Re: ISO or virtual appliance

That appears to be a strange desire.  If you need such high levels of "never allow a normal retry" you might look at using either Prolexic or Akami services to create a geographically-diverse network topology.  Or even a simple 3DNS or router package at your borders with a few inner-DMZ systems

Strange problem with a query deleting a record...

Greetings All, First of all, I apologize if this is out of place - I'm having a very strange issue that is either a problem with bind itself, or at least, affecting it. Summary: For only ONE address, whenever I attempt to access it through my squid proxy, the record disappears from DNS, and t

RE: ISO or virtual appliance

lbnamed is a DNS server written in Perl. You delegate a zone to it, and let it dynamically figure out the best IP address to return. See http://www.stanford.edu/~riepel/lbnamed/ There are 3rd-party appliances that do similar functions, such as F5's GTM or Cisco's GSS. Mike Mitchell __

Several years ago I used a Perl script called "lbnamed" that monitored status and returned the host IP address that was least loaded. Mike Mitchell Original message From: Steven Carr Date: 08/21/2013 10:25 PM (GMT-08:00) To: bind-users Subject: Re: ISO or virtual appliance
