A simple packet sniffer written in summer 2015 using Qt for the gui and Pcap to sniff ethernet packets. Originally written in pure C as a command line application, then adapted into a GUI application. Can save, pause, resume, open, and delete captures.
Demonstrates knowledge of networking layers and protocols.
Has support for following Protocols:
-
Layer 2 - Data Link Layer:
- Ethernet
- ARP
-
Layer 3 - Network Layer:
- ICMP
- IPv4 and IPv6
-
Layer 4 - Transport Layer:
- TCP
- UDP
-
Layer 7 - Application Layer:
- DNS
- HTTP
- HTTPS
Depends upon the following packages:
- libpcap-dev
- qt5
Please compile by importing the PacketSniffer.pro file into QtCreator, building it,then navigating to the build directory and running the executable using:
sudo ./PacketSniffer
If there is an error in the status bar at the bottom of the window when starting capture, please edit the ETHERNET_DEVICE string in shared.h (use the command "ifconfig" to view your ethernet controller names) and recompile (sorry for how crude this method is, cut me some slack I made it years ago).
