Internet Reverse Access

A simple way to access your Raspberry Pi or Linux through the internet without messy steps!

Why is it simple?

• Works even if you are behind a NAT created by your internet provider
• You do not need a public IP (some providers make you pay for that)
• You do not need to setup any port forwarding on the router
• Uses serveo.net reverse access so its free and no registration is required
• Will let you access your webserver (port 80) and SSH connection (port 22) without any changes! You can configure others services and ports if you want.

How does it work?

You can read here all about how serveo.net works.
Basically what this repository contains is a init.d script that runs on boot, starts an autossh session and establishes the connection to serveo.net with the name you desire.

Requirements

You need to install autossh and git:

$ sudo apt update
$ sudo apt upgrade
$ sudo apt install autossh git

Installation

Installation is only 4 steps:

• Download
• Copy and modify
• Enable
• Profit!

First clone/download the repository:

$ git clone https://github.com/vascojdb/internet_reverse_access.git
$ cd internet_reverse_access

Then copy the script file to your init.d folder and change permitions to executable:

$ cp serveo /etc/init.d/serveo
$ chmod +x /etc/init.d/serveo

Now open the file with vim or nano and edit at your own will:

$ sudo nano /etc/init.d/serveo

You can edit the following lines, specially the SUBDOMAIN_NAME:

SUBDOMAIN_NAME="whateveryouwant"
WEB_LOCAL_PORT=80
WEB_INTERNET_PORT=80
SSH_LOCAL_PORT=22
SSH_INTERNET_PORT=22

After save the file and run the following to enable the script to be run on every boot:

$ sudo update-rc.d serveo defaults

Now test the script by running start/stop/restart

$ /etc/init.d/serveo start
Starting AutoSSh tunnel connection to serveo.net: http://whateveryouwant.serveo.net (Ports: WEB: 80, SSH: 22)

WEB access

Open your browser and access the following website:

http://whateveryouwant.serveo.net

SSH access

Open your favourite SSH terminal or browser (puTTY, WinSCP) and connect to the SUBDOMAIN_NAME (which is also the host name) on port 22 with your regular username.
You will need to configure the SSH to access the device using a proxy or tunnel, which should be set to serveo.net on port 22.
For more information check SSH forwarding

TCP access

You can also access any TCP port using this method, for this you need to take a look at Generic TCP forwarding and then modify the script file /etc/init.d/serveo according to your needs.

Custom domain

If you do not want to use the .serveo.net subdomain, you may set a domain of your own to look like .com for example. To do this please follow the section Custom Domain.

CONGRATULATIONS you will now be able to access your Raspberry Pi or Linux machine from the internet!
