NAME

6       uuidd - UUID generation daemon
7

SYNOPSIS

9       uuidd [-d] [-p pidfile] [-s socketpath] [-T timeout]
10       uuidd [-r|-t] [-n number] [-s socketpath]
11       uuidd -k
12

DESCRIPTION

14       The  uuidd  daemon  is used by the UUID library to generate universally
15       unique identifiers (UUIDs), especially time-based UUIDs,  in  a  secure
16       and  guaranteed-unique  fashion,  even  in the face of large numbers of
17       threads running on different CPUs trying to grab UUIDs.
18

OPTIONS

20       -d     Run uuidd in debugging mode.  This prevents uuidd  from  running
21              as a daemon.
22
23       -k     If currently a uuidd daemon is running, kill it.
24
25       -n number
26              When  issuing  a test request to a running uuidd, request a bulk
27              response of number UUIDs.
28
29       -p pidfile
30              Specify the pathname where the pid file should be  written.   By
31              default, the pid file is written to /var/run/uuidd/uuidd.pid.
32
33       -s socketpath
34              Specify  the  pathname  used  for the unix-domain socket used by
35              uuidd.  By default, the pathname used is /var/run/uuidd/request.
36              This  is primarily for debugging purposes, since the pathname is
37              hard-coded in the libuuid library.
38
39       -r     Test uuidd by trying to connect to a running  uuidd  daemon  and
40              request it to return a random-based UUID.
41
42       -t     Test  uuidd  by  trying to connect to a running uuidd daemon and
43              request it to return a time-based UUID.
44
45       -T timeout
46              Specify a timeout for uuidd.  If specified, then uuidd will exit
47              after timeout seconds of inactivity.
48
49       -q     Turn on quiet flag.
