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/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.
