This post explains how to install RKHunter  in Linux. Rootkit scanner is a scanning tool. This tool scans for rootkits, backdoors and local exploits by running tests like:

- MD5 hash compare
- Look for default files used by rootkits
- Wrong file permissions for binaries
- Look for suspected strings in LKM and KLD modules
- Look for hidden files
- Optional scan within plaintext and binary files

Rootkit Hunter is released as GPL licensed project and free for everyone to use. Can be downloaded from http://www.rootkit.nl



Installation:
Change to usr/local/src to download the package

#cd /usr/local/src
Download the package
#wget http://dfn.dl.sourceforge.net/sourceforge/rkhunter/rkhunter-1.3.6.tar.gz
Untar the source
#tar -zxvf rkhunter-1.3.6.tar.gz
#cd rkhunter-1.3.6
#./installer.sh --layout default --install

  1. I got some positive results but when I looked at the files they looked pretty normal to me.
