How does Solaris generate its 'hostid'? Is it a hardware/sparc thing, or
Generating a unique anonymous key is easy, proving why we need it is not.
Ok, here it is, " ifconfig | sha256 | md5 ". 16^32 unique anonymous
keys. Every host needs to have a NIC to send results so all ifconfig
outputs will be different. Now... What does this solve and why do we
need to add 32 extra bytes?
(20 + 32) bytes * (10^7) = 495.910645 megabytes. The FreeBSD team
would need a 6.6Mbit/s uplink to handle peak load assuming 50% of the
hosts are set to UTC/GMT time and all trigger within 5 minutes of each
other.... I'm not going to pay for that connection.
