  • Haven't seen those before. I'll have to add a message telling us which command is actually failing.

  • I've just seen a case where these messages will appear as a consequence of the Beagle's DNS file getting truncated (hence no outside web sites can be contacted by name). The file /etc/resolv.conf on the Beagle normally has the ip address of a DNS. If you're using DHCP (the default) to set the Kiwi's ip address then an entry win this file s made automatically. But if the file becomes truncated (zero length) then sites like sdr.hu can't be reached and this error will result.

    So the underlying question is why does that happen and should there be a "watchdog" function to restore the DNS to a known server (e.g. Google DNS at 8.8.8.8) if the file becomes truncated.
