Welcome to ircu2.10.11, the Undernet IRC daemon Version u2.10.11 of the Undernet ircd incorporates many new features over its predecessor, and we feel that using it will make you very happy indeed. New features include: - A completely rewritten network event engine, which make full use of the asynchronous event engines available in FreeBSD (kqueue) and Solaris (/dev/poll), resulting in dramaticaly improved performance. - New F: (feature) lines in ircd.conf, and the GET/SET commands allow many settings to be changed dynamically, rather than by with compile- time configuration. - The new "account" feature added to the P10 protocol, allows people to remain logged in to service bots (i.e., gnuworld) during a netsplit. This means people will not have to login again once the network rejoins. INSTALLATION Please see the INSTALL file for installation instructions, for hints on how to best configure your OS for running ircu under high load, see the various README. files. COMPATIBILITY This version of ircu will only work with servers that use the P10 protocol, some of the new features will only work between ircu2.10.11 servers. GENERAL PERFORMANCE HINTS For platform-specific notes and hints, see the various README. files included in this distribution. The notes below apply to servers that will serve large numbers (thousands) of clients simultaneously. If your server serves a small amount of users, you will not really have to do much of anything about performance tuning. - Run an OS that supports an asynchronous network event engine; currently these are FreeBSD (kqueue), and Solaris (/dev/poll); possibly other BSDs will also support kqueue. This will have a dramatic effect on performance. - Make things as lean as possible: Make your server dedicated to ircu, disable anything that is not neccesary, and build a custom kernel (where possible). - Tune kernel parameters; see the various README. files as well as your OS documentation for more information. - With many clients connecting each second, ircu will be doing lots of DNS lookups. Make sure that the DNS server(s) in your /etc/resolv.conf are as close as possible, or run a local caching DNS server on your IRC server. TIME SYNCHRONIZATION Many things can and will go horribly wrong when the clocks on the servers on your network become (too far) out of sync. It is therefore highly recommended that all servers run a version of ntpd that will keep their clocks from going astray. INFORMATION HIDING As per undernet-admins CFV-165, this server contains code that will, by default, hide certain information from ordinary users. If you do not want this, please make sure you add -DINCLUDED_ircd_policy_h to CFLAGS prior to running ./configure, like in: > CFLAGS=-DINCLUDED_ircd_policy_h ./configure MORE INFORMATION For more information on this software, see the included documentation in the doc/ directory, as well as http://coder-com.undernet.org.
