Ubuntu comes with an SSH agent installed and configured by default, so
there's no need to install anything.

You have to manually run 'ssh-add' to add your private SSH key (once, after you
log in) if you want git to use it without asking for your password.

For my own convenience I've created a wrapper script around ssh that
calls 'ssh-add' for me automatically, when I run ssh for the first time
with no keys in my SSH agent:

  $ cat ~/bin/ssh
  #!/bin/sh
  if [ -n "$SSH_AGENT_PID" ]; then
      # See if ssh-agent has any identities, and if not, add some
      ssh-add -l > /dev/null || ssh-add
  fi
  exec /usr/bin/ssh "$@"

HTH,

administrators will probably (rightly) recoil at letting applications on a
Windows box dictate firewall policy.
