Installation works fine, but virtual servers will not start. Why?

On starting a virtual server for the first time, users areoccasionally confronted with the following warning:

   WARN:Could not run virtual server on [host_ip:port] : Bind failed\\     : Cannot assign requested address

First check that the IP-address is valid for your machine. Type:

   /sbin/ifconfig -a

and check [host_ip] shows up as a valid running IP address onyour machine.

Next, ensure you don't already have a web server that is running onport 80, e.g. a copy of Apache that might have been automaticallyinstalled on startup. To check this, type:

   netstat -ant | grep LISTEN  | egrep ':(80|www)'

If any output is displayed, this shows you already have a web serveron that address. Run a 'ps -aux' to find the process id, andkill off this web server (and also update your startup rc.dscripts to prevent starting this server automatically, check your OSmanual for details).
