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?
