Re: [Dnsmasq-discuss] is there anybody who can tell me how to read the source code?
Of course, tools like doxygen can help by automatically graphing the function call tree.

Somebody already ask something like that a few weeks (months?) ago. The best suggestion one can made is probably to start reading and trying to understand it on your own and then ask specific questions when something is not clear to you. ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss

[Dnsmasq-discuss] multi-homed server with same hostname on 2 subnets
Hi, I have a server using two interfaces for different subnets, with the same hostname on both. The subnets are: 192.168.0.0/24 192.168.1.0/24 I've gotten each interface to get the correct IP from dnsmasq using: dhcp-host=eth0,myserver,192.168.0.10 dhcp-host=eth0,myserver,192.168.1.10 but when dnsmasq is asked to resolve the address of myserver it always answers with 192.168.1.10 regardless of what subnet the request came from. What's the proper way to setup this up? Thanks, -Craig ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss

Re: [Dnsmasq-discuss] multi-homed server with same hostname on 2 subnets
Awesome. I love dnsmasq. BTW, re: the subnets, why would that be a problem? I have complete control over the router, I can change it, set up static routing, etc. if I ever need to connect the two subnets.
