http://www.linuxvirtualserver.org that may be worth looking into. From a quick browse of the docs it looks like it has heartbeat functions and will offer scalability for the future.

There are some alternatives to buying hardware (I use an F5 product), heartbeat moinitoring is goodway to do it, but can take some setup, but there are probably scripts somewhere to make it easier. ServerA should have IP 2.2.3.4, ServerB 2.2.3.5. You also add to server a 1.2.3.4 and serverb 1.2.3.5. Using scripts you monitor if squid is up on 1.2.3.4 and 1.2.3.5. If squid fails on one, you have the scripts remove the IP from th failing host and place it on the host that is working. (hint: on my network I have to ensure I do a ping from the IP so the network knows where the IP went to.) Thats not a complete description, but you get the idea, also you have to monitor the 2.2.3.* address so that when squid on the box that fails starts again the scripts will undo the changes it made to deal with the fail. I hope this gives you a few ideas, Stewart On Thu, 21 Nov 2002, Mark Lewis wrote: > Date: Thu, 21 Nov 2002 11:54:22 -0600 > From: Mark Lewis <[EMAIL PROTECTED]> > To: [EMAIL PROTECTED], Chris <[EMAIL PROTECTED]> > Subject: Re: Load Balancing SquidGurad Servers > > You could do this a couple ways, round robin DNS would half do it, but would > not take one out of rotation if it failed. > We have 8 proxies and use a Cisco Local Director to do this.
