I got a preconfigured debian image that gets it's network configuration by DHCP, however the DNS server is/was fixed to 8.8.8.8. This was configured using /etc/resolv.conf, so I deleted all the entries there. /etc/dhcpc/resolv.conf contains the DNS server I would like to use, however this DNS server isn't used by the system. How do I activate the usage of the DNS server provided by DHCP? Thanks!
Force usage of DNS server provided by DHCP?
debian;dns;dhcp
I ended up installing isc-dhcp-client, seems to fix the problem. Thanks for all the other hints, though!
