I'm trying to get Xforwarding working in Ubuntu... On the server I have uncommented the following lines of /etc/ssh/sshd_config:

X11Forwarding yes
AllowTcpForwarding yes

Now I try to ssh in, but I get the following error messages (and Xforwarding isn't working).

$ssh -Y example.com
/usr/bin/xauth:  /home/dan/.Xauthority not writable, changes will be ignored

$ssh -X example.com
/usr/bin/xauth:  error in locking authority file /home/dan/.Xauthority

Any suggestions?

Thanks
