What port does NFS client use?
port 2049
Network File System (NFS) is used by UNIX clients for file access. NFS uses port 2049. NFSv3 and NFSv2 use the portmapper service on TCP or UDP port 111.
Is portmap required for NFS client?
All versions of NFS can use Transmission Control Protocol (TCP) running over an IP network, with NFSv4 requiring it. For this reason, TCP is the preferred protocol when connecting to an NFS server. NFSv4 has no interaction with portmapper, rpc. mountd, rpc.
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 many ports does a NFS server need?
There are seven ports need to be taken care of for NFS server. rpcbind listens on TCP and UDP port 111. It is the default port number and it doesn’t require special configuration. nfsd listens on TCP and UDP port 2049. It is also the default port number and it doesn’t require special configuration. These five ports should be configured
Which is the default port number for NFSD?
nfsd listens on TCP and UDP port 2049. It is also the default port number and it doesn’t require special configuration. Fix ports for RQUOTAD_PORT, MOUNTD_PORT, LOCKD_TCPPORT, LOCKD_UDPPORT and STATD_PORT These five ports should be configured to be fixed to avoid rpcbind assign random port for it.
Which is the transport protocol supported by NFS?
TCP is the connection-oriented transport protocol that is supported by the release. UDP is the connectionless transport protocol. When both the NFS protocol version and the transport protocol are determined by negotiation, the NFS protocol version is given precedence over the transport protocol.
How does the NFS service ( system administration guide ) work?
By default, the public file handle on an NFS server is established on the root file system. This default provides WebNFS access to any clients that already have mount privileges on the server. You can change the public file handle to point to any file system by using the sharecommand.
