Bug#327443: X Forwarding broken on IPv6 systems without X11UseLocalhost
I have encountered exactly the problem reported in this bug and it is
causing me problems, it also appears to effect ssh port forwarding in ssh,
the setup was working perfectly until Novemeber 6th 2007 when I ran an
apt-get upgrade.
The sshd_config file has :
X11Forwarding yes
X11UseLocalhost no
GatewayPorts yes
And when I try and open a connection I can see the port is open on the
ipv6 interface :
tcp6 0 0 :::6010 :::* LISTEN
But nothing on the ipv4 interface.
I also get the same error when trying to forward a port, my client ssh
attempts to forward port 6005 on the server to port 6000 locally. Again I
can see the ipv6 interface :
tcp6 0 0 :::6005 :::* LISTEN
But nothing for ipv4, I also get :
Nov 28 09:26:05 testserver sshd[7457]: error: bind: Address already in use
In the auth.log file although netstat -an shows nothing listening and I
can run nc on the port fine after logging in
If I turn on X11UseLocalHost then my X forwading works, it has no effect
on port forwarding though.
This is ssh version 1:4.3p2-9
