Ed, Many thanks for the suggestion. You're quite right - my server-side idea was effectively re-inventing the wheel. I've ended up going with rbldnsd, which has been a breeze to setup for this task (even with millions of records) and no code changes were required. The next step is to focus on the

[Dnsmasq-discuss] Using a secondary set of nameservers for dynamic blocking

2011-08-07 Thread Sam Crawford
Afternoon, I'm looking to selectively block certain domains using dnsmasq by rewriting responses. I realise this can already be done statically through config files, but I want this to be more dynamic and intend to operate a set of DNS servers that maintains a list of blocked domains (as this will
