Opening Ports on a Linode

In order to connect to a Linode, you will need to open ports. Port forwarding is a process of allowing specific traffic from a specific source port on your computer to a specific destination port on a remote server.

This guide will walk you through the process of opening ports on a Linode.

1. To open a port on your computer, you will first need to determine the protocol and port number for the service you wish to connect to. For example, if you wish to connect to a Linode using SSH, you will need to open the SSH port on your computer.

2. To determine the protocol and port number for a service, you can use a port scanner, such as nmap. To open the SSH port on your computer, you would use the following command:

  • nmap -p 22 –open

3. If you are unable to open a port on your computer, you may need to install a port forwarding application, such as UFW. To open the SSH port on your computer, you would use the following command:

PRO TIP: Opening a port on your Linode is a potentially dangerous operation that could leave your server vulnerable to attack. Make sure you understand the risks before proceeding.
  • ufw open ssh

4. Once you have determined the protocol and port number for the service you wish to connect to, you will need to open the port on the Linode. To open the SSH port on a Linode, you would use the following command:

  • Linode-ssh open ssh

5. Once you have opened the port on the Linode, you will need to configure your computer to connect to the Linode using the port you opened. To configure your computer to connect to the Linode using the SSH port, you would use the following command:

  • ssh -p 22 Linode-ssh

6. If you are unable to open the port on the Linode, or if you are connecting to the Linode using a different port, you may need to configure your computer to use a proxy. To configure your computer to use a proxy, you would use the following command:

  • ssh -p Linode-ssh.
