Controlling Access to the Command Line
This section describes how to restrict access to the Digi One/PortServer TS 2/4 command line.
Method 1 Autoconnection
The autoconnection feature allows you to configure a user to access the Digi One/PortServer TS 2/4 but then be
automatically connected to a host on the LAN.
You can implement autoconnection in the following ways:
• By port. In this case, all port users are automatically connected to the same host. The Digi One/PortServer TS
2/4 is completely transparent to them.
• By user. In this case, a user is required to login and may be required to supply a password, but once the user is
authenticated, an automatic connection to a hosts made.
For information on configuring autoconnection, see "Configuring Autoconnection" on page 47.
Method 2: Menus
Menus select destination systems without having to access the Digi One/PortServer TS 2/4 command line. For
information on configuring menus, see the description of the set menu command in the Digi One/PortServer TS
Command Reference.

issuing a password.
Procedure
1. Issue a newpass command that identifies the user (on the name field) to whom this password will be issued.
