Hi char1226, can you please describe your environment in more detail?. It seems that it is a name resolution problem. What do you mean by "two terminals?" I understand that you followed the full guide and therefore you created a new network in the container engine environment. You have to be sure that DNS is enabled in the container network you created. If you are not using containers, you need to be sure that name resolution is enabled (you can configure the /etc/host file with the proper entries, for example), so that simulaqron can resolve the names defined in the network.json file for the net "newnet". Please review the example of the file network.json in the post, as you can see it is using as node name Alice.dns.podman and Bob.dns.podman. These names are resolved by the embedded DNS service in the container engine example I used for the post. I hope this can help. Thank you for your comment.
