Hi Ferdinand,

It is fairly easy to filter on CIFS traffic only - simply use a filter of "smb".

This will filter on only packets which Ethereal has determined to be CIFS-related, including TCP ACK-only frames, etc.

It WON'T filter on traffic that may related to CIFS but not CIFS itself, such as WINS, NetBIOS name service, DNS, MS-Kerberos, LDAP, etc., however, building filters for these is also fairly easy, and you can add statements together. See the Ethereal User's Guide (section http://www.ethereal.com/docs/user-guide/ch03dispfilt.html) for details on how to do this.

If you're looking to filter on specific CIFS commands or other fields, take a look at the Ethereal man page for the smb.* fields.

Hi all,

i try to analyze a cifs trace.

Please, how can i set a special filter for cifs requests, responses,
close etc.
I know the filter expressions for tcp.ports, http.* and all the other
normal network traffic, but CIFS seems to be a protocol with a big
overhead and and a lot of undocumented procedures.

thx in advance
Ferdinand
