(doing "sudo /usr/bin/ntpd -s" once after the start is ok, though )
I think I got my Problem.
The DNS has to be set at 8.8.8.8, but that doesn't happen with DHCP and I don't have admin access to the Router. I also tried with raspbian this afternoon but I simply can't connect to the Internet. Is there a Chance to set the DNS to 8.8.8.8?
I tried to set
iface eth0 inet static
address 192.168.1.17
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
And had gateway and / or network set to 8.8.8.8 and played around several variations. But it wasn't possible to do any Updates.
Which of these Adresses has to be set at 8.8.8.8? And will it work without any Changes on the Router? The RasPi is connected via cable, not Wireless.
Thanksalot so far for Your Assistance!
