I don't have reasons to doubt anything, good or bad. I just like to 
confirm if this problem has propagated to other servers that I use. I 
use MixMin and news.us.Usenet-News.net and both looks OK to me but what 
worried me is that the cross-post was to some recreational books 
newsgroup. This, IMO, is a recipe to invite spam to a technical 
newsgroup such as this one.

Yes - check it on the server that had the glitch!


If you drive to the car workshop and tell them your car is making a 
funny noise, would you be impressed if a whole bunch of mechanics rush 
out and look at every other car in the car park?  Then when they find 
the other cars make no noise, they tell you it must be a troll in your car?

How is it that there are people in news.admin.net-abuse.usenet who have 
supposedly all this "experience and expertise", and are willing to look 
up messages all over the place and draw all sorts of conclusions about 
people, articles, and servers - and yet none of them seems willing to 
take a look at the server that had the glitch?


I've been involved in computers a /long/ time.  A rare glitch on a 
server does not surprise me.  What /does/ surprise and frustrate me are 
two things.

One is that so many people have been so quick to accuse and blame Bonita 
of all sorts of things, without any consideration for alternative 
explanations of events.  That includes people who know her postings 
well, and those who had not heard of her until this thread.  Neither 
groups have any excuse for their judgemental attitude.

The other is that so many apparent experts are determined to look 
everywhere except where the problem lies.  It apparently does not matter 
what details I give, what explanations I post, what guides I give to 
reproducing the problem so that you can see it for yourself.  No, 
apparently the "expert" handling is to ignore all I write, deny that 
servers can ever have glitches, and ask for more evidence.

This really isn't rocket science.  If the problem was on /my/ computer, 
it would be hard to replicate - but it is on a /free/ Usenet server. 
Make a /free/ account there, and look at the message in question.  It 
should take all of about 10 minutes - and really it only takes one of 
you "net-abuse" lot to do it (since you don't trust or believe /me/).

If you don't want to do that, fair enough.  But please stop asking how 
to verify my claims and then ignoring the answer.

We know BM, who will happily quote whatever garbage kill-filed by many in
its entirety on one hand and alter texts of actual discussion for to misrepresent
others on the other hand. Usenet is indeed getting old and unreliable and that
unfortunately adds more opportunities to misbehave.

That was good, made some "experts" to look less "apparent" for me. ;-)

I don't think anyone who is familiar with Bonita thinks she is a model 
Usenet citizen (though she is much more willing to follow standards with 
suitable quotations and attributions than she used to be).  And there is 
no doubt that quoting the entire rambling essay to top-post a single 
comment is bad style.  But that doesn't mean it is right or fair to 
accuse her of things she /didn't/ do.  news.eternal-september.org 
attributed the essay to Muttley - it was not Bonita's idea.

I tried but you need to sign up with them. This is not I can do now. We 
just have to accept that servers can go wrong. AIOE is also down for the 
past 3 or 4 days including their main website.

Headers provide clarity and tell a story.

Since the answers are in the headers, of the article on ES, providing 
them might be useful.  The overview headers, from which the news 
client generates a threaded article list, are a subset of the full 
headers.

I am particularly interested in the Newsgroups, References and Xref 
headers.

I recommend using the View/Message Source (^U), rather than 
View/Headers/All.

Whereas you read code.  I read headers.  Without sufficient 
information, either of us is likely to make errors.  I know I did, in 
this case.

Bonita saw the essay article appearing in comp.lang.c++ and replied.  That 
reply indicates she found the essay out of place and looked up the actual 
source of the plagiarized, copied and pasted text.  What she didn't notice 
was the cross-post.

While no longer available, I believe the Google Groups mystery article 
included comp.lang.c++ in the overview headers of the article.  It may 
have also appeared in the Newsgroups header, but my time machine is in 
the shop.

As Ray rebuilt the corrupted overview database, the *glitch* appears 
rectified.

I'd like to apologize for my jumping to conclusions based on a lack of 
direct evidence.  I also created an E-S account, just for the telnet 
access, at David Brown's recommendation.

I am sorry I jumped to conclusions, without having the evidence in 
hand.  I'll have to review *my* headers, now.

