Module: ngircd.git Branch: master Commit: 6e8cf51bb216f956e7a6fdb5c61b0f2799bf8d2d URL: http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=6e8cf51b… Author: Alexander Barton <alex(a)barton.de> Date: Thu Feb 11 00:01:53 2010 +0100 Implement WEBIRC command The WEBIRC command is used by some Web-to-IRC gateways to set the correct user name and host name of users instead of their own. Syntax: WEBIRC <password> <username> <hostname> <ip-address> The <password> must be set using the new configuration variable "WebircPassword" in the [Global] section of ngircd.conf. Please note that the <ip-address> is currently not used by ngIRCd (we don't store it in the CLIENT structure, only the resolved hostname). --- doc/sample-ngircd.conf | 8 +++++++- man/ngircd.conf.5.tmpl | 5 +++++ src/ngircd/conf.c | 30 +++++++++++++++++++----------- src/ngircd/conf.h | 5 ++++- src/ngircd/conn.c | 12 ++++++++---- src/ngircd/irc-login.c | 27 ++++++++++++++++++++++++++- src/ngircd/irc-login.h | 3 ++- src/ngircd/parse.c | 3 ++- 8 files changed, 73 insertions(+), 20 deletions(-) diff --git a/doc/sample-ngircd.conf b/doc/sample-ngircd.conf index b945224..db326c9 100644 --- a/doc/sample-ngircd.conf +++ b/doc/sample-ngircd.conf @@ -28,9 +28,15 @@ # LINKS requests for example.
