Check your Raspberry pi power supply and USB cable
#!/bin/bash
# Before running this script, make sure you have sysbench installed:
# sudo apt-get install sysbench
#
# This script helps you check if your Raspberry pi is correctly powered.
# You can read more about Raspberry pi powering issues here: https://ownyourbits.com/2019/02/02/whats-wrong-with-the-raspberry-pi/
# If you're pi is correctly powered (stable power supply and quality cable), after running the script, you should get something like:

GCC compiler optimization for ARM-based systems

GCC compiler optimization for ARM-based systems

2017-03-03 fm4dd

The gcc compiler can optimize code by taking advantage of CPU specific features. Especially for ARM CPU's, this can have impact on application performance. ARM CPU's, even under the same architecture, could be implemented with different versions of floating point units (FPU). Utilizing full FPU potential improves performance of heavier operating systems such as full Linux distributions.

-mcpu, -march: Defining the CPU type and architecture

These flags can both be used to set the CPU type. Setting one or the other is sufficient.

examples of SNAT, DNAT with iptables for Advantech, Conel routers, with comments (probably will work on other routers where iptables can be manipulated, care needs to be taken on applying these commands after reboot).

Some examples of SNAT, DNAT with iptables with comments

mainly used in start-up script

How to test 'safely'

When we play with iptables aka firewall we might end up in situation, where we execute rule, which has unforseen impact - lock yourself out. Recovering from this situation is necessity.

How to:

  • Enable reboot via SMS.
  • Test all commands in shell first before putting them into Start-up script. This way the command will be wiped out, when unit is rebooted.
