Hi Gaurav
I was done following trouble shooting related to NFS
rpcinfo -p 192.168.0.200
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100024    1   udp   1024  status
    100024    1   tcp   1025  status
this is on my server where 192.168.0.200 is my client
But when i run linux terminal server project on client machine it gives my following error
RPC mount failure
Not mounted /opt/ltsp:192.168.0.199 on /mnt/ of client machine
Reason given by server Permission Denied
Please if you have any solution help

[deven_01]

when i give following cmd on server it gives me following error   
[root@ws199 root]#showmount 192.168.0.200
mount clntudp_create: RPC: Program not registered

Hi TO ALL,
DO ONE THING ,  TRY THIS IN ALL OF YOUR MACHINES, THEN TELL WHEATHER THIS RUNS OR NOT.
Suppose u want to share /home dir of ur m/c then
open /etc/exports file
/home 192.168.2.180(rw)

save this file
  restart the services as:
#service portmap restart
#service nfs  restart
 After that go to ur client (ip-192.168.2.180)
give following command there as
#mount 192.168.2.182:/home /mnt

{ where 192.168.2.182 is ip-address of ur NFS server}
after that go to /mnt directory of client -mc

& check  its contents

it willl work definitly
Enjoy
