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 UUID's	 in  a	secure
       and  guaranteed-unique  fashion,	 even  in the face of large numbers of
       threads trying to grab UUID's running on	different CPU's.

OPTIONS
       -d     Run uuidd	in debugging mode.  This prevents uuidd	 from  running
	      as a daemon.

       -k     If a currently uuidd daemon is running, kill it.

       -n number
	      When  issuing  a test request to a running uuidd,	request	a bulk
	      response of number UUID's.

       -p pidfile
	      Specify the pathname where the pid file should be	 written.   By
	      default, the pid file is written to /var/lib/libuuid/uuidd.pid.

       -s socketpath
	      Specify  the  pathname  used  for	the unix-domain	socket used by
	      uuidd.  By default, the pathname	used  is  /var/lib/libuuid/re-
	      quest.   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.

AUTHOR
       The uuidd daemon	 was written by	Theodore Ts'o <tytso@mit.edu>.

AVAILABILITY
       uuidd  is  part	of libuuid from	the e2fsprogs package and is available
       from http://e2fsprogs.sourceforge.net.
