SSH-Trouble

[Magnus Holmberg]

I have some trouble to get openssh to work with X11Forwarding.

I have installed it on 2 machines with ecactly the same configfiles.

If I use ssh from machine B to machine A X11Forwaring works but from A to
B X11Forwarding only works when I ssh as root.

The error message I get is:

X11 connection rejected because of wrong authentication.

X connection to B:12.0 broken (explicit kill or
server shutdown).

Here is the debug output from sshd:

[root at b202 /root]# sshd -d -p 2222

And when I login I get this:

Can someone help me?
