.SH DESCRIPTION |
|
The |
|
.B 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. |
|
.SH OPTIONS |
|
.TP |
|
.B \-d |
|
Run |
|
.B uuidd |
|
in debugging mode. This prevents uuidd from running as a daemon. |
|
.TP |
|
.B \-k |
|
If a currently uuidd daemon is running, kill it. |
|
.TP |
|
.BI \-n " number" |
|
When issuing a test request to a running uuidd, request a bulk response |
|
of |
|
.I number |
|
UUID's. |
|
.TP |
|
.BI \-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. |
|
.TP |
|
.BI \-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. |
|
.TP |
|
.B \-r |
|
Test uuidd by trying to connect to a running uuidd daemon and |
|
request it to return a random-based UUID. |
|
.TP |
|
.B \-t |
|
Test uuidd by trying to connect to a running uuidd daemon and |
|
request it to return a time-based UUID. |
|
.TP |
|
.BI \-T " timeout" |
|
Specify a timeout for uuidd. If specified, then uuidd will exit after |
|
.I timeout |
|
seconds of inactivity. |
|
.SH AUTHOR |
|
The |
|
.B uuidd |
|
daemon was written by Theodore Ts'o <tytso@mit.edu>. |
|
.SH AVAILABILITY |
|
.B uuidd |
|
is part of libuuid from the e2fsprogs package and is available from |
|
http://e2fsprogs.sourceforge.net. |
