Pawer child killed

Hi Guys and Girls,

I’ve received my USB dongle today, at this time i’m trying to get Piaware running, but it’s giving me a Child Killed message…
Has anyone got a clue what this causes?

Thanks and kind regards,

Is your Pi definitely online and have working DNS?

Well, it’s working now, i’ve set the DNS servers to the DNS Servers of my ISP, but i get the same messages.
Should I be worried…?

Update: I’ve figured out that this messages are caused by the Quagga daemon, which is at the same Pi…
When i disable that daemon temporary the error’s are gone :slight_smile:

Quagga is for dynamic routing, and provides connectivity to my internal network by a OpenVPN Connection
