Hotwire is an integrated inventory system and a rapid deployment tool targeted at servicing enterprise environments. The currently supported rapid deployment technologies are Kickstart (Red Hat Linux), AutoYaST (SuSE Linux), and Preseed (Debian GNU/Linux). The hotwire server itself can be installed on any Linux platform, however. Additionally, where client machines have the python-dmidecode, func, and certmaster packages installed, hotwire is able to provide an automated inventory maintenance and dynamic updates, via funcwire, a hotwire tool.
PRADS is a "Passive Real-time Asset Detection System". It passively listens to network traffic and gathers information on hosts and services it sees. This information can be used to map your network, letting you know what services and hosts are alive and used. It can also be used together with your favorite IDS/IPS setup for "event to host/service" correlation. It can help you make sure that your inventory database is up to date. PRADS commes in two versions. One written in Perl, and one written in C. Some features might only be found in one of the versions.
