Not precisely sure what the problem is but the url points to the Gentoo forum where someone seems to have shown a bug in nfs-utils. I think the problem is that udp detection not working in nfs-utils-1.1.6 I was told it was a known bug but I couldn't find it reported previously and so I've logged it, if it is fixed already I apologise. Reproducible: Always Steps to Reproduce: 1.Install nfs-utils 2.Try to connect to cheap crap 35HD-DUAL-NAS server via nfs 3. Actual Results: response is this mount -v -t nfs 192.168.0.9:/mnt/ide3/fred /home/fred/nfs mount.nfs: timeout set for Sun May 17 18:11:12 2009 mount.nfs: text-based options: 'addr=192.168.0.9' mount.nfs: mount(2): Operation not supported mount.nfs: an incorrect mount option was specified Expected Results: Should have mounted fs Does work if you specify udp mount -v -o proto=udp -t nfs 192.168.0.9:/mnt/ide3/fred /home/fred/nfs
