This document is intended only for those who’re running a real USENET site with regular real-time feeds with other peers. All other people - notably the end users - can safety forget it.

1. Introduction hosts a small USENET hierarchy - aioe.* - with a few text only newsgroups. Since propagates these groups to the other USENET peers that have established a feed with our hosts and an increasing number of sites is starting to carry them, this pages offers all the informations needed to properly handle our hierarchy.
aioe.* is mostly used to provide our users with some sort of helpdesk or message board but if some customer asks for a group with sensible reasons we often agree to create it. Control Messages - except checkgroups - are rare and the traffic volume is low, about a few KBytes of traffic per day. Other useful informations about the aioe.* hierarchy are available in this specific page about it.

2. Checkgroup

The complete list of all newsgroups currently included in the aioe.* hierarchy - which is often called checkgroup - is available at Those sites that are running INND should update their active file with the following commands:

$ su news $ wget 
$ /usr/lib/news/bin/docheckgroups <checkgroup.txt | /usr/lib/news/bin/mod-active

Those who prefer actsync, should add at the beginning of /etc/news/actsync.ign - after the set of BIG8 hierarchies - the following string:

c aioe.*

The synchronization is made with

$ su news
$ actsync -v 2 -i actsync.ign | /usr/lib/news/bin/mod-active

A checkgroup - which is a control message that summarizes the list of all groups currently active - is sent once per month so those who have configured their hosts to process this kind of incoming control articles can safety forget checkgroups after the first initial sync


3. Moderators

Even if aioe.* doesn't contain at the moment any moderated group, we're planning to offer that kind of service. In order to properly handle messages sent to aioe.* moderated groups, it's needed to add to /etc/news/moderators this entry



4. GPG Key

In order to avoid serious abuses, all control messages sent by are signed with a PGP key. We strongly recommend to configure controlchan in order verify the sign of each control article before processing it. Our key - which has got a KeyId number 0x2322A7F8, fingerprint 2203 1AAC 51E7 C7FD 664F 1D80 90DF 6C71 2322 A7F8 and belongs to - is available at or through every public keyserver. In order to import that key, these are the suggested steps:

$ su news
$ wget
$ gpg --import aioe.txt

5. Control.ctl

Control.ctl is the configuration file that determines how the news server has to threat the incoming control messages. In order to handle the control articles sent by for the aioe.* newgroups, it's needed to add at the end of /etc/news/control.ctl the full contents of in this way

$ su news
$ wget
$ cat control.ctl >>/etc/news/control.ctl

Since this file includes all informations needed by the newsmasters about each public hierarchy, we reproduce it here:

## Aioe
# Contact:
# URL:
# Admin group: aioe.system
# Key URL:
# Key ID: 0x2322A7F8
# Key fingerprint: 2203 1AAC 51E7 C7FD 664F 1D80 90DF 6C71 2322 A7F8
# Syncable server:

6. AntiSpam settings

aioe.* is protected against spam, floods and other massive abuses through NoCeM. When an aioe.* newsgroup is involved in some large abuse, those people who maintain the hierarchy detect by hands which articles have to be deleted than send a NoCem message. If the remote server are configured to accept and process those messages, all offending articles are locally rejected as shown in the NoCem notice. All NoCeM notices pertinent to aioe.* are sent to news.lists.filters and from with type aioe-spam and all messages are signed with the key 0xA9708492 that is available at
A good guide about NoCem and INND is available at
In order to add our NoCem service to an existing server, it's needed to import the NoCem key in the keyring used by perl-nocem:

$ su news
$ wget
$ gpg --no-default-keyring --keyring /etc/news/pgp/ncmring.gpg --import nocem.txt

It's also needed to configure /etc/news/nocem.ctl in order to accept the NoCem notices sent by

$ echo "nocem\*" >>/etc/news/nocem.ctl
