Apache2 Restrict direct IP access to website

Just added this into Apache2 config. E.g. /etc/apache2/sites-available/900-restrictDirectIP.conf and enable it afterwards.

<VirtualHost 192.168.0.1:80>
	ServerName 192.168.0.1
	Redirect 403 /
	ErrorDocument 403 "Sorry, direct IP access not allowed."
	DocumentRoot /var/www/html
	ErrorLog ${APACHE_LOG_DIR}/error_directIPAccess.log
	CustomLog ${APACHE_LOG_DIR}/access_directIPAccess.log combined

Cubietruck + Battery + Armbian - shutdown server if critical battery level reached. Just added it to /etc/cron.hourly

MOVED TO https://github.com/GAS85/cubietruck

I create a script that will try to send Warning Email and and shutdown the system as soon as it goes below 10%.

I put it in cron hourly and script should automatically check and do loop if battery discharging and below e.g. 80%.

E-Mail is needed because last time I did not know that my power supply died and I did not know why sever stopped. This version is also producing logs that could be checked after cubietruck fails. That helps for trouble shooting, e.g. to find out that power supply could not produce enough current to charge battery.

Log output example:

How to Enable HTTP/2 in Apache 2.4 on Ubuntu 16.04

Requirements

  • A self-managed VPS or dedicated server with Ubuntu 16.04 running Apache 2.4.xx.
  • For Ubuntu 18.04 please read here --> https://gist.github.com/GAS85/8dadbcb3c9a7ecbcb6705530c1252831
  • A registered domain name with working HTTPS (TLS/SSL). HTTP/2 only works alongside HTTPS because most browsers, including Firefox and Chrome, don’t support HTTP/2 in cleartext (non-TLS) mode.
