How to Install Sish on Void Linux

Sish is a Linux-based reverse SSH connection service that allows you to access machines behind firewalls, NAT routers or without a public IP address. Here's how to install Sish on Void Linux.

Prerequisites

Before you begin, make sure your system is up-to-date:

sudo xbps-install -Suy

Installing Dependencies

Sish requires go and make to build from source. You can install them using xbps:

sudo xbps-install go make

Installing Sish

Once you have installed the required dependencies, you can proceed to install sish:

  1. Clone the sish repository:
git clone https://github.com/antoniomika/sish.git
  1. Change directory into the sish folder:
cd sish
  1. Compile and install sish:
make
sudo make install
  1. Verify the installation:
sish -h

If the installation was successful, the above command should output a help message.

Setting up Sish

Before you can use sish, you'll need to set it up. Here's how to do that:

  1. Create a configuration file for sish:
sudo nano /etc/sish.yaml
  1. Paste the following content into the file:
listen: 0.0.0.0:22
realip_header: "X-Real-IP"

This configuration tells sish to listen on all interfaces at port 22 (SSH) and to use the X-Real-IP header to determine the real IP address.

  1. Start the sish service:
sudo systemctl start sish
  1. Verify that sish is running:
sudo systemctl status sish

If everything is working, the output should say that the service is active (running).

Conclusion

Sish is now installed and configured on your system. You can now use it to access machines behind firewalls, NAT routers or without a public IP address.
