How does NFS work?

NFS, or Network File System, was designed in 1984 by Sun Microsystems. This distributed file system protocol allows a user on a client computer to access files over a network in the same way they would access a local storage file. Because it is an open standard, anyone can implement the protocol.

Steps. Next, run ‘netstat -an | grep 2049’ to display a list of NFS connections. Look for the connection that matches one of the NFS server IP from nfslookup. This is the NFS server IP that the client is using and will be the IP you need to use for tracing if necessary.

The Network File System (NFS) is a client/server application that lets a computer user view and optionally store and update files on a remote computer as though they were on the user’s own computer.

Which file is used in NFS client configuration?
