I have installed nfs-kernel-server on my ubuntu machine.
i exported a dir using exports file
sudo vim /etc/exports
/home/comp1/nfs_dir *(rw,sync,no_root_squash)

if i give exportfs command i can see the exported directory

On client side:
I created a directory in home folder called mou_nfs
i tried to mount exported dir into it using
sudo mount 192.168.1.100:/nfs_dir /home/comp2/mou_nfs
but i get error as
mount: 192.168.1.100:/nfs_dir failed, reason given by server: Permission denied

even i tried mounting using
sudo mount -t nfs 192.168.1.100:/nfs_dir /home/comp2/mou_nfs

But same error is there


can someone help me in this??

what are the permissions for nfs_dir? did you try giving 777 ?

Shouldn't you use

I tried both the ways you suggested..
permission to nfs_dir is 777
& i have also tried with full path already..

already tried with this..
its not working

Problem got solved!!!!!!!!!!!!

Just needed to install a package called 'nfsboot' on server..

Does that mean the NFS wasn't actually running?

nfs-kernel-server was running

but, client was not allowed to connect to server..

'nfsboot' says:
Allow clients to boot over the network
This package help you to set up your host to allow clients to
boot over nfs.

This package should be installed on the server so that the clients
can connect to it. The package contains no server itself, but recommends
all packages that you will need in order to make nfsrooted clients
to work.

after installing this permission problem was solved..
