Public bug reported: ARGH!!!!! Every release causes new problems >:(
If you have: linux DHCP server on the network with options: option domain-name "xyz.com"; option domain-name-servers 4.2.2.2, 4.2.2.3; In Ubuntu 10.x it works fine and pulls the DHCP client pulls the DNS servers from the DHCP fine. Ubuntu 12.x - It's broken. Trying to fix with: adding to /etc/network/interfaces dns-nameservers 4.2.2.2 4.2.2.3 dns-search xyz.com FAIL. Because you have iface eth0 inet dhcp that option isn't read Try and configure with Network Manager from commandline because your running a server. NOPE, network manager doesn't run from CLI commandline only GUI Can't manually specify the DNS server in /etc/resolv.conf because it's always getting overwritten. What's the best option here? I think this might be a bug. Only option I haven't tried is using the head file from this description: Resolvconf has a /etc/resolvconf/resolv.conf.d/ directory that can contain “base”, “head”, “original” and “tail” files. All in resolv.conf format. base: Used when no other data can be found head: Used for the header of resolv.conf, can be used to ensure a DNS server is always the first one in the list original: Just a backup of your resolv.conf at the time of resolvconf installation tail: Any entry in tail is appended at the end of the resulting resolv.conf. In some cases, upgrading from a previous Ubuntu release, will make tail a symlink to original (when we think you manually modified resolv.conf in the past) ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1045616 Title: DHCP server handing out DNS server but DHCP client not loading DNS settings to client To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1045616/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
