Valid options:
|
|
\t-h | --help: usage statement
|
|
\t-d | --dump: create a flash dump
|
|
\t-f | --file: use <filename> to store dump contents
|
|
\t-u | --user: provide username (default admin)
|
|
\t-p | --pass: provide password (default password1)
|
|
\t --port: set port for http (default 8080)
|
|
\t-q | --quiet: don't display unnecessary information
|

|
|
|
If no image (or url) is given, a flash dump is created.
