Share a folder on Ubuntu via NFS

First post on the zen of linux. A good start would be a basic post about how to get multiple machines working on a shared folder.

The way to go in the linux/unix world is to use the pretty stable and reliable NFS filesystem.

At first, you have to select a machine you would like to make the "server". Open a console window and type

sudo aptitude install nfs-user-server

then configure it (you'll need to use sudo to edit these):
edit the /etc/exports file add this line:
/home/<name of dir to export/share> <ip of other machine/the client>(rw)
edit the /etc/hosts.allow file add this line
ALL:<ip of client machine>
edit the /etc/hosts.deny file add this line:
finally, on this machine (the server) restart nfs with:
sudo /etc/init.d/nfs-user-server restart
(alternatively use: sudo /etc/init.d/nfs-common restart - if we would use the common-server)
Now beginn to add the client machines:

First you need to create a pseudo-directory, a mount-point for the remote folder
cd /home
sudo mkdir shared

then change permissions for this dir
sudo chown root:users /home/shared
sudo chmod 777 /home/shared

edit the /etc/fstab file on the client machine to mount on boot:
sudo gedit /etc/fstab
add this line in /etc/fstab<server IP>:/home/shared/ /home/shared nfs defaults 0 0

(alternatively:)<server IP>:/home/shared /home/shared nfs rsize=8192,wsize=8192,timeo=14,intr

then go and update the mounts for this session (without rebooting):
sudo mount -a
