If you filter string is "smb2", "dns", the reason the filter works is there is a field added to the tree with that name (typically the proto_id). There is no "col.proto == smb2" filter. Many dissectors have the proto id as the first field in their tree and that allows the filterability. -----Original Message----- From: Richard Sharpe <[email protected]> To: Developer support list for Wireshark <[email protected]> Sent: Sat, Jul 1, 2017 5:02 pm Subject: Re: [Wireshark-dev] Using col_set_str(pinfo->cinfo, COL_PROTOCOL, "some_string") but cannot filter on some_string
