I am created an NFS share on a Desktop(Ubuntu 10.10 64 bit)
which has a USB hard disk attached.
Started the NFS Kernel Daemon and entered the directory name in /etc/exports
the directory exists.
On the client machine which is Ubuntu 10.04 server edition when I
tried to mount the share
mount -t nfs IP:/path/to/share /mnt/local
got following error
mount: wrong fs type, bad option, bad superblock on IP:/path/to/share
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so


when I checked rpcinfo -p

then got following error

rpcinfo: can't contact portmapper: RPC: Remote system error - Connection refused

what else do I need to do?

Did you start the portmapper?

Suggests portmapper not running or firewalled.

Right it was not running.
That rpcino error went when on client machine I installed nfs-common
and portmap.

On the server machine I did
showmount -e
Export list for tapas:
/media/USB <IP of machine which is allowed>

there was no directory which it should show me otherwise.

also on client machine mount -t nfs <location on lan> <local>
is failing.
Here is strace log

This error of portmapper is resolved.
I had forgotten to install portmap.
