support ssh, and/or your vendor does not include ssh in every release of code (specifically, code you need to run.) 2) Your vendor's ssh authentication creates a secure connection, and transfers the password securely, only to then send the password, unencrypted, to an authentication server for verification, making ssh moot. -Dave On 7/31/2001 at 11:54:38 -0400, Daniel Golding said: > > I believe that folks are having problems saying why they use SSH instead of > telnet, because the best practice is simply so self-evident. > > SSH gives you a measure of protection against bad people sniffing out your > passwords.
