1. Coordinate with [email protected] (Leo Chen) on setting up "Harmony-Dev Role" for your AWS account.

2. Here are ip addresses of explorer services (mainnet vs. testnet) that we run on AWS Oregon region
AWS_EXPLORER=35.167.126.78
AWS_EXPLORER_LRTN=44.232.43.231

3. Find these instances and make sure to add your wifi public ip to the security group so that you can ssh into the machine from your ip.

4. SSH into the machine. ex) ssh -i ~/.ssh/keys/oregon-key-benchmark.pem [email protected]
