Remote port forwarding problems

[Brian Olsen]

I've been trying to get remote port forwarding to work between redhat
6.2 boxes
using openssh 2.2.0p1.  One box is running the stock kernel, the other
is running
2.4.0-test9 currently.

The command I type is:

ssh -v -R 8080:localhost:8080 <remote machine>

I've also used the machine name and ip address for the local machine.

The -v shows these curious messages:

debug: read DSA private key done
debug: sig size 20 20
debug: ssh-userauth2 successfull
debug: no set_nonblock for tty fd 4
debug: no set_nonblock for tty fd 5
debug: no set_nonblock for tty fd 6
debug: channel 0: new [client-session]
debug: send channel open 0
debug: Entering interactive session.

The no set_nonblock, is that an indication?

here's the output with

ssh -v -R 8080:localhost:8080 <remote machine> -L 8081:localhost:8081

debug: ssh-userauth2 successfull
debug: Connections to local port 8081 forwarded to remote address
localhost:8081
socket: Invalid argument
debug: Local forwarding listening on 127.0.0.1 port 8081.
debug: fd 7 setting O_NONBLOCK
debug: channel 0: new [port listener]
debug: no set_nonblock for tty fd 4
debug: no set_nonblock for tty fd 5
debug: no set_nonblock for tty fd 6
debug: channel 1: new [client-session]

The local port forwarding seems to work even with the complaint.

Thanks,
Brian
