There have been some "fun" flamewars on SLUG about using ssh-agent in the
past. Definitely useful though, and worth reading up on if you use ssh a
lot.

There's a nice little tutorial with good reasons for using ssh and
cryptographic challenge authentication here:

  http://www.utexas.edu/cc/unix/using-ssh-agent.html

Unfortunately, it doesn't describe protocol 2 and dsa keys. If you're using
a new ssh, run ssh-keygen -t dsa instead of just ssh-keygen.

Thanks Paul.
