Re: Installation and requirement help required on debian sarge

Hi,
 Thanks for your answer.I will explain you my present setup We have two webservers with two different public ipaddresses and some virtual interfaces also in these two servers presently we are giving the same public ipaddress to our dns servers and our users are accessing thier websites in this some are virtual interfaces also.
 
  We are very much interested in ultramonkey software to installe a highavailability and loadbalancing.If we install this we need to change the public ipaddress of websites again.Is there any other solution without changing the ipaddresses using the ultramonkey
 
situation is below
 
1)webserver1
 publicip,virualipaddress
 
2)Webserver2
publicip,virualipaddress
 
if i install ultramonkey one director for each server
 
1)director one
one ip
 
2)director2
 
one ip  pointing to main servers so i need to publish the director ip to my end users.
 
Best Regards

The virtual IP address is that address that end-users will connec to.
This is the address of your cluster. And if you have end-users
connecting from the internet, then it needs to be a publicly routable
address. All other addresses may (or may not) be private RFC1819 addresses.

At least 1, though 3 would be easier.

This does not include the IP address for the router.

You need to install ultramonkey on the linux-directors, this should add
everything you need.

You do not need to install anything on the linux-directors.
Well, except for apache or whatever daemons you want them to run.
