Hi Serdar, Instead of "rndc reload" can you try "rndc reconfig"? This may work in this environment and should be faster. Hope this helps.

We have an amazing censorship in here, youtube, dailymotion and dozens of websites are blocked on DNS level, some of them have been blocked by their IPs. So, we would like to build couple of DNS servers, which will redirect those websites to their non-blocked IPs. We won't have additional configuration for websites which have been blocked on DNS level, as you guess. However, we also want to provide content filtering, like phishing, badware, adult filtering. We expect around 10.000 queries per second in the mid-term. We want to setup this system with minimal patching. So, Bind is good solution at this moment as it's authoritative and caching servers work together. We are still doing R&D by the way. We will setup around 200-300 domains with their zones. They will be for blocked domains. We will also setup around 200.000-250.000 domains, with Bind's "views" feature. All the domains will point to one zone file, which will redirect requests to our web server. So, if someone want to have badware filtering, we will put his/her IP to the ACL. We did some experimental testing, and it worked perfectly, but when we add 200.000 domains to the config file, reload takes more than 20 minutes. We have used Core2Duo, 2 gb ram computer in this test. We need to reload the config once an hour, so with this result, it will make it impossible. Since we have only 300 zones, reloading zones is not a solution. We need to reload ACLs, and 200.000 domains. Is there any different solution for this? For example we can separate the config files, and reload only some files, is it possible? Bind DLZ isn't a good solution because as I said we expect 10.000 queries per second in mid-term and don't know what it will be in the long term. Performance is important. We can also buy some mid-ranged servers, but I don't know whether it will make big difference (20 min to under 30 sec - 1 min) If I missed something obvious, sorry from now on. Thanks, Serdar Sahin
