Control Access to Outbound Ports
An outbound port is one defined on the “set ports” “dev” option, where
“dev” is set to one of the following device types:
• “prn” for printer connections.
• “mout” for outbound modem connections.
• “mio” for bi-directional modem connections.
• “host” for host connections.
• “ia” for industrial automation devices.
The default for outbound ports is unlimited access.
Restrict Access to Outbound Ports
Use the “set auth” command to restrict access to outbound ports. See
"set auth" on page 90.
Use CHAP Authentication for PPP Users
CHAP authentication can be used to restrict PPP user access to outbound
ports. For more information on CHAP configuration, see "set user" on page
230.
Control User Access to the Command Line
You can restrict user access to the device server command line through the
following methods:
• Using the autoconnection feature
• Using menus
Using the Autoconnection Feature
The autoconnection feature allows you to configure a user to access the
device server but then be automatically connected to a host on the LAN.
You can implement autoconnection in the following ways:
• By port, where all port users are automatically connected to the same
host. The device server is completely transparent to them. Use the
“set ports” command, with the “auto,” “autoservice,” “dest,” “dev,” and
“dport” options. See "set ports" on page 169.
• By user, where 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 host is made. Use the “set user” command, with the
“name,” “autoconnect,” “autohost,” “autoport,” and “defaultaccess”
options. See "set user" on page 230.
Using Menus
Menus select destination systems without having to access the device
server command line. Menus are created using the set menu command.
For information on configuring menus, see "set menu" on page 159.
