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 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.
|
−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.
The uuidd daemon was written by Theodore Ts’o <tytso@mit.edu>.
uuidd is part of libuuid from the e2fsprogs package and is available from http://e2fsprogs.sourceforge.net.
