UUIDD(8)		     System Administration		      UUIDD(8)

NAME
       uuidd - UUID generation daemon

SYNOPSIS
       uuidd [options]

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.

       -h, --help
	      Display help screen and exit.

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

       -n, --uuids number
	      When  issuing  a test request to a running uuidd, request a bulk
	      response of number UUIDs.

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

       -q     Suppress some failure messages.

       -r, --random
	      Test  uuidd  by  trying to connect to a running uuidd daemon and
	      request it to return a random-based UUID.

       -s, --socket path
	      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.

       -T, --timeout timeout
	      Specify a timeout for uuidd.  If specified, then uuidd will exit
	      after timeout seconds of inactivity.

       -t, --time
	      Test uuidd by trying to connect to a running  uuidd  daemon  and
	      request it to return a time-based UUID.

       -V, --version
	      Output version information and exit.

EXAMPLE
       Start up a daemon, print 42 random keys, and then stop the daemon.

	      uuidd -p /tmp/uuidd.pid -s /tmp/uuidd.socket
	      uuidd -d -r -n 42 -s /tmp/uuidd.socket
	      uuidd -d -k -s /tmp/uuidd.socket

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

AVAILABILITY
       The  uuidd  daemon  is  part of the util-linux package and is available
       from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
