Notes & write-ups
Thinking out loud about what I broke, what I learned, and what I'd do differently.
- Reading auth logs by hand before reaching for a tool A small Python script that counts failed SSH logins per IP, and what it taught me about log triage.
- Writing a subnet scanner to see how host discovery works A standard library Python tool that pings a subnet for live hosts and checks common ports, and what it showed me about the network stack.
- My first socket program: a LAN chat room A console chat app in Python with a server and multiple clients, and the networking basics I picked up building it.
