On a freshly installed system the files "oinkmaster-enabled-sids.conf" and "oinkmaster-disabled-sids.conf" located in "/var/ipfire/suricata" are missing when downloading any ruleset the first time. Download of the ruleset tarball works fine, but oinkmaster does not launch because of this two missing files. Therefore the ruleset could not be extracted and used!
Add them to the rootfile then?
