ngIRCd - Internet Relay Chat Server


ngIRCd is a free, portable and lightweight Internet Relay Chat (IRC) server for small or private networks, developed under the terms of the GNU General Public License (GPL); please see the file COPYING for licensing information.

The server is quite easy to configure, can handle dynamic IP addresses, and optionally supports IDENT, IPv6 connections, SSL-protected links, and PAM for user authentication as well as character set conversion for legacy clients. The server has been written from scratch and is not based on the "forefather", the daemon of the IRCNet.

The name ngIRCd means next-generation IRC daemon, which is a little bit exaggerated: lightweight Internet Relay Chat server most probably would have been a better name :-)

Please see the document for installation and upgrade information, online available here:!


ngIRCd should be quite feature-complete and stable to be used as a daemon in real-world IRC networks.

It is not the goal of ngIRCd to implement all the nasty behaviors of the original ircd, but to implement most of the useful commands and semantics specified by the RFCs that are used by existing clients.
