Are you logged in to the set top box when running the mount command? You mount directories, not files as you indicated. Also are the ports for nfsd and the portmapper blocked in either the Linux VM or the Windows host?

I think you meant terminal emulater instead of serial emulater.

Check your logs in /var/logs/. Look at messages and files in the /var/log/nfs/ directory if it exists.

NFS3 uses separate ports for file transfer and for control. Use netstat to see which ports are open. Compare with the firewall ports.

Make sure the uid's match for your user in the VM and the settop box. Post the /etc/exports file. What security mode are you using?
This will be listed after the sec= option in /etc/exports. If this option isn't used, sec=sys is the default. The error message sounds more like an authentication or networking issue than an nfs issue.

/etc/exports looks like this
/opt/nfsroot_uclibc *(rw,no_root_squash,no_all_squash)
/opt/refsw *(rw,no_root_squash,no_all_squash)

------------------------------------

there is no file as /var/log/nfs
i have checked the logs but unable to gather any information.
which ip address should i use while using the mount command...linux ip /windows ip
how do i create /mnt/nfs on set top using teraterm ??

please reply!!!!

I think you missed the point here.
NFS uses alot of different ports: 111, 2049,(these 2 are very common) ... and after that some ports that are randomly choosen.
If you want this to work properly you have to set the range of ports that can be used.
What I would do first in your case is disable the firewall(as you seem to lack some knowledge on nfs (no offense)).

Then test again.
See what you can find in any log files.

Do you have any messages in the log files on the nfs server?

There are other files in /var/log I would think: /var/log/messages...

The IP depends on if your virtual is in bridged mode or not and on another network or not.
