DNSMASQ has problems with 'resolv.conf'

Ashrack · 07-01-2006, 03:54 PM

I've set up internet thru 'pppoeconf'
But whenever I establish a connection
'pon adsl'
the '/etc/resolv.conf' gets overwritten with this:

Code:

nameserver 193.189.160.23
nameserver 193.189.160.13

and then DNSMASQ no longer resolves DNS on LAN. So I must manually add this line to '/etc/resolv.conf' in order for DNSMASQ to start resolving DNS on the LAN again.

Code:

nameserver 127.0.0.1

what does the output of dnsmasq say when you run it in a verbose foreground mode> if it doesn't like resolv.conf it'll be sure enough to just tell you straight away. also what did the resolv.conf file say before it was overwritten. i'm fairly sure that if it sees a 127.0.0.1 entry in the file, it'll dismiss it outright for fairly obvious reasons, so you're left with an identical file basically. also my favourite is to use ethereal or tcpdump to see exactly what it does attempt to do to perform a resolution.

how do I run it like that?

when I disconnect my internet the 'resolv.conf' gets changed to this:

Code:

nameserver 192.168.1.1

which is the ip address of my PPPOE ruter!!!

what are those obvious reasons??

how do I use them, never heard of those 2 tools

verbose output... not sure, look at the manpage, maybe -V, maybe -d can't say.

obvious reasons... well you ARE 127.0.0.1 what use is it to dnsmasq being told to use itself?? just get stuck in a stupid loop.

tcpdump has a great manpage, as does ethereal. you'll probably prefer ethereal if you want a nice gui and all that. so just check the docs, learn a little and you'll be fine i'm sure.
