In file "groups" you can list users who have right to force other users out. Format is as follows:
username1=can_kill username2=can_killThese users can send the server fuse-protocol-command "USERKILL username". To other users it does not do anything.
This command disconnects immediately user's connection and assings a variable length ip-banning. Ip-banning means that connections from specified IP-addresses are coldly refused. Ip-bannings are specified in file "bannings".
To understand system better, see class com.fuse.access_control.AccessControl and FUSEClientCommand.handleConnection().
