7 uuidd \- UUID generation daemon
29 daemon is used by the UUID library to generate
30 universally unique identifiers (UUIDs), especially time-based UUID's
31 in a secure and guaranteed-unique fashion, even in the face of large
32 numbers of threads trying to grab UUID's running on different CPU's.
38 in debugging mode. This prevents uuidd from running as a daemon.
41 If a currently uuidd daemon is running, kill it.
44 When issuing a test request to a running uuidd, request a bulk response
50 Specify the pathname where the pid file should be written. By default,
51 the pid file is written to /var/run/uuidd/uuidd.pid.
54 Specify the pathname used for the unix-domain socket used by uuidd. By
55 default, the pathname used is /var/run/uuidd/request. This is primarily
56 for debugging purposes, since the pathname is hard-coded in the libuuid
60 Test uuidd by trying to connect to a running uuidd daemon and
61 request it to return a random-based UUID.
64 Test uuidd by trying to connect to a running uuidd daemon and
65 request it to return a time-based UUID.
68 Specify a timeout for uuidd. If specified, then uuidd will exit after
70 seconds of inactivity.
