[opensuse] rkhunter related question
I'm getting the following warns from rkhuner. I know you can white list them, etc. My question is: how does the everyday user know if the command script found is a valid warning or a valid change that should be white listed? Thanks for any help. -- Russ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I think you forgot to post the warning you got. - -- Cheers, Carlos E.

It's not been replaced, it is a script. You can check the original file on the rpm from the dvd - for instance, on 11.1: /mnt/dvd/suse/i686/glibc-2.9-2.3.i686.rpm#rpm/CONTENTS.cpio#ucpio/usr/bin

same thing.

My guess is that rkhunter is seriously flawed if it can not recognize normal files on a suse install. Further more, it should know when some thing has been replaced or has been a certain way always. :-/ - -- Cheers, Carlos E.

rkhunter is not suse'fied, it does not appreciate the opensuse file locations. /sbin/chkconfig has not been "replaced by a script" but has been a script on SuSE/openSUSE for many distributions as has ldd and have the "ascii text" files below /dev/shm/sysconfig, etc., etc., etc. So, you may whitelist them, but then, if a rootkit did change one of the you would not know. But rootkit will not tell you either way on an openSUSE box :^(,. -- Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://counter.li.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Thanks, I'll add the check method to my list of tech tips I keep. Patrick mentioned that rootkit will not detect some of these problems. Is there another program you would recommend instead of rkhunter to to supplement it??
