Re: remote port forwarding unstable



Hi,

Here is some more info after little investigation :)

Message i get is: "Warning: remote port forwarding failed for listen port 1026"

SSH makes connection but port isn't opened and in server logs i see:

IPP-Linux:~# cat /var/log/auth.log | grep 18722
Oct 19 13:37:20 IPP-Linux sshd[18722]: error: bind: Address already in use
Oct 19 13:37:20 IPP-Linux sshd[18722]: error:
channel_setup_fwd_listener: cannot listen to port: 1026
IPP-Linux:~# cat /var/log/auth.log | grep 18737
Oct 19 13:37:47 IPP-Linux sshd[18737]: error: bind: Address already in use
Oct 19 13:37:47 IPP-Linux sshd[18737]: error:
channel_setup_fwd_listener: cannot listen to port: 1026

But i closed the previous console with ssh listening to that port, and
is no ssh process on client when i want to connect again on the same
port. So how come it still says that port is in use on server?

This happens in only 2% of the cases, very rare, i change nothing in
the way i connect or close the client, but somehow it seems that port
still hangs on server after closing ssh console ... or at least that's
what sshd says because with "netstat -an" i don't see that port busy

Thank you Rabbi for that command, next time when it happens i'll use it :)

Thanks,
Adriana
