 #### Instructions:
 
-1. To load this project you need to run QtCreator with administrator (root) privileges. 
-`sudo qtcreator Documents/eip/classes-simplesniffer/SimpleSniffer.pro`
 
-2. Load the project `SimpleSniffer` into `QtCreator`. There are two ways to do this:
+1. Load the project `SimpleSniffer` into `QtCreator`. There are two ways to do this:
 
-    * Using the virtual machine: Double click the file `SimpleSniffer.pro` located in the folder `/home/eip/labs/classes-simplesniffer` of your virtual machine.
-    * Downloading the project’s folder from `Bitbucket`: Use a terminal and write the command `git clone http:/bitbucket.org/eip-uprrp/classes-simplesniffer` to download the folder `classes-simplesniffer` from `Bitbucket`. Double click the file `SimpleSniffer.pro` located in the folder that you downloaded to your computer.

 ### Exercise 2 - Complete the class ethernet_packet
 
 1. Study the file `ethernet_hdr.h`. This file contains the definition of the data structure that represents an Ethernet header.:
 
-         #define ETHER_ADDR_LEN 6
-
-         struct sniff_ethernet {
+        #define ETHER_ADDR_LEN 6
+        
+        struct sniff_ethernet {
             u_char  ether_dhost[ETHER_ADDR_LEN];    /* destination host address */
             u_char  ether_shost[ETHER_ADDR_LEN];    /* source host address */
             u_short ether_type;                     /* IP? ARP? RARP? etc */
-         };
-     
+        };
 
-     The Ethernet header above is used to decode the ethernet part of the raw data in each packet.  It is composed of the source MAC address (ether_shost, 6 bytes), the destiantion MAC address (ether_dhost, 6 bytes), and the type of Ethernet packet (ether_type, 2 bytes), which is used to determine if the packet is an IP packet.

-     As you know, it is not a good idea to show this information format to a regular user.  Your first task is to define the functions of the C++ class that defines the functions that translate the MAC address information into human readable strings.
