[Okay, let's try this again. I meant this to go to linux-kernel, but I was a monkey and only sent it to David S. Miller who promptly responded with some great ideas (thanks again David!) but I wanted to get some other thoughts from other folks out there. Maybe someone had the same problem I did...]

Um, is there any documentation of this? I need to learn more about SYN and RST cookies and such. I know their purpose, I know they take two different approaches, and I know RST cookies use more memory. However, I run MUDs on my Linux box (RH 5.0 - 2.0.33) and when I ran SYN cookies, people were having problems with the game hanging up on them. This was reported to the mailing list for that type of MUD (it's actually MUX), and -only- people using Linux were having problems with that. The author of MUX decided to blame it on Linux and move on. After switching to RST cookies, I don't think I've had anyone get hung up on. Can anyone enlighten me on this?
