OpenSUSE Network :: Mount Command Gets Stuck With No Error Message?

I am using 11.3 on one machine and 11.2 on the other (a netbook). 11.4 won't install on either and 11.3 on the netbook fails to install as well.

I am using the same setup as I have always used when both systems ran 11.2 (details below) but now I can only mount a drive in one direction. In the other direction the mount command gets stuck with no error message until it eventually times out. I can ping and ssh the machines from each other without difficulty.

Even in the direction in which the mount apparently works (11.2 mounting a drive on the 11.3 machine) when I try to copy files across nothing actually happens.

exportfs -a was run successfully on the exporting machine, and nfsserver is running on both machines as does nfs client.

The exporting machine is 192.168.1.102 (eeelinux) and the other machine is 192.168.1.101 (nina).

Details:
The /etc/exports file on the exporting machine (192.168.1.102) looks like this:
eeelinux:/home/naima # more /etc/exports
# See the exports(5) manpage for a description of the syntax of this file.
# This file contains a list of all directories that are to be exported to
# other computers via NFS (Network File System).
