I've had a Pi running 24/7 for around 3 years - I use it to run network monitoring scripts, basic IDS for my website, uptime monitoring, etc.
When the Pi Zero came out I bought 4 of them and put them together into a 5-node grid computer, which to this day I use to run Einstein@Home.

- brutus1213 8y agoDid you use some opensource IDS software or just your own scripts? Stuff like nmap, snort? I've been wanting to do this for a while .. just tracking comms statistics from various devices so I can see what phones home.
- jamieweb 8y agoNo it's a bit more primitive than that. :) For basic IDS, it's a Python program I wrote a few years ago which does a recursive wget over my entire website, then generates SHA256 hashes of each page. Then it compares the hashes against the previous scan, and emails me if there are any changes. For very dynamic websites this doesn't work very well - luckily my site is almost 100% static so I can just whitelist the few allowed changes to prevent false-positive alerts. I also monitor my DNS and WHOIS for changes, so that if my domain or DNS is hijacked, then I hopefully will know about it more quickly.
