Thanks for your suggestion. On my Linux system, the default path for ssh to find xauth is already /usr/bin/xauth (according to the man page). To be sure, I tried setting it explicitly but it still didn't work. I know that I can tunnel to other X servers, just not the FreeBSD one. My FreeBSD sshd_config is rather uninteresting because everything is commented out and using the defaults. For convenience's sake, here are some of the interesting lines: #UsePAM yes #AllowTcpForwarding yes #GatewayPorts no #X11Forwarding yes #X11DisplayOffset 10 #X11UseLocalhost yes #PrintMotd yes #PrintLastLog yes #TCPKeepAlive yes #UseLogin no #UsePrivilegeSeparation yes #PermitUserEnvironment no #Compression delayed #ClientAliveInterval 0 #ClientAliveCountMax 3 #UseDNS yes #PidFile /var/run/sshd.pid #MaxStartups 10 #PermitTunnel no I also tried doing it the old fashioned way and viewing the X clients over telnet, which worked fine. It's too insecure to do that from outside the local network, though.
