Request -moderated groups


I have a problem - the news server upstream from here is bad at dealing with 
moderated groups (about 1 in 5 posts seem to make it!), and the ISP doesn't 
seem interested (or possibly can't work out what the problem is).

I was hoping that using a local server on my system would get round this, and 
leafnode looks good - but all it does is pass the moderated posts upstream, 
so straight back to the problem server!

Is there any chance of any development to leafnode so that it would (perhaps 
optionally) mail moderated group posts to the moderation address rather than 
send them on to the upstream newsserver?  

I'd be glad to help, but my programming skills are, well, amateur: so far, 
looking at the code, I haven't even worked out where the leafnode suite 
identifies moderated posts to flag them for posting only once!

You might want to try leafnode-2 (alpha version, but should work OK) and
configure the moderator address explicitly (see README.html for
information on the moderators file format). leafnode-2 address:
<http://home.pages.de/~mandree/leafnode/beta/>

Let me know if that helps.

Thanks for the suggestion - before compiling it (I've got something else in 
the middle of a compile at the moment!), I've looked at readme.html.   This 
seems to indicate that moderators can only be set for *local* groups - is 
that not the case?

If not (ie if explicitly setting a moderators address for an external group 
will work), then this sounds exactly what I need!  Not the first time I've 
asked a Linux programmer about a feature only to find someone else has 
already made it work :-)

The moderators file was added for local groups but supports
non-local groups as well.

Thankyou - I'm trying it and it seems to be working exactly as I need it to.

A question: how difficult would it be to add functionality to make this happen 
for any moderated group, without having to add addresses manually 
to /etc/leafnode/moderators?  What I'm thinking is this: a format for a line 
in the moderators file something like

uk*:  <at> usenet.org.uk

... to apply to moderated groups in the whole uk.* hierarchy, simply adding 
' <at> usenet.org.uk' to the newsgroup name for the moderation address. 

From a very quick look at the code in moderated.c, I think I could manage to 
write something to parse this sort of line and add it in there - if 
getmoderator() only gets called for moderated groups, then I think that would 
make this work.

Again, it's already there. The line for this would read

uk.*:%s <at> usenet.org.uk

> From a very quick look at the code in moderated.c, 

Check lines 47-59 again :-)

Great!

Ah, yes.   I thought it was just a standard printf format string token being 
used in a way I hadn't fully grasped!

Thanks - this is exactly what I needed.

It can only be set for *moderated* groups, whatever their origin.

As no-one has responded yet, and stating the obvious: the Microsoft
Knowledgebase might have information on that. Perhaps there is an
explicit or hidden registry option or something to limit the amount of
connections per server.

per_source = 3 is a bit low and lower than what's recommended for IMAP,
for instance - I'd set this to 6 if possible, and bump instances
accordingly (perhaps 15) if your server can stand the memory load.

groupinfo has lost some moderated flags

[leafnode version 2.0.0.alpha20050810a]

I recently did a fetchnews -f in order to solve a problem and I've just
noticed that various moderated groups are now not moderated according to
the groupinfo file (I've no evidence that it was the -f that did it but I'm
pretty sure it was ok until very recently)

So I have (starting at the end)

200 Leafnode NNTP daemon, version 2.0.0.alpha20050810a ...
list active za.net.maps
215 Newsgroups in form "group high low flags".
za.net.maps 0000000001 0000000001 y

but the upstream servers have
za.net.maps 0000001004 0000001002 m (ntlworld)

za.net.maps 0000000005 0000000004 m (news.individual.net)

there are various others locally that are similarly incorrect, but some are
fine e.g.

200 Leafnode NNTP daemon, version 2.0.0.alpha20050810a ....
list active wales.usenet.announce
215 Newsgroups in form "group high low flags".
wales.usenet.announce 0000000001 0000000001 m

should I try another fetchnews -f - is a debugmode setting at the same time
recommended in case it's a leafnode problem?
