Examples (2) from the manual page, untested
% xauth extract - $DISPLAY | ssh otherhost xauth merge -
The most common use for xauth is to extract the entry for the current display, copy it to another machine, and merge it into the user's authority file on the remote machine:% xauth generate :0 .
The following command contacts the server :0 to create an authorization using the MIT-MAGIC-COOKIE-1 protocol.
