Folks,

  I need to login to our client system to do some work. Right now I
  ssh to their border system and then ssh to to another system where I need to
  do the work. How can I setup ssh tunnel so that I can login from my system
  to the target system directly.

  Current way of logging in:

    ssh -----> ssh --->
  +---+ +---+ +---+
  | A | | B | | C |
  +---+ +---+ +---+
    ssh ----------------->

  I want it as above.

  Thanks.

I haven't lost my mind,                Above opinions are mine only.
it's backed up on tape somewhere.      Others can have their own.
