Operating the UC-8410/8416/8418/8430-CE

Computers via Telnet

Before operating your UC-8410/8416/8418/8430-CE computer using a Telnet client, we suggest that you

change the network settings of the computer (see an earlier section) so that at least one of the two network

ports is on the same LAN as your development workstation.

Use a cross-over Ethernet cable to connect your development workstation directly to the target computer, or

a straight-through Ethernet cable to connect the computer to a LAN hub or switch. Next, use the Telnet client

on your development workstation to connect to the Telnet console utility of the target computer. Once a

connection is established, type the login name and password as requested to log on to the computer.

After logging in via the console port or a Telnet client, several busybox commands are available to operate the

computer. Use HELP to display all of the commands, or type HELP [command name] to display extended

help for the selected command. Some of the commands, such as DATE and TIME are very useful for managing

the computer’s the 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, simply type DIR.

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 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.
