Controlling Access to Inbound Ports
Chapter 12 Configuring Security Features 60
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 are required 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:
set logins range=range login=off passwd=off
Example: set logins range=1-2 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:
set user name=name password=off
where name is a name to identify the user
Example: set user name=user1 password=off
Controlling Access to Outbound Ports
This section describes methods for controlling access to outbound serial ports. An outbound port is one defined
on the dev field of the set ports command for one of the following device types:
• prn (used to define printer connections)
• mout (used to define outbound modem connections
• mio (used to define bi-directional modem connections)
• host (used to define host connections)
