Figure 9-3 Checking FireScreen Installation Prerequisites
2. Click on Install.
3. At this point in the FireScreen installation, the following startup variables are added to the
/etc/rc.config file:
• SCREEND
Indicates whether the FireScreen daemon is to be started when the system is booted.
• SCREEND_FLAGS
Indicates which options are to be used when the FireScreen daemon is started on the
system.
• SCREEND_MODE
Indicates whether screening is on.
• SCREEND_KERNEL
Specifies the name of the kernel that contains support for the FireScreen daemon.
The FireScreen installation installs a startup script (/sbin/init.d/firescreen) to run
the FireScreen daemon when the system boots, and it links /sbin/rc3.d/S11firescreen
to /sbin/init.d/firescreen.
Note:
The FireScreen daemon and the system's routing daemon are started, in that order, when
the system boots. This guarantees that no IP packets are forwarded across the gateway before
FireScreen starts.
The /etc/inittab file is modified to set the default screening mode (on).
Finally, the default FireScreen configuration file, /etc/firescreen.conf, is installed
and the FireScreen reference pages are linked (assuming the OSFMANOS reference pages
subset is installed).
The default system configuration file and kernel are displayed.
