Telnet Configuration and Capabilities

This chapter covers the Telnet Configuration and Capabilities of the Prestige.

12.1 About Telnet Configuration

Before the Prestige is properly setup for TCP/IP, the only option for configuring it is through the console port. Once your Prestige is configured, you can use telnet to configure it remotely as shown below.

12.2 Telnet Under NAT

When Network Address Translation (NAT) is enabled and an inside server is specified, telnet connections from the outside will be forwarded to the inside server. So to configure the Prestige via telnet from the outside, you must first telnet to the inside server, and then telnet from the server to the Prestige using its inside LAN IP address. If no inside server is specified, telnetting to the NAT’s IP address will connect to the Prestige directly.

12.3 Telnet Capabilities

12.3.1 Single Administrator

To prevent confusion and discrepancy on the configuration, your Prestige only allows one administrator to log in at any time. Your Prestige also gives priority to the console port over telnet. If you have already connected to your Prestige via telnet, you will be logged out if another user logs in to the Prestige via the console port.
