7 | ### Features
8 |
9 | * Simple
10 | * Single binary; Tiny Docker image
11 | * Classic write-only "drop box"; No file reads ever
12 | * Renames files, not overwrite, by default
13 |
14 | ### Install
15 |

50 | 2015/06/24 01:10:59 #0001 received 53B
51 | ```
52 |
53 | ### CLI Usage
54 |
55 | ```
56 | Usage: uploader [options]
57 |
58 | note: udp creates files using a stream of packets. udp packets are not authenticated,
59 | so it's highly recommended that you set an allowed-ip range to prevent misuse.
60 | udp packets are all appended to a file called 'md5(:).bin'.
61 | udp streams are considered closed after --udp-close and the file will be closed.
62 |
63 | Options:
64 | --dir, -d output directory (defaults to tmp)
65 | --overwrite, -o duplicates are overwritten (auto-renames files by default)
66 | --auth, -a require basic auth 'username:password' on http connections
67 | --port, -p tcp listening port (default 3000)
68 | --udp-port, -u udp listening port (default disabled)
69 | --udp-close close udp file after timeout (default 2s)
70 | --no-log, -n disable http request logging
71 | --allowed-ip, -i allowed ip range (allows multiple)
72 | --verbose, -v enable verbose logging
73 | --version display version
74 | --help, -h display help
75 |