That is what I have generally done, though I did not always post all the 
headers.  (To be honest, I used "view source" because it is quicker to 
use a shortcut key, rather than because I thought it would give more 
information.)

Sure.  And we all get things wrong sometimes, or misunderstand - it's 
particularly easy when dealing with people who are not familiar with all 
the right terms or which details are important.  (I am also a server and 
network administrator, with plenty of experience of a variety of server 
setups - but I have never had cause to learn about NNTP servers.  And I 
have plenty of experience of assuming the user is the problem, rather 
than an issue with the server!)

Thank you for saying that.  I know I've learned a lot about Usenet from 
this discussion, and I am glad to see others have learned something too. 
  Usenet seems to be an extraordinarily robust system, that has run for 
decades with very little in the way of technical problems (merely human 
problems).  It makes sense to consider such server glitches as so 
unlikely that you have to eliminate other explanations first - but it 
turns out that one in a million chance events do happen sometimes!

That requires setting up an account. That didn't seem to
be necessary as the way you described the problem made it
seem like it was not a server problem.

You mis-explained in a way to lead others to misunderstand the
problem. The problem of Bonita's post and the second problem
of the server error, which apparently was coincidental. I'm sorry
to misunderstand about the server problem.

What?  What part of "this is clearly a server glitch", "it is only 
visible with news.eternal-september.org", and pretty much everything 
else I wrote, could be interpreted as "not a server problem" ?

To be fair, the news.admin.net-abuse.usenet followers might not have 
read from the start of the thread as seen on comp.lang.c++, and thus 
missed some of the earlier posts.  But everything I have written since 
the cross-posting has been clearly about a server glitch and desperately 
trying to persuade the Usenet experts to look for themselves on 
news.eternal-september.org so that they can see the difference.  Those 
who /have/ now looked have been in no doubt - it was a server glitch.

I do appreciate that setting up an account on that server is an 
inconvenience and effort, and people could have a wide range of good 
reasons for not wanting to do that.  I do not expect any particular 
person to make an account and check it.  All I expect is that people who 
choose not to go to the source and look at the primary evidence, should 
not profess an "expert opinion" on the matter.

There were not two coincidental problems - there was /one/ problem.  A 
server glitch.

Bonita made a post in poor style - quoting an entire long message with a 
single top-posted comment.  Usenet is swamped with people who do that - 
it is not some rare or unusual "problem", and if people complained to 
admins about "abuse" for such posts, admins would see nothing else.  You 
can be sure that none of the regulars in comp.lang.c++ would bother 
about it.

But that's what these newsgroups are all about.  Not letting not knowing
anything stop you from giving advice.

Just look at all the nonsense you (and that other poster) have spewed in
that other thread - the one about modifying object modules using
established working tools.  You guys (both of you) need to look up what
"IMHO" means - and start liberally using it in your posts.

It's not used to indicate /whose/ opinion it is, it's used to emphasise
that what is being presented in now firmly in the domain of opinion and
not fact.

I thought so because it is one of the first things you should have mentioned
in the very first post you talked about a server glitch. You are a technical
person , you *know* that for bugs , glitches , etc. one ideally should
mention precise steps which would allow one to reproduce the problem. So I
can't imagine what you were thinking in failing to do so. It couldn't have
been for lack of time because you posted some very long responses which were
light on technical content but made no mention whatsoever of the very
important fact that you could consistently reproduce the problem. In fact ,
in at least 4 posts you said "a server fault" or something analogous without
mentioning that there was one specific server on which you saw the issue. I
was actually wondering what the hell was happening and you weren't giving
specifics.

This isn't very helpful and in particular it doesn't help to distinguish
whether it's a server issue or a Thunderbird issue. Just because Thunderbird
threads posts in a certain way or puts some post under a certain group ,
does not imply that the server has the same view of things. Perhaps Thunderbird
received correct responses from the server and messed things up. Below I will
give 2 precise ways to reproduce the problem which clearly show that it's an
eternal-september  issue. Before doing so I will note that when you want to
talk about the date of a message it is best to quote the following 2 lines from
the header

    Date: Thu, 19 Jan 2023 01:42:00 -0800 (PST)
    Injection-Date: Thu, 19 Jan 2023 09:42:01 +0000

instead of saying for example (from  <tqoluk$5cht$2@dont-email.me>)
"timestamp 19.01.2023, 10:31" .If Thunderbird does not allow you to see the
header exactly as it received it from the server then it's no good for
diagnosing issues.


