Net Config

A simple command-line tool to configure network latency and bandwidth limits on the local loopback interface for testing and development purposes.

Features

Add configurable latency to the loopback interface
Set bandwidth limits (optional)
View current network configuration status
Easily disable all network modifications
Simple command-line interface

Requirements

Linux/Unix-like operating system
sudo privileges (for modifying network settings)
tc (traffic control) command-line tool

Usage

The tool provides three main commands:

View Current Status

./net-config.sh status

This will show the current queue discipline and class settings on the loopback interface.

Add Latency and/or Bandwidth Limit

./net-config.sh on <latency_ms> [max_mbps]

latency_ms: Required. The latency to add in milliseconds
max_mbps: Optional. Maximum bandwidth limit in Mbps

Examples:

# Add 100ms latency
./net-config.sh on 100

# Add 1ms latency and limit bandwidth to 1 Gbps
./net-config.sh on 1 1000

# Add 50ms latency and limit bandwidth to 10 Gbps
./net-config.sh on 50 10000

Remove Network Modifications

./net-config.sh off

This will remove all network modifications and restore the default settings.
