I own a Kimsufi dedicated server since more than one year, and recently I decided to completely re-install the OS. I installed Debian 8.4 Jessie.
I installed all the updates needed, changed my SSH default port, and disabled root login. For now, I am simply running a MongoDB database on the server (changed the default 27017 mongo port), and a Node.js API, for development. My personal computer should be the only machine knowing my dedicated server existence.
When logging to the administrator console of my server (Kimsufi/OVH), I can see that there is always some traffic, whereas I am not communicating with my server.
When looking at the packets downloaded, it's kind of weird, because every 30 minutes occurs a 4266 pps peak.
I tried to inspect all the data passing through the eth0 interface, using the nload
command, and my server is communicating with some machines.
Is this "normal" ? If not, what can it be ?
Here are some screenshots of my control, panel... See that the traffic is pretty tough