For both of the following methods one must have an  eternal-september  account
since this is the server which displays the issue.

     Method 1

You need to have the  lynx  text based browser installed. You do

    lynx news://news.eternal-september.org/comp.lang.c++/137660-137665

.This asks  lynx  to contact  news.eternal-september.org  and fetch article
numbers 137660-137665 from the group  comp.lang.c++ .Note that article
numbers are server and group specific , a different server might not have
articles with such numbers or they might refer to different posts. But the
important point here is that whatever posts the server returns , they must
have been posted to  comp.lang.c++ , possibly among other groups. The first
post you will see is

Newsgroups: rec.arts.books
Date: Thu, 19 Jan 2023 01:42:00 -0800 (PST)
Message-ID: <36403165-3cf1-4b73-8ad1-da339b960339n@googlegroups.com>
Subject: Change and Choice
From: Ilya Shambat <ibshambat@gmail.com>

.Note that it was not (cross)posted on  comp.lang.c++  so it should have
never been returned. The last post you will see in the above list is

.This correctly appears in the response by the server since it was crossposted
on  comp.lang.c++ .

     Method 2

You have to run a Python script which I will give below. It runs on Python
2.5 .Yes it's an old version but it's the only one I have handy and I haven't
bothered to learn Python 3.whatever .But the script should run on the newest
Python with little or no modifications. You run the script with

    python path-to-script username password

where  username  and  password  are the ones you have for  eternal-september .
The script will append its output to file  /tmp/server-glitch-2 .

==== Script starts on the next line
import os
import string
import sys
import nntplib
import datetime

class TerminateError(Exception) :
    def __init__(self , message) :
        self.mes = message

    def __str__(self) : return self.mes

def terminate(*args) :
    global util_name

    mes = util_name + " :"
    for a in args :
        mes = mes + " " + str(a)
    raise TerminateError(mes)

util_name = "server-glitch"
server = "news.eternal-september.org"
separ = '\n@@@ \n\n'
port = 119

if len(sys.argv) != 3 :
    terminate("2 arguments required : username and password")

username = sys.argv[1]
password = sys.argv[2]

fnobj = open("/tmp/server-glitch-2" , "a")
now = datetime.datetime.now()
fnobj.write("Starting at  " + now.strftime("%Y-%m-%d  %H:%M:%S %z") + '\n\n')

try :
  connection = nntplib.NNTP(server , port , username , password)

  response = connection.group("comp.lang.c++")
  fnobj.write("Response choosing  comp.lang.c++  was\n\n" + str(response) + "\n\n")
  response , overviews = connection.xover("137660" , "137665")
  fnobj.write("Response asking for range of articles was\n\n" +
      str(response) + "\n\n")

  for art in overviews :
     fnobj.write("Article number " + str(art[0]) + " :\n")
     fnobj.write(str(art[1]) + "\n\n")

  for art in overviews :
     response , number , id , content = connection.article(str(art[0]))
     if id == '<36403165-3cf1-4b73-8ad1-da339b960339n@googlegroups.com>' or \
        id == '<tqbkrr$1ja1c$1@dont-email.me>' :
            fnobj.write("Printing article number " + str(art[0]) + " :\n\n")
            for l in content :
                fnobj.write(l + '\n')
            fnobj.write(separ)
     else :
            fnobj.write("Skipping article with id\n    " + id + separ)
  connection.quit()
except nntplib.NNTPError,exception :
  terminate("NNTP error\n" , "Exception was\n" , exception)

now = datetime.datetime.now()
fnobj.write("Terminating at  " + now.strftime("%Y-%m-%d  %H:%M:%S %z") +
    '\n\n  =======\n\n')
fnobj.close
====

The important points are the following :

server = "news.eternal-september.org"

  connection = nntplib.NNTP(server , port , username , password)

  response = connection.group("comp.lang.c++")

It connects to  eternal-september  and goes to  comp.lang.c++ .

  response , overviews = connection.xover("137660" , "137665")

Asks for list of articles from 137660 to 137665 , same numbers as with
lynx  above.

