Nipper – network infrastructure configuration parser
Network Infrastructure Parser (Nipper) is software that can assist during firewall and router security configuration reviews. The software will identify security weaknesses in device configurations and highlight configuration settings that should be focussed on during the further manual review process.
Since the Nipper 0.11.x release series the Nipper author has included commercial use clauses in its license. Although Nipper was still released under GPL, the author did include additional clauses which is not allowed by the GPL licensing model:
Section 10 of the GPLV3: "You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License."
Nevertheless, it is not because the author does not mind software licensing infrigments, that we don’t have to. Those who still want to use Nipper for commercial purposes but do not want to pay for the software will need to look into versions older than version 0.11.x. Home users will be able to continue to use the latest Nipper versions for free. The author has removed all old versions from the Nipper sourceforge page. If you want to download the latest Nipper version that is not subject to the commercial limitations, version Nipper 0.10.0 can be downloaded from PacketStorm.
