uuidd - helper daemon to guarantee uniqueness of time-based UUIDs… more info»
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 uni‐
versally 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/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.
-q Turn on quiet flag.
