    I have been following the instructions in http://www.howtoforge.com/set-up-a-loadbalanced-ha-apache-cluster-ubuntu8.04 to set up a loadbalanced cluster. All the instructions in the article seem to work correctly up until the last step where you hit the virtual IP address in a browser. That returns an "Unable to connect" error. I am able to ping the virtual IP address from the computer I am trying to connect from, but I am unable to see any web pages.

    This is the first time I have attempted to set up a cluster, so this is something of a learning experience for me. Any help would be greatly appreciated. Thanks.

    Can you post the outputs of

    ip addr sh eth0 
    ldirectord ldirectord.cf status
    ipvsadm -L -n
    /etc/ha.d/resource.d/LVSSyncDaemonSwap master status
    from both load balancers? Any errors in your logs?

    I did not see any errors in the /var/logs/messages file. There was a bit of logging where on load balancer went down and the standby took over properly.

    Looks ok (is the virtual IP)?

    Do you use a firewall that maybe blocks

    I turned the firewall off completely. The cluster is a set of VirtualMachines that reside on my computer. Turing the firewall completely off solves a number of other problems and I can control access to the virtual machines. The virtual IP address is I can get the load balancer working with the index.html page that is stored in the /var/www/index.html file, just not any other web service.
