Do the following from client and
let me know the result:

1. ping
if not working ping .

2.showmount -e : should show all nfs exported file systems.

3. rpcinfo -p : ensure nfs,rpcbind,status,nlockmgr,llockmgr and mountd process are displayed

Which linux you are using ?(red hat, suse...)
What is the linux kernel version?

Hi

Here Iam having redhat 9 alo my doubt is it should show an output showmount -s irrespectice of
clients

Thanks
Binu

On the nfs server do:
showmount -e and verify the filesystems are exported.

Try these:
1.Put Client name in /etc/hosts of nfs server. ping to client from server and ensure the connectivity. Try NFS mount from client.

2.I remember that by default firewall is enabled in linux. Try showmount after disabling firewall. Probably the command is:

service iptables stop

Hi Sudeesh

1)showmount -e shows RPC tme out in the server

2)The clinet pinging from the server side
3)If we give an NFS mount
RPC time out error is coming


Thanks

If showmount is failing on the server it self, it points to NFS server process issue.

o/p from working server
#showmount -e
no exported file systems for rx260-09
#rpcinfo -u rx260-09 mountd
program 100005 version 1 ready and waiting
rpcinfo: RPC: Program/version mismatch; low version = 1, high version = 3
program 100005 version 2 is not available
program 100005 version 3 ready and waiting


Try the following on nfs server:
rpcinfo -u mountd
if this fails do
/usr/bin/ps -ef | /usr/bin/grep mountd
/usr/bin/kill PID
/usr/sbin/rpc.mount

Can you pls paste the o/p from /etc/exports.

did u try disabling the firewall?

Its time to go....
Let me try to set you in the right path before logging off.

At this point I think the issue is with your NFS server.

1. Check /etc/rc.config.d/nfsconf and ensure
NFS_SERVER=1
START_MOUNTD=1

2. Check /etc/inetd.conf, if rpc.mountd is enabled disable it. If rpc.mountd is enabled here, will create issues.

3. Reboot your nfs server.

4. Once server is up do
rpcinfo -p : check all the process started.
rpcinfo -u mountd
showmount -e

if this goes well, try mounting from the client.

Best of luck
