how to archieve this?
Hello, We are running a commercial site. We want bind to execute some additional actions before the response, listed as below: 1) Client querys for www.site.com's ARR. 2) Bind gets client's IP, and calculate something based on this IP. 3) If IP matchs condition A, return the ARR of www.site.com - 1.1.1.1. If IP matchs condition B, return the ARR of www.site.com - 2.2.2.2. If IP matchs condition C, return Refused. How to implement this architecture on Bind? Does Bind provide some programming API like Apache's APR? Thanks in advance. Ken. ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

It's old and probably has some bugs in its protocol handling, but it does something along the lines that you're looking for. Thanks for the info. I have checked the lbnamed. All my feel unsure is, how about its performance? Since it's written by Perl, not a compiled program.Has anyone used it in production environment? Thanks.

But views is not suitable to our application. Because views is working based on the different IP datas. We don't want the response is based on geography locations, but based on others, ie, which realserver has the best network connectivity. Thanks.

Or, does Bind developer group provide commercial development for this purpose? We can pay for it. --- On Fri, 12/5/08, Chris Buxton [EMAIL PROTECTED] wrote: From: Chris Buxton [EMAIL PROTECTED] Subject: Re: how to archieve this?

You may need to write your own name server implementation, using a set of F5 appliances, or something else. ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
check Availability before sending response
Hello, Is there any way to make Bind check the server's availability before send back responses to clients? ie, given the domain name www.site.com was pointed to 1.1.1.1 and 2.2.2.2 in Bind. When a client query for www.site.com, Bind will check the health status for these two servers. If one is unavailable,Bind shouldn't direct client's requests to it. I know F5's 3DNS can do it well.But rather than 3DNS, is there any free way for this purpose? Thanks.
