Python implementation of Ping, Traceroute and SSID scanner.

Environment:

• Linux (root privileges)
• Python 3

What's inside?

The repository contains implementations of the following networking tools:

• Ping
• Traceroute
• SSID scanner
• ARP requester

All the below frames are written from scratch according to RFC specifications:

• Ethernet
• ARP
• ICMP
• IP
• UDP

Usage:

All the tools need root privileges to run. Ping and Traceroute require network settings for ARP request to be filled, before they can start working.
These are: INTERFACE, SRC_IP, DEST_IP, SRC_MAC
When it's done, they work in a similar manner to their standard OS counterparts.

• Ping

sudo python3 ping.py github.com

• Traceroute

sudo python3 traceroute.py github.com

• SSID scanner

sudo python3 ssid_scanner.py wlan0 0.5

SSID scanner takes interface name and time interval as an input. Interface has to be able to work in monitor mode.
Time argument determines how long the script should sniff each channel.

IEEE 802.11 frames are examined in order to figure out if there are any beacon, probe requests or probe response frames inside. If so, then such a frame is further processed and SSID info is extracted.

The script prints out info about SID, BSSID, MACs, signal, channels and counter of received packets. The output is "grouped" by unique packets and contains "Pkts" counter field. It's ready for further analysis and may be helpful in choosing the best channel or just getting insight into surrounding network traffic.

Output example:
Channel  Src MAC            Dest MAC           BSSID              Signal   Type     Pkts   SSID
