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

• 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

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

The tool provides three main commands:

./net-config.sh status

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

./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

./net-config.sh off

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