RadiusReport can analyse the logfiles produced by all the major Radius Servers including Livingston Radius V2.0+, V1.16, Merit Radius, Ascend Radius, Dale Reed's RadiusNT, Radiator Perl Radius Server, but excluding Microsoft Radius. It will allow you to produce many, varied, types of reports from one or multiple radius log files.
DummyIdentd Server Daemon is a Perl program that accepts identd requests (port 113), and responds with a valid response, but giving out no useful information. It is written in Perl, and is suitable for running on company gateways/firewalls to enable your users to access services such as IRC, which require identd.
RadiusSplit is a Perl program designed to take, as input, one or more large RADIUS accounting "detail" log files, and split them out into individual files - one per user. The net result is that you will have a detail file per user, which can be passed to other RADIUS parsing logfile analysers (e.g. RadiusReport) so they run much faster (usually be a factor of several hundred), since they don't have to parse and discard the non-relevant data.
YAcY is a badly behaved robot
1. YAcY doesnt ask for robots.txt, let alone follow it.
2. YAcY posts the yacy web address as the HTTP Refer[r]er header similar to spam bots. Well behaved bots may put their url into the Agent header.
I only came across this project whilst researching against HTTP Referrer spammers, nice idea - shame about the implementation.
