NFS - Ports used by

[Michele (Mike) Alberton]

Hi Folks !

We're trying to use NFS on an HP-UX 11.0 J7000 to remotely mount some filesystem out of an HP-UX 11.00 N4000.
Due to the network layout, we have a lot of firewalls in between (plus some reverse proxies and so on). We're able at the moment to connect the two systems through a telnet (since we asked the network administrator to open port 23). Now what about NFS ?
I mean is there a predefined set of ports used by NFS to mount the filesystems ? We cannot open entirely the network so that we would like to know if this the way it works or not.
Thanks !

Mike

search for nfs in /etc/services

Try 'grep nfs /etc/services', and 'netstat -a |grep nfs'.

This is an example of the services for a Service Guard Cluster,..

nfsd-keepalive 1110/udp # Client status info
nfsd-status 1110/tcp # Cluster status info
nfsd 2049/udp # NFS remote file system
nfsd 2049/tcp # NFS remote file system

Hope this helps! Share and Enjoy! Ian

Hi Mike,

in /etc/services you can find predifined ports for nfs:

nfsd-keepalive 1110/udp
nfsd-status 1110/tcp
nfsd 2049/udp


Allways stay on the bright side of life!

See the file /etc/rpc for some more ports related with NFS services.

see the man page of the command rpcinfo too.

Hello,

one problem might be that some firewall guys only think in "tcp" if you ask for a port permission. For NFS you need to permit UDP!
