How does NFS work?

NFS is the most common protocol for sharing files between Unix systems over a network. NFS servers export directories from their local hard disks to NFS clients, which mount them so that they can be accessed like any other directory.
How many NFS connections are there?
The default value is 20. Because each NFS client that uses TCP uses a single connection with the NFS server, each client can use a maximum of 20 concurrent threads on the server. All NFS clients that use UDP share a single connection with the NFS server.
What port is NFS?
NFS uses port 2049. NFSv3 and NFSv2 use the portmapper service on TCP or UDP port 111. The portmapper service is consulted to get the port numbers for services used with NFSv3 or NFSv2 protocols such as mountd, statd, and nlm.
What is the default port of NFS server?
Port 111 (TCP and UDP) and 2049 (TCP and UDP) for the NFS server. There are also ports for Cluster and client status (Port 1110 TCP for the former, and 1110 UDP for the latter) as well as a port for the NFS lock manager (Port 4045 TCP and UDP).
