Done ... now I really hope that the US stats rise, maybe? I have a hard
time believing that Russia and the Ukraine have more deployments then the
'good ol'US of A' ... or do they? *raised eyebrow*
Here is what is now stored in the database (using my IP as a basis)
# select * from systems where ip = md5('24.224.179.167');
id | ip | hostname |
operating_system | release | architecture | country | report_date

Why don't you just broadcast the ip address, it's what your doing now
anyways. 253^4 is a very small number.
infomatic# perl
my $num = 0;
system "date";
while ($num <= 409715208) {
$num++
}
system "date";

2 minutes * 10 = 20 minutes to iterate though 4 billion IP addresses
on a very slow uni-proc system. I could even store every IP to md5
hash using less then 222GB of uncompressed space.
If you want... give me the md5 hash of a real ip address that is
unknown to me and I will hand you the ip address in two days... or
less. run the IP address though like this:
md5 -s "xxx.xxx.xxx.xxx"
I have other things to do with my time, so I don't really want to do
this, but if that's what it takes to stop this idea dead I'll do it.
