Monitoring

If you want to have set up a monitoring and alert system use our cosmos nodes monitoring guide with tenderduty

Security

To protect you keys please don`t share your privkey, mnemonic and follow basic security rules

Set up ssh keys for authentication

You can use this guide to configure ssh authentication and disable password authentication on your server

Firewall security

Set the default to allow outgoing connections, deny all incoming, allow ssh and node p2p port

sudo ufw default allow outgoing 
sudo ufw default deny incoming 
sudo ufw allow ssh/tcp 
sudo ufw allow ${ARTELA_PORT}656/tcp
sudo ufw enable

Delete node

sudo systemctl stop artelad
sudo systemctl disable artelad
sudo rm -rf /etc/systemd/system/artelad.service
sudo rm $(which artelad)
sudo rm -rf $HOME/.artelad
sed -i "/ARTELA_/d" $HOME/.bash_profile
