** Description changed: - [rational] + [rationale] When using ppp from Network Manager (VPN or modem), the hook script from resolvconf will be triggered and adds the DNS directly to /etc/resolv.conf. That's wrong as Network Manager already handle these and can lead to broken DNS resolution. [test case] 1) Setup a connection in Network Manager using a ppp backend 2) Connect 3) Check that only 127.0.0.1 is present in /etc/resolv.conf 4) Check that /run/resolvconf/interface/ppp0 doesn't exist [regression potential] The change in the check only applies to the case where the script is called with "nm-pptp-service-", so only potential regression I can see is a case where someone manually runs ppp with the exact same parameter as Network Manager, but that'd be wrong... - - - I have a VPN set up in Network Manager, which worked well when my system was running 11.10. + I have a VPN set up in Network Manager, which worked well when my system + was running 11.10. After upgrading to 12.04, I've noticed that DNS changes needed by the VPN aren't happening. Hosts that only resolve within the VPN won't resolve, and hosts that are supposed to resolve with different IP addresses inside the VPN don't. I can see the new, proper nameserver configuration in /var/run/nm-dns- dnsmasq.conf. I can resolve properly if I query the name server directly, i.e. "host <name-to-resolve> <vpn-dns-server-ip>". And, if I use that IP address instead of the name, I can successfully do things like ssh. But simple resolution appears to still be using the old name server. At one point, I killed off dnsmasq and wrote a new /etc/resolv.conf with the VPN name servers. That worked, but caused all manner of problems later.
