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.
Roll your own monitoring system and have it modify the DNS RRset via
Dynamic Update (if you prefer) to reflect which server(s) are up/down at
any particular time.
That's essentially what all these fancy, expensive GSLB boxes do anyway.
