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 ${DORA_PORT}656/tcp
sudo ufw enable
Delete node
