The X server on given host has a list of hosts that are allowed to
make connections to it. The list is in file `/etc/X?.hosts', where `?'
is a digit representing the display number (usually zero, therefore). 
You can also temporarily add to this list using the `xhost' program. 
Without an entry `myb' in mya's /etc/X0.hosts file, you will get the
error as reported.
