UUIDD(8) FreeBSD 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 UUID's in a secure and guaranteed-unique fashion, even in the face of large numbers of threads trying to grab UUID's running on different CPU's. OPTIONS -d Run uuidd in debugging mode. This prevents uuidd from running as a daemon. -k If a currently uuidd daemon is running, kill it. -n number When issuing a test request to a running uuidd, request a bulk response of number UUID's. -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. AUTHOR The uuidd daemon was written by Theodore Ts'o <tytso@mit.edu>. AVAILABILITY uuidd is part of libuuid from the e2fsprogs package and is available from http://e2fsprogs.sourceforge.net. SEE ALSO libuuid(3), uuidgen(1)
