.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.
|
