UUIDD(8) System Manager's Manual 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 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. AUTHOR
The uuidd daemon was written by Theodore Ts'o <tytso@mit.edu>. AVAILABILITY
uuidd is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. SEE ALSO
