USING UBUNTU! Show me all code for each step! Be detailed please. * Apache running * All user html directories named pub. Therefore http://googee.nmu.edu/~fred gets mapped to /home/fred/pub. * Make a new user named WWW. The "/" gets mapped to /home/WWW/pub. Therefore http://googee.nmu.edu gets mapped to /home/WWW/pub/ * A basic index.html file in /home/WWW/pub * Setting such that there are no directory listings and no cgis runnable * The URL http://googee.nmu.edu/icons mapped to /home/WWW/Pictures/icons * Logs stored in /var/log/my_wb_logs in combined logfile format * A web analyzer (webalizer = 0.5, analog = 1.0) that shows activity stats accessable via the web. * The user 'someone' is unable to make web pages in his home directory tree, even if he's tricky.    No hand written and fast answer with explanation
