I need help to this... I use ubuntu. My server is dossed? Can someone help me

 

Try contacting your host or administrator for your router. To find out if you are being DDoSed you have to check your incoming pings.

Please post a www.pastebin.com
of your start up log.
it can be beause of a command block with a redstone repeater also. has your server ever been up?
BTW, you can type in /stoplag in your console so if it is a command block, you can stop the repeated command
