What is Steam Datagram Relay / Steam Networking?

Resources:

• https://partner.steamgames.com/doc/features/multiplayer/networking
• https://partner.steamgames.com/doc/features/multiplayer/steamdatagramrelay

Steam Networking is a bundle of APIs that do a lot of things and most notably support Steam Datagram Relay, which is provided by Valve to proxy connections to your server/SRCDS, to protect your server/SRCDS from DDOS, and provide P2P support.

Previously, if you could not port-forward your SRCDS server's ports, it would only work as a LAN server and other players wouldn't be able to join.

Only includes sub-text in filename if the picture includes subs.

Things this basically does:
	- Trim screenshot filenames to remove trailing '.', '_', and (c <= ' ').

Random Notes

• Right before a call, the stack must be aligned to 16-bytes.
  • (Right after a call, (rsp&8) == 8)
• In the called function: A frame pointer (RBP) is often used to realign the stack to 16-bytes.
  • push rbp + mov rsp, rbp

how many recursive CNAME records does your dns resolver resolve?
well there's an easy way and a hard way to figure out...

let's start with the hard way:
	- search golang dns server
	- end up with https://gist.github.com/walm/0d67b4fb2d5daf3edd4fad3e13b162cb and save main.go to a folder
	- search how to build a golang project and download imports because you don't remember
	- edit it to parse the deepest subdomain as an int and return a CNAME minus one of it
		- and also return a real A record if the int is 0
	- acquire a vps and scp your built binary to it
