Telnet
AN ALTERNATIVE WAY TO INTERFACE
A terminal-style configuration is available via
Telnet.
If you are on a non-Windows operating system (like Linux), you
will have to use Telnet. WinDiscovery is configured only for the
Windows operating system.
Use any standard Telnet client application and specify the IP
address of the device as the server with which to connect. The
factory default is Telnet server port 23.
Access the Telnet configuration by clicking the [
Communications
Control
] button on the “
Device Settings
” window (at left).
The following sections provide basic descriptions of using the
Telnet interface of the network device. Please refer to the
previous WinDiscovery section (p. 14) for additional details and
important operational information regarding the special
features and modes of the network device.
TO INITIATE A TELNET SESSION
Select the [
Run
] command-line interface from the Start menu
and enter the command “
telnet
” followed by a space, and then
the IP address of the unit and click [
OK
].
At the login prompt, type the user name and press the [
Enter
] or
[
Return
] key. Next you will be prompted to type the password.
The factory default for both user name and password are:
“public”.
To initiate commands, type the desired command name and
press the [
Enter
] or [
Return
] key.
At left a sample window from Telnet.
Configuration via
Telnet
may not be convenient
for devices operating with a factory default
configuration since the IP address is not known.
Use the
WinDiscovery
application to establish
first-time networking configuration.
For security purposes, the
Telnet
interface can
be disabled. When disabled, you will no longer
be able to access the device with
Telnet
.
To re-enable the Telnet feature, one of the other
configuration methods must be used, or the
device must be reset to factory default.
If you are not familiar with
Telnet,
ask your
network administrator for assistance.
Current configuration or default answers are
displayed in brackets. Depressing the
[
Enter
]/[
Return
] key with no number or letter
will retain the current setting.
Telnet is a 40-year-old network protocol used on
the Internet or local area networks to provide a
bidirectional interactive text-oriented
communication facility using a virtual terminal
connection.
