Hello, I have a DSL internet connection using DHCP on my MDK 8.1 system. I am struggling through Oskar's tutorial but with a few changes have actually got it to work. Oskar does comment that he is not entirely satifisfied with his approach to the DHCP solution, and he suggests looking for other solutions to this problem. Actually, I have, but have not been able to find any other DHCP scripts except Oskar's. I do understand his reasoning for trying to grab the assigned IP instead of leaving a security hole using the standard script. Not knowing what would constitute a "better" solution, being a raw newbie on iptables, does anyone else have an alternative solution?
Subscribing to the "less is better" rational, I really do not know what the capabilities of iptables actually are with respect to solving common problems, which isn't really addressed in Oskar's tutorial, and only touched on lightly in Rusty Russels tutorial. A couple of things come to mind as a question. Can iptables drop emails that contain attachments? Can iptables drop emails that contain the word "attachment"? Can iptables catch an incoming HTM script that is actually an *exe file camoflaged as HTM? ( Virus) As a credit to Rusty, he does provide examples that address three other issues: Syn-flood protection Port scanning Ping of Death ( Thanks Rusty ) Thanks, Robert
