dnsmasq doesn't work with pppoe

[Ingmar]

Binary package hint: dnsmasq

Hello,

I'm trying to configure dnsmasq as a dns-server for the internal network and as a forwarder for my internet connection I use with PPPoE.

After starting the machine without a cable to my dsl-modem I have a working dnsmasq for the local hostnames. But if I open the PPPoE-Session I don't get my hostnames resolved. It also doesn't work after restarting dnsmasq. But if I start dnsmasq manually witch the following command: "/usr/sbin/dnsmasq -d -u dnsmasq" it works again. Maybe there's a bug somewhere in the dnsmasq-package.

My System runs Ubuntu 8.04.1, dnsmasq is 2.41-2ubuntu2.1.

Is dnsmasq actually running? If not, you should read the is a question about ppp in the dnsmasq FAQ (http://www.thekelleys.org.uk/dnsmasq/docs/FAQ):

Q: Dnsmasq fails to start with an error like this: "dnsmasq: bind
   failed: Cannot assign requested address". What's the problem?

A: This has been seen when a system is bringing up a PPP interface at
   boot time: by the time dnsmasq start the interface has been
   created, but not brought up and assigned an address. The easiest
   solution is to use --interface flags to specify which interfaces
   dnsmasq should listen on. Since you are unlikely to want dnsmasq to
   listen on a PPP interface and offer DNS service to the world, the
   problem is solved.

dnsmasq is running but only when I start it manual as described above. ("/usr/sbin/dnsmasq -d -u dnsmasq")

I configured dnsmasq to only listen on lo and eth0:
interface=lo
interface=eth0

So it don't seem to be the problem which is described in the dnsmasq-FAQ.

Could you provide the corresponding /var/log/syslog outputs for:
- when you run "sudo /etc/init.d/dnsmasq restart"
- when you run "sudo /usr/sbin/dnsmasq -d -u dnsmasq"
Thanks !
