Hi!

I'm trying to figure out wheter on OpenSSH is simple way to log all opened forwarded connenctions via ssh. I'm thinking about something like "Event log" in putty, but server-side:

2005-11-24 12:03:18 Opening forwarded connection to 10.x.x.x:3389
2005-11-24 12:07:26 Forwarded port closed

This is required to allow matching network activity with user accounts on ssh host. In system log on ssh host there are no traces of such logging... Is this possible at all without patching sshd code ?