Then it goes through the articles one by one and puts in
/tmp/server-glitch-2  the articles with IDs
<36403165-3cf1-4b73-8ad1-da339b960339n@googlegroups.com>  and
<tqbkrr$1ja1c$1@dont-email.me> .It puts the articles exactly as it receives
them from the header. Again you will see that the Shambat article has

    Newsgroups: rec.arts.books

so it should not have appeared under  comp.lang.c++  regardless of what
range of articles we asked for.

If I had tested with Pan at that point, I would have mentioned it.  I 
have tested more as I investigated further - I have also learned from 
other people's posts.

I have tried to give specifics as people have asked for them, as well as 
guidance to reproduce the problem.  At the start, however, I had no idea 
how widespread the issue might have been - maybe it was temporary, maybe 
it was related to the client, maybe it had propagated to all Usenet 
servers.  When I first saw it, I assumed it was local to my PC - it was 
only gradually that I realised Bonita had seen the same glitch I had, 
and it was not just on my system.

The screenshot is not Thunderbird, it is Pan.  Thunderbird and Pan 
appear to show threads in exactly the same way, as far as I could tell.

Pan and Thunderbird are both perfectly good for diagnosing that there 
was a ****ing server glitch that meant the wrong article was returned 
for the message id in the header.  I didn't know how to make Pan show 
the message ID from the header until just recently.  But you don't need 
the id or other information to see that there is clearly a mismatch.

Correct.  It should never have been there - it is a result of the glitch.

I have Python 2.7, rather than 2.5, on this system.  But it works fine 
there too.  Python was my first thought as a way to do a 
newsreader-independent check of the issue (I had no idea that lynx could 
handle the NNTP protocol).  I hadn't bothered trying it because I had 
confirmed the issue with a different newsreader (Pan).

But trying your script gives the expected result - the rec.arts.book 
article is returned by the server when asking for articles that appear 
in the overview data for comp.lang.c++.

Thanks for making these recipes and the script, and confirming the glitch.

That screen makes no sense and I would guess it to be a
Thunderbird problem. Thunderbird on mac has been broken
for me for many months and have quit trying to make it work.
A client problem, not a server problem.

So Thunderbird is broken or semi-broken depending on
Mac (broken), Windows (semi-broken), or Linux (somewhat
broken).

If Mozilla (Thunderbird) doesn't want to support newsgroups
anymore, they should stop pretending to. This is me jumping
to conclusions.

It's a screenshot from Pan, not Thunderbird.  (You realise this is 
Usenet, don't you?  It is not personal email - you are allowed to read 
replies I have made to other people.  Indeed, it's a good idea, and 
saves repetition.)

It makes no sense because it shows a /server/ problem - the /server/ 
returned nonsense for that post.

I've found Thunderbird to work fine on Linux (I also use it on Windows, 
but not for Usenet).  It's not perfect, but I've found few programs that 
/are/ perfect.  And it shows the same glitch here as Pan does, because 
it is a /server/ glitch, not a client issue.

While that may be possible, it is unlikely in this case.  You, on the 
other hand, are simply mistaken about what you believe you saw.

What, pray tell, is the M-ID for the original essay, as you observed 
it on ES?  Show me.

In this specific incidence, I have yet to see anything which supports 
this notion.  Show me.

My first request was for a vowel^W Message-ID.  I then looked at the 
headers of the article, to which I was replying, which told the story 
in the References headers of <JaMukkKxSBcM7VPWN@bongo-ra.co> 
(<http://al.howardknight.net/?ID=167449837100>).

Notice, the thread begins with the "Change and Choice" article, posted 
via Google Groups.  This article appears only in rec.arts.books.

Keep in mind, many NNTP clients use the Reference header for the purpose of 
threading.  It's fairly cheap, as the References are an overview header, 
like the From, Message-ID, and Xref headers.

Both are irrelevant.

