Proxmox VE Installation on Hetzner Server via Rescue System

Follow these steps to install Proxmox VE on a Hetzner server via the Rescue System. The Rescue System is a Linux-based environment that can be booted into to perform system recovery tasks. We'll be using it to install Proxmox VE.

In order to complete the process, it is indeed necessary to first boot into the Rescue System and then connect to it via SSH. This will allow you to run the commands for installing Proxmox VE. Here are the steps:

Starting the Rescue System

Log into the Hetzner Robot.
Under "Main Functions; Server" select the desired server and then open the tab "Rescue".

Helper script to map ports to other servers.

Use Case

had a database that was only accesible in the VPC on aws, so i created an dev intance and did a ssh tunnel to that dev instance with netcat mapping the port to the database

Sample Usage

Forward all request from local 5432 to remote host google.com port 80

./nc-proxy.sh 5432 google.com 80

	#!/bin/sh

	# script to automate the load and export to CSV of an oracle dump
	# This script assumes:
	# * you have the vagrant published key available locally in your .ssh directory
	# * You have the Oracle VirtualBox image running locally
	# ** ssh port-forwarding is configured for host port 2022 -> guess port 22.

	set -e

	#!/bin/bash
	#
	# git-mv-with-history -- move/rename file or folder, with history.
	#
	# Moving a file in git doesn't track history, so the purpose of this
	# utility is best explained from the kernel wiki:
	#
	# Git has a rename command git mv, but that is just for convenience.
	# The effect is indistinguishable from removing the file and adding another
	# with different name and the same content.
