Question Possible rootkit, any readonly way to run check?

Hello all.
I think I may have had one of my systems compromised by a rootkit of some sort. I have ran chkroot several times and it has came up with nothing. Also my tripwire has taken a walk off the map. I can not get it to run. That was the first clue that I may have a problem. Since my system maybe compromised, there is no real way for me to tell using netstat, or top, or anything else for that matter. Is there a bootable linux distro that has any antirootkit software on it? I have heard of knoppix-std, but I looked on their site and they only have tools for forensics and firewalls. I didnt see any tools to check for rootkits. Also does anyone know of any rootkits that would try to trojan chkroot? I guess in essence it would be an anti- antirootkit kit.. lol! Oh and one more thing, are there any other rootkit checkers that may work better than chkroot, or maybe even fit on a bootable floppy? Any help or suggestions would be great! Thanks!

yeah.... root kit checkers are classified at forensic tools.

knoppix has chkrootkit.

Take a look at Knoppix-STD and F.I.R.E. as well.

It's very common to do something on a Linux box that maybe you don't remember doing and latter down the line it breaks your system or something of that nature. The first thing that comes to mine is OMG I just been owned! Sometimes that's rarely the case. So unless your for sure maybe try backtracing and see what you have done. Take a look in your .bash_history if you have it and see what commands root has entered from the terminal previously in regard to the issues your having, in your case anything pertaining to the configuration or alteration of tripwire.

Thanks for the help

Hey Thanks alot you guys. Im still working on it. I looked in my history and it looks okay. I cant really recall doing anything to my tripwire. I think I may have screwed it up when I was messing with my init scripts...Anyway knoppix-std and FIRE are great! Man I dont think Im gonna use anything else. I mean its a read-only file system, I dont have to worry about getting owned, all I have to do is reboot! LOL! Of course Im sure I will burn up my cdrom soon.
