Check logs

sudo journalctl -u epixd -fo cat

Check Sync

curl -sL https://raw.githubusercontent.com/astrostake/scripts/refs/heads/main/cosmos_sync_monitor.sh | bash -s -- --directory $HOME/.epixd --public-rpc https://epix-rpc.linknode.org --interval 5

🛡️ Security

To apply a quick security baseline, you can configure your firewall like this:

sudo ufw allow ${EPIX_PORT}656/tcp comment 'EPIX Node p2p Port'
