Portmap The primary daemon upon which all the RPC rely

• Manages connections for applications that use the RPC specification

• Listens to TCP port 111 for initial connection

• Negotiate a range of TCP ports, usually above port 1024, for further comms.

You need to run portmap on both the NFS server and client.

• Nfs (rpc.nfsd)
  • Starts the RPC processes needed to serve shared NFS file systems
  • Listens to TCP or UDP port 2049 (port can vary)
  • The NFS daemon needs to be run on the NFS server only.

The nfslock daemon needs to be run on the NFS client only.

Nfslock (rpc.mountd)

• Used to allow NFS clients to lock files on the server via RPC processes.

• Negotiated port UDP/TCP port

• The nfslock daemon needs to be run on both the NFS server and client

netfs

• Allows RPC processes run on NFS clients to mount NFS filesystems on the server.
