| 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. | |
