Hi Rich
I have done changes that you said accordly with my machines "A" and "B" and I now can use commands like g.region and r.mapcalc but I can not start Monitors(0-6)  for visualize data. Nviz is OK and I can visualize data.
Any suggest?
My general problem is:
My machine "A" (Pentium III and 256 MB Ram and  little Hard-Disk) is more
efficient than machines "B" (Pentium MMX with 64 MB and  Big Hard Disk to
store data) so I hope to solve more fast my problems of visualization and
calculations if  Grass5 is on "A" and data to read are on "B"? I hope this
is good solution. Can you give me your opinion?

 Thanks a lot in advance
