Will do. Thanks for the speedy response and workaround.

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

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

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
