ngircd(8) ngIRCd Manual ngircd(8) NAME ngIRCd - the "next generation" IRC daemon SYNOPSIS ngircd [ Options ] DESCRIPTION ngIRCd is a free, portable and lightweight Internet Relay Chat (IRC) server for small or private networks, developed under the GNU General Public Li- cense (GPL). The server is quite easy to configure and runs as a single-node server or can be part of a network of ngIRCd servers in a LAN or across the internet. It optionally supports the IPv6 protocol, SSL/TLS-protected client-server and server-server links, the Pluggable Authentication Modules (PAM) system for user authentication, IDENT requests, and character set conversion for legacy clients. The name ngIRCd stands for next-generation IRC daemon, which is a little bit exaggerated: lightweight Internet Relay Chat server most probably would have been a better name :-) By default ngIRCd logs diagnostic and informational messages using the sys- log mechanism, or writes directly to the console when running in the fore- ground (see below). OPTIONS The default behavior of ngircd is to read its standard configuration file (see below), to detach from the controlling terminal and to wait for clients. You can use these options to modify this default: -f file, --config file Use file as configuration file. -n, --nodaemon 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. -p, --passive 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. -y, --syslog Write log messages to the syslog even when running in the fore- ground. This only makes sense when -n/--nodaemon was given on the command line before this option! The following options prevent ngIRCd from starting regularly, but perform a specific action and then exit the daemon again: -h, --help Display a brief help text and exit. -t, --configtest Read, validate and display the configuration; then exit. -V, --version Output version information and exit. FILES /usr/local/etc/ngircd/ngircd.conf The system wide default configuration file. /usr/local/etc/ngircd/ngircd.motd Default "message of the day" (MOTD). SIGNALS 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. HINTS It is always wise to use "ngircd --configtest" to validate the configura- tion of ngIRCd after making changes to the configuration files! DEBUGGING ngIRCd can log additional debug messages, which can be enabled with the command line option --debug (-d) or by sending the USR1 signal to the run- ning daemon. Some of those messages may leak personal information, be very technical and can be very verbose. Therefore the debug mode is meant for troubleshooting only and should definitely be disabled during normal opera- tion! In addition, a "protocol sniffer" can be enabled on build time by passing the "--enable-sniffer" option to the ./configure script which enables the "--sniffer" (-s) command line option (which is not available by default): this "sniffer" logs all incoming and outgoing IRC commands on all connec- tions, which can be handy to debug problems with the daemon itself or IRC clients. Both modes are indicated in the version string shown by the IRC "VERSION" command: if the version ends in a dot (like in "26.1."), the daemon oper- ates in "normal" mode (the version used in the example is "26.1"). If it ends in ".1" (like in "26.1.1") the "debug-mode" is enabled; and if it ends in ".2" (like in "26.1.2") the "IRC sniffer" is enabled, too. Options: -d, --debug Enable debug mode and log extra messages. -s, --sniffer 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. Signals: Note: Usage of these signals is broadcasted to all users with the +s ("re- ceive server notices") mode set! 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).
