Hi Corinna and anyone else running OpenSSH 2.9p1-1...

Help...Please others try this out for me.

I'm still having problems with ssh hanging with

ssh -f -L 5901:localhost:5900 hostname sleep 30

With ssh-2.5.2p2-3 it returns immediately and a "ps -e" about 30 seconds 
later shows that the ssh process is gone. This is assuming that I do not 
connect to port 5901.

With ssh-2.9p1-1 it returns immediately and multiple "ps -e" later show that 
the ssh process hangs around indefinately. This is assuming that I do not 
connect to port 5901.

I am also having problems with using the tunnel with 2.9p1-1. (I'm trying to 
address the hanging first, in the hope that the same problem is causing both 
symptoms.)

In all of this, I am using two Win2000 boxes. The othe box is always running 
2.5.2p2-3; I am only changing versions on my local machine.

Corinna, Regarding

ssh -f -L portnumber:localhost:portnumber hostname sleep 30

The hostname as the target is from my local point of view (public IP 
address). The localhost (or other host name) is from the target's point of 
view (LAN or loopback IP address). So this sets up a tunnel to hostname, 
using hostname. I could have substituted the LAN IP address for localhost 
with the same results. (This works fine on 2.5.2p2-3.)

Thanks,

...Karl