This is a different thread.  It is completely unrelated to my 
examination, here.

Human readable Subjects are included for humans.  M-IDs and References 
are included so that machines and processes can work with them.

I don't particularly care, as its a different thread.  The troll changed the 
Subject, to "Re: Compute Unique Numbers in a Set."  This does not make it 
part of the same references based thread.  You were trolled by a Subject 
line modification.

So what?  It's the beginning of a new, completely unrelated thread.

Please see my headers, regarding invalid assumptions.

There was no link, beyond a Subject change in the X-posted troll.

You're here, theoretically in order to learn from my experience and 
expertise.  I read headers.  I try to steer clear of idle speculation.

The References, in the original Compute Unique Numbers thread, do not 
appear in the headers of this or any other message, which begins with 
"Change and Choice" based thread, beginning with 
<36403165-3cf1-4b73-8ad1-da339b960339n@googlegroups.com> 
(<http://al.howardknight.net/?ID=167449810000>).  Look at the 
References.

You were trolled.  Get over it.

He's posted a screenshot of what he "believes" he saw. Do you claim that
the screenshot is a forgery?

Snipe posted a message pointing out that the newsgroup
eternal-september.support had messages in it from the system
administrators acknowledging that there had been some server glitches
recently.

Looking at that newsgroup, it appears that they've had a flurry of
messages about a variety of server problems for a week now, and took the
server down to resolve the problems a few days ago. As far as I can
tell, they do not mention this particular glitch in that newsgroup, but
the other glitches they've had around the same time makes it more
plausible that this particular incident may also have been the result of
a server glitch.

> What, pray tell, is the M-ID for the original essay, as you observed

According to David's own message with the ID
<tqoluk$5cht$2@dont-email.me>

the message-id was
36403165-3cf1-4b73-8ad1-da339b960339n@googlegroups.com

Which matches exactly the message id you give:

Since David asserted that what he saw was a message header list that
matched the message actually posted by Muttley to comp.lang.c++, and
that the corresponding message body had headers that matched the message
actually posted by Ilya Shambat to rec.arts.books, that is consistent
with what you saw.
What newsserver did you use to view those messages? If the server
problems mentioned in eternal-september.support are in fact relevant,
you SHOULDN'T be seeing the same thing he does, unless you're using
eternal-september as your server.
I didn't see that message, despite the fact that I do use
eternal-september.org, but that's because Muttley's on my killfile, so I
can't personally confirm what David is saying.

Again, you are wrong.  I am not mistaken, and this has been confirmed in 
several ways.  Please read my other posts in this thread to see my 
descriptions of the problem and how it appeared, details of the message 
ID's, a description of how to replicate the issue, and a screenshot 
showing it.

Oh, wait - you /did/ read them, as you quoted them below.  And yet you 
deny them blindly.

There was also a post from Sn!pe confirming that the admin of the 
news.eternal-september.org was aware there had been a synchronisation 
issue between the overview database and the main message database on 
that server - /exactly/ the kind of server glitch that could lead to the 
effect seen.

And yet you conclude - with certainty - that there was no failure here?

Incorrect.  You are mistaken.

The article did not appear in comp.lang.c++ on any of the newsservers 
/you/ looked at.  It /did/ appear in comp.lang.c++ on 
news.eternal-september.org.

I do not know if it also appears in rec.arts.books on 
news.eternal-september.org - I have not looked at that group.


(It also appeared in a quotation in the post made by Bonita.  That was 
made as a normal post by Bonita, quoting the message as it appeared on 
news.eternal-september.org.)

Incorrect.  Again, you are mistaken.  It appears on the server 
news.eternal-september.org in the group comp.lang.c++, exactly as I said 
it does.  This is the result of a server glitch - a synchronisation 
issue between the overview database and the main database.

I believe I am safe in asserting that you have not checked /every/ NNTP 
server for this post.  In particular, I am entirely confident that you 
have not looked on the relevant server - news.eternal-september.org.


> If you believe otherwise, show me; make me eat my words.

I have shown you.  I have given a screenshot, and detailed instructions 
on how to see the problem for yourself.  That requires you to make an 
account on news.eternal-september.org so that you can see the problem there.

