How to add/delete users?

Add user

Creating users let you :

Get a login for ssh access
Create a new mail address
Split privileges
...

According to the user's taks, you won't create the account the same way.

Leave defaults for an user with SSH access
You can add an user to a group to manage groups permissions for multiple user at once.
You can set a fake shell if you want to disable shell access for an user : "/sbin/nologin".

To add an user, use "adduser". It is interactive istead of "useradd". Yeah, I know...

That's how it looks like :

root@votreserveur[~] # adduser
Use option ``-silent'' if you don't want to see all warnings and questions.
Reading /etc/shells
Check /etc/master.passwd
Check /etc/group
Ok, let's go.
Don't worry about mistakes. There will be a chance later to correct any input.
