![]() By using the ssh command, you can easily create a secure tunnel to a remote server and route your internet traffic through it. Setting up an SSH tunnel on Linux can be a useful way to protect your online privacy and security. To avoid this, you can use a tool like autossh, which automatically reconnects the SSH tunnel if the connection is lost. If the connection is interrupted for any reason, the tunnel will be closed and you’ll need to set it up again. ![]() Network traffic from the local machine is routed from an arbitrary specified port. Remember that SSH tunnels require an active connection to the remote server in order to remain open. An SSH tunnel is a secure connection between an SSH client and an SSH server. īy using SSH tunneling, you can securely access resources on remote servers and forward ports between machines without exposing them to the public internet. For creating a TUN tunnel, will leave here a practical script, from Ip Tunnel Over Ssh With Tun the script assumes you are running as root. You can then access the web server running on your local machine by connecting to. Using OpenSSH in Linux, tunnels can be created over SSH using either TUN or TAP interfaces, as long as proper routing is setup and ip forwarding where appropriate. This command forwards port 8080 on the remote server to port 80 on your local machine. On your local machine, run the following command: ssh -R 8080:localhost:80 For example, if you have a local machine running a web server that you want to allow access to from a remote server, you can use reverse SSH tunneling to create a secure connection between the two machines. Reverse SSH tunneling is used to allow a remote server to connect to a local machine. You can then connect to the database server running on the remote server by connecting to localhost:3306 on your local machine. This command forwards port 3306 on the remote server to port 3306 on your local machine. Here’s an example: ssh -R 3306:localhost:3306 For example, if you have a database server running on a remote server that you want to access from your local machine, you can use remote SSH tunneling to forward the database server’s port to your local machine. ![]() Remote SSH tunneling is used to forward a remote port to a local machine. This command sets up an SSH tunnel that maps the local port 8080 to the remote server’s port 80, allowing you to access the remote server’s web server on your local machine by navigating to “ in your web browser. By default, SSH uses port 22, but you can specify a different port number if necessary.įor example, if you wanted to set up an SSH tunnel on port 8080 to access a web server on a remote server with the IP address 192.168.1.100, you would use the following command: ssh -L 8080:localhost:80 -p 22 You can specify the username to use for the connection before the hostname, like this: -p : The port number to use for the SSH connection.
