Fix the fc3c.

1. Start the sisnew.sh
2. scp -r <login>@sanluis:public_html/hw4/lvs .
3. shutdown -h now
4. Run makecow.sh to create three copy-on-write (cow) file system for three virtual
   machines.
5. Create three terminal windows. cd sis. run ant.sh, buck.sh, cow.sh on each window.
6. Login to each virtual machine. cd directory with the name of the machine.
7. run setup.sh This will set the hostname, configure the interface with IP, 
   set default gateway, set /etc/hosts file, set default web page, and start the httpd.

Note that when starts the vi of our virtual machine, it warns that "skip 6 old sessions".
We can clean it up by remove the old session files in /var/tmp

To change the display mode from html to nornal (plain text) mode. in vi(elvis) type :no
(for normal) I guest.

In /usr/share/elvis-2.2_0/elvis.arf we can set display mode for files with .html
to be normal instead of html (line 28).
