IntroductionMany scenarios here, weblogic communicating with the database, for example.
I am going to make it even easier.
I will just create a second instance, as per the post #490.
Now I want to open communications between these 2 Oracle cloud instances.
I will open port 23 for tcp.
Step 1 is to create a new Security List
Step 2 is to add the Instance to the Security List
I do the same for VM1.
Here I create a new Security list - NiallC-VM-DB-Seclist
Step 3 is to create a Security Application, essentially opening port 23 for tcp
Step 4 is to create a Security Rule leveraging the above Security Application
and the 2 Security Lists
Testing via Telnet
I have installed telnet server on VM1
I have installed telnet client on VM, and, as you can see,
I can connect successfully.
