NFS (Network File System)
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 UC-8100 series, without worrying about the amount of disk space that will be available. UC-8100 series
supports NFS protocol for client.
NFS has been installed but disabled by default. Check the following table for details.
Enable nfs manually sudo /etc/init.d/nfs-common start
sudo /etc/init.d/nfs-kernel-server start
sudo /etc/init.d/rpcbind start
Disable nfs manually sudo /etc/init.d/nfs-common stop
sudo /etc/init.d/nfs-kernel-server stop
sudo /etc/init.d/rpcbind stop
Enable nfs insserv -d nfs-common
insserv -d nfs-kernel-server
insserv -d /etc/init.d/rpcbind
Disable nfs insserv -r nfs-common
insserv -r nfs-kernel-server
insserv -r /etc/init.d/rpcbind
