Hi Sanqduen, I think you have a couple of issues here. First, I think the wiki page is wrong in using 127.0.1.1 as the IP address. That is very similar to the common localhost address, 127.0.0.1 . Try changing to that address and restart apache - from the command line enter: "sudo apache2ctl restart". Also, did you do the other steps at the end of the wiki page? You need to change from the example IP address of 123.123.123.123 to a valid address for your network. For servers the address is usually a static address assigned by the network administrator. In some cases it might be automatically assigned and in fact that may be the default behavior. To see what the address is from the command line enter: "sudo ifconfig". That should list the information for the network interface. You are looking for the "inet addr" under "eth0". Hope that helps.
