Earlier in the thread, someone mentioned doing a packet capture using
tcpdump, and I'll add the Windows equivalent, Windump, just in case. I'm
surprised that the thread has continued this long without anyone doing
exactly that, since NNTP on port 119 is clear text. It seems that a packet
cap would remove all doubt and simply settle things once and for all.

As an old instructor used to say many years ago, packets don't lie.

This is what Wireshark with its included copy
of WinPCAP is for. And yes, I have captured transactions
to News servers with it - every time the server
stops working :-) And port 119 is the only port
that makes sense, as it's plaintext and easily
readable. Even the summary window tells a tail,
and the process is not hard to follow.

Wireshark is multi-platform, so some details
underneath will change from one platform to
another. On MacOSX, only certain versions of
Wireshark, work with each version of MacOSX,
and the web site doesn't map it out for you.
Leaving you with a horrendous testing task.
On an OS with a working Repository, it should
be easier to get working materials.

Personally, I prefer tcpdump on Linux because it's what I regularly use as
part of my job, but I otherwise agree with you. I use tcpdump for captures
and Wireshark if I need to do detailed analysis of a capture.

And yes, I have captured transactions
to News servers with it - every time the server
stops working :-) And port 119 is the only port
that makes sense, as it's plaintext and easily
readable. Even the summary window tells a tail,
and the process is not hard to follow.


Many of the commercial NSPs offer plaintext access on a handful of ports,
typically to get around corporate firewalls and proxy servers, but the NSPs
I've seen discussed in this thread probably only offer that access on port
119. That should be enough to see what's going on.

I hadn't known it existed as I'm not a computer geek.
So I only know what someone suggests.

Googling, you'd never find this type of advice.
Unless you knew EXACTLY the precise keywords, as typing Usenet and nntp and
headers, etc., get you nothing in the area.

Is this the primary Windump site?
Is there a lot of impossible overhead, like there was with openssh?

I had already downloaded WinPCap and WinDump and I was working on
downloading the WinPcap-recommended Riverbed airpcap for Microsoft Windows.
http://www.riverbed.com/hk/products/...d-airpcap.html

The problem, as a novice, is if people don't say, there are always a
billion gotchas (like having to compile tcpdump and needing the pcap
program).

There is always the additional gotcha, especially with Windows, that you
end up with the "wrong" (sneaky) version which is filled with adware and
such.

So it always helps to confirm that the "canonical" site is being used.

It seems RIVERBED is the replacement for WIRESHARK based on the fact that
wireshark isn't mentioned on the WinDump site but Riverbed has its own
link.

Is that a correct assumption?

Or should I forgoe Riverbed in favor of Wireshark?

Thank you for adding value to the technical problem set!
I also try to add value in every one of my posts so that all can benefit.

The only ports I know of are 119 and 563 SSL in the free no-registration
Usenet news servers available to the public.
1. news.dizum.net:119 blank/blank (read only)
2. news.mixmin.net:563[SSL] blank/blank (read/write)
3. nntp.aioe.org:119 blank/blank (read/write)
4. news.mozilla.org:119 blank/blank (special purpose)
5. freenews.netfront.net:119 blank/blank (read/write)
6. news.gmane.org:119 blank/blank (special purpose)

So that only leaves port 199 in cleartext.

If anyone here knows of other free no-registration text (not binary!)
Usenet news servers, please let me know because everyone will benefit from
that information.

The players in the Pan doc dept are Douglas Bollinger and Darren Albers.

DA used to have a faq at his site, but the link is not working now. DB
made an .xml doc back in 2007, which is also not very useful for this

Probably the best place to communicate with 'Pan-people' is in the group

Thanks Mike,
I appreciate that you add value in every post, which is useful, today, to
everyone interested, and which is archived, for tomorrow, for all to
benefit.

For privacy reasons, email is problematic as I don't know how to register
for a mainstream email nowadays without giving them my phone number. So I
stay away from gmane, although I note that gmane does seem to have a no
registration (i.e., login = blank, password = blank) NNTP gateway of some
sort (which might not require email?).

news.gmane.org:119 blank/blank

The Usenet newsgroup, I think, is "gmane.comp.gnome.apps.pan.user", at
least I think so, based on the search engine I found over he

http://search.gmane.org/?query=%28x%...pps.pan.use r

Disclaim: Take all of the above with a grain of salt since I *assumed* a
lot up there in those statements since I have never tried gmane before.

PS: Don't you think pan deserves its own "real" newsgroup?
(How many people use pan anyway? Lots? Few?)

I don't give gmail a phone#; altho' gmail strongly prefers a cell# so
that they can resolve lost passwords automatically by texting the cell.
I simply give gmail an alternate email, decline the cell#.

So I stay away from gmane,


Like many many many other 'things', gmane posting requires an
operational email address. However, gmane's TMDA system for obfuscating
email addresses of posters is sufficiently protective of any email
address which is used.

PS: Don't you think pan deserves its own "real" newsgroup?


news.software.readers is the best place for Pan-related stuff; and not
crossposted to linux and windows.

In some ways, Pan's decision to drop sending the Date header is an
advantage.

- it solves the glitches in the Date header which were described in
the earlier versions
- it satisfies some people who don't like their privacy infringed a
tiny bit by the Date header disclosing their tz offset
- not sending is 'harmless' because of the uniform policy of news
servers to provide a Date header if it is missing

I don't know how many, but my guess is that it's "few."

I did a quick web search, but didn't find any statistics. Anyone know
of a site that compares newsreaders by usage?

Personally, I use and prefer tcpdump (on Linux), but I believe that
Windump's syntax is very similar.

You'll first need to get a list of your interfaces:
windump -D

The interfaces will be numbered.

Then, a typical command might be as follows:
windump -nni 1 port 119

where '1' is the interface number and the rest is obvious.

After that, you can add more options, such as '-s0' to capture entire
packets and/or '-w path/file' where path is the path to your saved file and
file is its filename, etc. Windump -h gets you a terse bit of help, or
better yet, use the docs for tcpdump.

Every once in a while some newsgroup post monthly figures, where they list
the posts by various categories, including User-Agents.

But I don't have any in my hand right now.

Just for the record, here is information about the date header from Steve
Crook, admin of mixmin.

The discrepancy between servers is almost certainly due to the INN
version they're running. Mixmin is frequently updated against the
development branch while (I expect) the others are running a stable
release. You can view the relevent code for INN he-
https://inn.eyrie.org/trac/browser/trunk/lib/date.c
Look for the function: parsedate_rfc5322_lax

The text on the last change to this file reads:-

"Use -0000 instead of +0000 as the time zone in generated headers not at
Universal Time nnrpd now uses -0000 as the time zone for Date: and
Injection-Date: header fields it generates. It was previously using
+0000, wrongly systematically indicating a local time zone at Universal
Time when the localtime paramater is set to false (which is the default)
in readers.conf. The +0000 time zone will now be used only if localtime
is set to true and UTC is really the local time zone of the server.
Improve the documentation of readers.conf, mentioning a use case for the
localtime parameter. Thanks to Russ for it. convdate now similarly also
uses -0000."

The server (by default) adds a Date header in UTC but it can be
configured to use localtime instead. In my case that would be confusing
as the server runs GMT/BST to match my local time, not that of its
location.

gmane is a mailing list to UUCP converter, as such you can read
mailing lists using a newsreader, and even attempt to post to them.
most mailing lists will hold messages with unrecognides addresses, so
for best results you should subscribe to the list before posting from
gmane (after subscribing put your account in "vacation mode" so you
don't get the list via email.

The Usenet newsgroup, I think, is "gmane.comp.gnome.apps.pan.user", at
