NeoIRCd INSTALL Document +------------------------------------------------------------------------+ | Note for those who dont bother reading docs | | | | Reading INSTALL is now a must, as the old DPATH is now specified when | | configure is run. | | | | - You now need to ./configure --prefix="/path/to/install/it" | | | +------------------------------------------------------------------------+ HOW TO BUILD 1. Read the ChangeLog file to find out about the exciting new features in this version. Other good reads are doc/whats-new.txt, BUGS, doc/example.conf, and README.FIRST. 2. Run the configure script. It will create include/setup.h and the Makefiles to match your system. In NeoIRCd, the paths are set with the --prefix option to configure, not in config.h. /usr/local/ircd is the default if no prefix is specified. ./configure --prefix="/usr/local/ircd" Note: There are some special optional parameters to the configure script that some admins may wish to use. * --enable-kqueue - Use the superior kqueue(2) system call as opposed to the default poll(2). This is currently only available on FreeBSD 4.1 or higher. * --enable-devpoll - Enable the superior /dev/poll support on Solaris. Linux /dev/poll is broken and will not work with this option. * --enable-rtsigio - Enable the superior Linux RealTime Signal I/O system. This is currently only available on 2.4 Linux kernel versions or later. * --enable-openssl - Enable the openssl dependent crypto functions. This will allow CHALLENGE to work and encrypted links. On systems where the configure script can automatically detect OpenSSL, this option is not necessary. If configure cannot find OpenSSL, you must specify a path with this option (--enable-openssl=/path/to/openssl) * --enable-ipv6 - Enable IPv6 support. * --disable-shared-modules - Disable module support. This option is more secure, but reduces a lot of the flexibility in NeoIRCd 7. This may need to be used on some systems without a working dl library. * --disable-assert - Disable some of the debugging code. This should be used on all production servers for maximum speed and to prevent cores from things that shouldn't normally happen. * --enable-small-net - Tunes the server for smaller networks by reducing the startup memory footprint. This should really only be used for *small* networks, as this tends to be a performance hit on larger networks. * --with-maxclients - Sets the maximum number of clients support by the server. Note that this also twiddles the HARD_FDLIMIT_ define so it is no longer necessary to modify include/config.h for this. If HARD_FDLIMIT_ ends up being larger that FD_SETSIZE when using select() for your I/O loop, s_bsd_select.c will refuse to compile (and tell you to use poll instead). Take this error's advice and use --enable-poll or something a bit more efficient. You'll be happier at the end of the day for it. 3. Look over the "include/config.h" file. This allows you to change the few remaining hard coded options of how the ircd will operate. Most admins will only have to change a few settings. USE_SYSLOG is the only one that most admins will need to edit. Note: Note that you must have permission by the sysadmin to send messages to the system log files. All other settings in config.h are not necessary to edit. 4. make should build ircd. 5. make install will install the server, modules(1), and tools in the path defined in config.h and the prefix specified when configure was run. (1) Unless the server was compiled without module support. 6. If you wish to enable the user log, oper log, and failed oper log, issue these commands at the shell prompt (in the prefix directory) $ touch logs/userlog $ touch logs/operlog $ touch logs/foperlog Note: If you use different names in ircd.conf, you must 'touch' the specific names. ---------------------------------------------------------------------- HOW TO GET HELP Visit http://www.neostats.net/boards/ or you can see if anyone is awake in irc://irc.irc-chat.org/#neostats We do have a email address, but you will tend to get a quicker response from posting your messages on our boards. You should also check previous posts on the boards as someone might have already answered your questions. ---------------------------------------------------------------------- NOTES The best way to get a backtrace of the core is to follow this sequence of instructions: 1. Change to the directory containing the core file 2. Run gdb on the binary and the core file. With an unmodified NeoIRCd-7 installation, an example command line is below (in the /usr/local/ircd directory) $ gdb bin/ircd ircd.core 3. At the "(gdb)" prompt, enter the command "bt" 4. Save the output of the backtrace command and post it to http://www.neostats.net/boards/ 5. Be sure to save the ircd binary, the modules, and the core file in a safe place in case the developers need to look deeper than a backtrace provides. ---------------------------------------------------------------------- OPENSSL NOTES Older FreeBSD machines sometimes have the obsolete ports version of OpenSSL libcrypto in /usr/local/lib. When configure is used with --enable-openssl, and libintl is detected in /usr/local/lib, the /usr/local/lib directory will be searched BEFORE the system /usr/lib for libraries by the linker. The linker may try to link to the old /usr/local/lib libcrypto instead of the system /usr/lib libcrypto. Some older versions may cause error messages similar to the following: gcc -g -O2 -DIRCD_PREFIX=\"/home/wcampbel/ircd\" -Wl,-export-dynamic -L/usr/local/lib -o ircd blalloc.o channel.o vchannel.o class.o client.o dline_conf.o event.o fdlist.o fileio.o hash.o irc_string.o ircd.o ircdauth.o ircd_signal.o linebuf.o list.o listener.o m_error.o match.o memdebug.o modules.o motd.o mtrie_conf.o oldparse.o numeric.o packet.o parse.o res.o rsa.o restart.o s_auth.o s_bsd.o s_bsd_kqueue.o s_conf.o s_debug.o s_gline.o s_log.o s_misc.o s_serv.o s_stats.o s_user.o scache.o send.o sprintf_irc.o tools.o whowas.o lex.yy.o y.tab.o version.o -lintl -ldescrypt -lcrypto -lfl rsa.o: In function `get_randomness': /home/wcampbel/dev/ircd-hybrid-7/src/rsa.c(.text+0x60): undefined reference to `RAND_pseudo_bytes' /usr/local/lib/libcrypto.so: undefined reference to `ERR_load_RSAREF_strings' /usr/local/lib/libcrypto.so: undefined reference to `RSA_PKCS1_RSAref' *** Error code 1 If this is the case, you may need to rerun configure without the --enable-openssl option, manually edit src/Makefile and modules/Makefile to put -L/usr/lib before the -L/usr/local/lib in LDFLAGS, or remove the old OpenSSL from /usr/local, and recompile all applications that use libcrypto to use the system one.
