I. Upgrade Information
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Differences to version 16
|
|
|
|
- Changes to the "MotdFile" specified in ngircd.conf now require a ngircd
|
|
configuration reload to take effect (HUP signal, REHASH command).
|
|
|
|
Differences to version 0.9.x
|
|
|
|
- The option of the configure script to enable support for Zeroconf/Bonjour/
|
|
Rendezvous/WhateverItIsNamedToday has been renamed:
|
|
--with-rendezvous -> --with-zeroconf
|
|
|
|
Differences to version 0.8.x
|
|
|
|
- The maximum length of passwords has been raised to 20 characters (instead
|
|
of 8 characters). If your passwords are longer than 8 characters then they
|
|
are cut at an other position now.
|
|
|
|
Differences to version 0.6.x
|
|
|
|
- Some options of the configure script have been renamed:
|
|
--disable-syslog -> --without-syslog
|
|
--disable-zlib -> --without-zlib
|
|
Please call "./configure --help" to review the full list of options!
|
|
|
|
Differences to version 0.5.x
|
|
|
|
- Starting with version 0.6.0, other servers are identified using asynchronous
|
|
passwords: therefore the variable "Password" in [Server]-sections has been
|
|
replaced by "MyPassword" and "PeerPassword".
|
|
|
|
- New configuration variables, section [Global]: MaxConnections, MaxJoins
|
|
(see example configuration file "doc/sample-ngircd.conf"!).
|
|
|
|
|
|
II. Standard Installation
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
ngIRCd is developed for UNIX-based systems, which means that the installation
|
|
on modern UNIX-like systems that are supported by GNU autoconf and GNU
|
|
automake ("configure") should be no problem.
|
|
|
|
The normal installation procedure after getting (and expanding) the source
|
|
files (using a distribution archive or GIT) is as following:
|
|
|
|
1) ./autogen.sh [only necessary when using GIT]
|
|
2) ./configure
|
|
3) make
|
|
4) make install
|
|
|
|
(Please see details below!)
|
|
|
|
Now the newly compiled executable "ngircd" is installed in its standard
|
|
location, /usr/local/sbin/.
|
|
|
|
The next step is to configure and afterwards starting the daemon. Please
|
|
have a look at the ngircd(8) and ngircd.conf(5) manual pages for details
|
|
and all possible options.
|
|
|
|
If no previous version of the configuration file exists (the standard name
|
|
is /usr/local/etc/ngircd.conf), a sample configuration file containing all
|
|
possible options will be installed there. You'll find its template in the
|
|
doc/ directory: sample-ngircd.conf.
|
|
|
|
|
|
1): "autogen.sh"
|
|
|
|
The first step, autogen.sh, is only necessary if the configure-script isn't
|
|
already generated. This never happens in official ("stable") releases in
|
|
tar.gz-archives, but when using GIT.
|
|
|
|
This step is therefore only interesting for developers.
|
|
|
|
autogen.sh produces the Makefile.in's, which are necessary for the configure
|
|
script itself, and some more files for make. To run autogen.sh you'll need
|
|
GNU autoconf and GNU automake (use recent versions! autoconf 2.53 and
|
|
automake 1.6.1 are known to work).
|
|
|
|
Again: "end users" do not need this step!
|
|
|
|
|
|
2): "./configure"
|
|
|
|
The configure-script is used to detect local system dependencies.
|
|
|
|
In the perfect case, configure should recognise all needed libraries, header
|
|
files and so on. If this shouldn't work, "./configure --help" shows all
|
|
possible options.
|
|
|
|
In addition, you can pass some command line options to "configure" to enable
|
|
and/or disable some features of ngIRCd. All these options are shown using
|
|
"./configure --help", too.
|
|
|
|
Compiling a static binary will avoid you the hassle of feeding a chroot dir
|
|
(if you want use the chroot feature). Just do something like:
|
|
CFLAGS=-static ./configure [--your-options ...]
|
|
Then you can use a void directory as ChrootDir (like OpenSSH's /var/empty).
|
|
|
|
|
|
3): "make"
|
|
|
|
The make command uses the Makefiles produced by configure and compiles the
|
|
ngIRCd daemon.
|
|
|
|
|
|
4): "make install"
|
|
|
|
Use "make install" to install the server and a sample configuration file on
|
|
the local system. Normally, root privileges are necessary to complete this
|
|
step. If there is already an older configuration file present, it won't be
|
|
overwritten.
|
|
|
|
This files will be installed by default:
|
|
|
|
- /usr/local/sbin/ngircd: executable server
|
|
- /usr/local/etc/ngircd.conf: sample configuration (if not already present)
|
|
- /usr/local/share/doc/ngircd/: documentation
|
|
|
|
|
|
III. Additional features
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The following optional features can be compiled into the daemon by passing
|
|
options to the "configure" script. Most options can handle a <path> argument
|
|
which will be used to search for the required libraries and header files in
|
|
the given paths ("<path>/lib/...", "<path>/include/...") in addition to the
|
|
standard locations.
