I'm trying to build a simple Anti-DDoS for a game using IPTables. I don't know from where to start and just my question now is:

Assume that i'am using Ubuntu, I need to make a script or program (i don't really know what to call it) that in some cases after some checks for the coming packets it will add a rule to IPTables automatically for sometime and it will be removed after time also that i define. In other words like Auto-Filter i need to build.

For this which programming language i should learn to start my project?

Please give me examples if you can. Thanks.

  • Time ago I've wrote this answer, that could give you some ideas. Unfortunately I think your question is too broad. You should be more specific. – pa4080 Sep 05 '17 at 19:19
  • Simply here is an example, Always check coming packets and if found a packet contain some hex-string then place a filter to drop this packets and this iptable rule will stay for sometime like 1 day and after it the rule removed. – gamer-cs Sep 05 '17 at 20:25
  • You mean something like How to block DDoS attacks on server with Steam :) – pa4080 Sep 06 '17 at 06:00
  • This man will put a normal rules... I don't need it like that i mean how i can make checks for every packet input to my server and for some cases if the packet contain something i already defined so a rule is added for sometime and it will be removed after this time elapsed. Hope you get me. This what i try to do i don't know with which program language i should start. – gamer-cs Sep 06 '17 at 09:30
