Terminal Server Configuration Without RealPort

In this configuration, Digi One/PortServer TS 2/4 functions as a terminal server, providing Telnet and Rlogin access to hosts. This configuration enables the following:

Telnet or Rlogin access to the LAN-based hosts, both from locally-connected terminals and from devices accessing the LAN from the telephone network.

Access for the LAN-based hosts to Digi One/PortServer TS 2/4 ports (sometimes called reverse Telnet)

Configuration Notes

1.The set config command configures the IP address and mask for the Digi One/PortServer TS 2/4 Ethernet interface.

2.The first set ports, set line, and set flow commands configure ports 1 and 2 for terminal connec- tions.

3.The next set ports, set line and set flow commands configure the ports for bidirectional modems. Software flow control (the default) is explicitly shut off and hardware flow control turned on using the set flow command.

4.The set user command defines a user, which assigns a user name for login purposes. All Digi One/PortServer TS 2/4 users can login with this name.
