Bandwidth Monitoring TUI(bwdm)

bwdm is a simple CLI- and TUI-based bandwidth monitoring tool that allows users to monitor traffic by sniffing packets from a specified network interface. It displays real-time network using a graph, helping users visualize bandwidth consumption

NOTE : Please use this in adminstrator mode

Features

• Packet Sniffing: Capture and monitor network traffic from a specific interface.
• Graph Visualization: Displays real-time network bandwidth in a graphical format for easy analysis.
• Network Interface Listing: Lists all network interfaces for quick selection.
• Logging Packet data: Logging Packet data in a file

Installation

Prerequisites

• go (v1.18+)
• libpcap , required for packet caputring
• git

Clone the repository

git clone https://github.com/zokhcat/bwdm.git
cd bwdm

Build the Application

go build -o bwdm

Usage

List available network interfaces

Before capturing traffic, you can list all interfaces on your system:

./bwdm list

The output will be something like:

Available interfaces:
- eno1
- wlo1
- lo
Please specify an interface using the -i flag while using the capture command.

Start capturing traffic(for 10 seconds)

To capture network traffic from a specific interface for 10 seconds, use the capture command with -i flag:

./bwdm capture -i <interface-name>

For example:

./bwdm capture -i wlo1

This will sniff the packets on the wlo1 interface for 10 seconds and visualize the network bandwidth in a graph.

Options:

capture: Sniff packets on a specified network interface for 10 seconds and display network usage in a graphical interface

list: List all available network interfaces

Flags:

interface or i: sniff packets of a specific network interface

p or ip: sniff packets from a specific IP address

file or f: log the packet data into a pcap file

dst-port or p: Sniff packets from a specific port

protocol or t: Protocol filtering for packets

Future Todos:

• Packet Filtering such for specific IP address
• Advanced Filtering like port filtering and protocol filtering
• Packet Inspection Mode
• Logging Packet Data into a pcap file
• Show Realtime Geolocation IP
• Configurable capture duration(Maybe)
