Hi Andrew:

ps aux | grep ssh
ps aux | grep ftp

both show that ssh or ftp is running, but doesn't tell me who's logged in.

I think I can get the info out of auth.log, but that's going to take 
some logfile parsing to eliminate all the doorknob-rattlers trying to 
break in, and to remove the logged-out connections.

grep opened /var/log/auth.log | grep sshd

is a start.  Doesn't appear to show the SFTP or SCP sessions, tho.

I'll keep at it.  Further suggestions are welcome...
