NetLab is a Go-based program designed to create isolated network environments using network namespaces. It provides the capability to limit bandwidth and monitor traffic within these environments. This tool is particularly useful for network engineers and developers who need to test applications or services in a controlled network setting.

Isolated Network Namespaces: Create separate network namespaces to simulate different network environments. Bandwidth Limitation: Specify upload and download bandwidth limits for each namespace. Internet Connectivity: Option to set up NAT for external internet access from within the namespace.

Traffic Monitoring: Keep an eye on the network traffic that flows through the namespace. Installation

Before you can use NetLab, you need to have Go installed on your system. You can download and install Go from the official website: https://golang.org/dl/.

Once Go is installed, you can install NetLab by cloning the repository and building the program:

git clone https://github.com/yourusername/netlab.git
cd netlab
go build

Usage

sudo ./netlab create --ip 192.168.137.5 --name test02 --int true -u 100 -d 100

Command-Line Arguments --ip: Assign an IP address to the namespace. --name: Set a name for the namespace. --int: Enable NAT for internet access (set to true or false). -u: Set the upload bandwidth limit in kbps (Kilobits per second). -d: Set the download bandwidth limit in kbps (Kilobits per second). Example The following example command creates Terminal inside of network namespace named net-lab-test02 with an IP address of 192.168.137.5, NAT enabled for internet access, and bandwidth limits of 100 kbps for both upload and download.

This will create a new bash terminal inside a namespace with a limited speed, to exit the terminal inside the namespace just run "exit".

open other new terminal (no inside of bash namespace) and run:

sudo ./netlab  monitor --name test02

NetLab requires the following dependencies to be installed on your system:

iproute2: For network namespace and traffic control. iptables: For setting up NAT if internet access is required.

NetLab must be run with superuser privileges to manage network namespaces and iptables. Bandwidth limits are approximate and depend on the underlying traffic control system.
