I will focus more on the filter options part of IPTables, actually. > Do have a look on my slides. You may find the sketches useful. I just had a look. Your slides are very good and I remember them. What I plan to talk about is in totally different view. First of all - I am not going to mention NAT, neither mangling at all. I won't talk about masquerading but I'll focus on filtering, giving a wide introcution regarding the logic behind IPtables, I'll describe useful commands and give examples as well. At the 2nd part, I wish to describe some attacks scenarios and how to defend against them using IPtables. I'll also want to describe the concepts of building a firewall, using IPtables. I hope that there are people who like chains, in addition to "traditional code" :) > It seems to me that those who are with Haifux for a long time will not > be so interested, while the Staying-in-Linux audience can find it very > useful. Besides, that's your chance to get a slot before May. ;) Maybe. I'm not sure who wants to hear about it and who doesn't. It's actually a very relevant Linux subject which I believe that even the veteran users (who wish to know better what IPtables is) will be glad to hear about (Google proves my point ;). As for slotting it before May - I'm afraid that I won't have time to start working on it before March (exams, etc), so starting to work on it afterwards, while getting scehduled in the end of May, is great for me. Otherwise - I would have considered to give it earlier. > And what I see happening is that we get two tracks of lectures: One for > experts and one for newbies. I think this is a great thing. Maybe we > should make this official. Maybe. It sounds like a good idea. Anyway, regarding my lecture(s), if I split it to two, naturally there will be a basic lecture and a more advanced one. I'll be glad to give both as "regular" lectures and see later where and how it fits to a SiL series (of next year).
