Network topology scanner

✔️ Working

⚠️ Historical Project

This utility is developed as an undergraduate mini-project. Its source-code does not adhere to standard conventions/practices and needs refactoring. I've tried to tag the areas where refactoring is needed, consider going through those before using this.

Functionality

• The tool asks user to enter start and end IP address, and scans the range to find out the topology with respect to host machine.
• It then draws a tree-based representation of the topology with host machine at root. Other network devices are shown at levels based on the number of hops between them and the host.

Implementation

• The tool uses MyTraceRoute(mtr) and nmap utilities to perform network scan.
• It uses a binary-search based scan-heuristic to minimize unnecessary scans.
• Basically, it determines which IP addresses to scan from the given range, so that the scan-count and latency will be minimized.

Dependencies

• Current version works on Linux only
• Needs pre-installed mtr and nmap utilities
