Snort rules ------------------------------------------------------------------------------ The Debian package of fwsnort does not contain any ruleset. However, you can get the latest Emerging Threats rules from http://www.emergingthreats.net by running one of the following commands: fwsnort --update-rules or dpkg-reconfigure fwsnort The new ruleset will be saved in /etc/fwsnort/snort_rules. By using dpkg-reconfigure to update the rules, your choice will be saved. Then, for each upgrade of the package the rules will be updated. If you decide you do not want this feature anymore, you can simply reconfigure fwsnort with dpkg-reconfigure, and change your choice to No. The snort-rules-default package is recommended and can provide you with more rules that you can then manage by oinkmaster. If you handle rulesets from different directories (for example to use both the rules from Emerging Threats and the ones from the snort-rules-default package) then you can run this command: fwsnort --snort-rdir /etc/snort/rules,/etc/fwsnort/snort_rules You can add as many directories as you want as a comma separated list.
