[rhelv6-list] what does hostid return?

[Mirko Vukovic]

Hello,

A software vendor asked me to provide a hostid for a software license.

I typed in hostid, got an eight digit hexadecimal number and emailed it to
them.

However, they were looking for a 12 digit hex number.

I sent them the hardware address of eth0.

My question is: how is the hostid number obtained?  Is it from a disk
drive, or some other hardware.  I could not find information online.

Thank you,

Mirko
