.TH ngircd 8 "Jan 2021" ngIRCd "ngIRCd Manual"
.SH NAME
ngIRCd \- the "next generation" IRC daemon
.SH SYNOPSIS
.B ngircd
[
.I Options
]
.SH DESCRIPTION
.BR ngIRCd
is a free, portable and lightweight Internet Relay Chat server for small
or private networks, developed under the GNU General Public License (GPL).
.PP
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.
.PP
The name ngIRCd means
.IR "next-generation IRC daemon",
which is a little bit exaggerated:
.IR "lightweight Internet Relay Chat server"
most probably would have been a better name :-)
.PP
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.
.PP
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).
.SH OPTIONS
The default behavior of
.BR ngircd
is to read its standard configuration file (see below), to detach from the
controlling terminal and to wait for clients.
.PP
You can use these options to modify this default:
.TP
\fB\-f\fR \fIfile\fR, \fB\-\-config\fR \fIfile\fR
Use
.I file
as configuration file.
.TP
\fB\-n\fR, \fB\-\-nodaemon\fR
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.
.TP
\fB\-p\fR, \fB\-\-passive\fR
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.
.TP
\fB\-t\fR, \fB\-\-configtest\fR
Read, validate and display the configuration; then exit.
.TP
\fB\-V\fR, \fB\-\-version\fR
Output version information and exit.
.TP
\fB\-h\fR, \fB\-\-help\fR
Display a brief help text and exit.
.SH FILES
.I :ETCDIR:/ngircd.conf
.RS
The system wide default configuration file.
.RE
.I :ETCDIR:/ngircd.motd
.RS
Default "message of the day" (MOTD).
.RE
.SH SIGNALS
The daemon understands the following signals:
.TP
\fBTERM\fR
Shut down all connections and terminate the daemon.
.TP
\fBHUP\fR
Shut down all listening sockets, re-read the configuration file and
re-initialize the daemon.
.SH HINTS
It's wise to use "ngircd \-\-configtest" to validate the configuration file
after changing it.
.SH DEBUGGING
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:
.PP
\fBOptions:\fR
.TP
\fB\-d\fR, \fB\-\-debug\fR
Enable debug mode and log extra messages.
.TP
\fB\-s\fR, \fB\-\-sniffer\fR
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.
.PP
\fBSignals:\fR
.TP
\fBUSR1\fR
Toggle debug mode on and off during runtime.
.TP
\fBUSR2\fR
Dump internal server state to the console/syslog when debug mode is on (use
command line option \-\-debug or signal USR1).
