Uploading problem in OSK5912

Fri Dec 9 06:59:32 CST 2005

Hi Nishanth,

              I tried to mount the nfs between two linux machines with
  "mount -t nfs <serverpath>:<mntpath> -o.............as you mentioned with
server ip and export path.But could not able to mount the file system.I m
getting the error stated as *RPC:timed* *out*.Please provide a solution as
we got struck with this particular step.

Thanks and regards,
B.Nagarajan,
SANDS.
