4. Serial Port, Host, Device and User Configuration
Logging Level This specifies the level of information to be logged and monitored (refer to 7. Alerts and Logging).
Telnet When the telnet service is enabled on the console server, a telnet client on a User’s or Administrator’s
computer can connect to a serial device attached to this serial port on the console server. The telnet
communications are unencrypted so this protocol is generally recommended only for local or VPN tunneled
connections.
With Win2000/XP/NT, you can run telnet from the command prompt (cmd.exe). Windows Vista and later ships
with a telnet client but it is not enabled by default. You can install it by following the simple steps below.
o Click the Start button , click Control Panel, click Programs, and then click Turn Windows Features
On or Off . If you are prompted for an administrator password or confirmation, type the password or
provide confirmation.
o In the Windows Features dialog box, select the Telnet Client check box.
o Click OK. The installation might take several minutes.
If remote communications are being tunneled with SDT Connector, then telnet can be used for securely
accessing these attached devices.
Note: In Console Server mode, Users and Administrators can use SDT Connector to set up secure telnet connections that are SSH tunneled
from their client computers to the serial port on the console server. The SDT Connector can be installed on Windows PCs and on most Linux
platforms. It enables secure telnet connections to be selected with a simple point-and-click.
To use SDT Connector to access consoles on the console server serial ports, configure the SDT Connector with the console
server as a gateway, then as a host. Then enable telnet service on Port (2000 + serial port #) i.e. 2001–2048. Refer to 6.
SSH Tunnels and SDT Connector for more details on using the SDT Connector for telnet and SSH access to devices that are
attached to the console server serial ports.
