The "rline" Module


This module adds the /RLINE command which allows server operators to prevent users matching a nickname!username@hostname+realname regular expression from connecting to the server.


To load this module use the following <module> tag:

<module name="rline">


The <rline> tag defines settings about how the rline module should behave. This tag can only be defined once.

Name Type Default Value Description
engine Text None The regular expression engine to use for checking matches.
matchonnickchange Boolean No Whether to attempt to match users when they change their nickname.
zlineonmatch Boolean No Whether to add a Z-line on the IP address of users that match a R-line.

The engine field should be set to the name of a regular expression engine.

The following regular expression engines are included with InspIRCd:

Special Notes

R-lines are expired lazily when a lookup happens for performance reasons. This means that expiry messages may display later than expected.
