Does the server allow X11 forwarding?

I have followed this WIKI, and still getting the error when I connect:

X11 forwarding request failed on channel 0

I just tested myself with the exact settings on the wiki, and X11 forwarding works just fine here.

Maybe a long shot, but do you have ipv6 enabled? If so, try disabling it.

Perhaps you could pastebin your /etc/ssh/sshd_config from the server, and the /etc/ssh/ssh_config from the client. Then give us the links.

Also, please add the -v switch to your ssh command and post the output.

UPDATE: Solved. I just had to uncomment: 'AddressFamily all' in sshd_config
In this case, I uncommented it, and changed it to AddressFamily inet

These exact steps worked for me as well.

Note: it should be "any", not "all" (which gives /etc/ssh/sshd_config line 14: unsupported option "all" on rc.d restart sshd)

Also, on an IPv4 Ubuntu client, setting it to "inet" fixed it here. I updated https://wiki.archlinux.org/index.php/Se … forwarding

Limiting the address family is simply useless. The only thing to verify is whether xorg-xauth is installed on the systems. The error message will go away if xorg-xauth is present. Suggestions around xhost on the wiki do not make sense, since ssh tunnels X11 from one loopback interface to another; it doesn't connect to the X-server from remote hosts.

Installing xorg-xauth as suggested is THE ONLY way to solve the problem for me!
