With this plugin you can ban griefers and other annoying people from your "offline" Server. To combat dynamic IPs EasyBan keeps track of players IP addresses and saves them into a file or database. Additionally you can ban entire subnets and/or countries if necessary. You can also add different DNSBL to block unwanted client hosts(open proxies, tor exit nodes, and much more). The plugin has support for Permissions (via bukkit API). When no Permissions plugin is installed all commands default to OP.
