:compact-option:
|
|
|
|
The unethical IRC trinity. This project consists of an experimental IRC client,
|
|
daemon, and bot. It's all you're ever going to need for chatting, as long as
|
|
you can make do with minimalist software.
|
|
|
|
All of them have these potentially interesting properties:
|
|
|
|
- full IPv6 support
|
|
- TLS support, including client certificates
|
|
- lean on dependencies (with the exception of 'degesch')
|
|
- compact and arguably easy to hack on
|
|
- permissive license
|
|
|
|
degesch
|
|
-------
|
|
The IRC client. It is largely defined by being built on top of GNU Readline
|
|
that has been hacked to death. Its interface should feel somewhat familiar for
|
|
weechat or irssi users.
|
|
|
|
This is the largest application within the project. It has most of the stuff
|
|
you'd expect of an IRC client, such as being able to set up multiple servers,
|
|
a powerful configuration system, integrated help, text formatting, CTCP queries,
|
|
automatic splitting of overlong messages, autocomplete, logging to file,
|
|
auto-away, command aliases and rudimentary support for Lua scripting.
|
|
|
|
kike
|
|
----
|
|
The IRC daemon. It is designed to be used as a regular user application rather
|
|
than a system-wide daemon. If all you want is a decent, minimal IRCd for
|
|
testing purposes or a small network of respectful users (or bots), this one will
|
|
do it just fine.
|
|
|
|
Notable features:
|
|
|
|
- TLS autodetection (why doesn't everyone have this?), using secure defaults
|
|
- IRCop authentication via TLS client certificates
|
|
- epoll/kqueue support; this means that it should be able to handle quite
|
|
a number of concurrent user connections
|
|
- partial IRCv3 support
|
|
|
|
Not supported:
|
|
|
|
- server linking (which also means no services); I consider existing protocols
|
|
for this purpose ugly and tricky to implement correctly; I've also found no
|
|
use for this feature yet
|
|
- online changes to configuration; the configuration system from degesch could
|
|
be used to implement this feature if needed
|
|
- limits of almost any kind, just connections and mode `+l`
|
|
|
|
ZyklonB
|
|
-------
|
|
The IRC bot. It builds upon the concept of my other VitaminA IRC bot. The main
|
|
characteristic of these two bots is that they run plugins as coprocesses, which
|
|
allows for enhanced reliability and programming language freedom.
|
|
|
|
While originally intended to be a simple rewrite of the original AWK bot in C,
|
|
it fairly quickly became a playground, and it eventually got me into writing
|
|
the rest of the package.
|
|
|
|
It survives crashes, server disconnects and timeouts, and also has native SOCKS
|
|
support (even though socksify can add that easily to any program).
|
|
|
|
Packages
|
|
--------
|
|
Regular releases are sporadic. git master should be stable enough. You can get
|
|
a package with the latest development version from Archlinux's AUR, or from
|
|
openSUSE Build Service for the rest of mainstream distributions. Consult the
|
|
list of repositories and their respective links at:
|
|
|
|
https://build.opensuse.org/project/repositories/home:pjanouch:git
|
|
|
|
Building
|
|
--------
|
|
Build dependencies: CMake, pkg-config, help2man, awk, sh, liberty (included) +
|
|
Runtime dependencies: openssl +
|
|
Additionally for degesch: curses, libffi, lua >= 5.3 (optional),
|
|
readline >= 6.0 or libedit >= 2013-07-12
|
|
|
|
$ git clone --recursive https://github.com/pjanouch/uirc3.git
|
|
$ mkdir uirc3/build
|
|
$ cd uirc3/build
|
|
$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug \
|
|
-DWANT_READLINE=ON -DWANT_LIBEDIT=OFF -DWANT_LUA=ON
|
|
$ make
|
|
|
|
To install the application, you can do either the usual:
|
|
|
|
# make install
|
|
|
|
Or you can try telling CMake to make a package for you. For Debian it is:
|
|
|
|
$ cpack -G DEB
|
|
# dpkg -i uirc3-*.deb
|
|
|
|
Usage
|
|
-----
|
|
'degesch' has in-program configuration. Just run it and read the instructions.
|
|
|
|
For the rest you might want to generate a configuration file:
|
|
|
|
$ zyklonb --write-default-config
|
|
$ kike --write-default-config
|
|
|
|
After making any necessary edits to the file (there are comments to aid you in
|
|
doing that), simply run the appropriate program with no arguments:
|
|
|
|
$ zyklonb
|
|
$ kike
|
|
|
|
'ZyklonB' stays running in the foreground, therefore I recommend launching it
|
|
inside a Screen or tmux session.
|
|
|
|
'kike', on the other hand, immediately forks into the background. Use the PID
|
|
file or something like `killall` if you want to terminate it. You can run it
|
|
as a `forking` type systemd user service.
|
|
|
|
Client Certificates
|
|
-------------------
|
|
'kike' uses SHA1 fingerprints of TLS client certificates to authenticate users.
|
|
To get the fingerprint from a certificate file in the required form, use:
|
|
|
|
$ openssl x509 -in public.pem -outform DER | sha1sum
|
|
|
|
Custom Key Bindings in degesch
|
|
------------------------------
|
|
The default and preferred frontend used in 'degesch' is GNU Readline. This
|
|
means that you can change your bindings by editing '~/.inputrc'. For example:
|
|
....
|
|
# Preload with system-wide settings
|
|
$include /etc/inputrc
|
|
|
|
# Make M-left and M-right reorder buffers
|
|
$if degesch
|
|
"\e\e[C": move-buffer-right
|
|
"\e\e[D": move-buffer-left
|
|
$endif
|
|
....
|
|
Consult the source code and the GNU Readline manual for a list of available
|
|
functions. Also refer to the latter for the exact syntax of this file.
|
|
Beware that you can easily break the program if you're not careful.
