User/Group Management
User Grouping: You often need to define a user group to associate with a particular system
service and manage this service to be accessible only by the users authorized to register with this
group. Three user groups, namely ftpd, telnetd, and httpd, have been created in the default
factory kernel for your convenience.
Use command “useradd –g <groupName>” to create a user group.
\> useradd –g yyyy
group yyyy has been added.
To remove a group, use the command “userdel –g <groupName>“.
\> userdel –g yyyy
group yyyy has been removed.
User Addition: Use the command “useradd <newUserID>“ to add a user for accessing the
system. The user’s password is defaulted to the same as the user name.
\> useradd xxxx
user xxxx has been added.
In addition, you can manage 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
User Deletion: Use command “userde <userID>l” to delete a user for accessing 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 with the command “userdel –g <groupName>
<newUserID>”. For example,
