I've heard tell that a good way to secure a Linux box that's doing this is to have it boot, set up the interfaces, set up iptables, and then do a quick /sbin/halt - if you fail to 'ifconfig down' the interfaces on the way down, the kernel will happily forward the packets while being immune to exploits
[ snip ] Hmmmm. A most interesting thought. Even if that doesn't work, one could modify /sbin/init to suit one's needs; several variants for embedded systems already exist. -- Eddy Brotsman & Dreger, Inc. - EverQuick Internet Division Phone: +1 (316) 794-8922 Wichita/(Inter)national Phone: +1 (785) 865-5885 Lawrence ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Date: Mon, 21 May 2001 11:23:58 +0000 (GMT) From: A Trap <blacklist () brics com> To: blacklist () brics com Subject: Please ignore this portion of my mail signature.
