NFS (Network File System) Client
The Network File System (NFS) is used to mount a disk partition on a remote machine (as if it were on a local
hard drive), allowing fast, seamless sharing of files across a network. NFS allows users to develop applications
for the V2403-LX without worrying about the amount of disk space that will be available. The V2403-LX only
supports NFS client protocol.
ATTENTION

The following procedures illustrate how to mount a remote NFS Server.
1. Scan the NFS Server’s shared directory:
#showmount –e HOST
showmount: Shows the mount information of an NFS Server
-e: Shows the NFS Server’s export list.
HOST: IP address or DNS address
