The FLOOD type is activated whenever someone sends a lot of information very rapidly to you, your channel, or the system at large (ie: a wallop). Usually, this is caused when someone dumps a file to your channel or to you. The parameters for this are:
$0 The nick of the flooder
$1 The target of the flooder
$2 The type of flooding being done
$3- The content of the flooding message
General use for ON FLOOD is as follows:
ON ^FLOOD *
This will automatically prevent flooding messages from being
displayed and automatically disable itself when the flooding
has stopped.
If you use services like IRCIIHelp or NickServ, these can appear to IRCII as floods, but if you add the two following ON lines:
ON FLOOD ^IRCIIHelp
ON FLOOD ^NickServ
These will not be treated as floods and will let their messages through.
Warning: There are occasions where on/flood can be inadvertantly activated (such as after a net-burp, or after you have ^Z'd for a while). Therefore, I strongly advise against using KILL or even kick as the action taken by an on/flood.
Note that in ircII 20020902 and earlier, $1 is not the target of the flooder, but the type of flooding being done, and $2- is the content of the message. For example:
IF (V > 20020902) {
ON FLOOD "% % % *" ECHO Flood type $2 from $0 to $1: $3-
} {
ON FLOOD "% % *" ECHO Flood type $1 to $0: $2-
}
