The Network File System (NFS) is a distributed file system that allows users to access files and directories located on remote computers and treat those files and directories as if they were local. For example, users can use operating system commands to create, remove, read, write, and set file attributes for remote files and directories.

The NFS software package includes commands and daemons for NFS, Network Information Service (NIS), and other services. Although NFS and NIS are installed together as one package, each is independent and each is configured and administered individually. See AIX Version 4.3 Network Information Services (NIS and NIS+) Guide for details on NIS and NIS+.

AIX supports the latest NFS protocol update, NFS Version 3. AIX also provides an NFS Version 2 client and server and is, therefore, backward compatible with an existing install base of NFS clients and servers.
