Steve,
Wireshark is unable to reassemble these packets it
seems. If you disable "Allow subdissector to reassemble TCP streams" in the tcp
protocol preferences, the HTTP-401 is indeed shown. This allows you to
filter on http or http.response.code==401 as a workaround.
Could you file this as a bug on http://bugzilla.wireshark.org,
mentioning that http-reassembly does not work correctly in this case and attach
the tracefile to the bug?
Thanks, Cheers,
Sake

Filter for 401 response
Hi Sake. Yes, I can see HTTP/1.1 200 OK messages for example.
The attached capture file contains the 401. All boxes are checked for HTTP
preferences with Alternate TCP port = 0; all boxes checked for TCP except Try
heuristic sub-dissector first.
Thanks,
Steve

Hi Steve,
Does it show other http responses as HTTP? If so, could you send in a little
capture file (just the tcp stream containing the 401) that shows this
behaviour? If not, what are your settings in the tcp and http protocol
preferences?
Cheers,
Sake

Subject: [Wireshark-users] HTTP Filter for 401 response
I have version 0.99.6a installed on WinXpSP2. The default installation of
wireshark does not display the HTTP 401 Authorization Required using the
HTTP filter; it is labeled TCP. Do I need to change a preference or some
other setting so that HTTP filter includes the 401?
Thanks,
Steve
