Open Firewall Rules On Servers Cloud Playground

What are Cloud Playground Servers?

Cloud Playground Servers feature allows you to launch up to 9, and different sizes, virtual machines. These servers are used throughout the Linux Academy courses to help you learn hands-on. The amount of time it takes to get started, risk of misconfiguration or missing packages on your local machine go down to zero so you can easily get started training. 

What Can I do with Cloud Playground servers?

Cloud Playground servers come with IPV4 and IPV6 support. You can attach multiple volumes to play with LVM/Raid, each server has a public hostname, public ip address and internal IP address. You can easily spin up different Linux distributions as well as Windows versions in the Cloud playground at Linux Academy. This is your own personal Cloud based lab all included in the price of your membership.

What ports are open on Cloud Playground servers?

Note: All ports between your own servers launched in Linux Academy Cloud Playground are open by default. However, you must use the internal IP address when connecting to those servers. We only allow certain external ports to be open.

What ports are open on the servers?

The servers by default do not have pre-installed firewall software. This allows you to have the greatest flexibility when controlling your own personal lab on Cloud Playground. However, on the public network layer we do only allow certain ports to be open. Think of it this way, your servers are houses in a gated community. The gated community has a guard gate that only lets in certain cars. This is how our network works. If you are using the public IP address only certain ports are open to external traffic. However, all ports are open to internal traffic to your own servers if you are using the internal IP addresses.

All ports are open and available when using the private network between Playground servers, however most public ports are currently blocked for security reasons. The following are the current ports that are white listed and available to use across the public internet on the Linux Academy Cloud Playground.
