Unknown connections from ACC

m.fischer
Hello,

every hour at the same time I see the following connections from ACC:

11:00:07.405570 IP 10.23.160.171.62180 > 216.167.31.83.33436: UDP, length 12
11:00:07.405821 IP 10.23.160.171.62180 > 216.167.31.83.33436: UDP, length 12
11:00:10.211172 IP 10.23.160.171.62180 > 216.167.31.83.33439: UDP, length 12
11:00:10.211415 IP 10.23.160.171.62180 > 216.167.31.83.33439: UDP, length 12
11:00:13.106732 IP 10.23.160.171.62180 > 216.167.31.83.33442: UDP, length 12
11:00:13.107028 IP 10.23.160.171.62180 > 216.167.31.83.33442: UDP, length 12
11:00:16.167258 IP 10.23.160.171.62180 > 216.167.31.83.33445: UDP, length 12
11:00:16.167498 IP 10.23.160.171.62180 > 216.167.31.83.33445: UDP, length 12
11:00:19.133306 IP 10.23.160.171.62180 > 216.167.31.83.33448: UDP, length 12
11:00:19.133492 IP 10.23.160.171.62180 > 216.167.31.83.33448: UDP, length 12
...and so on.

These connections goes every hour to three servers, every hour at the same time to the same servers:

ds80-237-192-98.dedicated.hosteurope.de: 80.237.192.98
15.telemaxx.net: 213.144.15.25
216.167.31.83 (no dns-entry found)

The source port varies between  45118-62180, the destination port varies between 33435-33449.

The ACC is behind an Upstream proxy and has no direct internet-connection. The upstream-proxy is not used for the above connections and I have no idea, what this is for.

Has anyone an explanation?

The ACC is the VMware-version, unmodified from Astaro.

Regards,
Manuel

    Hi Manuel,

    the ACC is trying to find the nearest and fastest Up2Date server via netselect (using a mechanism similar to traceroute). If you need to pass the requests through another ASG, you can enable traceroute forwarding.

    Cheers,
    Henning

    Hi Henning,

    Thanks for your clarification! But, does this makes sense, when an upstream-proxy is configured? The ACC has absolutely no direct internet connection. The only way to go to the internet is via the configured upstream-proxy...

    Regards,
    Manuel
