Controlling Access to Inbound Ports

This section describes methods of controlling access to inbound serial ports. An inbound port is one defined on the dev field of the set ports command for one of the following device types:

• term (used to define terminal connections)
• min (used to define incoming modem connections)
• mio (used to define bi-directional modem connections)
• hdial, hio (used to define computer connections)

Default Access Restrictions

The default configuration for inbound ports is that a login and password are required to access them.

Options for Removing Access Restriction

The login and password requirement for inbound ports can be changed by configuring

• The port so that it does not require a login and password. In this case, no one is required to supply a login or password.
• Specific users so that they do not require a password. In this case, some users do not supply passwords, and others may have to.

Procedure for Changing a Port's Access Requirements

To configure a port so that no one has to login or specify a password, supply a set logins command that specifies the following:

• The port or ports configured by this command (on the range field)
• login=off
• passwd=off

Example: set logins range=4-6 login=off passwd=off

Procedure for Changing a User's Access Requirements

To configure a user so that he or she does not have to specify a password when accessing an inbound port, supply a set user command that specifies the following:

• A name to identify the user (on the name field)
• password=off

Example: set user name=user1 password=off
