USB Autorun
This feature can be used to automatically launch a shell script or perform a software/con g
update as soon as an USB storage stick has been plugged in. For authentication, a le called
autorun.key must exist in the root directory of a FAT16/32 formatted stick. It can be down-
loaded from that page and holds the SHA256 hash key of the admin password. The le can
hold multiple hashes which will be processed line-by-line during authentication which can
be used for setting up more systems with different admin passwords.
For new devices with an empty password the hash key
e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
can be used.
The hash keys can be generated by running the command echo -n "<admin-password>" |
sha256sum on a Linux system or an Internet hash key generator (search for "sha-256 hash
calculator").
Once authentication has succeeded, the system scans for other les in the root directory
which can perform the following actions:
1. For running a script: autorun.sh
2. For a con guration update: cfg-<SERIALNO>.zip (e.g. cfg-00112B000815.zip), or if
not available cfg.zip
3. For a software update: sw-update.img
