Entering a command of the form: $ mount host:/directory /mnt/tst gives the error: mount: RPC: Unable to receive; errno = Connection refused NFS mounts from other Linux, *BSD and Digital Unix servers works fine. Investigation is hampered by not having a source rpm that matches the distributed binary: $ rpm -q -f /bin/mount mount-2.10k-1 whereas the source rpm is: mount-2.10f-1.src.rpm A 'mount' program built from the above source rpm does work. A comparison of the 'strings' output from the distributed '/bin/mount' and the one built from source shows considerable difference. I thought the GPL required that source be distributed, or available?
Red Hat Linux 6.2 shipped with mount-2.10f, not 2.10k. Are you sure you didn't get that mount RPM from rawhide, or someplace similar?
