what is the difference between the rpc and portmap.

[Pete Randall · Accepted solution]

I would suggest reading the man page for rpc and comparing it to the rpcbind man page.

RPC (Remote procedure call) is a model of communication used to exchange data between different processes, see
http://en.wikipedia.org/wiki/Rpc

portmapper is part of this communication, see
http://en.wikipedia.org/wiki/Portmap

[tkc]

RPC is Remote Procedure Call, a communication model.
portmap is the daemon in HP-UX 10.20 that converts rpc program numbers into port numbers. in HP-UX 11.x, it's called rpcbind.

As you can see now, asking for a difference between rpc and portmap is just like asking for the difference between an apple and an apple-tree.

The main idea behind all the interprocess communication models is this:
How to make the communication between processes (running on different systems and even operating systems) easy and reliable?

There came up a lot of solutions over the years, like rpc, NET, CORBA, Java RMI ... to make the application development easier.

thanks for replying it, but still i am not getting it.
what is role of rpc in nfs.
what is role or portmap.

[Torsten.]

I try to make it very simple:
NFS is using RPC for communication between server and clients, RPC is using the portmapper as a part of RPC.
