...remain unsure, it is best to reinstall the system to be sure that a fresh and newly updated (yeah update it when installed :)) system is not compromised at that time.. loads of work, but it gives you some relief to know that it's clean.

Hi, I am using IPFW on FreeBSD 4.11 I am facing two problems: - SSH sessions timeout after a while - When I run "/sbin/ipfw -q -f flush" in the rules script all connection get reset (and I am thrown out of the box). Is this standard functioning of ipfw or do I need to change any configuration? Thanks, Siddhartha

My guess, you are affected :) cheers -- Kind regards, Remko Lodder Elvandar.org/DSINet.org www.mostly-harmless.nl Dutch community for helping newcomers on the hackerscene -----Oorspronkelijk bericht----- Van: freebsd-security-bounces@lists.elvandar.org [mailto:freebsd-security-bounces@lists.elvandar.org]Namens Daniel Spielman Verzonden: dinsdag 2 maart 2004 21:06 Aan: freebsd-securi...
