Figure 36: Changing user password
When invoked without the
D
option, the
adduser
command creates a new user account using
the values specified on the command line plus the default values from the system. Depending on
command line options, the useradd command will update system files and may also create the new
user’s home directory and copy initial files.
passwd
change user password
The
passwd
command changes passwords for user accounts. A normal user may only change the
password for his/her own account, while the superuser may change the password for any account.
passwd
also changes the account or associated password validity period.
deluser
delete a user account and related files
The
deluser
command modifies the system account files, deleting all entries that refer to the user
name LOGIN. The named user must exist.
If a user intends to use newly created user account via both commandline
interface and web interface he should create and delete users via web interface
and not using
adduser
and
deluser
commands as they don’t create uci entries.
For more information about controlling users via command line interface one should refer to Linux
documentation.
21.1.3 Authentication via external service
WCC Lite support external authentification via RADIUS service. Remote Authentication DialIn User
Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization,
and Accounting (AAA or Triple A) management for users who connect and use a network service.
RADIUS is a client/server protocol that runs in the application layer, and can use either TCP or UDP as
transport. Network access servers, the gateways that control access to a network, usually contain a
RADIUS client component that communicates with the RADIUS server. RADIUS is often the backend
of choice for 802.1X authentication as well. The RADIUS server is usually a background process
running on a UNIX or Microsoft Windows server. In WCC Lite RADIUS Client is implemented since
WCC Lite software version v1.2.4. The user sends a request to a WCC Lite to gain access to get
access using access credentials posted in an HTTP/HTTPS WCCLite web login form.
This request includes access credentials, typically in the form of username and password.
Additionally, the request may contain other information which the Device knows about the user,
such as its network address or information regarding the user’s physical point of attachment to the
device. The RADIUS server checks that the information is correct using authentication schemes
