UNIX for Dummies Questions & Answers

Hello Experts,

Guide me how to add new users (user id , passwd) in unix/Linux with different privileges

like -->

1> It can be accessible by telnet (or where i should check/change to give different privileges like telnet or ssh2 or FTP)

2> can run only 1 command / script

What UNIX operating system ?
Most unix/linux use "useradd" (aix uses mkuser) to add users.
As far as different privileges are concerned, many UNIX boxes do different things. For example most have a version of Role Based Access Control (RBAC). Or there are applications where you can define who can run what as a privileged user, for example Linux usually comes with "sudo". I hope this gives you some pointers where to start.

OKs i can work out on suggested

Can you tell me from where i can get virtual Unix/Linux machine on which i can do hands on?!! because i cannot experiments on my actual machines
