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