I am seeing a bunch of these when running netstat:

tcp 0 384 servername.domain.com:sonar adsl-69-107-115-60.ds:59612 ESTABLISHED

So what is "sonar"?

It looks like so sort of persistant connection? And how would I break this?

Thanks for any advice!!!

From /etc/services:

sonar 572/tcp # sonar
sonar 572/udp # sonar

Find out what process is using the connection like this:

Code:
netstat -anltp|grep -i sonar
Once you obtain the process id, you can terminate it with

Code:
kill -9 <PID>
Be sure to investigate the process.
