How can I find my sshd pid on connect?

I would like to make a script that grabs the pid of the sshd I spawn when I connect to a machine.

Does anyone know a good way to do this that wouldn't generate false positives?

Thanks!

Sorry, seem to have found a way to do it. If anyone else every wants to do this, here's the command I use to (later) kill my sshd (even if there's a tunnel, nothing can stop this! muwhahahaa!)

kill -9 $(cat /proc/`echo $$`/stat | cut -d " " -f 4)

In Bash this "cat /proc/`echo $$`/stat | cut -d " " -f 4" is bloat for "echo $$" :-]
Besides, it's not the PID of your sshd but your current shell. If you "ps f" it you would see:

Code:

 
sshd root (master sshd)
  \
  sshd root (privsep)
     \
     sshd $LOGNAME (pts)
        \
        shell ($$)

so the most you can get is "pgrep -U $LOGNAME -f sshd".
