I can't seem to get X11 forwarding to work. Similar problems seem to have been reported and possibly fixed with earlier versions of openssh, but I believe I have the latest release: openssh-server-2.9p1-1 for RedHat 6.2. When I connect with ssh -v, I get: pac2: Requesting X11 forwarding with authentication spoofing. pac2: Remote: X11 forwarding disabled in server configuration file. Warning:

I still don't understand the point of authenticating myself to my own local X server when using X11 forwarding, I tried: ssh -R /tmp/.X11-unix/X0:/tmp/.X11-unix/X0 user at server # and then DISPLAY=:0 xterm and everything is working fine without the mess with xauth, so why it is required to use use xauth when doing X11 forwarding with ssh?

Dear people, since openssh-3.8.1p1 I experience problems with the automatic X11 forwarding. I installed openssh-3.9p1 yesterday hoping the problems should disappear, but alas no. It looks like the X11 autorization times out after some time, I don't know exactly but after half an hour it surely is gone. When I installed openssh-3.8.1p1 I also had opgraded openssl from 0.9.7c to 0.9.7d then,

I am using the openssh-2.1.0p3-1 RPM, but i seem to have a similar problem. the debug doesn't say anything about "X11 connection uses different authentication protocol." it just kicks me out. I can't figure it out. very strange. please CC me, because i am not subscribed. thanks, e:~> echo $XAUTHORITY XAUTHORITY: Undefined variable. e:~> xauth list

Hello, I am new at ssh, think it is a simple config problem, but have not found the error. Wenn I connect from an client (winpc vai cygwin) to server A (hpup) the connectionon and xlogo ist okay. Wenn I connect from the same client to server B I got the following error message. The problem is only by starting xlogo, the connection via ssh to Server A+B ist okay. The sshd_config on server a+b is

Hi folks, I've got a problem with X11 forwarding on an AIX 5.2 system thats stumped me.

Hi, We upgraded from 3.7.1p2 to 3.9p1. The behaviour of the X11 forwarding changed significantly, it is much slower. See below the truss output (server side which runs 3.7.1p2) an check for the timestamp (6 seconds delay). Do you have any idea what may causes this behaviour? Platform is Solaris 5.9 Generic_117171-05. Thanks in advance, Andy Kocher 19279: 9.5463 sigaction(SIGCLD,
