The following commands can be used with the plugin, but if you are not op you will need the permission clientmods.admin to access these commands.
/clientperms query <playername>
Lists a player's supported permissible mods and versions.
/clientperms refresh <playername>
Synchronises a player's permissions with the server, execute this command if you alter player permissions and wish to push the changes to the remote player immediately.
List the mods currently supported by the plugin
/clientperms addmod <modname>
Adds a mod to the supported mods list
/clientperms removemod <modname>
Removes a mod from the supported mods list
/clientperms modversion <modname> <version>
Using this command it is possible to set a minimum supported version for a particular permissible mod. For example if version 1.2 of a mod is found to have an exploit and the author releases an updated version, you can use the command
/clientperms modversion somemod 1.3
to force players to update the mod to version 1.3, players with a version lower than 1.3 will be kicked when joining the server with a message informing them that the mod is outdated.
To clear a mod version requirement, set the required version to zero:
/clientperms modversion somemod 0
To view the current mod version threshold for a mod, do not enter a value for version:
/clientperms modversion somemod
