Quassel

Introduction

Quassel is a program to connect to an IRC network. It has the unique ability to split the graphical component (quasselclient) from the part that handles the IRC connection (quasselcore). This means that you can have a remote core permanently connected to one or more IRC networks and attach a client from wherever you are without moving around any information or settings. However, Quassel can easily behave like any other client by combining them into one binary, which is referred to as "Quassel Mono".

Quassel's distributed approach:
Quassel's setup

Getting started

Setting up Quassel is fairly easy and straightforward. Since we have a separated core and client, we will configure them in two steps. If you are using the Quassel Mono version, then you can skip the core part as this is done internally.

Installation

The best and most reliable way is to simply install the packages provided by your distribution. However, we do offer some static binaries at http://quassel-irc.org/downloads along with Git instructions for those who prefer to compile Quassel themselves.

Connecting to the core

If you wish to setup an SSL connection between the core and client, you must have compiled both with the "-DWITH_OPENSSL=ON" cmake option. Generate a key with the following command on the server running the core:

Version before 0.4

openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout ~/.quassel/quasselCert.pem -out ~/.quassel/quasselCert.pem

The "~/.quassel/" directory may differ if the --datadir option was specified for quasselcore.

Version 0.4 and later

openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout ~/.config/quassel-irc.org/quasselCert.pem -out ~/.config/quassel-irc.org/quasselCert.pem

The default config directory has changed in version 0.4 and the core's --datadir option has been renamed to --configdir.

Note that Kubuntu packages for Jaunty (9.04) and later do this step for you.

If you wish to use the PostgreSQL database backend, you can follow the PostgreSQL article first before moving on.

Now start the core and launch quasselclient on your local machine. A connection dialog will show up. Enter the IP address or hostname of the server running the core, enter the port number used by the core and select SSL if applicable. You can also specify a proxy but note that domain names will still be resolved locally (see Qt4.4).

During the first connection, you will be guided through a graphical wizard to configure the core properly. Enter a username and password, this will be the administrator. Next, select a database backend (for now this is SQLite only). Click finish and your core is ready!

A configuration screen for adding new users and managing existing ones is under developement, but for the time being you can use a simple python script.

IRC Configuration

Now you have to specify which network(s) Quassel should connect to. First you will have to create an identity.

Creating an identity

Set a real name (which doesn't actually have to be real) and add the nicknames you want to use. If the first nickname is not available, the second one (if specified) will be used instead. Change the other settings if you like, this is optional however.

After creating an identity, you have to define the IRC network(s) along with the servers they use. If Quassel was installed properly, there should be a preconfigured list of the most popular networks already.

Configuring the IRC network

Make sure you select the identity you just created (which should be the default). Click OK and you're done. Feel free to visit us in the #quassel channel on Freenode!

Manuals

Known issues

  • DCC chat and file transfers are not yet supported.
  • The core does support multiple users but for now this can only be configured with a script.
  • There has been a client for mobile devices but as the codebase updated so quickly it has become outdated and incompatible with newer cores.
  • See Issues for specific bugs and feature requests.
  • FAQ

Static Builds

Shortcuts

  • If you want to change channels quickly, you can use CTRL+0-9 to assign a shortcut to the current channel. With ALT+0-9 its possible to jump to the channels accordingly.
