You need to do IP address to hostname resolution. You can accomplish this with DNS, or using "hosts" files. DNS is a beast, so I would recommend starting with the "hosts" method.

Say this is your IP addressing setup:

Linux webserver: 192.168.1.2
Linux client: 192.168.1.3

On the Linux client, you need to modify the file "/etc/hosts". You need to be root to modify it, so su to root first, then open it in an editor, e.g.:

su -
vi /etc/hosts

Then you add an entry for your webserver, on a new line:

192.168.1.2  webserver webserver.localhost www.mywebsite.com

now you can open a browser on the Linux client and put in the address bar any of these:

http://192.168.1.2
http://webserver
http://webserver.localhost
http://www.mywebsite.com

and it will point to your Linux webserver. Technically, to make sure the resolving happens with "hosts" before DNS, you need to check the file "/etc/nsswitch.conf", but by default it is in the proper order, e.g.:

[root@localhost ~]# grep ^hosts /etc/nsswitch.conf
hosts:      files dns

Note that if "www.mywebsite.com" is an actual internet address, your ip address in /etc/hosts will override it (due to the line in nsswitch.conf).

Check out the VirtualHost declarative for Apache, it is what you need.

http://httpd.apache.org/docs/2.0/vhosts/examples.html

Just make sure that on your Linux client PC, you resolve the domain names hosted on the Linux server with the correct IP address. For example, in your Linux client /etc/hosts file, you might have:

192.168.1.2 www.website1.com www.website2.com

It is up to the Apache server to redirect browser requests to the proper virtual host, and it does that by using the domain name used by the client to access the webserver (e.g. "www.website1.com" or "www.website2.com").

Okay, tell us exactly what you did, so that we can better help you.

For instance, did you update the /etc/hosts file on any machines? If so, which machines? What did you enter (show /etc/hosts)? What did you use as the URL in the browser? On what machine did you run the browser?

Also,

A quick test you can do on the client is to try to resolve the hostname of the server to an ip address using ping, e.g.:

ping <WEBSERVER_HOSTNAME>

where WEBSERVER_HOSTNAME is the name of the webserver that you (hopefully) put in the /etc/hosts file on your client PC.

If instead, you are using DNS, you can use the "host" command, e.g.:

host <WEBSERVER_HOSTNAME>

This command should return any ip address records associated with that name on your DNS servers.
