NFS server not registering with portmap or rpcbind on Linux

[pjaromin]

I'm pulling my hair out trying to get the NFS server working. I have a maven development environment and stand alone installations on both Linux Mint 13 and Centos 6.2. I've been working with community 4.0.b and 4.0.d, starting as an unprivileged use and as root. No joy.

I've also shut down portmap (Linux Mint) and rpcbind (CentOS) and tried using the built-in port mapper, different ports, etc.

I can telnet to 2049 every time, however it never registers with a portmapper service and consequently mount.nfs fails.

With 'showmount -e' -> RPC: Program not registered.

When I attempt:
mount.nfs -v -o nolock localhost:/alfresco /mnt/alfresco
mount.nfs: mount(2): Protocol not supported
…
mount.nfs portmap query retrying: RPC: Program not registered.

I'm not seeing much discussion here other than more complex setups with native + alfresco NFS, alternative ports, etc. Which leads me to believe that I'm overlooking something simple. However at this point I don't know how to further troubleshoot this issue.

Any advice?

Thanks!

Additional info…..

I've just noticed that before starting Alfresco, I get "connection refused" messages from mount.nfs

mount.nfs: trying text-based options 'vers=4,addr=127.0.0.1,clientaddr=127.0.0.1'
mount.nfs: mount(2): Connection refused
mount.nfs: trying text-based options 'vers=4,addr=::1,clientaddr=::1'
mount.nfs: mount(2): Connection refused
mount.nfs: trying text-based options 'vers=4,addr=127.0.0.1,clientaddr=127.0.0.1'
mount.nfs: mount(2): Connection refused
mount.nfs: trying text-based options 'vers=4,addr=::1,clientaddr=::1'
mount.nfs: mount(2): Connection refused
mount.nfs: trying text-based options 'vers=4,addr=127.0.0.1,clientaddr=127.0.0.1'

But as/after alfresco starts up, the message changes….

mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: portmap query retrying: RPC: Program not registered
mount.nfs: prog 100003, trying vers=3, prot=17
mount.nfs: portmap query failed: RPC: Program not registered
mount.nfs: prog 100003, trying vers=2, prot=6
mount.nfs: portmap query retrying: RPC: Program not registered
mount.nfs: prog 100003, trying vers=2, prot=17
mount.nfs: portmap query failed: RPC: Program not registered

So clearly there's something else happening here.
