4 #
5 # A script that can communicate with jungo-based routers
6 # (such as MI424-WR, USR8200 and WRV54G) to backup the installed
7 # firmware and replace the boot loader.
8 #
9 # Tested with Python 2.5 on Linux and Windows
10 #
11 """Usage: %s [options] <IP_address> [image.bin | url]
12 Valid options:
13 \t-h | --help: usage statement
14 \t-d | --dump: create a flash dump
15 \t-f | --file: use <filename> to store dump contents
16 \t-u | --user: provide username (default admin)
17 \t-p | --pass: provide password (default password1)
18 \t --port: set port for http (default 8080)
19 \t-q | --quiet: don't display unnecessary information
20 \t-r | --reboot: reboot target on successful transfer
21 \t-V | --version: display version information
22
23 If no image (or url) is given, a flash dump is created.
24 A built-in http server is used when an image file is provided.
