Port 111 (TCP and UDP) and 2049 (TCP and UDP) for the NFS server.
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 protocol is used by NFS?
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 ports does NFS v4 use?
NFSv4 runs on TCP port 2049. The NFS server must accept incoming connections on this port. Unlike previous versions of NFS, this is the only port that is required.
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 is port 111 used for?
GRC | Port Authority, for Internet Port 111. Description: This port is used as a well-defined means for determining the ports upon which other services in the system are running. It is referred to as a “portmapper” because it provides a directory, or “mapping” between available services and their ports.
Why NFS is used?
NFS is an Internet Standard, client/server protocol developed in 1984 by Sun Microsystems to support shared, originally stateless, (file) data access to LAN-attached network storage. As such, NFS enables a client to view, store, and update files on a remote computer as if they were locally stored.
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.
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.
What is NFS vs SMB?
NFS is used for server to server file sharing and is mostly a server-client file-sharing protocol. SMB is used for the transfer of files from the places the user needs and is mostly a user client file-sharing protocol. NFS requires AppleDouble files to share Apple extended documents.
How do I connect to NFS?
Click “Programs and Features” from the list of available options, then click the “Turn Windows features on or off” link in the left panel. Click the “Services for NFS” link in the list of available Windows features to install the service.
What is Samba port number?
SMB has always been a network file sharing protocol. As such, SMB requires network ports on a computer or server to enable communication to other systems. SMB uses either IP port 139 or 445.
Network File Sharing (NFS) is a protocol that allows you to share directories and files with other Linux clients over a network. … An NFS file share is mounted on a client machine, making it available just like folders the user created locally.
What port is Mountd?
|UDP||611||NFS mount daemon ( mountd )|
|TCP||612||NFS mount daemon ( mountd )|
|UDP||613||NFS status daemon ( statd , statmon )|
|TCP||614||NFS status daemon ( statd , statmon )|
|UDP||615||NFS lock manager ( lockd , nlockmgr )|
Use the following procedure to automatically mount an NFS share on Linux systems:
- Set up a mount point for the remote NFS share: sudo mkdir /var/backups.
- Open the /etc/fstab file with your text editor : sudo nano /etc/fstab. …
- Run the mount command in one of the following forms to mount the NFS share:
Is NFS secure?
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 …
