Progress. Killing Guarddog does allow the ping. Executing the mount
command manually (once I also start NFS manually on mandrakebox) does
mount mandrakebox /home/lee to /mepisbox /home/mandrake. Need to find
out how to permit NFS between these two with Guarddog running.
When I open /home/mandrake on my mepis laptop, however, even with all of
this done, the directory shows as empty. I should be seing my /home/lee
directory there, shouldn't I?
