I am attempting to connect using two nodes on separate machines:
geth attach I enter this in machine 2-
geth attach http://10.132.0.2:8501 and get this -
Fatal: Failed to start the JavaScript console: api modules: Post http://10.132.0.2:8501: dial tcp 10.132.0.2:8501: getsockopt: connection refused
I am not that clear on how the nodes connect either using UDP or TCP; or if http is used.
How can I debug this? Should we be using enode anyway?
The node is running on machine 1.
