OK, I've used various versions of UNIX(Solaris, HPUX, etc..) over the years. Now the organization I work for is leaning towards more Linux based systems(Redhat, Suse, etc..)

So, what is it... (5 Replies)

uuidd
UUIDD(8) System Manager's Manual UUIDD(8)NAME
uuidd - UUID generation daemon
SYNOPSIS
uuidd [-d] [-p pidfile] [-s socketpath] [-T timeout]
uuidd [-r|-t] [-n number] [-s socketpath]
uuidd -k
DESCRIPTION
The uuidd daemon is used by the UUID library to generate universally unique identifiers (UUIDs), especially time-based UUIDs, in a secure
and guaranteed-unique fashion, even in the face of large numbers of threads running on different CPUs trying to grab UUIDs.
OPTIONS -d Run uuidd in debugging mode. This prevents uuidd from running as a daemon.
-k If currently a uuidd daemon is running, kill it.
-n number
When issuing a test request to a running uuidd, request a bulk response of number UUIDs.
-p pidfile
Specify the pathname where the pid file should be written. By default, the pid file is written to /var/run/uuidd/uuidd.pid.
-s socketpath
Specify the pathname used for the unix-domain socket used by uuidd. By default, the pathname used is /var/run/uuidd/request. This
is primarily for debugging purposes, since the pathname is hard-coded in the libuuid library.
-r Test uuidd by trying to connect to a running uuidd daemon and request it to return a random-based UUID.
-t Test uuidd by trying to connect to a running uuidd daemon and request it to return a time-based UUID.
-T timeout
Specify a timeout for uuidd. If specified, then uuidd will exit after timeout seconds of inactivity.
-q Turn on quiet flag.
AUTHOR
The uuidd daemon was written by Theodore Ts'o <tytso@mit.edu>.
AVAILABILITY
uuidd is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
