42 | .SH DESCRIPTION | |
43 | The | |
44 | .B uuidd | |
45 | daemon is used by the UUID library to generate | |
46 | universally unique identifiers (UUIDs), especially time-based UUID's | |
47 | in a secure and guaranteed-unique fashion, even in the face of large | |
48 | numbers of threads trying to grab UUID's running on different CPU's. | |
49 | .SH OPTIONS | |
50 | .TP | |
51 | .B \-d | |
52 | Run | |
53 | .B uuidd | |
54 | in debugging mode. This prevents uuidd from running as a daemon. | |
55 | .TP | |
56 | .B \-k | |
57 | If a currently uuidd daemon is running, kill it. | |
58 | .TP | |
59 | .BI \-n " number" | |
60 | When issuing a test request to a running uuidd, request a bulk response | |
61 | of | |
62 | .I number | |
63 | UUID's. | |
64 | .TP | |
65 | .BI \-p " pidfile" | |
66 | Specify the pathname where the pid file should be written. By default, | |
ebf5fb2b | 67 | the pid file is written to /var/lib/libuuid/uuidd.pid. |
740837de TT |
68 | .TP |
69 | .BI \-s " socketpath" | |
70 | Specify the pathname used for the unix-domain socket used by uuidd. By | |
ebf5fb2b | 71 | default, the pathname used is /var/lib/libuuid/request. This is primarily |
740837de TT |
72 | for debugging purposes, since the pathname is hard-coded in the libuuid |
73 | library. | |
74 | .TP | |
75 | .B \-r | |
76 | Test uuidd by trying to connect to a running uuidd daemon and | |
77 | request it to return a random-based UUID. | |
78 | .TP | |
79 | .B \-t | |
80 | Test uuidd by trying to connect to a running uuidd daemon and | |
81 | request it to return a time-based UUID. | |
82 | .TP | |
83 | .BI \-T " timeout" | |
84 | Specify a timeout for uuidd. If specified, then uuidd will exit after | |
85 | .I timeout | |
86 | seconds of inactivity. | |
87 | .SH AUTHOR | |
88 | The | |
89 | .B uuidd | |
90 | daemon was written by Theodore Ts'o <tytso@mit.edu>. | |
91 | .SH AVAILABILITY | |
92 | .B uuidd | |
93 | is part of libuuid from the e2fsprogs package and is available from | |
94 | http://e2fsprogs.sourceforge.net. | |
