Accessing devices via modems using PPP, 122 | Black Box 24 port

Accessing devices via modems using PPP

For this method you will need to setup one of the serial ports for PPP (see Configuring a dial in line on page 74 in Chapter 3 System administration).

With a line configured for PPP you will be able to dial in for a PC using Microsoft's dial up networking.

A remote user will dial up by using dial up networking and once authenticated by the Console Server will be connected to the network. At this point a telnet session can be initiated as in the Accessing devices via Telnet from the LAN on page 117.

Note Even in the event of a main network failure a user will still be able to connect to the Console Server and access a port.
