W406-CE User’s Manual
Getting Started
Operating Your W406 Computer through a Telnet Client
Use a cross-over Ethernet cable to connect directly from your development workstation to the
W406 computer, or use a straight-through Ethernet cable to connect the computer to a LAN hub or
switch. Next, use the Telnet client in your development workstation to connect to the Telnet
console utility of the W406 computer. After connecting successfully, type the login name and
password as requested to log on to the computer.
Login: admin
Password: admin
After logging on through the console port or through a Telnet client, a list of commands are
available to operate the computer. Use “HELP” to display all of the commands and type “HELP
[command name]” to display extended help for the given command. Some of these commands,
such as “DATE” and “TIME” are very useful for managing the computer’s system time. Other
commands, such as “DIR” and “MKDIR” are good utilities for file management. For example, to
inspect the file structure of the root directory, type
DIR
.
> dir /b

User/Group Management
User Group:
You should assign specific services, such as ftp and Telnet, to defined user groups
so 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 to 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
