By default, the NFS daemon is already configured to run a static port of 2049. The port is true on both TCP and UDP protocols.
Is NFS UDP or TCP?
The default transport protocol for NFS is TCP; however, the Fedora kernel includes support for NFS over UDP. To use NFS over UDP, include the mount option -o udp when mounting the NFS-exported file system on the client system.
What ports does NFS v4 use?
NFSv4 uses a single port number by mandating the server will listen on port 2049. There are no “auxiliary” protocols like statd, lockd and mountd required (but see the section Mounts and automounter below), as the mounting and locking protocols have been incorporated into the NFSv4 protocol.
How do I allow NFS through firewall?
To configure a firewall to allow NFS, perform the following steps:
- Allow TCP and UDP port 2049 for NFS.
- Allow TCP and UDP port 111 ( rpcbind / sunrpc ).
- Allow the TCP and UDP port specified with MOUNTD_PORT=” port “
- Allow the TCP and UDP port specified with STATD_PORT=” port “
What protocol does NFS use?
All versions of NFS can use Transmission Control Protocol (TCP) running over an IP network, with NFSv4 requiring it. NFSv2 and NFSv3 can use the User Datagram Protocol (UDP) running over an IP network to provide a stateless network connection between the client and server.
What is port 111 used for?
Port 111 is generally called an unsecured or a security vulnerability as it provides direct and easy access to the RPC services. Port 111 is used in Unix, Linux, and related operating systems to list ports and related RPC services where an attacker can bet detailed information to abuse these services and ports.
Is NFS a file system?
What is Network File System (NFS) Network File System (NFS), was a protocol invented in the 80’s to facilitate remote file sharing between servers. There are multiple versions of NFS. NFS v3 is the most common.
Which is better SMB or NFS?
NFS offers better performance and is unbeatable if the files are medium-sized or small. For larger files, the timings of both methods are almost the same. In the case of sequential read, the performance of NFS and SMB are almost the same when using plain text. However, with encryption, NFS is better than SMB.
How do I connect to NFS?

What is the difference between NAS and NFS?
Network Attached Storage (NAS) is a device that allows users to access files through a network. It allows users to access and share files from their individual stations through a central server. NFS (Network File System) is a protocol that is used to serve and share files on a network.
Is NFS still used?
The most common NFS in use today, NFSv3, is 18 years old — and it’s still widely used the world over.
Is NFS safe?
NFS itself is not generally considered secure – using the kerberos option as @matt suggests is one option, but your best bet if you have to use NFS is to use a secure VPN and run NFS over that – this way you at least protect the insecure filesystem from the Internet – ofcourse if someone breaches your VPN you’re …
