a simple sniffer and a port analyzer
In order to run network sniffer, run the following commands:
sudo ifconfig <interface> promisc
sudo python3 main.py
This network sniffer does not support all of the protocols. Some of the protocols supported are HTTP, ICMP, DNS and ARP.
In order to run port analyzer, netifaces module should be installed. To run the port analyzer, run:
python3 main.py dst=<destination> delay=<time to wait for response> mode=<mode> iface=<network interface> ports=<range of ports>
Availabe modes are:
- s: SYN scan
- c: Connect scan
- f: Fin scan
- W: Window scan
- a: ACK scan
For example you can run the following command to scan all open ports in range 70-90 from example.com:
python3 main2.py dst=example.com mode=s ports=70-90 iface=wlp2s0 delay=1
which outputs:
---Target: example.com---
---SYN scan---
---Range of ports: (70, 90) ---
---interface set to wlp2s0---
---Delay: 1.0---
