...a _less_ secure option.) The cause of the failure (for our situations) happens one a double-ssh. For example, we have people ssh'ing into our shell machine from home, and then ssh'ing to their project machines, where they run X11 programs. The code just before the xauth calls (in ssh.c:x11_get_proto) attempts to figure out if the X11 screen is local to the machine or not. It assumes that "localhost:..." means it should rewrite the display to "unix:...". However, this breaks our situation, since the display is "localhost" due to it being forwarded via sshd....

We installed openssh 3.1p1 on our Solaris 2.8 machine using gcc 2.95.2. During the installation, we modified ssh_config and sshd_config to enable X11 and agent forwarding. In sshd_config, we changed the following line to read: X11Forwarding yes In ssh_config, we changed the following two lines to read: ForwardAgent yes ForwardX11 yes Both files are set to permission readable

Hi! I'm having a difficult time getting X11 forwarding to work. Since I've read the docs completely about this, this must be an SSH bug which is likely because I'm using Gentoo as the SSH server. When trying to forward X11 connections, I get X11 connection rejected because of wrong authentication. kwrite: cannot connect to X server XXXXXXXXX:10.0 Using command ssh -Y -p 1111 -4
