Network File System (NFS)
XXX - add a brief NFS description here
XXX - add a brief description of NFS history
ONC-RPC: NFS uses ONC-RPC as its transport protocol. It is one of the two ONC-RPC protocols that have a port number assigned to it. The well known port number for NFS is 2049, although specialized NFS servers might use a different port.
XXX - Add example traffic here (as plain text or Wireshark screenshot).
The NFS dissector is (fully functional, partially functional, not existing, ... whatever the current state is). Also add info of additional Wireshark features where appropriate, like special statistics of this protocol.
Example capture file
XXX - Add a simple example capture file to the SampleCaptures page and link from here. Keep it short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
A complete list of NFS display filter fields can be found in the display filter reference
Show only the NFS traffic:
You cannot directly filter NFS while capturing. However, if you know the port used (see above), you can filter on that one.
Capture NFS traffic over the default port (2049):
