SSHuttle in use

Make use of sshuttle to tunnel system in robust and flexible way.

Auto setup (using Makefile)

You should have installed make package. You can run only make to setup all components or you can run make with custom actions.

make

Manual Setup

First, you should install sshuttle according to its manual. Mostly, the following command is enough:

sudo apt install sshuttle

Then, you should install a systemd service template and a bash script to be able to make sshuttle in control:

# clone repo
git clone https://github.com/armanexplorer/sshuttle.git

# make the service template ready
sudo cp sshuttle/sshuttle@.service /etc/systemd/system/
sudo systemctl daemon-reload

# make the control script ready
sudo cp sshuttle/vpn.sh /usr/local/bin/vpn
sudo chmod u+x /usr/local/bin/vpn

Run

To start vpn:

sudo vpn <user>@<server>

You can also use /root/.ssh/config file to define alias names instead of <user>@<server>.

Note: The controller script (vpn) only allows for one active VPN. You can change it with disabling the if condition in the vpn.sh before installing it.

To stop the all VPNs activated using this tool, simply run:

sudo vpn off

Troubleshoot

You can check logs using sudo journalctl -xeu "sshuttle@<user>@<server>.service".

In case of Host key authentication failed error in the logs, you can add --ssh-cmd "ssh -i /home/user/.ssh/custom_id" flag to the sshuttle@.service file and run sudo systemctl daemon-reload. Using this, you will specify the full path to your custom SSH key, instead of using the default one.
