NM DSL connection: DNS server addresses not added to resolv.conf

[Uqbar]

How to trigger (I used KDE widget)

1. Select Network Manager Settings
2. Select DSL tab
3. Select "Add ... +" button
4. Select "System connection"
5. Select IPv4 address
6. Select method: Automatic (address only)
7. In DNS servers add your own DNS server (I used 8.8.8.8; 8.8.4.4)
8. Click on OK
9. From a terminal, as root, type: "sudo vi /etc/NetworkManager/system-connections/New\ DSL\ connection \ connection" (or whater is in your language).
10. Check in the IPv4 stanza that the configuration is the same as above
11. Enable the DSL conection from the widget.
12. From a terminal type " cat /etc/resolv.conf" and see that the DNSs are not the ones specified in step #7.

Status changed to 'Confirmed' because the bug affects multiple users.

[Ron (ron-atkins)]

I don't think this is related to DSL. I'm on a LAN and specify a DNS server and search domain, but they are not honored. Disabling dnsmasq resolves the problem.

[Thomas Hood (jdthood)]

What was originally reported is expected behavior. NetworkManager starts a dnsmasq process to forward DNS queries. NM puts (via resolvconf) "nameserver 127.0.0.1" in resolv.conf and sends the upstream nameserver addresses to the dnsmasq process over D-Bus.

On the other hand, if DNS search domain names are not included in resolv.conf (as Ron just reported) then that *is* a bug.

[Thomas Hood (jdthood)]

Ron: You report that manually-added-in-NetworkManager DNS search domain names are not added to resolv.conf. Can you please give step-by-step instructions for reproducing this bug (as Uqbar did)? Also, please post the output of this command:

    ls -l /etc/resolv.conf
