NetBIOS Session Service (NBSS)
The NetBIOS Session Service is part of the NetBIOS-over-TCP protocol suite, see the NetBIOS page for further information.
XXX - add a brief description of NBSS history
XXX - Add example traffic here (as plain text or Wireshark screenshot).
The NBSS dissector is fully functional.
(XXX add links to preference settings affecting how NBSS is dissected).
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 NBSS display filter fields can be found in the display filter reference
Show only the NBSS based traffic:
You cannot directly filter NBSS while capturing. However, as it runs atop TCP port 139, you can filter on that one.
Capture NBSS traffic:
tcp port 139
