Debian/Ubuntu font installation using command

by

Install a font manually by downloading the appropriate .ttf or otf files and placing them into /usr/local/share/fonts (system-wide), ~/.local/share/fonts (user-specific) or ~/.fonts (user-specific). These files should have the permission 644 (-rw-r–r–), otherwise they may not be usable.

Run fc-cache to update the font cache (add -v for verbose output). The above mentioned paths can be customized in the fontconfig configuration file at /etc/fonts/fonts.conf – you can also include subdirectories or links, which is useful if you have a directory of fonts on a separate hard drive (or partition or other location).

If you are installing bit map fonts you might need to enable this with dpkg-reconfigure:

# dpkg-reconfigure fontconfig-config

Install LAMP- Apache, PHP 7.4 with Apache Handler on Debian 12

by

Well, it’s not perfectly a LAMP stack as MySQL and PHPMYadmin are not covered here. But for someone who needs a backward compatible php edition to work on a modern/latest os built.

Step1: Add PHP repository

We’ll use a bash script to add the repository-

#!/bin/sh
# To add this repository please do:

if [ "$(whoami)" != "root" ]; then
SUDO=sudo
fi

${SUDO} apt-get update
${SUDO} apt-get -y install lsb-release ca-certificates curl
${SUDO} curl -sSLo /tmp/debsuryorg-archive-keyring.deb https://packages.sury.org/debsuryorg-archive-keyring.deb
${SUDO} dpkg -i /tmp/debsuryorg-archive-keyring.deb
${SUDO} sh -c 'echo "deb [signed-by=/usr/share/keyrings/deb.sury.org-php.gpg] https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'
${SUDO} apt-get update

Step-2: Install PHP Modules

Install a few dependencies required by this tutorial with the below-mentioned command:

sudo apt install software-properties-common ca-certificates lsb-release apt-transport-https

Install PHP 7.4:

sudo apt install php7.4

if you want to add multiple extensions then include them in braces, I am going to install “php-mbstring, php-mysql, php-xml, and php-curl” by running the below-mentioned command:

sudo apt install php7.4-mysql php7.4-mbstring php7.4-xml php7.4-curl

Nginx with Let’s Encrypt on Debian 10

by

Step 1 — Installing Certbot

The first step to using Let’s Encrypt to obtain an SSL certificate is to install the Certbot software on your server.

Installing the python3-certbot-nginx package from the Debian repositories will allow us to install and use Cerbot’s nginx plugin. Working with Python 3 and the python3-certbot-nginx package increases the longevity of our setup: Python 2 will be deprecated by January 2020, so our setup ensures compatibility with Python 3. Debian 10 currently supports both Python 2 and Python 3.

Before installing the python3-certbot-nginx package, update your package list:

sudo apt update

Next, install the dependencies for the python3-certbot-nginx package, which include the python3-acme, python3-certbot, python3-mock, python3-openssl, python3-pkg-resources, python3-pyparsing, and python3-zope.interface packages:

sudo apt install python3-acme python3-certbot python3-mock python3-openssl python3-pkg-resources python3-pyparsing python3-zope.interface

Finally, install the python3-certbot-nginx package:

sudo apt install python3-certbot-nginx

Certbot is now ready to use, but in order for it to configure SSL for Nginx, we need to verify some of Nginx’s configuration.

Softether with DNSMasq on Debian 11

What is SoftEther

A Free Cross-platform Multi-protocol VPN program, as an academic project from University of Tsukuba. It is a single server which support SSL-VPN (HTTPS) and 6 major VPN protocols (OpenVPN, IPsec, L2TP, MS-SSTP, L2TPv3 and EtherIP). I would like to also highlight the VPN over ICMP and VPN over DNS feature if you are inside a very strict network.

VPS Setup Guide

This post doesn’t use SecureNAT. 

On physical server, local bridge will perform better than SecureNAT
DO NOT enable both local bridge and SecureNAT at the same time. Packets will loop infinitly and make your server 100% CPU usage.
Requirement: VPS

Use a freshly installed Debian-11. My sample VM shape was:

  • Spec:RAM: 2048M
  • Disk Space: 20GB
  • CPU: 2vCPU
  • OS:Debian-11 bit (minimal)

Before installing SoftEther Server let us install some prerequisite.

apt-get update
apt-get install build-essential

Download Softether VPN for linux-

cd /opt
wget https://www.softether-download.com/files/softether/v4.43-9799-beta-2023.08.31-tree/Linux/SoftEther_VPN_Server/64bit_-_Intel_x64_or_AMD64/softether-vpnserver-v4.43-9799-beta-2023.08.31-linux-x64-64bit.tar.gz
tar zxf softether-vpnserver-v4.43-9799-beta-2023.08.31-linux-x64-64bit.tar.gz
cd vpnserver

Install Packages Dependencies

The first step is to install some packages dependencies such as gnupg2, nginx-full, sudo, apt-transport-https, curl, and java OpenJDK.

1. Update your Debian repository and install those packages on top using the following command.

sudo apt install apt-transport-https gnupg2 nginx-full sudo curl -y

2. Jitsi required Java OpenJDK version 1.8 or 1.11; the default Debian repository provides Java OpenJDK 1.11.

Now execute the following command to install Java OpenJDK packages.

sudo apt install default-jdk -y

After installation completes, verify the Java OpenJDK version using the following command.

java -version

You will see a similar output as below.

openjdk version "11.0.13" 2021-10-19
OpenJDK Runtime Environment (build 11.0.13+8-post-Debian-1deb11u1)
OpenJDK 64-Bit Server VM (build 11.0.13+8-post-Debian-1deb11u1, mixed mode, sharing)
