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.

Use local AAA users. Of course, this doesn't scale well if you have 200
routers.

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. Telnet does not. SSH is encrypted. Telnet is not. It's pretty
easy - only use telnet if you must. Use SSH if you possible can. Of course,
this also holds true for using scp instead of ftp, although scp isn't as
widely supported, yet.

  Hello All ,Thank you for the disertations & insight into the
  possible methods of compromising an authentication attempt .

  But , I am really interested more in 'Why' each responsible
  indidvual(s) chose either telnet or ssh to manager their Core
  equipment .

  ssh
  1 )     Has been the encrypted authentication .

  telnet
  1 )     Has been legacy OS's / Equipment olny supporting telnet .

        on how many individuals responsible for IP core equipment
        recommend telnet or ssh & why particularly .I will summarize .
