| Hullo I’m trying to build a homenet environment that includes some fedora 25 vms running NetworkManager-1.4.2-1.fc25.x86_64. I’d like these computers to update dns when they get new ipv6 addresses. Working from the discussion on this page: http://bit.ly/2hr2SnC, I was able to construct a suitable dhclient6-eth0.conf to run directly with dhclient by adding a line: send fqdn.fqdn “wibble.example.com” to the file created by NetworkManager in /var/lib/NetworkManager/. With the extra line, the relevant update is forwarded by dhclient. However, I cannot work out where or what to put in NetworkManager’s or the redhat configuration to get NM to create a suitable dhclient6-eth0.conf file. I also noted that the issue noted on the link above about ipv6.dhcp-hostname getting blown away each time the service is reset still holds with the nm version. Am I looking at the right area to get the dns updated? If so, where should I be putting the configuration to get the right autogenerated dhclient file? Thanks in advance TimC |
