uuidd
UUIDD(8) System Administration UUIDD(8)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.
-h, --help
Display help screen and exit.
-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, --pid path
Specify the pathname where the pid file should be written. By default, the pid file is written to /var/uuidd/uuidd.pid.
-P, --no-pid
Do not create pid file.
-F, --no-fork
Do not daemonize using double-fork.
-S, --socket-activation
Do not create the socket and instead expect it to be provided by the calling process. Implies --no-fork and --no-pid. As of this
writing, this option is supposed to be used only with systemd. This option must be enabled with a configure option.
-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 path
Specify the pathname used for the unix-domain socket used by uuidd. By default, the pathname used is /var/uuidd/request. This is
primarily for debugging purposes, since the pathname is hard-coded in the libuuid library.
-T, --timeout timeout
Specify a timeout for uuidd. If specified, then uuidd will exit after timeout 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.
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
AUTHOR
The uuidd daemon was written by Theodore Ts'o <tytso@mit.edu>.
AVAILABILITY
The uuidd daemon is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
