There are several possibilities to install ZNC on your machine. The latest version is always available using the source tarball from Sourceforge. Some distributions already include ZNC in their packaging system, but be aware that these may contain old versions of ZNC!

A ChangeLog is available in the wiki. You can also read more about ZNC's portability.

Once you have installed ZNC, you can create a config file with znc --makeconf.

Development Versions

Read the git page if you want to get the current development version. Beware that this might have more bugs, be a little unstable and eat your first born. You have been warned!

Source Tarball

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.

  1. Download the latest source tarball
  2. tar -xzvf znc*.*gz
  3. cd znc*
  4. ./configure
    (use --prefix=$HOME/znc if you don't want a system wide installation or simply don't have root; use --with-openssl=/path/to/openssl if you have a non-standard SSL path)
    (use --enable-extra to configure (and additionally --enable-tcl for modtcl) to include the whole extra package)
  5. make
    (if you are on a dedicated server and your CPU has more than one core, you can use make -jX where X is the number of CPU cores to speed up compilation)
  6. make install

Please note that compiling can take 5-10mins or more.

See the FAQ page if you encounter problems.



Debian provides ZNC packages which may be installed using:

apt-get install znc

Warning: Debian Stable has very old version by default. If you want newer version, use or compile znc from source.

If you want to build znc from source to get a newer version than Debian provides, you may need the following packages:


To include c-ares support, also install:



Fedora provides ZNC packages which may be installed using

yum install znc


yum install znc-extra

CentOS/Red Hat Enterprise Linux

ZNC packages are available in the Extra Packages for Enterprise Linux repository (EPEL).

To install the EPEL repository, execute:

rpm -Uvh
yum update

Once you have EPEL installed, execute:

yum install znc znc-extra


Ubuntu's ZNC packages

If you want to build znc from source to get a newer version than Ubuntu provides, you need the following packages:



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

To install ZNC-Extra and modtcl you need to install znc using:

USE="extras tcl" emerge znc

Several USE Flags can be used for znc:

  • ares: (global/local): enables using the c-ares libary
  • debug: (global): enable debug
  • extras: (global/local): enable additional modules
  • ipv6: global): adds support for ipv6
  • perl (global): adds support writing perl modules
  • ssl (global): enable secure socket layer connections
  • sasl (global): sasl support
  • tcl (global): adds support for writing tcl modules
equery uses znc -a

Will print you a list of USE flags that will be used for znc


Latest Slackware SBo Slackbuild


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

You may also be interested in rc.d scripts for znc which can be installed with:

pacman -U

You can read more about these scripts here


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:
  1. Make sure that you're using the --disable-perl switch for configure. Hence: ./configure --prefix=/usr/local --disable-perl
  2. If this still doesn't work, fetch and compile c-ares from source.


Installing Homebrew

For more information about Homebrew see here. The following command will install Homebrew to /usr/local

 ruby -e "$(curl -fsSLk"

Homebrew requires Xcode and Mac OS X >= 10.5

Installing znc with Homebrew

 brew install znc

Installing znc with MacPorts

 port install znc

Unofficial, user contributed binaries

The following installation sources are created and maintained by users!


Veit Wahlich created RPM packages and yum repositories for RedHat-based Linux distributions (RHEL/CentOS and Fedora). Version 0.052 is available at

Microsoft Windows

ZNC as a native Windows program, compiled with Microsoft Visual C++ Includes the main program and around 40 modules. Supports SSL and IPv6.
