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 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.

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

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

       -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.

       -q     Turn on quiet flag.
