Manual Upgrade

Packet Squirrel firmware may be updated via USB as described in the updating firmware articlearrow-up-right. That said, it is also possible to manually upgrade the firmware by following this process:

  1. Download the latest UPDATE file from https://downloads.hak5.org/squirrelarrow-up-right and verify its checksum.

  2. Power on the Packet Squirrel in Arming Mode

  3. Manually SCP the file to the Packet Squirrel's /tmp directory (e.g. scp upgrade-3.1.bin [email protected]:/tmp/)

  4. SSH into the Packet Squirrel (e.g. ssh [email protected])

  5. From the Packet Squirrel's bash prompt, issue the sysupgrade command relevant to your firmware update file (e.g. sysupgrade -n /tmp/upgrade-3.1.bin)

  6. Wait 5-10 minutes as the Packet Squirrel flashes the firmware and reboots.

DO NOT unplug the device during the process as doing so will render the device inoperable.
