Hello, I am using openssh 4.5_p1.

Is there a way to detect on an sshd server when a client has requested
port forwarding?

The only way I know of is to increase logging to verbose and grep for
lines like the following:

sshd[16236]: debug1: Local forwarding listening on 127.0.0.1 port 10000.

Is there a better way?

I realize that sending the control sequence ~# on the client side does
this. However, I am interested in similar functionality on the server
side.

Thanks.
