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 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/run/uuidd/uuidd.pid. -q 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/run/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
