I've set up the default dnsmasq installation and have put the following in /etc/conf.d/dnsmasq:

I think dnsmasq is just not getting the requests. Try running nslookup interactively and select the dnsmasq server by IP (server 192.168.0.20) and then try google.com and see what happens.

Still no luck. Remote machine:

seems to as if you forgot to bind dnsmasq to an interface; insert something like interface=eth0 in its config (asuming eth0 is your internal NIC)

I've done that. Still no luck. Could somebody post a working configuration on this forum? Are there any other files not related to dnsmasq that might be relevant? BTW I don't have a firewall running on my machine. I am somewhat mystified by this.

Can you try to run it interactively to make sure it's not the client as the config etc seems fine.

Type nslookup enter

then server 192.168.0.20 enter

google.com enter

You probably didn't set it up for the box that has dnsmasq installed to do forwarding of packets.

Also you don't need to set up your ISP's DNS servers in dnsmasq. On the box that you've got dnsmasq installed on you just have /etc/resolv.conf have the upstream dns servers.

There's a section for dnsmasq here:

The solution was so simple that its embarrassing to put it here

. Something to do with wrong IP addresses.

As you say - I've just discovered that it works perfectly well straight out of the box with ISP's nameservers in /etc/resolv.conf.

I've trashed djbdns and replaced it with dnsmasq. I'm only using it for a small home network. It doesn't fill my root directory with clutter and is easy for a simple person like me to understand.
