Enabling Boot Messages on the Console
If you are not using a modem on the DB9 console port and instead
wish to connect to it directly via a Null Modem cable you may want to
enable verbose mode allowing you to see the standard linux start-up
messages. This can be achieved with the following commands:
# /bin/config --set=config.console.debug=on
# /bin/config --run=console
# reboot
If at some point in the future you chose to connect a modem for dial-
in out-of-band access the procedure can be reversed with the
following commands.
# /bin/config --del=config.console.debug
# /bin/config --run=console
# reboot
IP - Filtering
Standard IP-Filter configuration:
The system uses the iptables utility to provide a stateful firewall of LAN
traffic. By default, rules are automatically inserted to allow access to
enabled services, and serial port access via enabled protocols. The com-
mands which add these rules are contained in configuration files.
/etc/config/ipfilter
This is an executable shell script which is run whenever the LAN interface
is brought up and whenever modifications are made to the iptables con-
figuration as a result of CGI actions or the config command line tool.
