Using Model 5390 Security
5
When authentication is complete, have the user issue the CLI ipx command. This sets
the port mode to ipx and connects the user to the Novell network.
IPX users connected to a port that is administratively set to ipx, ndp, auto_detect, or auto_adapt
cannot be prompted for more than one password, nor can they receive a CHALLENGE.
For information on configuring SafeWord, see Using SafeWord Security on page A15-64.
Other ACP Security Mechanisms
In addition to password authentication, ACP also provides dial-back security, charge-back
privileges, and security logging.
Dial-back
The dial-back feature increases network security by ensuring that particular users connect to the
Model 5390 server via authorized phone numbers. With dial-back, the Model 5390 server
automatically responds to a dial-in attempt by calling the user back at a predefined telephone number.
You can assign up to nine dial-back numbers for each user. FastLink II software provides a field in
which the user specifies a number from the set of numbers you assign.
The Model 5390 server connects the user to one of a set of ports that you reserve for dial-in, and
then calls the user back on one of a set of ports that you reserve for dial-back. By reserving different
ports for dial-in and dial-back, you avoid tying up dial-in ports for long periods of time.
To configure dial-back:
1
Make sure the Model 5390 enable_security parameter is set
to Y.
2
For the incoming port:
a)
Set the mode parameter to ipx, auto_detect, or auto_adapt.
b)
Set ipx_security to Y.
c)
Set the type_of_modem parameter to the modem type attached to the port (for example,
USR_144). This value must match the type_of_modem field in the Model 5390
configuration file, which resides on the host from which your Model 5390 server boots
and is named (by default) config.annex.
NOTE:
Dial-back is referred to as call-back in all documentation for
the Annex DOS Dial-out software and the FastLink II software.
