It looks like NFS is the same as Samba (network share program).
I did try the Samba. I had my home directory shared on my first PC. I succefully mounted it in place of where my home directory is on a second pc.
Everything looked fine. When I logged in, it used files in my home directory on the other PC. But when I logged into KDE, it gave me some kind of DCOPserver error. It was looking for a file .DCOPserver_ringo_:0 when in my home directory it was .DCOPserver_stinger_:0
ringo and stinger are my 2 PC names.
There must be some software that handles the whole roaming idea rather than just a shared directory?
Or am I missing something?
Ringo..............
P.S. Not worried about security. Nothing important there
