Greetings,
This is an old 233MHZ "box1" or 192.168.1.1 set to be the client. It is
connected to another 1GHZ "box2" or 192.168.1.2 via a crossover cable. As
you can see I am able to ping the client from the client (no big
excitement there), and I am able to ping the server (after much
experimentation and research). (Don't ask me ALL the things I did wrong
and the BIOS setting when there two NIC's installed --- whew!!!)
Now I am trying to set up a NFS to gain access of files from either box. I
am unable to mount the file system for use in either direction. I've read
every "HOW-TO" and believe I've got it set up right, but I'm stuck. Both
systems are versions of RedHat (7.3 for the older and 8.0 for the newer
box).
Anything I should check, do or change? I'm fairly new to Linux so I may
have done something basically wrong.
Cheers,
Bob Stelmack
