Module: ngircd.git Branch: master Commit: 5713c49c8480639f08f7fff82fb5a40e8566e1dc URL: http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=5713c49c8... Author: Alexander Barton <alex@barton.de> Date: Tue Mar 18 14:55:38 2014 +0100 Implement user mode "F": "relaxed flood protection" ngIRCd relaxes its flood protection for users having the user mode "F" set and allows them to rapidly send data to the daemon. This mode is only settable by IRC Operators and can cause problems in the network -- so be careful and only set it on "trusted" clients! User mode "F" is used by Bahamut for this purpose, for example, see <http://docs.dal.net/docs/modes.html#4.9>. --- doc/Modes.txt | 3 ++- src/ngircd/conn.c | 11 ++++++++++- src/ngircd/defines.h | 4 ++-- src/ngircd/irc-mode.c | 1 + 4 files changed, 15 insertions(+), 4 deletions(-) diff --git a/doc/Modes.txt b/doc/Modes.txt index aee7491..a931787 100644 --- a/doc/Modes.txt +++ b/doc/Modes.txt @@ -2,7 +2,7 @@ ngIRCd - Next Generation IRC Server http://ngircd.barton.de/ - (c)2001-2012 Alexander Barton and Contributors. + (c)2001-2014 Alexander Barton and Contributors. ngIRCd is free software and published under the terms of the GNU General Public License. @@ -26,6 +26,7 @@ channels he is using at the moment.
