Compile

I have used dart sdk 2.17.1 (stable)

Clone the repository and cd into it

cd packages
git clone https://github.com/zenon-network/znn_sdk_dart
cd znn_sdk_dart
dart pub get
cd ../..
dart pub get
dart compile exe sentrify.dart -o sentrify

Transfer it to your pillar

scp sentrify root@ip:/path/

Usage

This is a tutorial on how to sentrify your node, meaning that it will only communicate with the sentries

At least 2 sentries are recommended per node

Only works for ipv4 for now

Firewall rules are persistent to reboot

Get unzip, znn bundle and sentrify

apt-get update
apt-get install unzip
mkdir alphanet && cd alphanet
wget https://github.com/zenon-network/znn-bundle/releases/download/v0.0.1-alphanet/znn-alphanet-bundle-linux-amd64.zip
unzip znn-alphanet-bundle-linux-amd64.zip
wget https://github.com/MoonBaZe/sentrify/releases/download/release/sentrify
chmod +x sentrify

Add swap memory

Add 16 GB of swap so the node can process any block and won't get stuck for too long

fallocate -l 16G /swapMem && chmod 600 /swapMem && mkswap /swapMem && swapon /swapMem && echo '/swapMem none swap sw 0 0' | tee -a /etc/fstab

Transfer producer keystore and config.json to the pillar (only if using a new vps)

mkdir -p /root/.znn/wallet - on the new pillar vps

scp /root/.znn/config.json root@ip:/root/.znn - on the old pillar vps, change ip with the new pillar vps ip scp /root/.znn/wallet/producer root@ip:/root/.znn/wallet/ on the old pillar vps, change ip with the new pillar vps ip

Use controller to download znnd and create service

./znn-controller and choose option 2 (deploy) - to download znnd and create the service

choose y as you want to continue with the configuration

./znn-controller and choose option 5 (stopService) - stop it for now

Bootstrap (optional)

./sentrify and choose option 1 - will ask for bootstrap url, will download the blocks and genesis and put them in the default directory

bootstrap url: https://github.com/MoonBaZe/sentrify/releases/download/release/bootstrap.zip

Otherwise, you can download the genesis and wait for the node to sync when we start the service

cd /root/.znn
wget -O genesis.json https://ipfs.io/ipfs/QmVFyGWNt3Ph2mn9MoxZyTgjuMGSs2cDdqXP3B8Ri5AYY5?filename=genesis.json

Remove peers

./sentrify and choose option 3 - this will remove all peers from config.json if you have any

Add sentries

./sentrify and choose option 2 - will ask for sentry ip and then ws port, so it can take it's public key and add it repeat for all your sentries

Sentrify

./sentrify and choose option 4 - will add firewall rules so that your node only accepts ssh, dns (so controller works) and your sentries

Enable firewall

ufw enable - then y - don't worry, will not interrupt your ssh

Start node

./znn-controller and choose option 4 (startService)

Tips

Every time you add a new sentry, you should run sentrify (option 4) and then enable ufw

Peers url ONLY for sentries: https://ipfs.io/ipfs/QmeAUQkpoEMNRQ9SFcBV2kmRTXT3WLKAoMxvAtX2ErZubJ?filename=peers.json
