uuidd — UUID generation daemon
uuidd [−d] [ −p pidfile ] [ −s socketpath ] [ −T timeout ]
uuidd [ −r | −t ] [ −n number ] [ −s socketpath ]
uuidd \-k
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.
−dRun uuidd in debugging mode. This prevents uuidd from running as a daemon.
−kIf currently a uuidd daemon is running, kill it.
−n
numberWhen issuing a test request to a running uuidd,
request a bulk response of number UUIDs.
−p
pidfileSpecify the pathname where the pid file should be written. By default, the pid file is written to /var/run/uuidd/uuidd.pid.
−s
socketpathSpecify 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.
−rTest uuidd by trying to connect to a running uuidd daemon and request it to return a random-based UUID.
−tTest uuidd by trying to connect to a running uuidd daemon and request it to return a time-based UUID.
−T
timeoutSpecify a timeout for uuidd. If specified, then
uuidd will exit after timeout seconds of
inactivity.
−qTurn on quiet flag.
uuidd is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
