NFS Server

If you have two or more machines, you may wish to share disk space or devices, such as a CD drive, between machines. For this there is network file system (NFS), the easiest way of sharing files and resources across a network.


NFS is the way of working with files on a remote machine as if they are on your local one. NFS is the standard de facto solution to access the same $HOME directories from any machine on the Net. Using it also is a good way to avoid keeping duplicated informatioNFS n from eating large amounts of disk space.
