I had the same problem. The C compiler from IBM would only install from real media, so for the remote sites I had to share the drive. Much gnashing of teeth eventually lead me todo the following:-
Start the mountd deamon on both client & serverStart the nfsd deamon on both client & serverMount the cd on the server with:-- mount -v cdrfs -o ro /dev/cd0 /mnt
Share the cd from the server with:-Mount the cd from the remote client with:-- mount -o ro server:/mnt /mnt
I hope that this helps.
You will, of course, have to ensure that firewall rules permit the access and remember the performance of the CD will be relatively poor, however if there is a specific need or performance is not an issue, have a bash.
