Share files through NFS protocol under Linux
An easy way to share files trough a network between Linux machines is using the NFS (Network File System) protocol.
You only need to know the IP address of the network computers and to install the NFS server/client into each computer.
Like others server-client systems, one computer will be the server (which will share the files) and the others will be the clients (whose will connect to the shared files.
The procedure to share the folder is:
Install the NFS server in the A computer:
Configure the folders in A that will be shared through the network. Add the next line to the "/etc/exports" file (shared folders with permissions, one per line):
Start NFS configuration:
Install the NFS client:
Mount the remote shared folder into the local machine:
If we want to add it permanently into the init mount table, add the next line into the "/etc/fstab" file:

Files server:
The A computer with the IP address 192.168.1.4 want to share the folder "/home/user/Public" over the network for everyone that want to connect.The procedure to share the folder is:
Install the NFS server in the A computer:
# apt-get install nfs-kernel-server portmap
/home/user/Public 192.168.1.4/255.255.255.0(rw,sync,subtree_check)
# /etc/init.d/nfs-kernel-server restart
Client for the file server:
Now we want connect the B computer to the shared folder and mount it under the local folder "/home/user2/PublicB" (In the B machine the folder must be previously created).Install the NFS client:
# apt-get install nfs-common
# mount -t nfs 192.168.1.4:/home/user/Public /home/user2/PublicB
If we want to add it permanently into the init mount table, add the next line into the "/etc/fstab" file:
192.168.1.4:/home/user/Public /home/user2/PublicB nfs defaults 0 0
