UUIDD(8)               DragonFly 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/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.
