ZNC install for network Administrators

This guide tells how we install ZNC for our whole network, with integrated login to our X3 services.

Install saslauthd

  • Install saslauthd package: apt-get install sasl2-bin
  • edit /etc/defaults/saslauthd:
START=yes
MECHANISM="ldap"
  • edit/create /etc/saslauthd.conf:
ldap_servers: ldaps://yourldapserver.domain
ldap_search_base: ou=Users,dc=yourdomain,dc=org
ldap_filter: (uid=%u)
#ldap_tls_cacert_file: /etc/ssl/yourcertificate.cer
  • Copy the CA certificate matching your ldap server to /etc/ssl/yourcertificate.cer if needed
  • start saslauthd: /etc/init.d/saslauthd start
  • Test saslauthd: testsaslauthd -u “yourldapuid” -p yourpassword -f /var/run/saslauthd/mux
  • Troubleshooting:
    • Stop saslauthd and run it in debug mode: /usr/sbin/saslauthd -a ldap -c -m /var/run/saslauthd -n 1 -d
    • check /var/log/auth.log and /var/log/daemon.log
    • try ldapsearch and see if that works: 
ldapsearch -D "uid=youruid,ou=Users,dc=yourdomain,dc=org" -w yourpassword -H ldaps://ldapservername -b "ou=Users,dc=yourdomain,dc=org" -s sub "(objectclass=*)"

Install ZNC

Assuming a debian 8 (jessie) base system:

  • Install debian backports: add deb http://ftp.debian.org/debian jessie-backports main to /etc/apt/sources.list. dont forget to sudo apt-get update
  • Install build dependencies by cheating a bit using the debian dependency list: sudo apt-get build-dep znc
  • Install CMake: sudo apt-get install cmake
  • Install ICU: sudo apt-get install libicu-dev
  • Install SWIG: sudo apt-get install swig3.0
  • Install Boost: sudo apt-get install libboost-all-dev
  • git clone the repository. We maintain some patches to ZNC for integration with sasl/ldap etc so you'll want to use the latest version branch from our znc fork: https://github.com/evilnet/znc
  • cd to the cloned repository
  • ./configure –prefix=/data/irc/services/znc –enable-cyrus –enable-python –enable-perl
  • enable git submodules: git submodule update –init –recursive
  • compile: make
  • install: make install

      • Create a dummy user in znc to use as a skel/clone identity
      • Set cyrusauth module to use it: /msg *cyrusauth cloneuser yourcloneusernamehere
      • Let it create users: /msg *cyrusauth createuser Yes
    • Load the sasl module: /msg *status load sasl
