  1. To SSH to the VM, Open putty paste the IP address and click on Open.

  2. /img/aws/ethereum-fullnode/putty-01.png

  3. login as ubuntu and provide the password for 'ubuntu' user

  5. Ethereum Full Node directories:
  6. Ethereum home directory location is /home/ubuntu/ethereum


    Data directory location is /home/ubuntu/ethereum/datadir


  7. Monitoring and managing node sync process :
  8. The VM automatically starts the sync process on startup. To verify if the sync is in progress, run below commands

    ps -ef|grep geth

    If sync is in progress , you will see the below highlighted process running


    You can also verify the sync process by monitoring the sync log as shown below

    tail -f /var/log/cloud-init-output.log


    To stop the sync process, simply run below command :

    sudo killall -HUP geth


    To restart the sync process, run below command .
    Note: Make sure below command is executed from terminal inside Remote desktop GUI to avoid process termination

    sudo nohup geth --rpc --rpcaddr "" --rpcport "8545" --rpccorsdomain "*" --config /home/ubuntu/ethereum/eth_config.toml >> /var/log/cloud-init-output.log 2>&1 &


  9. Tracking sync progress
  10. You can track the sync progress by attaching to the running geth console and running the monitoring script as shown below . Note that if the progress is shown 99% then the node is mostly synced:

    sudo geth attach --datadir /home/ubuntu/ethereum/datadir/


    this will connect to the console, then run



  11. Accessing Metamask Ethereum wallet
  12. The VM comes with Metamask the most popular Ethereum wallet , preinstalled in Firefox browser.
    Connect to the VM via Remote desktop , open the Firefox Browser and you will see metamask plugin in the browser


    • If you want to connect Metamask on localhost, Please add port 8545 to the Security Group of your VM. Follow below steps to open port 8545:

    • On your VM's detail page, click on networking tab:
    • /img/azure/ethereum-fullnode/networking-8545.png

    • It will open networking details page. Click on Add inbound port rule.
