Clearly, someone wanting to generate a true universally unique identifier (someone like myself, for instance) would be using the time-based option of a Linux uuidgen. It is this type of securely-generated UUID that I am interested in. Does anyone on this list know if FreeBSD has such a utility/libraries, or am I simply doomed to be subjected to more of Mr. Nelson's tangental smarty-pants replies about jot random number generation? > -----Original Message----- > From: Dan Nelson [SMTP:dnelson@emsphone.com] > Sent: Wednesday, May 24, 2000 3:44 PM > To: TEMPLE, MATTHEW (LNG) > Cc: 'freebsd-questions@freebsd.org'; MITZKA, JOHN (LNG) > Subject: Re: uuidgen or other GUID-generating utility > > In the last episode (May 24), TEMPLE, MATTHEW (LNG) said: > > Ok...SunOS 5.5.1 does have a uuidgen and Linux's uuidgen does not > > simply spit out a random string.
