Scripts & tools for building & configuring Cosmos ecosystem nodes

This toolkit is a collection of scripts, tips, & utilities that I've found useful during my time as a Cosmos ecosystem node operator.

Hopefully, you find some of these tools useful, too. :)

A simple script to automate the process of installing UFW and configuring some basic rules/ports for Tendermint-based chains:

• allow outgoing
• deny incoming
• allow ssh/tcp
• limit ssh/tcp
• allow 26656 (Cosmos peers)
• allow 26657 (RPC port)
• allow 9093 (we've configured this port for Prometheus, instead of port 9090)
• allow 16524/tcp (new SSH)
• limit 16524/tcp
• deny 22/tcp (default SSH)
• allow 1317 (LCD port)

The same script also includes the installation of Fail2Ban, a simple way to automatically ban IPs that are attempting to spam/bruteforce your server.

Pretty self explanatory. This script will run through the necessary setup steps required to isntall prometheus, as well as node_exporter_full, which are great for exporting node data directly to Grafana servers.

Note: this script is configured for port 9093 instead of the default port 9090.
