Re: Can I block _only_ privileged access with ipchains?

Consider this the pre-release announcement; I've still got a bit of clean-up work to do on it, but it's basically finished. If you're running Linux 2.0, check the ipfwadm(8) man page; my docs might still be of use. -- Carey Evans http://home.clear.net.nz/pages/c.evans/ The risk of U.S. national security resting in the hands of adults who play with children's toys during office hours is left as an exercise to the reader. - Bruce Martin in RISKS
Can I block _only_ privileged access with ipchains?
Sorry, I know this isn't exactly debian specific... I want my firewall to allow access from unprivileged ports to unprivileged ports. So, if I connect to an ftp site on a port above 1023 and my client is using a port above 1023, the packets are allowed to cross. Possible? I can find anything about it in the docs. Any other comments? I know that this would allow a malicious user on my network to do insecure things, but I trust myself, my wife, and my two month old baby ;-) Thanks, Dale -- +- pgp key available --+ | Dale E.
