samhain comes with
      default configuration files for several operating systems: 
      samhainrc.linux, 
      samhainrc.solaris, 
      samhainrc.freebsd, 
      samhainrc.aix5.2.0(and 
      yulerc for the server).
      The installation routine will choose the one matching closest
      your system, or fall back to 
      samhainrc.linux, if no
      good match could be found. However, all these configuration
      files are kept very general, and most probably you want to
      adjust settings like: 
      
which files/directories should be checked
which logging facilities should be used
The default location of the configuration file
      is 
      /etc/samhainrc(see 
      Section 10 ). To customize,
      type:
        sh$ vi /etc/samhainrc
      The default configuration file is heavily commented to help you. For a list of all runtime configuration directives, please have a look at Appendix C .
If you have any typos or other errors in your configuration file, samhain will log warning messages upon startup including the corresponding line number of the configuration file.
