    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.

    Regards
