Statistics

Services in general; Apache, Bind, Exim and the Firewall.
IPv6 statistics
Firewall Statistics for sput.nl
Non existent file statistics
HTTP 404 response code. A lot of these files (not all) are requested hoping to compromise the system.
NTP statistics
Rejected mail statistics
Failed SMTP login Statistics for sput.nl
Persistent crooks get added to the firewall. Individual IP addresses may be aggregated to IP address ranges.
WAN Statistics
RFC 1918 on wan
This stuff really shouldn't be there.

The IPv6 and NTP stats are made with RRDtool.
For the other stats the logfiles are converted to fake http logs and then fed to Analog. The fake logs are preprocessed to deal with Analog's IPv6 incompatibility. Unresolved IPv6 addresses show up as a fake '.ipvsix' TLD in the pie charts. In lists they are grouped by /32 and /48.

Location

Leiden, The Netherlands.
So that's NOT Amsterdam, Castricum, Den Haag, Diepenveen, Etten, Hilversum, Leiderdorp, Leidschenveen, Roelofarendsveen, Utrecht, Ypenburg, Zoetermeer or Zutphen, as some sites claim;
Geolocation databases are notoriously inaccurate and outdated. Using them causes a lot of trouble!
