    Yea a player can actually seem to just come in on their own and do this, which is enough to hang and crash the whole server. What is it caused by, and how can I prevent it?
     
  2. You could just kick them from the server after a few violations of that rule. I'm not sure if OFC is a plugin or some in-built functionality but perhaps it has a feature for that. There may be a plugin for it.

  3. We ipbanned them. They just changed IP and returned. And you can't kick them during the dos, because the server is hanging
     
  4. I'm sure the server won't be hanging after the third or forth entry on that list. That's when you kick them. Using a plugin, of course (so they are kicked automatically).
     
  5. rangeip ban their location for a while? Also make sure u have something like VPNGuard installed (Does work)
     
  6. Well the problem is them starting the dos in the first place, not getting rid of it

    Whoever they are, they're using a vpn, so range ban doesn't work either. I could try vpnguard and see soon.
     
  7. Could u rangeip ban ovh (lol)? And any other popular server hosts.

    I'm assuming the server is being run in offline mode?
     
  9. Yea it's a dev server that exists just to promote and test a plugin, so we just allow anybody in to maximise player count

    Unfortunately, it also allows people like that on your server as well.
    Is this a 1.8 server? I recall seeing a patch or plugin not long ago in regards to something like this.

    I can only suggest setting the server to online mode until he goes away. This will prevent anyone from logging in without a mojang account..
