NFS Interview Questions & Answers part 3
Q: – What is NFS ?
NFS stands for Network File System. NFS was originally developed by Sun Microsystems in the 1980's. NFS allows remote hosts to mount file systems over a network and interact with those file systems as though they are mounted locally. This enables system administrators to consolidate resources onto centralized servers on the network.
Q: – Which NFS versions are available ?
NFS Version 2
NFS Version 3
NFS Version 4
For every mount request received from an NFS client, rpc.mountd adds an entry to the /var/lib/nfs/rmtab file. When receiving an unmount request, that entry is removed.
The portmapper keeps a list of what services are running on what ports. This list is used by a connecting machine to see what ports it wants to talk to access certain services.
