someone is hacking my server by access my cmd

Just for some days ago until today, a hacker destroyed my stuff and got into my cmd! The hacker din't stopped to hack my server so i need help. My server got hacked in 3 days now and i can't find a way to stopp it. Please i need help I would never complete the CTF map if i don't get any help!

 

In your server.properties what is online-mode set to?

 

Can you clarify what you mean by "got into my cmd"?

 

Well it's online-mode. While me and my friend were working on CTF bridge, then i notice the hacker did something to my cmd (run.bat). I notice he did "Can't keep the server up" (actully it said more than that, so it came alot of those.

run.bat

That's not a hacker. Please post the content of your run.bat.

 

Do you mean can't keep up with the server? It's only there for delays and stuff. But if you don't want your console to be flooded, set the warn-on-overload on bukkit.yml to false. As for the hacker, I think it's just your friend playing tricks on you

Code:

settings:
  allow-end: false
  warn-on-overload: false <------- THISSSSS!!!!
  kick-on-speedhack: true
  spawn-radius: 0
  permissions-file: permissions.yml
  update-folder: update
  ping-packet-limit: 100
  use-exact-login-location: false
  plugin-profiling: false
  connection-throttle: 4000
  query-plugins: true

 

Can you provide a screenshot please?
