Nfs which port firewall

I didn't see the port with the grep nfs , but I left off the grep to learn that is for portmapper.

Also good to know! KennyYounger rpcinfo is a useful too. If this answered your question, don't forget to mark it as the answer for the benefit of future viewers.

You need mountd open when you first mount the filesystem. It runs on a dynamic port, so it won't always be the same.

I put a link to a guide in my answer. Thanks bonsaiviking. Critical info for this process. I upvoted your answer! Could you give a brief description of what those services "cluster and client status", "NFS lock manager" do and when they might be needed? If those services are blocked by a firewall, will NFS servers and clients degrade gracefully, or just lock waiting for a response?

With respect to mountd, life is a lot easier if you reconfigure to ensure the mountd port is fixed. Network File Sharing NFS is a protocol that allows us to share directories and files with other Linux clients over a network. The ports for NFS are confusing for many people.

We will deep dive into this today. NFSv3 Port. NFSv4 Port. The portmapper service is consulted to get the port numbers for services used with NFSv3 or NFSv2 protocols such as mountd, statd, and nlm etc. NFSv4 does not require the portmapper service. The ports for other NFS services like mounted, nlockmgr, status are product-dependent. These are two different products for NetApp company. We can see that the ports for portmapper and nfsd are the same. Upgrade using the Operator. Upgrade using the Daemonset.
