Script to quickly scan the S.M.A.R.T. health status of all your hard drive devices in Linux (at least all the ones from /dev/sda to /dev/sdzz). You need smartctl installed on your system for this script to work, and your hard drives need to have S.M.A.R.T. capabilities (they probably do).
#!/bin/bash
# install the smartctl package first! (apt-get install smartctl)
if sudo true

true

  • A USB drive is attached containing a debootstrapped Debian Jessie armel on an ext4 filesystem.
  • The original flash was completely erased.
  • A new version of u-boot provided by Evgeni was installed onto the flash.
  • The new u-boot version is capable of loading files from ext4 filesystems, the old one was not.
  • u-boot loads three files: /boot/uInitrd, /boot/uDtb, /boot/uImage

How to use 4G LTE modems like the MC7455 on both Debian/Ubuntu and OpenWRT using MBIM

The purpose of this document is to get you familiar with the concepts and command line tools involved with connecting to the internet using modern 4G LTE modems on both Debian/Ubuntu and OpenWRT.

This writeup is based on my experiences with the Sierra Wireless AirPrime MC7455 modem and a Calyx (Sprint) SIM card, but it should apply to most modern 4G LTE modems.

High level overview

These are the steps required:

  • Physically connect antennas

Meraki MS220-8P config without cloud bullshit
#!/bin/sh
# This script configures a meraki ms220-8p switch completely from scratch
# See https://leo.leung.xyz/wiki/Meraki_MS220-8P for rooting instructions
# You can keep config and config.local completely empty, but i'd recommend to add a configuration
# which isolates all ports from each other.
# Without that you might have switching loops on bootup (unlikely since STP keeps longer to initialize
# than it takes this script to take over, but it just feels cleaner).

OSDSYS image resource image information

The information in this documentation does not apply to the early Protokernel consoles which has a very different OSDSYS program.

The images stored in the ROM are in a compressed format, so decompress before use. The following is the implementation of the decompression routine: https://gist.github.com/uyjulian/14388e84b008a6433aa805f5d0436c87

The images stored in the ROM are raw image formats with no information attached, so the following table describes the extra information required to display the image.

| Filename | Size | Offset | Image format |
