Hi,

NIS means that you use a (NIS-)server to share the 'hosts', 'passwd' and 'group' to all clients, so you don't have to define this for every client itself.

NFS is to share directories in a network - it's also the protocol/job/program to manage this.
So the clients see these directories as their own directories.

P.S.
If this is a linux question you should also tell which linux. Here's the linux forum:

Hi,
Both are services, but 2 different services.
Both are using RPC communications,
Both were developped by SUN
NIS, is a network information name service
you use it like we use LDAP now, to spread accounts definitions, group defs, hosts definitions, automount definitions..

NFS is network file system
So you may mount a filesystem from a server to a client. NFS can be used through the automounter.

You can for instance describe all your user account, on NIS , auto mount table too, so when a system is configured, all the users defined as beeing allowed on the system with the nis tables will be able to log on that system and have their count automounted.

- usually the trend is to use more ldap than NIS for those descriptions as NIS is not really secure. (NIS+ brings more security capabilities)

Any reason you are asking Linux questions here in HP-UX?

NFS is Network File System.
NIS is Network Information System, which includes the former YP (yellow pages) commands. It allows centralized passwords, etc.

NFS has a future, NIS doesn't :)
