Before you mark it as a duplicated please listen to the problem. I took a lot of time searching on this issue and found very similar problems but none of them solved it because the suppose solution files simply doesn't exist.
I have two interfaces on my Fedora 22 machine, which one as a different DNS server. At the
/etc/resolv.conf the first nameserver is the nameserver of my school and then comes my nameserver. I want to solve DNS queries of
mydomain.com that my school domain doesn't know. On this scenario the query must be asked to my DNS server. I solved this issue on other machines by updating
prepend but at this machine this file doesn't exist. Any suggestions?
It might be worth to tell that I'm using NetworkManager service to configure those interfaces.
I found that
/etc/dhcp/dhclient-eth0.conf might be what I'm looking for. Does the option
supersede is acceptable here too?!
