Simple question : using the NNTP protocol - How do I check for newsgroups that have been removed ?
I don't really want to go thru the list of all newsgroups I currently have stored and check, one by one, if I they are still present on the newsgroup server.
Remark: I found the command to find all *new* newsgroups (since a certain date), but have not been able to find its opposite.

There isn't a method defined in any RFC to do so, because there are a
number of hurdles that make it infeasible:
- *WHO* decides what groups to include on that list?
- How far back do you want to go/removed since *WHEN*?
- For each user, the server would need to remember the last time that user
checked the groups, and what groups have been removed since then.
*WHERE* does the server store this information?
- *WHY* would the server retain information it has already removed?
The *only* method to do this is using the "LIST" command.
Alternately, you could send the "CAPABILITIES" command and see what the server returns. Maybe your chosen server has a method to do what you
want. (Don't count on it.)

Rather than infeasible, it's more likely to be trivial.
- *WHO* decides what groups to include on that list?
The user who sits behind the news client or script that provides the capability.
- How far back do you want to go/removed since *WHEN*?
Since the last time this user performed this check against this server,
using this client/script.
- For each user, the server would need to remember the last time that user
checked the groups, and what groups have been removed since then.
*WHERE*
does the server store this information?
The server would store nothing. The client or local script would store everything.
then it could compare the new file to the old file, diff-like, to see
what's been added. That much is trivial, and once it does the diff, I
don't see why there couldn't have been an additional view that shows
the groups that have been removed since the last check.
It seems to me that any client that uses a newsrc file could be used as
the basis for determining which groups are New or Old since the last
time the command was run.
Hello all,
Simple question : using the NNTP protocol - How do I check for
newsgroups that have been removed ?
It's very simple. Just subscribe control.rmgroup newsgroup on your newsserver.
* control messages may expire like other messages and you can't see old messages.
Andrzej,

newsserver.
* control messages may expire like other messages and you can't see oldYep. Though in the case of ES the retaining time seems to be at least a decade (earliest entry is of march 2015). :-)
messages.
The control.* newsgroups usually keeps only control messages sent to the specific newsserver -
either by the newsadmin or by approved users of that server (f.e. cancel messages).
E-S in general has 8 year retention.
If you want to know more details,
If you want to talk about newsgroups subscribed in your newsreader, you should rather use term "offline".
Andrzej,

You mean, that subtree is not replicated to all the other newsgroup servers
? Any idea why not ?
either by the newsadmin or by approved users of that server (f.e. cancel
messages).
Although I took the latter part for granted, I mentioned something in relation to the former (dashboard). And as that has not been adressed ...
E-S in general has 8 year retention.
If you want to know more details,
No. If its supposed to have a specific behaviour its likely in an RFC somewhere. If its not than the info would not be worth anything in regard
to any other newsgroup server.
Ah yes : last mentioning (that I have) in RFC 5537, chapter 5.2 - Group Control Messages.
And that also answers my above "any idea why not?" question, as it looks
like that they are indeed replicated to other servers too. Which makes sense.
And as it doesn't seem to mandate that all newsgroup deletions /must/ be going thru the "rmgroup" newsgroup ... I still cannot use it to (fully) clean-up my local newsgroup list.
If you want to talk about newsgroups subscribed in your newsreader, you
should rather use term "offline".
:-) Offline ? Couldn't there be a more meaningless name for it ?
I referred to those lists as "local" and "server" from a users perspective (which is what I am and the POV I wrote my message from). But if someone wants to refer to them regardless of perspective than I suggest naming them "server" and "client" (newsgroup) lists. No ambiguity, no matter which POV is taken.

I am wondering why your ? always has that space between the last letter
and it's placement? Even the subject of this thread has it?
Sticks,

Simple answer ? Because I think it aids in easy recognision of the word just before it.
But a reverse question : why do you guys always seem to preceede the word "too" with a comma ? Like "lets do that, too". Whats the rub with that ?
I do not see any reason for, or function of it.

...I do not see any reason for, or function of it.
I would not normally talk about commas, especially in this newsgroup,
but since you did, you should have put a comma after "or function of."
And "lets" should be "let's" and "whats" should be "what's."
OK. I was wondering if it was a coding problem of some sort, or
an intentional error on your part. Thanks
It is not necessary in your sentence example, but it can be used for
context. There are situations where it is necessary, but I'm sure you already know that.

Welcome back, Ken. I was just wondering where you'd gone. :)
Ken,

The parts are ment to be of equal weight. And in that case, as far as I >know, a comma is not called for.
And "lets" should be "let's" and "whats" should be "what's."
Well, you got me there. I never can remember when those quotes are supposed >to be used, and even less when they should appear on the end of a word.

Zaidy036,
In a backup just search for news.<newsprovider>.org.rc
I'm sorry, but I have absolutily no idea what you are talking about there, what backup (of what) do you mean ?
And to forgo any confusion about it, I'm talking from the perspective of a newsgroup *client*.
Regards,
Rudy Wieser
Zaidy036,
Any image or other backup.
So, just any random backup ? I guess I could grab my backups of my C89 installation disks ...
Again, a backup of *what*. I have zero clue what you are talking about.
news.<newsprovider>.org.rc contains message status
Is that a newsgroup ? If so, I have not been able to find it in my
newsgroup reader.
----Partial sample of mine in a text editor:[snip]
That looks like the output of the NNTP "groups" command. But if I would
want to go that way I would need a current version of that list, not a stale one.

Rudy Wieser

Welcome back, Ken. I was just wondering where you'd gone. :)
Thanks. I've had some serious health issues. I'm still not 100%, but
I'm much better.

that depends on how many backups you keep for how far back.
Zaidy036,

Ah, you're not here to help, but just to troll about. Alright, than I will leave you at it.
Goodbye.
