tcpdump, resolv.conf and leases output
I have the router on my lan configured to provide "Domain-Name-Server Option 6" with a list of dns servers to every client requesting a dhcp lease.
The dns servers are listed in order of preference. I am trying to achieve that local dns server is the primary resolver for clients.
In the attached txt file you can see some output of tcpdump, /etc/resolv.conf and /run/systemd/netif/leases/*.
In my example 192.168.178.70 is my local dns server and 188.8.131.52 is my upstream dns server.
No matter in what order my dhcp server serves the name server list in dhcp option 6 (see tcpdump output), systemd-networkd always puts the 184.108.40.206 on top in /etc/resolv.conf.
I could not find any documentation describing this as expected behaviour.
It helps to always specify exact version of the software being used.
This should be fixed in git: http://cgit.freedesktop.org/systemd/systemd/commit/?id=822db23cfa.
How silly of me, I am using:
$ cat /etc/os-release
$ pacman -Q systemd
and not sure if it is relevant but I use wpa_supplicant to manage my wireless:
$ % pacman -Q wpa_supplicant
Is that enough information?
I'm don't use arch, but judging by https://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/systemd, that patch is not in 219-6. I think we can assume that it is indeed fixed in git. Please reopen if this is still an issue with systemd-220.
Hi Zbigniew Jedrzejewski-Szmek,
Thanks for assistance. Appreciated.
If v220 still does not 'solve' this I will reopen other wise we will consider it as fixed.
