I’ve got a bunch of servers running this Linux app. I’d like for them to be able to generate a GUID with a low probability of collision. I’m sure I could just pull 128 bytes out of /dev/urandom and that would probably be fine, but is there a simple & easy way to generate a GUID that is more equivalent to the Win32 one? Specifically, one that takes into account space (well, MAC address), time, and randomness? I don’t want to call off the box for it, I just want something like CreateGuid()

  1. This Internet Draft describes one type of UUID in great details and I have used a similar approach with great success when I needed a UUID implementation and could not link to an existing library for architectural reasons.

    This article provides a good overview.