I hope that you will do so.  You will learn a little about what can go 
wrong in Usenet servers, and perhaps also why it is not good to jump to 
conclusions or make too many claims before you have looked at the details.

I am aware of how the messages appear on other servers (I used Google 
Groups to check, for practical convenience).  Other servers did not see 
the mismatch between the overview header and the message body.

We are familiar with Bonita in comp.lang.c++.  Yes, she posted it.  No, 
it was not a troll - it was a somewhat snarky response to what she 
thought was a mixed up post by Muttley.  There are plenty of people here 
who dislike some of Bonita's habits - but I have no doubts at all that 
she genuinely believed Muttley had written that rambling essay for 
rec.arts.books, and had accidentally cross-posted it to comp.lang.c++. 
I thought so too, when I first saw it - people accidentally posting to 
the wrong group is much more common than server glitches.

Bonita is guilty of blindly quoting an entire OT post and top-posting a 
one-line comment on it.  That's not good Usenet etiquette.  But it was 
not trolling, forgery, or intentional misrepresentation - and I do not 
like to see anyone falsely accused of that.  It is correct that Muttley 
did not write the original essay - and it is therefore incorrect for 
Bonita's post to have the attribution "Muttley wrote ...".   But that 
attribution is because the newsserver Bonita used, 
news.eternal-september.org, had attached the essay message body to the 
overview header of a post Muttley /did/ write.

Incorrect.  Again, people who are not using news.eternal-september.org 
did not see the quoted post.  People who use news.eternal-september.org, 
did see it.

I later found I could show you more - including a screenshot for your

No salt is needed.  Unless you have already jumped to a conclusion and 
are unwilling to look at evidence and information, then you should have 
realised that my experience of the post is different from yours.  This 
should lead to a line of inquiry of /why/ it is different.  Was it a 
temporary thing?  Something local to my computer?  An issue with my 
newsreader client, or with the server I used?  How many people saw what 
I saw, how many saw something different?  What are the common factors 
distinguishing the groups?

Of course, that requires you to be of the "Sometimes I don't know 
everything" and "Sometimes different people see different things" 
schools.  Being of the "Show me" school doesn't help if you are not 
willing to look when people show you.


I had already figured out, before the thread was cross-posted to 
news.admin.net-abuse.usenet, that this was a server glitch that had not 
propagated to all servers - though I did not know at the time that it 
was found only on the one news.eternal-september.org server.

Nope.  Wrong again.

It quickly became clear that the client did not matter - it was 
coincidence that the three people who saw the mismatched post used 
Thunderbird.  But the /server/ - that is critical.

It is a different thread, yes.  It is absolutely critical to the matter, 
as it is in /that/ thread that the mismatched post appeared.

You'd know that if you followed my suggestions and looked for yourself.

It is quite clear that there has been a glitch on the 
news.eternal-september.org server.  You can look at Sn!pe's post, and 
the link he has to a message from the admin of that server, discussing 
the glitch on the server.

I am really hoping your response has changed by now.

Right.  So the one server where there is a problem that you could easily 
see, you have not looked at.  And yet you feel confident in claiming 
there is no problem with that server.

The issue is still there - I checked anew with a fresh pan installation 
on a different machine.  You have to connect to the server you claimed 
is irrelevant, and look at the thread you claimed is irrelevant.  Or is 
"Show me" just a mantra to you, rather than something you actually want?

And yet you are idly speculating that I am wrong, every piece of 
evidence and guidance I gave is irrelevant, and that your experience and 
expertise lets you pronounce judgements without looking at what has 
happened.

No, /I/ did not come to this group for your expertise and experience. 
Someone else in comp.lang.c++ made the cross-post, hoping for ideas. 
Sn!pe's post is an example.

Now, I am sure you have plenty of expertise and experience in Usenet and 
the servers - I just use it, I don't run a server.  However, it seems 
this particular case is outside your experience - /you/ have the chance 
to learn here.  That's great, of course, if you are open to it.  None of 
us are so good at anything that we can't learn more.  It turns out that 
what appears to be your usual investigative process, with a focus on 
message ids, let you down in this case.

You were wrong.  Learn from it.
