Hey all! Trying to learn how to set up dnsmasq, since it will effectively do everything I know about isc-dhcp, bind9 and tftp-hpa in one program, but I can't seem to get it to hand out a simple dhcp address even to a computer directly connected to it! Mind helping a fella out and looking over my configs?

/etc/hosts

please run dnsmasq in debug mode (-d) and see what it says. I'd wonder why you're binding to br0 and eth0 though, maybe that could be causing some conflict? I think you should probably just use "bind-interfaces" and let it listen everywhere possible.

Thanks for the great idea! The reason I'm using bridging is because I have set up virtual machines on KVM and bridge-utils for the interface. I would run the debug, but I got frustrated with the configuration and removed dnsmasq... I've got experience with bind, isc-dhcp & tftp so I installed them instead. Any ideas on how I could sort out using bridging? I'm new to KVM and so I'm going on howtos to get it up and running. Oh, and thanks for the response, much appreciated buddy!

what about using bridging? a simple bridge to the outside world to hook the VM's on to is usually my preferred layout, so so simple... but oddly not something libvirt (used to?) do. I just hacked it in myself in Linux land, and it works fine I find.

Thanks for the info, Chris(?)... and it's nice to see I'm not the only person up late with the Linux bug! Yes, using KVM with bridge-utils is how most howtos I have found say to do it, though I'm having trouble understanding how to use it with other things outside of VMs. Mind elaborating on how you would implement you simple bridging? I'd love to be in the know!
