I used two virtual machines to do this experiment, one as the host and one as the client. I have made the following changes: I installed geth on both vms, and used ssh to connect two vms. I modified env.sh according to my own path and modified hosts and clients according to the ip address.All the dinhtta in the script is also changed to mine What else do I need to do?
