Kaoz is a free notifier for IRC. It's purpose is to provide an easy to use way for System Administrators to send warnings and logs on any choosen IRC channel. It therefore uses a persistent daemon, which is called the server later on, that will listen on a given port, optionnaly with ssl enabled. The server expects lines to have the format password:channel:message, like secret:#help:Hello. password is a global password required to use the service. channel is an irc channel on the configured network. (Kaoz will join the channel to do so). A client is an application which connects to the server to send messages on IRC. Please note that, in case you whish to agregate many servers' notifications, you may have only one Kaoz server, but you should multiply clients.
Kaoz is provided under a MIT-like licence. See the licence file for more informations.
- python ssl module (if you whish to use SSL)
- python irc library (https://bitbucket.org/jaraco/irc)
Installation of the server
First, copy the config to the location of your choice, for example /etc/kaoz.conf. Then edit the kaoz.conf file to provide correct values for the IRC Server and the listening socket. The daemon is started with the bin/kaoz program. There is a Gentoo init.d file in initd/kaoz for your interest. It should be easy to figure out how to adapt this file to your distribution.
- Kaoz does not support key-protected channels.
Kaoz client examples
Sending messages to IRC
Here are some ways to send Hello to channel #help using a Kaoz server which is listenning on host myhost port 4242, protected with password secret. For that purpose, a client needs to send secret:#help:Hello to the server (with an optional LF or CR+LF, as you want).
- In Shell, for simple servers without SSL, use one of the following lines:
echo "secret:#help:Hello" |netcat myhost 4242 echo "secret:#help:Hello" |socat - TCP:myhost:4242
- In Shell, for servers which use SSL certificates:
echo "secret:#help:Hello" |socat - OPENSSL:myhost:4242
- In Shell, for servers which use SSL certificates and a trusted authority certificate file (CA file):
echo "secret:#help:Hello" |socat - OPENSSL:myhost:4242,verify,cafile=myca.crt
- In Python without SSL:
import socket sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.connect(('myhost', 4242)) sock.sendall('%s:%s:%s' % ('secret', '#help', 'Hello')) sock.close()
- In Python with SSL:
import socket import ssl sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.connect(('myhost', 4242)) # use these options to check CA: cert_reqs=ssl.CERT_REQUIRED, certfile='myca.crt' sock = ssl.wrap_socket(self.sock) sock.sendall('%s:%s:%s' % ('secret', '#help', 'Hello')) sock.close()
Kaoz server support multi-lined messages, so long as each lines begins with the password and a channel.
Sending commands to Koaz
A Kaoz server also accepts basic commands which enable its monitoring. When a client wants to run command on the server, she needs to send secret::command and the server replies directly in the socket. The double colon that it is a command, rather than a message to send to IRC.
The following commands are supported (there is only one for the time being):
- channels: get the list of channels the server has joined.
About IRC style and colors
Some control sequences allow IRC users to write messages with style and colors (^X means Ctrl+X):
- ^B (= x02) Bold text
- ^C (= x03) Colored text
- ^O (= x0F) Back to original plain text
- ^R (= x16) Reversed text
- ^_ (= x1F) Underlined text
There are 16 colors:
- Navy Blue
- Lime Green
- Aqua Light
- Royal Blue
- Hot Pink
- Dark Gray
- Light Gray
For example ^C2Hello writes Hello in blue.
