Pawer child killed


#1

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?

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
