UUIDD(8)                                                              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/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.

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

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