For some months now, I’ve been trying to set up an Mbin instance, since as it’s more manual than the other softwares I found, and I understand things better if I can see the logic behind them. I’d rather do that before going for automated processes where if something breaks, I don’t know how to handle. However, trying to figure things out as I go, it’s so much stuff that I figured out instead what I knew was very little.

As I was also interested in hosting other sites, this made me reevaluate things, and turns out several things I don’t know, like how to host two sites in a same machine, how to handle horizontal attacks, what some tools are used for, etc.

So going back to the title, what to study? Maybe some specific book? Private classes/courses? Online tutorials? Something else? Just no university suggestion, please - from experience, they are extremely shallow at best.

Thanks in advance!

    I’d start with some basic Linux networking and tools, if you don’t have them already.

    I don’t know if that’s the basics everyone knows these days, but… learn how TCP,UDP,ICMP,TLS relate, what a netmask is, what is ARP and MAC addresses. Fire up Wireshark and look around what is happening on your network. Learn some basic commands like ip -br -a and ss (or the older netstat) so you know how to figure out which program is listening where. Learn how to manually resolve a DNS name (dig or host). How tunnel a TCP connection or a webbrowser through ssh (port forwarding, SOCKS proxy). Learn enough of the HTTP protocol so you can manually enter a valid GET request over a simple TCP connection to port 80 with netcat or nc. Or use httpie or curl for the same purpose. You can’t host a lot with that knowledge, but it helps to figure out why things are not working.
