is there any way to ban the name and the ip ingame? because i allways have to copy the ip and paste it in the banned-ips.txt
If you type "/ban-ip <IP>" then yeah, so long as you're an OP. Alternately, you can type "help" into the server dialogue and it'll show you a list of commands. So long as you're an OP, then you can use most/all of these commands from in the game by putting a slash in front of them. That said, Bukkit is still a little funny in this area, and those commands don't work every time. If it doesn't do anything, just try again.
