Date: Tue Aug 30 15:02:51 2005 From: Valdis.Kletnieks at vt.edu (Valdis.Kletnieks@...edu) Subject: RE: Example firewall script (iptables) On Tue, 30 Aug 2005 08:41:20 BST, =?iso-8859-1?Q?Bernardo_Mart=EDn?= said: > In my first email i requested about bad example firewall script, in later > mail i said that this script was to learn more so the scene isn't important > because i'm loking for bad script in any scene The scenario is *very* important - the firewall rules that I have on my laptop are demonstrably correct *for this usage*. However, they are also *incorrect* for other laptops, even others running Fedora Core 4 - of some 60 lines of rules, fully 3/4 of them are dealing with local oddities of our network and what I do (for instance, there's a ruleset that does nothing effective except make sure that iptables doesn't hit a '-j LOG' for a retransmitted FIN+ACK for a just-torn-down connection to our mail server that's no longer in the conntrack cache, so it doesn't show up in a feed to our DSHield server). And of course, it bears almost *no* relationship to what the firewall rules look like for our Oracle servers - running my firewall rules on the Oracle boxes would be a "bad script", as would running the Oracle rulesets on my laptop. -------------- next part -------------- A non-text attachment was scrubbed...
