Abstract
This is a system which allows users to login in to a UNIX machine via a web browser or WAP phone. This system is more about providing mobility to the users. Via a Client Browser, the user enters the URL of the HTTP Server Host providing access to the desired Login Host. The user is presented with a login page, into which they enter their username and password and then submit this information to the HTTP Server. Then the user is logged into the Unix machine and is allowed to execute the commands using the browser. P ....etc
