I have every now and then used an ssh tunnel to forward VNC connections, but that is exceptional as far as my usage of ssh goes. Well, my setup looks pretty vanilla to me, I did not talk about more sophisticated tunneling stuff. I just have a server and a client, and need to put the XAuthLocation line into the client's config when I want X forwarding. I know found out what happened. The old boxes with working forwarding have a /usr/openwin symlink pointing to /usr/X11R6. This makes xauth being found. It belongs to x11-libs/xview, but the last xview update removed the symlink, now X forwarding fails. Still no idea why you all do NOT have the problem. Alex -- [EMAIL PROTECTED] mailing list

But I notice a change since yesterday: I now get this warning: Warning: No xauth data; using fake authentication data for X11 forwarding. Don't know what causes this, I emerged a couple of things due to world update and (still!) some problems with the expat update, but nothing which I would think has to do with ssh. Anyway, DISPLAY still does not get set. I sort of found the solution to my problem, but still do not fully understand what happened. First I thought I had to add X to the server's use flags. Looked like I then had DISPLAY set, but still got the warning about missing xauth data. When trying to start an X application, I got this: Xlib: connection to localhost:10.0 refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key xterm Xt error: Can't open display: localhost:10.0 Then I looked at the configs again, and in the man page for ssh_config I finally found this: XAuthLocation Specifies the full pathname of the xauth(1) program. The default is /usr/openwin/bin/xauth. /usr/openwin? I added XAuthLocation /usr/bin/xauth to the client's /etc/ssh/ssh_config, and now all was fine. Even without the X use flag.
