 --=| QUICK START GUIDE TO KNOCKER |=-------------------------------
     ------------------------------

   -[ How to build and install knocker ]-
      --------------------------------

   1. Unpack the package: tar -zxvf knocker-X.X.X.tar.gz
   2. cd knocker-X.X.X
   3. type: ./configure
   4. make
   5. (Become root if you want to install knocker system wide) type:
      make install
   
   -[ Quick start ]- 
      --------------------------------------------------------------

   1. If you have installed knocker with make install you should be
      able to execute it just by typing: knocker
      otherwise cd into the src directory under the unpacked source
      tree and type: ./knocker 
      or better: knocker --help

   2. Now to perform a simple port scan to a host (let's use your
      host as target...) type: knocker --host localhost
   
   3. Let's say you have to perform a long scan and you want the
      program to run in background so you can continue your work... 
      just type: 
     
knocker --host thehost --start-port 1 --end-port 4000 --quiet &

  or in a shorter form:

knocker -H thehost -SP 1 -EP 4000 -q &

      you won't see any output this way... just do: 
      cat ./knocker_scan.log 
      to see the scan results.

 Or if you want to log to a particular file:
      
knocker -H thehost -l logfile.txt

If you want to scan only one port:

knocker -H thehost --port 21
