How to Install Sish on macOS

Sish is a tool that allows you to create a secure reverse proxy server that can redirect traffic to any destination. It can be useful in a variety of scenarios such as securing web servers, hiding your IP address, and more. In this tutorial, we'll cover the steps needed to install Sish on macOS.

Prerequisites

  • macOS (tested on Mojave)
  • Homebrew package manager installed (brew command)

Steps

  1. Open a terminal on your Mac and run the following command to install Sish using Homebrew:
brew install sish
  1. Verify the installation by running the following command:
sish --version

You should see the version of Sish that you just installed printed to the terminal.

  1. Start the Sish server by running the following command:
sudo sish server

Note that you must run this command with sudo privileges since Sish requires access to the system firewall configuration to function properly.

  1. You should see output that looks similar to the following:
[INFO]  entering pass-through mode, no targets defined
[INFO]  network listening on :2222

This means that the Sish server is ready and listening for incoming connections on port 2222.

  1. By default, Sish is configured to operate in "pass-through" mode, which means that it will simply forward traffic on to the destination without making any modifications. To create a target for Sish to redirect traffic to, you can use the sish target command.

For example, to create a target that will redirect traffic to example.com on port 80, you could run the following command:

sish target create --local_port 8080 --hostname example.com --remote_port 80

This command creates a new target that will listen on port 8080 on the local machine and redirect traffic to example.com on port 80.

  1. To start forwarding traffic to the newly created target, you can use the sish forward command.
sish forward --local_port 8080

This command will start forwarding traffic from port 8080 on the local machine to the target that you just created.

Congratulations, you have successfully installed Sish and created a target to redirect traffic to!
