After we have created our oracle compute virtual machine our next goal is to get our application installed on those virtual machines. Applications sitting on different virtual machines need to talk to each other internally too. For this internal connection we need to open ports between those machines.
For our application In this post we will open communication between the two instances on a specific port 50 and will enable a telnet service. After opening the ports on the VMs we will verify if we are able to telnet from one instance to the other on that specific port 50
