ngIRCd - the "next generation" IRC daemon
ngircd [ Options ]
ngIRCd is a free, portable and lightweight Internet Relay Chat server
for small or private networks, developed under the GNU General Public
License (GPL). It is easy to configure, can cope with dynamic IP
addresses, and supports IPv6, SSL-protected connections as well as PAM
for authentication. It is written from scratch and not based on the
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 :-)
Currently supported platforms include AIX, A/UX, FreeBSD, HP-UX, Hurd,
IRIX, Linux, Mac OS X, Minix, NetBSD, OpenBSD, Solaris, and Windows
with Cygwin. As ngIRCd relies on UNIX standards and uses GNU automake
and GNU autoconf there are good chances that it also supports other
UNIX-based operating systems as well.
By default ngIRCd logs diagnostic and informational messages using the
syslog mechanism, or writes directly to the console when running in the
foreground (see below).
The default behavior of ngircd is to read its standard configuration
file (see below), to detach from the controlling terminal and to wait
You can use these options to modify this default:
-f file, --config file
Use file as configuration file.
Don't fork a child and don't detach from controlling terminal.
All log messages go to the console and you can use CTRL-C to
terminate the server.
Disable automatic connections to other servers. You can use the
IRC command CONNECT later on as IRC Operator to link this ngIRCd
to other servers.
Read, validate and display the configuration; then exit.
Output version information and exit.
Display a brief help text and exit.
The system wide default configuration file.
Default "message of the day" (MOTD).
The daemon understands the following signals:
TERM Shut down all connections and terminate the daemon.
HUP Shut down all listening sockets, re-read the configuration file
and re-initialize the daemon.
It's wise to use "ngircd --configtest" to validate the configuration
file after changing it.
When ngIRCd is compiled with debug code, that is, its source code has
been ./configure'd with "--enable-debug" and/or "--enable-sniffer"
(witch enables debug mode automatically as well), you can use two more
command line options and two more signals to debug problems with the
daemon itself or IRC clients:
Enable debug mode and log extra messages.
Enable IRC protocol sniffer, which logs all sent and received
IRC commands to the console/syslog. This option requires that
ngIRCd has been ./configure'd with "--enable-sniffer" and
enables debug mode automatically, too.
USR1 Toggle debug mode on and off during runtime.
USR2 Dump internal server state to the console/syslog when debug mode
is on (use command line option --debug or signal USR1).
