I have noticed that there' s always traffic going on on my loopback interface. It's not a lot but I don't know where it's coming from and I'd like to stop it.
There's syn request going from port X to port 9229, then a rst/ack response. Half a second later I get the same from X+4 to 9229, then X+8 and so on?
Is there some service that could be originating it? This is debian testing... and updated a few days ago.
Update 1: I was able to capture this with netstat:
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 1 127.0.0.1:60024 127.0.0.1:9229 SYN_SENT 314481/chromium --s
And this process has:
/usr/lib/chromium/chromium --show-component-extension-options --enable-gpu-rasterization --no-default-browser-check --disable-pings --media-router=0 --enable-remote-extensions --load-extension
What the hell is chromium doing?
Update 2: A HTTP request is sent:
GET /json/version HTTP/1.1 Host: 127.0.0.1:9229
But what is chromium trying to find?