|
|
|
|
* Syslog Logging (autodetected by default):
|
|
--with-syslog[=<path>] / --without-syslog
|
|
|
|
Enable (disable) support for logging to "syslog", which should be
|
|
available on most modern UNIX-like operating systems by default.
|
|
|
|
* ZLib Compression (autodetected by default):
|
|
--with-zlib[=<path>] / --without-zlib
|
|
|
|
Enable (disable) support for compressed server-server links.
|
|
The Z compression library ("libz") is required for this option.
|
|
|
|
* IO Backend (autodetected by default):
|
|
--with-select[=<path>] / --without-select
|
|
--with-poll[=<path>] / --without-poll
|
|
--with-devpoll[=<path>] / --without-devpoll
|
|
--with-epoll[=<path>] / --without-epoll
|
|
--with-kqueue[=<path>] / --without-kqueue
|
|
|
|
ngIRCd can use different IO "backends": the "old school" select() and poll()
|
|
API which should be supported by most UNIX-like operating systems, or the
|
|
more efficient and flexible epoll() (Linux >=2.6), kqueue() (BSD) and
|
|
/dev/poll APIs.
|
|
By default the IO backend is autodetected, but you can use "--without-xxx"
|
|
to disable a more enhanced API.
|
|
When using the epoll() API, support for select() is compiled in as well by
|
|
default to enable the binary to run on older Linux kernels (<2.6), too.
|
|
|
|
* IDENT-Support:
|
|
--with-ident[=<path>]
|
|
|
|
Include support for IDENT ("AUTH") lookups. The "ident" library is
|
|
required for this option.
|
|
|
|
* ZeroConf Support:
|
|
--with-zeroconf[=<path>]
|
|
|
|
Compile ngIRCd with support for ZeroConf multicast DNS service registration.
|
|
Either the Apple ZeroConf implementation (e. g. Mac OS X) or the Howl
|
|
library is required. Which one is available is autodetected.
|
|
|
|
* TCP-Wrappers:
|
|
--with-tcp-wrappers[=<path>]
|
|
|
|
Include support for Wietse Venemas "TCP Wrappers" to limit client access
|
|
to the daemon, for example by using "/etc/hosts.{allow|deny}".
|
|
The "libwrap" is required for this option.
|
|
|
|
* PAM:
|
|
--with-pam[=<path>]
|
|
|
|
Enable support for PAM, the Pluggable Authentication Modules library.
|
|
See doc/PAM.txt for details.
|
|
|
|
* SSL:
|
|
--with-openssl[=<path>]
|
|
--with-gnutls[=<path>]
|
|
|
|
Enable support for SSL/TLS using OpenSSL or gnutls libraries.
|
|
See doc/SSL.txt for details.
|
|
|
|
* IPv6:
|
|
--enable-ipv6
|
|
|
|
Adds support for version 6 of the Internet Protocol.
|
|
|
|
|
|
IV. Useful make-targets
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The Makefile produced by the configure-script contains always these useful
|
|
targets:
|
|
|
|
- clean: delete every product from the compiler/linker
|
|
next step: -> make
|
|
|
|
- distclean: the above plus erase all generated Makefiles
|
|
next step: -> ./configure
|
|
|
|
- maintainer-clean: erase all automatic generated files
|
|
next step: -> ./autogen.sh
|
|
|
|
|
|
V. Sample configuration file ngircd.conf
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
In the sample configuration file, there are comments beginning with "#" OR
|
|
";" -- this is only for the better understanding of the file.
|
|
|
|
The file is separated in four blocks: [Global], [Operator], [Server], and
|
|
[Channel].
|
|
|
|
In the [Global] section, there is the main configuration like the server
|
|
name and the ports, on which the server should be listening. IRC operators
|
|
of this server are defined in [Operator] blocks. [Server] is the section
|
|
where server links are configured. And [Channel] blocks are used to
|
|
configure pre-defined ("persistent") IRC channels.
|
|
|
|
The meaning of the variables in the configuration file is explained in the
|
|
"doc/sample-ngircd.conf", which is used as sample configuration file in
|
|
/usr/local/etc after running "make install" (if you don't already have one)
|
|
and in the "ngircd.conf" manual page.
|
|
|
|
|
|
VI. Command line options
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
These parameters could be passed to the ngIRCd:
|
|
|
|
-f, --config <file>
|
|
The daemon uses the file <file> as configuration file rather than
|
|
the standard configuration /usr/local/etc/ngircd.conf.
|
|
|
|
-n, --nodaemon
|
|
ngIRCd should be running as a foreground process.
|
|
|
|
-p, --passive
|
|
Server-links won't be automatically established.
|
|
|
|
-t, --configtest
|
|
Reads, validates and dumps the configuration file as interpreted
|
|
by the server. Then exits.
|
|
|
|
Use "--help" to see a short help text describing all available parameters
|
|
the server understands, with "--version" the ngIRCd shows its version
|
|
number. In both cases the server exits after the output.
|
