Turn on verbose flags when you ssh and see if it's complaining about missing 
xauth..  (ssh -v -v user at box.com). make sure xauth is in your path too, or at 
least that SSH knows where it is (You can specify in your sshd_config)

Alternatively, if you aren't doing X11 forwarding, you can disable it by 
removin it from your config file or when you ssh do ssh -x user at box.com
