From: tedd on 28 Aug 2010 15:18 Hi gang: The server global: $_SERVER['SERVER_ADDR'] Provides the IP of the server where the current script is executing. And, the server global: $_SERVER['REMOTE_ADDR'] Provides the IP of the server executing the script. As such, you can enter the IP of either into a browser and see that specific domain. However, that doesn't work when you are dealing with shared hosting. Doing that will show you to the parent domain, but not the child domain (i.e., alias). So, how can I identify the exact location of the 'server_addr' and of the 'remote_addr' on shared hosting? Is that possible? Thanks, Cheers, tedd -- ------- http://sperling.com/

If my server is 192.168.29.104 and my client is 192.168.29.114, I= might get the default website on the server address, and nothing on the= client (assuming it is not running a webserver). > However, that doesn't work when you are dealing with shared hosting. > Doing that will show you to the parent domain, but not the child > domain (i.e., alias). >=20 > So, how can I identify the exact location of the 'server_addr' and of= > the 'remote_addr' on shared hosting? Is that possible? $_SERVER['SERVER_NAME'] will tell you the name of the virtual host - I don't know if that is what you're after. --=20 Per Jessen, Z=C3=BCrich (12.2=C2=B0C)

You see, I can have a script on one server communicate with another script on a another server and the remote addresses reported on either will not translate back to their respective virtual hosts, but instead to their hosts. So, I'm trying to figure out a compliment to $_SERVER['SERVER_NAME'] such as something like $_SERVER['REMOTE_NAME']. Is there such a beast? Cheers, tedd -- ------- http://sperling.com/

For the script on your local host to be able to connect and communicate with the remote host, it would need to know the name of the remote host. Hence, the local host already knows the name and has no reason to ask the remote host for a name by which to contact it. That's what I get from your description of the problem. You probably want to clarify some things.

Try this -- place this script on your site: <?php print_r($_SERVER); ?> You will note that: [SERVER_NAME] => is the domain name of your site. Also: [SERVER_ADDR] => is the IP of your site. If you are on a shared host, then it will still be the IP of the main host. Please note: [REMOTE_ADDR] => is the IP of the remote server. It *will be* the IP of the remote main host regardless of if the requesting script is running on the remote main host OR is running under a remote shared host. Here's an example: My site http://webbytedd.com is running on a shared host. The server address reported for this site is: 74.208.162.186 However, if I enter 74.208.162.186 into a browser, I do not arrive at webbytedd.com, but instead go to securelayer.com who is my host. Now, if webbytedd.com was the requesting script, how could the original script know what domain name the request came from? As it is now, it can only know the main host ID, but not the domain name of the requesting script. Does that make my question any clearer? So my questions basically is -- how can I discover the actual domain name of the remote script when it is running on a shared server? I hope that makes better sense.
