[ILUG] S/Key ?

[Kevin Gannon]

I have been experimenting with S/Key for those times when
ssh isnt availble or you are using someone elses machine
and you cant be sure what kind of nasty things they having running.

My questions are:
1) After running keyinit for a user is there a way to return them
      to normal telnet authentication rathet than s/key ?
2) Has anyone seen a hardware based key generator that you
     can carry in your wallet ?
