Re: X11 forwarding problems in FreeBSD 6.2 - no xauth data? [SOLVED]

Interesting, because that was the first thing I did, but it did not solve the problem. What did solve the problem was to add the same line to my /etc/ssh/ssh_config in the Host * section. This only fixed one side of the connection, so I can connect from the FreeBSD host to the Linux hosts. On the Linux hosts, I put XAuthLocation /usr/bin/xauth in their /etc/ssh/ssh_config files but that did not fix the problem from the Linux hosts to FreeBSD. I believe it is because of the way that OpenSSH was compiled on FreeBSD but I am not certain. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

If don't you need to fix this with XAuthLocation in your sshd_config file on the Linux box I tried that and it did not solve the problem, but you gave me an idea and it worked. I put 'XAuthLocation pathto_xauth' in my ~/.ssh/config on the FreeBSD box and that fixed the problem for both Linux boxes; I can connect to either of them and run X apps. I believe that if I do the same thing on each of the Linux boxes, I should be able to connect to the FreeBSD host and run X apps. Also, instead of each user having to do the above modification, I will put 'XAuthLocation' in /etc/ssh/ssh_config (instead of sshd_config) globally and that should take care of this issue. thank you for your help ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I think you need to generate a new cookie with $ xauth generate :0 . trusted See xauth(1) for more info.

Typical usage: xauth add :0 . 'mcookie' Therefore, you should be able to use any random 128-bit hex number instead of mcookie. I'm not sure how secure it would be, but it should work just fine.

X11 forwarding problems in FreeBSD 6.2
