Recently I have added a new machine to my network. This machine is running Debian 7.7.0 and has the following installed screen, jdk and mysql. If the machine is offline all other devices on the network get about a 20ms ping. If the machine is online all other devices get around 1000-2000ms ping. I have no idea how to diagnose the problem and fix it. I suspect the problem is within mysql. Any help is appreciated.

Why do you suspect the problem is within MySQL? Do you have any devices connecting to MySQL that could be generating network traffic ?

On the machine its self is a minecraft server which has multiple plugins that connect to it. However the lag still occurs when the server is not running so I am not sure.

You need to better understand the traffic thats flowing over your LAN so that you can understand where/why delays are occurring. Fortunately there are plenty of tools that will let you monitor this.

Upon further inspection the machine is opening thousands of connections to OVH Hosting. When I attempted to block the IP it reconnected to a different one. Is my machine being used by a botnet? How could I stop this? The machine is on my home network so it should not have any association with OVH.
