There are several possibilities to install ZNC on your machine. The latest version is always available using the source tarball from http://znc.in/releases.
There are known exploits in all versions under 1.2! It is highly recommended that you install from the source tarball!
- Which way should I choose for installing ZNC?
- If you don't have root access, the only way is to use source tarball. You'll need to use
./configure --prefix=$HOME/zncas described.
- If you have root access, you can use either source tarball or the convenient way for your distro. Check section about your distro for details, but be aware that these may contain old versions of ZNC!
Once you have installed ZNC, you can create a config file with
- 1 Development Versions
- 2 Source Tarball
- 3 Linux
- 4 FreeBSD
- 5 Mac OS X
- 6 Cygwin
- 7 Unofficial, user contributed binaries
Read the git page if you want to get the current development version. Beware that this might have more bugs, more features, be a little unstable and eat your first born. You have been warned!
Official source tarballs can be found here.
If you want to compile ZNC with OpenSSL support, you need the OpenSSL development package. On Debian/Ubuntu this is called libssl-dev, on CentOS/Fedora/Red Hat it's openssl-devel.
- Download the latest source tarball
tar -xzvf znc*.*gz
--prefix=$HOME/zncif you don't want a system wide installation or simply don't have root access; use
--with-openssl=/path/to/opensslif you have a non-standard SSL path)
--helpto see other configure options)
(if you are on a dedicated server and your CPU has more than one core, you can use
make -jXwhere X is the number of CPU cores to speed up compilation)
Please note that compiling can take 5-10mins or more.
Once you have installed znc, you can use
znc --makeconf to make a configuration file for ZNC. This config is stored in ~/.znc under the user you run it as. You should create a dedicated non root user to run znc under.
ZNC is run by just executing znc under the dedicated znc user, at which stage it goes to background. It does not make an init.d service for itself nor does it need to be run in screen or something similar.
- See the FAQ page if you encounter problems.
Debian provides ZNC packages which may be installed using:
aptitude install znc
If you want to build znc from source to get a newer version than Debian provides, you may need the following packages:
build-essential libssl-dev libperl-dev
You can use the command
aptitude build-dep znc
to install build dependencies automatically. Note that sometimes these build-depedencies are outdated and won't work with the current version of ZNC.
Fedora provides ZNC packages which may be installed using
yum install znc
CentOS/Red Hat Enterprise Linux
ZNC packages are available in the Extra Packages for Enterprise Linux repository (EPEL).
To install the EPEL repository, lookup the appropriate EPEL package at http://mirrors.fedoraproject.org/publiclist/EPEL/ then execute the following commands:
rpm -Uvh <link to your package name/architecture>/epel-release-5-4.noarch.rpm yum update
Once you have EPEL installed, execute:
yum install znc znc-extra
If you want to build znc from source to get a newer version than Ubuntu provides, you need the following packages:
build-essential libssl-dev libperl-dev pkg-config
You can also run the command
sudo apt-get build-dep znc
if you want to get the build dependencies installed automatically.
ZNC 1.0 was backported to Ubuntu Precise (12.04). To install it, run the following from the command line:
sudo apt-get install znc/precise-backports znc-dbg/precise-backports znc-dev/precise-backports znc-extra/precise-backports znc-perl/precise-backports znc-python/precise-backports znc-tcl/precise-backports
ZNC 1.0 was backported to Ubuntu Quantal (12.10). To install it, run the following from the command line:
sudo apt-get install znc/quantal-backports znc-dbg/quantal-backports znc-dev/quantal-backports znc-extra/quantal-backports znc-perl/quantal-backports znc-python/quantal-backports znc-tcl/quantal-backports
ZNC is part of the official repositories. To install, use the YaST GUI or install via commandline by typing
yast -i znc
Gentoo provides ZNC packages which may be installed using:
emerge -av net-irc/znc
Several USE Flags can be used for znc:
- ares (global/local): enables using the c-ares library (for stable versions predating 1.0 only; deprecated in favor of dns-threads)
- debug (global): enable debug
- dns-threads (local): use threads for DNS resolving (for v1.0)
- extras (global/local): enable additional modules
- ipv6 (global): adds support for ipv6
- perl (global): adds support for writing perl modules
- python (global): adds support for writing python 3 modules
- ssl (global): enable secure socket layer connections
- sasl (global): sasl support
- tcl (global): adds support for writing tcl modules
equery uses znc -aWill print you a list of USE flags that will be used for znc
To install znc from the package manager, enter the following command:
sudo apk add znc znc-modperl znc-modtcl
If you want to build znc from source to get a newer version than Alpine provides, you need to install packages with the following command:
sudo apk add autoconf automake gettext-dev g++ make openssl-dev pkgconfig zlib-dev
sudo apk add git gdb perl-dev swig tcl-dev cyrus-sasl-dev
Note: Python3 does not exist in Alpine.
ZNC is part of the archlinux package repository, and can be installed with the following:
pacman -S znc
Additionally you can install the following optional dependencies to add support for additional modules.
- cyrus-sasl - saslauth module
- perl - modperl module
- python - modpython module
- tcl - modtcl module
rc.d scripts (deprecated)
You may also be interested in rc.d scripts for znc which can be installed with:
You can read more about these scripts here. As of November 2012, initscripts support is being phased-out and expected to be totally deprecated in early 2013. Systemd scripts are already distributed in the package. The Archlinux wiki has some helpful information for new users who are getting started with znc.
You can install the latest git snapshot from the Arch User Repository.
ZNC is in FreeBSD ports, just do:
cd /usr/ports/irc/znc make config make install clean
pkg_add -r znc
Mac OS X
There are two ways to install ZNC on OS X, either using a package manager such as Homebrew or installing it yourself from source. See this blog post for a tutorial on how to compile ZNC from source.
- NOTE: If you are running on PPC architecture and cannot make the ./configure && make && sudo make install dance work, you'll want to do the following:
- Make sure that you're using the --disable-perl switch for configure. Hence: ./configure --prefix=/usr/local --disable-perl
For more information about Homebrew see here. The following command will install Homebrew to /usr/local
ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"
Homebrew requires Xcode and Mac OS X >= 10.5
Installing znc with Homebrew
brew install znc
Installing znc with MacPorts
port install znc
Download Cygwin, and install. In the setup, do a search for the following packages and install them:
Getting the ZNC source code:
automake gcc-g++ make mpfr pkg-config openssl-devel zlib-devel
