This repository contains a collection of useful bash scripts that can be used to configure various operating systems and developer machines. The scripts have been tested on the following systems: Ubuntu, Armbian, OpenWrt, macOS. Please note that some scripts may require administrative privileges to run.

Flash Armbian and setup Avahi Daemon for local network discovery

The most anoying thing for me is to discover Armbian computer IP for inital ssh to config the OS. Usually I go to the router webconsole to see DHCP leases and this is very anoying. I created

armbian-flash.sh ~/Downloads/armbin.img.xz /dev/sdb

script to flash the image and then install Avahi daemon, so you will discover your Arm host in the network using mDNS, for instance using bananapi.local mDNS name.

Chroot into Arm-based Linux

You can simply insert a RaspberryPi, BananaPi or OrangePi flash into your Linux machine and chroot into the embedded Linux rootfs using bin/chroot-arm.

bin/chroot-arm /media/$USER/sdcard

Configure VPN servers

This script configures a Wireguard server and generate configurations for the clients

curl "https://raw.githubusercontent.com/dzianisv/utils/master/bin/linux-configure-wireguard.sh" | N=10 bash -x

Or configure PPTP server on the Linux host:

```sh
curl "https://raw.githubusercontent.com/dzianisv/utils/master/bin/linux-configure-pptp-server.sh" | bash -x
