Hmm, it could be an ssh thing, not sure, probably an xauth thing (have a look 
at man xauth).  See if setting your IP address allows to access your parents 
machine: 

xdpyinfo -display XXX.XXX.XX.XX:0.0  <--where XXX.XXX.XX.XX is your IP address

of try to set the relevant env variable: setenv DISPLAY XXX.XXX.XXX.XXX:0 at 
your client machine first.

Alternatively, ask them to login and then use the same login credentials.

HTH.
