A socket is fundamentally nothing but an end point of communication. It can be of two types: Physical socket and Logical socket. In Logical socket operating system has its system calls, which creates them. Now for client-server access the socket needs three things to provide service or ask for service.
1) Service name (example: telnet)
2) Protocol (TCP-stream)
3) Port no (23)
The service uses protocol and protocol uses port number to provide service at server end and to get service at client end. Ultimately we find that the port number is mainly responsible for a client server communication. The protocols supported by Linux is shown by /etc/protocols and the services can be seen in /etc/services

Setup:
The Web server is meant for keeping Websites. There are three ways a Website can be stored. They are:
1) default directory hosting
2) virtual directory hosting
3) virtual domain hosting
We have to first configure the DNS. Then configure the following file (redhat 6.2) /etc/httpd/conf/httpd.conf If we use Apache as a Web server whether on Windows platform or Linux, the main file which is used is called /etc/httpd/conf/httpd.conf

TkApache is a full GUI front-end to configuring and monitoring an Apache web server. Full access to the configuration files is provided and includes management functionality (start, restart and kill), process(es) overview and much, much more. Future functionality will include on-screen graphing and log-file reporting

Imagine you live in a medieval kingdom, and you're the poor sap the king just named to design his new castle.

"A nice one," he says, "and make sure it's impenetrable!"

(Stick with us here, this'll get relevant soon.)

You might build walls so tall and thick that no machine can penetrate them, stock the mote with alligators, and keep the oil boiling for any barbarian hordes passing by. Keeping people out of the castle isn't hard ... until the king mentions he's after a drawbridge, too.

Are you disgusted or disappointed with your current web host? Have you switched web hosting companies too many times? Have you thought of hosting your own website(s)? Do you have the ambition to control and manage your own web server?
