He's trying to prevent any possibility of information disclosure about
his servers. If I wanted to hack into his site, knowing what hosts he
had running (ie. a bunch of live IP numbers) and what OS etc. each used
would mean I'm already halfway to my goal. Now, while the design of
bsdstats does not disclose that sort of stuff readily, any security
conscious admin is going to worry about that data being collected and
held outside of his administrative control. Having a completely
anonymous and untraceable token to identify each of the hosts sending
in information should make connecting the information back to the
original sender practically impossible.
Although, playing devil's advocate here, anyone that could steal the
Apache log files from the bsdstats server would be able to work out
that sort of data fairly readily. I guess the truly paranoid should
only submit their data via some sort of anonymizing proxy.
Cheers,
Matthew
