Hello all, I am just curious and want to know if there is any possibility of my Fedora Core 5 (and Core 6 in near future) being affected by rootkits. I recently came across a site which recommended to install chkrootkit on fresh Fedora installation. Here is the link --> http://www.oreillynet.com/onlamp/blog/2006/10/fedora_core_6_installation_hel.html Also there is an utility which can locate and remove (i suppose) rootkits called chkrootkit and can be found at --> http://www.chkrootkit.org/ Also I have installed Firestarter which disabled iptables on my system. Is it normal? Firestarter shows all the inbound (blocked) traffic, but, is it as good as default iptables? And also I want to know are these firewalls capable of blocking rootkit capabilities. I have installed many packages without using yum because of bandwidth problem, i just type yum install package-name and copy the list of packages needed and downloaded them from different sources at office and then installed the rpms. Is there any possibility of affecting my system using this method. If yes, how can i locate such problems? Also is there any other safer method installing rpms offline? I request all geeks in this forum to help me... This will help many others newbies like me too... So please help... Subrata Bera.
