Applying an Optional Access Filter

An access filter is an input filter that restricts hosts users can log in to. Access filters
work as follows:
• The user logs in and specifies a host.
• The host address is compared against the access filter.
• If the address is permitted by the filter, the connection is established.
• If the address is not permitted, the connection is denied.
To apply an access filter to a login user, use the following command:
Command> set user Username ifilter [Filtername]
Note – You must define a filter in the filter table before you can apply it. For more
information about filters, see Chapter 8, "Configuring Filters."

Setting the Login Service Type

All login users must have an associated login service that determines the nature of their
connection with the host.
The login service specifies how login sessions are established. Four types of login
service are available as described in Table 5-4.

Login Host Options (Continued)
Description
This option allows the user to connect only to the host specifically
named. A valid 39-character hostname or IP address must be
entered.
This configuration is used when you want to allow a user to
access a specific host. For example, this configuration can be used
to allow the user carmela to always be connected with the host
sales.
Types of Login Service
Function
PortMaster is the default login service and can be used to access
any host that has the PortMaster in.pmd daemon installed. This
type of login service is preferred because it makes the PortMaster
port operate like a serial port attached to the host. This service is
the most cost-effective in terms of host resources.
