Hi! I need some help regarding setting up an NFS system.
I already have machines A and B, running Red Hat 7.1, and sharing filesystems.

When I want to add machine C, running Red Hat 9, I have problems:

a) If I want to share a disk from machine C to machine A, I get:

[root@machineA]# mount /Cdisk
mount: RPC: Unable to receive; errno = Connection refused

( machine A is in machine C's hosts.allow; /Cdisk is in A's /etc/fstab; it is in C's /etc/export; the export file has been re-read using /usr/sbin/exporfs -ra; and I get the same error regardless of whether the processes:
rpc.rquotad
rpc.mountd
nfsd
are running on C or not - checked with ps -A )

b) If I want to share a disk from machine A to machine C, I get:

mount: RPC: Timed out
or
mount: RPC: Program not registered

(All the setup is supposed to be correct as before, the same disk is shared to machine B without problems in exactly the same way...)
Actually, I can't reproduce the error , yesterday I got one and today the other, and I am not aware of any change...

Thank you in advance,

MEM
