+Description: A lightweight daemon for the Internet Relay Chat (IRC)
+ ngIRCd is a free open source daemon for the Internet Relay Chat (IRC)
+ network. It is written from scratch and is not based upon the original
+ IRCd like many others.
+ .
+ In addition to the features of the "standard package", this package
+ includes support for TCP wrappers, IDENT requests, the IPv6 protocol and
+ SSL encrypted client and server links.
+ .
+ And in addition to the "full" variant, the binaries contained in this
+ package are build with debug code and contain debug symbols.
+ .
+ Advantages of ngIRCd:
+  - no problems with servers using changing/non-static IP addresses.
+  - small and lean configuration file.
+  - free, modern and open source C code.
+  - still under active development.
+ .
+ ngIRCd is compatible to the "original" ircd 2.10.3p3, so you can run
+ mixed networks.

Alexander Barton	b1852f3029	Updated Debian "changelog" file for ngIRCd 14.1	2009-05-05 13:14:23 +02:00
Alexander Barton	822c1e9265	ngIRCd release 14.1	2009-05-05 12:58:51 +02:00
Alexander Barton	5b4a3eda08	Added start/stop script for Red Hat based distributions Script contributed by Naoya Nakazawa <naoya@sanow.net>.	2009-05-05 12:50:55 +02:00
Alexander Barton	a83554b572	Renamed contrib/ngircd.sh to contrib/ngircd-bsd.sh	2009-05-05 11:41:26 +02:00
Florian Westphal	627b0b713c	security: fix remotely triggerable crash in SSL/TLS code When a server is running with SSL/TLS support compiled in, it is trivial to crash the server by sending an MOTD request via another server in the network. - ONLY servers without ssl/tls support compiled in are not affected. Disabling SSL in the configuration (no ssl listening ports, etc) does NOT help. - servers that are running standalone (i.e., not connected to any other servers) are not affected, either. This affects all ngircd releases since ngircd 13 (earlier versions have no SSL/TLS support).	2009-05-05 10:21:20 +02:00
Alexander Barton	95428a72ff	Fixed "Conflicts:" line in debian/control: missing comma	2009-05-04 11:23:19 +02:00
Alexander Barton	6b83d1740e	Debian: build ngircd-full-dbg package In addition to the "ngircd" and "ngircd-full" packages a new package named "ngircd-full-dbg" is build: this package contains all the features of the "full" package but includes debug code and both the --debug and --sniffer options and the resulting binaries are _not_ stripped.	2009-04-29 02:14:17 +02:00
Alexander Barton	c8bba8e5c3	debian/rules: whitespace fixes	2009-04-29 02:12:56 +02:00
Tassilo Schweyer	37359799eb	Fix server list announcement When ngircd announces the list of currently known servers to a new (connecting) server, it sent the introducer of the servers instead of the top server. Assuming this network: irc1.example.com \|--irc2.example.com \| `--irc3.example.com \| `--irc4.example.com `--irc5.example.com When irc4 connects to irc3, irc3 tells irc4 that irc5 was connected to irc2. (irc2 had introduced irc5 to irc3; but thats not what ngircd should have sent to the new server). This also placed users on the wrong servers.	2009-04-26 00:30:49 +02:00
Alexander Barton	4a14fb252d	Doxygen: update source code repository link to GIT	2009-04-25 00:53:47 +02:00
David Kingston	9b59f043c8	allow ping timeout quit messages to show the timeout value	2009-04-23 21:39:45 +02:00
Florian Westphal	b545d38ae4	irc-server: do not remove hostnames from info text that code does not really make sense -- the info text is freely cofngiureable and des not follow a specific format. Also, that "+2" might have caused invalid memory accesses.	2009-04-22 23:15:17 +02:00
Florian Westphal	84eaed6c9a	conn-zip: fix error handling callers of (Un)Zip_Buffer() assume that the function closes the connection on error. However, this was not always the case.	2009-04-21 21:00:43 +02:00

With this patch ngIRCd displays IPv6 addresses as "[<addr>]:<port>" when accepting new connections and later, if no successful DNS lookup could be made (or DNS is disabled altogether).	2009-04-10 13:22:03 +02:00
Alexander Barton	d9355d53f8	Xcode: #define include __DATE__ in VERSION Change VERSION to include the __DATE__ when compiling from within Xcode. When building using "make xcode" or "make osxpkg" VERSION already is defined to the "real" version number set in configure.in.	2009-04-10 13:08:04 +02:00
