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, --debug
              Run uuidd in debugging mode.  This prevents uuidd from running as a daemon.

       -F, --no-fork
              Do not daemonize using a double-fork.

       -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, --no-pid
              Do not create a pid file.

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

       -q, --quiet
              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-activation
              Do not create a socket but instead expect it to be provided by the calling process.
              This  implies --no-fork and --no-pid.  This option is intended to be used only with
              systemd(1).  It needs to be enabled with a configure option.

       -s, --socket path
              Make uuidd use this pathname for the unix-domain socket.  By default, the  pathname
              used is /run/uuidd/request.  This option is primarily for debugging purposes, since
              the pathname is hard-coded in the libuuid library.

       -T, --timeout number
              Make uuidd exit after number 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.

       -h, --help
              Display help screen 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
