  • Is it safe to have Nginx Proxy Manager point to my Octoprint docker instance - so I can reach it via (fake address) from outside my network?
    Your second method is not secure. Your domain might be obscure, but the IP address of the server is not, so it doesn't matter. Websites such as exist, if you fancy finding some OctoPrint instances exposed to the internet. If people don't add extra security their webcams are exposed to the world without even OctoPrint's login, so just don't do it. - Source: Reddit / 1 day ago
  • Am I safe?
    I back this recommendation. If for any reason you need to keep 443 open, I advise that you install an intrusion detection system such as Crowdsec in addition. Also, give a look at for your ip and check for the detected vulnerabilities. - Source: Reddit / 15 days ago

  • Port Sniffer made in Rust
    You can! Also detect if it's a public IP and use to display "offline" port-scans which is a cool idea. I played around with this for RustScan, something like "hey user, scanned this server 2 days ago. Do you want to see what ports they reported were open without scanning?". - Source: Reddit / about 1 month ago

  • Many random icmp6 requests in firewall log
    I remember setting up honeypot NTP servers and adding them to the public NTP pool ( They would log all source IP addresses and feed them into their automated scanners, which would give them a decent list of recently active machines, as most OSes automatically reach out to NTP servers to sync their clocks. - Source: Reddit / 3 months ago

  • How to Bypass Cloudflare: A Comprehensive Guide
    The actual "easiest" way (at least for me) to bypass Cloudflare is to find the actual IP of the web-server running behind it. Of course in a lot of cases it's not possible, for example when the web admin correctly limits the webserver to only respond to Cloudflare IP ranges, or if is used. Most useful services for that are and... - Source: Hacker News / 6 months ago
