This file is on the server and lists the IP numbers of other computers 
(clients) which are allowed to access the server.  The client is 
192.168.1.2 not 1.1 so 1.2 should be in exports..  I had tried adding the 
second IP number after permission was denied but apparently that is too 
late.  I can change to ro if I only want to copy not modify files on the 
server.

Worked well in BL3 too.

1.2 was not listed in exports on the server.

(Probably for some other version of NFS - we seem to have 2.2beta47)

Steven, thanks for this simplified setup.  The HOWTO was much too 
complicated to figure out and it also assumed you had a standard linux 
with everything set up ready to use.

We now have a whole-house network plugged into a hub which connected (via 
a router) to the DSL modem and the internet.  Is the above sufficiently 
secure?  Should I also have hosts.allow and hosts.deny?
