Hi! If my memory does not let me down, a DNS server makes the translation between IP adresses and hostnames. On any OS, you can specify several DNS servers, so if the first fails down, it tries to reach the second one. But what I have to handle is this: someone on the network requests www.mywebsite.com. The external FW catchs the request, performs a NAT and redirects it to the webserver. But the FW has to know to which web server it has to redirect the request... PS: My web servers are web servers only, not at all DNS servers ... -----Message d'origine----- De : Corey Watts-Jones [mailto:cwattsjones () rogers com] Envoyé : samedi 21 août 2004 06:12 À : Bénoni MARTIN; security-basics () securityfocus com; pen-test () securityfocus com Objet : RE: Securing web site with redundancy ? Hmmm... could you not simply add the second web server to the end of the list for DNS entries? Failing contact with the first listed server it should contact the next entry in line. Correct me if I'm wrong, folks. :) -----Original Message----- From: Bénoni MARTIN [mailto:Benoni.MARTIN () libertis ga] Sent: Friday, August 20, 2004 8:10 AM To: security-basics () securityfocus com; pen-test () securityfocus com Subject: Securing web site with redundancy ? Hi all ! I was wondering if there was a way to set up 2 "redundant" web servers (identical web sites), i.e. when one crashes, the other one takes the connection over. The same thing which is already available for firewalls (high disponibility), but with web servers. We would have 2 Windozes in a DMZ with IIS as the web server, and a pix firewall between the dmz and Internet. Is there any tool allowing this out there ? I tried to google quite a while, but without any chance... Some one has an idea ?
