  1. Guys, I'm now running my nodes with the scripts os SebastianJ. In htop (install with apt install htop ) I can kill one of the node's processes with F9 (SIGTERM) and then after a second I see the node process starting again. It's awesome what systemd does, I think. 🙂 What you do for, say, 3 nodes is: 1) You zip your pem files for each node ( keys-8080.zip for your 1st node, keys-8081.zip for your 2nd node, keys-8082.zip for your 3rd node) 2) You create 3 folders to hold your zipped pem files: mkdir -p ~/elrond/keys/8080 mkdir -p ~/elrond/keys/8081 mkdir -p ~/elrond/keys/8082 3) You copy each zip file to the right folder, one of the three folders you created in step 2 4) You stop your nodes with: tmux kill-server 5) You run Sebastian's scripts with bash <(curl -s -S -L https://raw.githubusercontent.com/SebastianJ/elrond-tools/master/setup/setup.sh) --nodes 3 --display-name YourName --start --systemd This will create 3 running nodes with node names: YourName-1, YourName-2 and YourName-3. --------------------------------------- You can see all your nodes' statuses with: systemctl status elrond@808*.service You can restart (stop and restart) all your nodes with: systemctl restart elrond@808*.service You can stop all your nodes with: systemctl stop elrond@808*.service You can start all your nodes with: systemctl start elrond@808*.service If you just want to do these things for just 1 node, don't use 808*, but for instance 8082. Instructions and code can be found here: https://github.com/SebastianJ/elrond-tools/tree/master/setup
  2. Hi guys, I've written a Medium post about how to secure your VPS (Ubuntu) by: - using SSH keys with Ed25519 encryption - setting a non-default SSH port - setting the firewall so that only outside access through a single SSH port is allowed - disabling root access from the outside - switching to user root with a simple `su -` command, without a password Check it out at: https://medium.com/@haklander/how-to-secure-your-ubuntu-vps-for-running-an-elrond-node-a5e0493646b6
  3. Be careful if there is NOT a new testnet version, but a patch for instance. Then you want to keep your /db folder. So stop the node, copy your /db folder and your /config/*.pem files to a safe location (always keep a copy of initialNodesSk.pem and initialBalancesSk.pem in a safe place) and then do the update. After the update, copy the /db folder and your /config/*.pem files back to your updated node folder structure.
  4. Added an option `-w` to show all offline validator nodes. W for Warning. 😉 bash monitor_nodes.sh -w
  5. Hi everyone, I wrote a bash script for Ubuntu, that you can download and use like below. It should be run on the machine where you run your node. Default REST-api port that's used is 8080, if you set another port, you should modify the script (look for 8080 and change it to the desired port). Have fun!

  6. Wow, such transparency! Good!

  11. Hi guys, made a video for easy node installation in 5 minutes for Ubuntu users. It's also in my Medium post. Good luck!
  12. I just finished writing a Medium post on how to run and maintain one or multiple nodes in Ubuntu 18.04. I hope you like it and please send me feedback for improvements! https://medium.com/@haklander/run-and-maintain-one-or-multiple-elrond-nodes-in-ubuntu-18-04-5f5c9658e580
  13. For installing/upgrading one or multiple nodes in Ubuntu 18.04, an alternative set of scripts can be found here. It should be self-explanatory (scroll down for instructions), but if there are questions, I'd be happy to answer them! https://github.com/ahakla/elrond-nodes This may be integrated in the official ElrondNetwork 'elrond-go-scripts' repository, but until then you can just use the link above.
  14. Hi all, A few interesting general resources about Elrond: General https://info.binance.com/en/research/ERD-2019-06-20-d893c3.html https://messari.io/asset/elrond#profile “Elrond Validator Economics Proposal” by Beniamin Mincu https://link.medium.com/kFq41x9On0
  15. Hi Force! Yes, the Elrond code is completely open source, this was decided in June, see “After Exceeding 10k TPS in Testnet, Elrond Is Going Open Source” by Beniamin Mincu https://link.medium.com/XQdqfSkMn0. The complete Elrond source code can be found here: https://github.com/elrondnetwork. Best regards, Alwin
