Clicking Finish on the Activate the
Firewall page will write the firewall rules to
/etc/sysconfig/ipchains and start the firewall by
starting the ipchains service.
It is highly recommended that you run GNOME
Lokkit from the machine, not from a remote X session. If
you disable remote access to your system, you will no longer be able to
access it or disable the firewall rules.
Click Cancel if you do not want to write the
firewall rules.
A mail relay is a system that allows other systems to send email
through it. If your system is a mail relay, someone can possibly use it
to spam others from your machine.
If you chose to enable mail services, after you click
Finish on the Activate the
Firewall page, you will be prompted to check for mail
relay. If you choose Yes to check for mail
relay, GNOME Lokkit will attempt to connect
to the Mail Abuse Prevention System website at
http://www.mail-abuse.org/
and run a mail relay test program. The results of the test will be
displayed when it is finished. If your system is open to mail relay,
it is highly recommended that you configure Sendmail to prevent it.
The firewall rules will only be active if the
ipchains service is running. To manual start the
service, use the command:
/sbin/service ipchains restart |
To ensure that it is started when the system is booted, issue the
command:
/sbin/chkconfig --level 345 ipchains on |
