User/Group Management 
User Group: You should assign specific services, such as ftp and telnet, to defined user groups 
such that these services are accessible only by the users within the permissible user group. Three 
user groups, namely “ftpd”, “telnetd”, and “httpd”, are already created by default for your 
convenience. 
Adding a Group: Use the command useradd –g <groupName> to create a user group. 
\> useradd –g yyyy 
group yyyy has been added. 
Deleting a Group: To remove a group, use the command userdel –g <groupName>. 
\> userdel –g yyyy 
group yyyy has been removed. 
Adding a User: Use the command useradd <newUserID> to add a user for accessing the system. 
The user’s password, by default, is the same as the user name. 
\> useradd xxxx 
user xxxx has been added. 
In addition, you can permit this user to access a particular service by typing -g followed by the 
user group name of the service, i.e., useradd –g <groupName> <newUserID>. For example, 
\> useradd –g telnetd xxxx 
user xxxx is existent 
group telnetd is existent 
user xxxx has been added to group yyyy 
Deleting a User: Use the command userdel <userID> to delete a user from the system. User 
“admin” CANNOT be deleted. 
\> userdel xxxx 
user xxxx has been deleted 
You can also just remove a user from a user group by using the command userdel –g 
<groupName> <newUserID>. For example, 
\> userdel –g yyyy xxxx 
user xxxx has been removed from group yyyy 
Changing the Password: Please use “System Manager” to change the Password.
