Re: [NNTP] Command to list wanted groups for transit peers

Hi River,

I do not know whether you have advanced a bit on that topic since last ye=
ar.
Anyway, here are a few links...

Though not the same, but could be used in a similar way, a draft
for Dynamic Feed Adjustment was published a decade ago:
    http://www.eyrie.org/~eagle/nntp/drafts/draft-court-dynfeed-01.txt

> S: 2xx List of groups follows.
> S: *
> S: @alt.sex.*
> S: @*.bina*
> S: de.bina*
> S: !uk.test
> S: .

It would also need adding the maximum article size or things like that,
possibly related to each line returned by the command.

It could also be a new keyword to the LIST command.

In case it could help, here is a thread we had in December 2009
in news.software.nntp:

"Proposal for a standardized LIST MOTD command"

[Paolo Amori]
LIST MOTD (without argument)

should/must include several data about the server (ie. Tech Contact, Lega=
l=20
Contact (the was requested me by the italian police: how can i find the o=
ne=20
who maintains an NNTP site using *only* the server itself?), Max Article=20
Size (and other newsfeeds flags), Web site). They should be shown in a=20
standardized way in order to allow people to easily understand them.=20
It could also be used as a standardized way show peering data (but a=20
standard doesn't exist at the moment)

i'm thinking about somewhat like this

LIST MOTD <GROUP>

should include the manifesto of each group (they'are collected so it shou=
ld=20
be easy to find them, i suppose)




imho, it's a need.
I've about 40 peers, each one with different peering data. Sometimes, dat=
a=20
are subjected to changes. There's no common places where peering data can=
 be=20
found and many news server don't show these data in their web sites.=20
A way to know which parameters are requested by each peer is useful and h=
as=20
the advantage to avoid 'third party' configuration errors.

btw, i *strongly* need a standardized way to show which is my legal conta=
ct=20
(the email address that police *must* use for court orders and legal=20
requests). It can be shown inside 'HELP' or 'LIST' output but it's needed=
 an=20
official paper that says to use *that* address for such requests.




> Is an RFC considered as an official paper for police?
yes. I've made the same answer to them in an interview room, after three=20
hours wait.

> Should ask the question to a policeman :-)
it should be a great idea. Interpol said me that an official statement is=
=20
needed, policeman were convince themselves that newsgroups are 'google=20
groups' and so they wanted from me 'apache logs'.

> Well, maybe you need another address than the one for abuse requests...
yes, of course.
Abuse desk is a common email mailbox. Legal contact goes to my mobile pho=
ne=20
or laptop.
