sish">Sish is a tool for creating reverse SSH tunnels. It is a simple yet powerful tool that allows users to access remote servers securely. In this tutorial, we will guide you through the installation process of Sish on OpenBSD.
Before we start with the installation process, you will need the following:
Sish is written in Go, so we need to install Go first. OpenBSD comes with pre-installed OpenBSD's own version of Go.
Run the following command to update the package repository and install the required packages:
sudo pkg_add go
This command will update the package repository and install the Go programming language along with its dependencies.
Now that we have Go installed, we can download and install Sish. Before installing, we need to set up the Go workspace.
Run the following commands to create the Go workspace:
mkdir ~/go
export GOPATH=~/go
export PATH=$PATH:$GOPATH/bin
These commands will create a directory named go in your home directory and set environment variables for the Go workspace.
Next, run the following command to download and install Sish:
go get -u github.com/antoniomika/sish
This command will download the Sish repository from GitHub and install it into the $GOPATH/bin directory.
After installing Sish, we need to configure it.
Create the configuration directory with the following command:
sudo mkdir /etc/sish/
Next, create a configuration file with your preferred text editor:
sudo vim /etc/sish/config.yml
In this file, specify the ports to be used for Sish:
listen:
- protocol: tcp
address: ":22"
permissions:
- username: "*"
password: "*"
ssh_host_key_files:
- "/etc/ssh/ssh_host_rsa_key"
In this example, Sish will listen on port 22 for incoming SSH connections. You can customize this port according to your needs.
Save and close the file.
Now that we have configured Sish, it is time to start the service.
Run the following command to start Sish:
sudo sish -config /etc/sish/config.yml
The service will start listening on the specified port.
Congratulations! You have now installed and configured Sish on OpenBSD. You can use it to create reverse SSH tunnels securely.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
