Hi, I'm trying to use ssh for port forwarding. So far ssh -L has worked just fine for that purpose. Now I want to bind the port to all interfaces, so I tried ssh -g -L. The SSH session seems to launch successfully, and the port is forwarded as expected, and it is bound to all interfaces. However, I get an error message as the remote session is launched: "bind: Address already in use". I also tried ssh -b but ssh still complains "Address already in use". I have verified that that there actually isn't any other process using the port I want. I can't find any additional info in /var/log/messages or elsewhere in /var/log/. Since the port forwarding seems to work, I'm not too worried about it, but I'd like to understand what's going on. Any ideas? ssh on the client reports its version as "OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003" and sshd on the server is openssh-server-4.5p1-6.fc7 as reported by rpm. Thanks for your help, Robert Dodier PS. Here is a debug log. There is more to to it, but I cut it off at "Address already in use". $ ssh -vvv -g -L 1069:*:1069 192.168.0.25 OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003 debug1: Reading configuration data
