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/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.
