Script to deploy firmware to device using ethernet ipv6

  • #!/bin/sh

    while getopts "d:p:" opt;
    case "${opt}" in
    d) device=${OPTARG};;
    p) pass=${OPTARG};;

    if [ -z "$device" ]
    echo "Ethernet device not set, use parameter -d <device>"
    exit 1;

    address=$(ping6 -c 1 -i 4 -I $device ff02::1 | grep "64 bytes from " | awk '{print $4}' | cut -d"%" -f1 | awk -F':' '{print $0}')

    if [ -z "$address" ]
    echo "IP v6 address not set, use parameter -a <address>"
    exit 1;

    if [ -z "$pass" ]
    echo "Password not set, use parameter -p <password>"
    exit 1;

    ssh-keygen -f "~/.ssh/known_hosts" -R "$address%$device"

    echo "Sending Firmware to device...\n"
    sshpass -p$pass scp -6 -o StrictHostKeyChecking=no ~/source/bin/targets/ramips/mt76x8/openwrt-ramips-mt76x8-omega2p-squashfs-sysupgrade.bin root@[$address%$device]:/tmp

    @crispyoz Looks interesting, but can you give some context?

  • @Lazar-Demin

    I need to deploy my custom firmware build to my Omega2S+ based devices, but since a new board will not have a wireless connection I need to use the ethernet connection also built into my board. So there is no reliance upon ipv4 address, this script finds the connected ipv6 device, uses scp to transfer the firmware to the device, then executes sysupgrade on the device.

    Hi Thanks for you script. Can you tell me how to install sshpass? Please? THk

  • @Paolo-Moro sshpass is installed on your client machine, not on the Omega, so it depends on what OS you are running on your client machine. On Ubuntu you would use the command sudo apt install sshpass, on windows you can use putty as an alternative to sshpass

  • Thanks!!!!! I need to use an ONION OMEGA to setup the other ONION OMEGA!! šŸ™‚
    I need to install sshpass on Onion.


    What do you think about?

  • @Paolo-Moro Seems it will achieve the same thing but why not use sshpass?

    opkg install sshpass

    If it is not found then edit /etc/opkg/distfeeds.conf uncomment lines 2 and 5 then run opkg update then opkg install sshpass

  • If you want a version with more features for the same task, there's been omega2flash here for quite a while now šŸ˜‰

    It has some additional features such as:

    • prevents programming the same omega2(s+) twice
    • can handle (early production) omega2s having no ethernet address and fix that.
    • can set the uboot environment (useful place to have per-device info such as hardware version, without the need for different firmware images).
    • can flash extra files (initial data for the jffs overlay) along with the firmware image.
    • can be run in a loop (e.g. as a service) to program any omega2 hardware it finds on the specified ethernet interface. It does so sequentially, but as initiating the firmware update only takes a few seconds, whereas completing the update can take minutes, this amounts to pretty parallel flashing of multiple devices.
    • can run on standard macOS/Linux, but also runs on OpenWrt under ash shell - so a "flasher" device can be built based on any OpenWrt capable device (I have a PC-engines Alix for that).
    • uses expect tool (usually available on macos/linux) to enter ssh password or sshpass on OpenWrt.
