Votebot
~~~~~~~
The :ref:`Votebot <votebot>` is a custom developed IRC daemon that is packaged
as a self contained Java jar archive. The bot is started manually as described
above. For improved maintainability it should be packaged and provide a start
mechanism that is better integrated with the system.
.. _votebot:
.. topic:: Votebot
The vote bot is a Java based IRC bot developed at
https://github.com/CAcertOrg/cacert-votebot. The bot is started manually by
running
.. code-block:: bash
java -DvoteBot.meetingChn=SGM -cp VoteBot.jar \
de.dogcraft.irc.CAcertVoteBot -u -h 10.0.0.14 -p 6667 --nick VoteBot
.. todo:: use a CAcert git repository for votebot
.. todo:: package votebot for Debian
.. todo:: provide a proper init script/and or systemd unit for votebot
Kiwi IRC
~~~~~~~~
Kiwi IRC is a nodejs based IRC web client. The software has been installed via
`Github <https://github.com/prawnsalad/KiwiIRC.git>` and npm as described in
https://kiwiirc.com/docs/installing and
https://kiwiirc.com/docs/installing/proxies. The software is running on the
local loopback interface and Internet access is provided by an nginx reverse
proxy that also provides https connectivity. NodeJS and npm have been installed
from Debian packages.
Risk assessments on critical packages
-------------------------------------
Votebot is a Java based application and therefore Java security patches should
be applied as soon as they become available.
Kiwi IRC is nodejs based and uses some third party npm packages. The
application is kept behind a reverse proxy but it is advisable to make sure
that available updates are applied.
.. todo:: implement some update monitoring for Kiwi IRC
Critical Configuration items
============================
Keys and X.509 certificates
---------------------------
.. sslcert:: irc.cacert.org
:altnames: DNS:irc.cacert.org, DNS:ircserver.cacert.org
:certfile: /etc/ssl/public/irc.cacert.org.crt
:keyfile: /etc/ssl/private/irc.cacert.org.key
:serial: 0FBBE0
:expiration: Oct 22 15:27:04 16 GMT
:sha1fp: 82:F7:B8:08:FB:FD:C3:FA:21:6C:89:B7:07:69:3D:66:F8:BC:5F:AA
:issuer: CA Cert Signing Authority
.. index::
pair: inspircd; configuration
inspircd configuration
----------------------
Inspircd is installed from a Debian package. It is configured via files in
:file:`/etc/inspircd/`. The main configuration file is :file:`inspircd.conf`.
.. index::
pair: atheme-services; configuration
atheme-services configuration
-----------------------------
Atheme-services is installed from a Debian package. It is configured via
:file:`/etc/atheme/atheme.conf`.
Kiwi IRC configuration

the configuration is changed it can be applied by running:
.. code-block:: bash
sudo -s -u kiwi
cd ~/KiwiIRC
./kiwi reconfig
nginx configuration
-------------------
The nginx configuration for reverse proxying Kiwi IRC is stored in
:file:`/etc/nginx/sites-available/default`. The same certificate and private
key are used for inspirced and nginx.
Tasks
