5.9 Access via Telnet

The PS/2 KVM over IP switch firmware features a Telnet server that enables a user to connect via a standard Telnet client. It is used for passthrough access to a device possibly connected to the serial port 1. This means you may connect any serial device which offers terminal access via its serial port to PS/2 KVM over IP switch and access it using the Telnet interface. Set the serial settings (see Section 5.6) according to the requirements of the device.

Connecting to PS/2 KVM over IP switch is done as usual and as required by the Telnet client, for instance in a UNIX shell:

telnet 192.168.1.225

This will prompt for username and password in order to log into the card. The credentials that need to be entered for authentication are identical to those of the web interface. That means, the user management of the Telnet interface is entirely controlled with the according functions of the web interface.

Once you have successfully logged in PS/2 KVM over IP switch will present you the command line where you can enter according management commands.

In general, the Telnet interface supports two operation modes: the command line mode and the terminal mode. The command line mode is used to control or display some parameters. In terminal mode the pass-through access to serial port 1 is activated (if the serial settings were made accordingly). All inputs are redirected to the device on serial port 1 and its answers are displayed at the Telnet interface

The following list shows the according command mode command syntax and their usage.
