This is a text-only version of the following page on https://raymii.org: --- Title : Install the latest ZNC from source on Ubuntu Author : Remy van Elst Date : 25-10-2013 URL : https://raymii.org/s/tutorials/Install_the_Lastest_ZNC_from_Source_in_Ubuntu.html Format : Markdown/HTML --- This tutorial will show you how to install the latest (1.0) version of ZNC (an advanced IRC bouncer) on Ubuntu from source. Why from source? The package in the repositories is quite old and missing features like multiple IRC networks. It also includes an upstart script, and an example config for ZNC. ZNC is an advanced IRC bouncer that is left connected so an IRC client can disconnect/reconnect without losing the chat session.

This is tested on Ubuntu 12.04 and 13.10. It will probably work on debian, only you will have to use an init script instead of an upstart script. ### Note about checkinstall and packages We are using checkinstall here to create a debian package of the source we compile. I do this because it gives more flexibility in managing the software afterwards. Upgrading or uninstalling the packages is easier than removing all the things make install placed. Furthermore, it makes it more clear for other administrators which software is installed. If you for example want to upgrade znc when it was installed via this tutorial with checkinstall, repeat the tutorial with only the version number changed. ### Install required packages We first need to make sure we have all the packages required to build ZNC. Install them via apt: sudo apt-get install build-essential libssl-dev libperl-dev pkg-config checkinstall ### Compile ZNC Now we are going to get and compile ZNC itself. First download the source code: cd /usr/local/src sudo wget http://znc.in/releases/znc-latest.tar.gz Extract it and move into the folder: sudo tar -xzvf znc-latest.tar.gz cd znc* Start the actual compilation: ./configure make checkinstall For checkinstall, the default answers to the questions are good. ### ZNC User Create a separate ZNC user so that ZNC does not need to run as root: sudo groupadd znc sudo adduser --system --home /var/lib/znc --group znc ### Configuring ZNC You can use the interactive wizard to configure ZNC. I advise you to do this, it helps a lot when creating the initial configuration file: sudo -u znc /usr/local/bin/znc --datadir=/var/lib/znc --makeconf You can find my example config at the bottom of the tutorial. ### Upstart script Place the following script in `/etc/init/znc.conf` to be able to start and stop znc as a system service: # znc description "IRC Bouncer" start on runlevel [2345] stop on runlevel [016] respawn respawn limit 10 5 setuid znc script exec /usr/local/bin/znc --datadir=/var/lib/znc -f end script Save it, then you can start and stop znc like so: sudo start znc sudo stop znc ### Example ZNC configuration This is an example ZNC configuration file. You can place this in `/var/lib/znc/configs/znc.conf`. Make sure to stop ZNC first: // WARNING // // Do NOT edit this file while ZNC is running! // Use webadmin or *controlpanel instead. // // Buf if you feel risky, you might want to read help on /znc saveconfig and /znc rehash. // Also check http://en.znc.in/wiki/Configuration AnonIPLimit = 10 ConnectDelay = 5 LoadModule = partyline MaxBufferSize = 500 ProtectWebSessions = true SSLCertFile = /var/lib/znc/znc.pem ServerThrottle = 30 Version = 1.0 <Listener listener0> AllowIRC = true AllowWeb = false IPv4 = true IPv6 = true Port = 6667 SSL = true </Listener> <User Example> Admin = true AltNick = Example_ AppendTimestamp = false AutoClearChanBuffer = false Buffer = 500 ChanModes = +stn DenyLoadMod = false DenySetBindHost = false Ident = Example JoinTries = 10 LoadModule = chansaver LoadModule = controlpanel LoadModule = perform MaxNetworks = 3 MultiClients = true Nick = Example PrependTimestamp = true QuitMsg = So long and thanks for all the fish!
