The purpose of a simulator stress test tool is to test the performance of a network.
When combined with a network traffic generator, it can give you insight into how a network will cope with varying levels of stress and load. A stress test tool can also be used to identify issues like slow-loading or unresponsive web pages. Below are my rankings for the best network traffic generators and network stress test software, free and paid. These have been designed to cover everything from network discovery and configuration to monitoring and troubleshooting.
WAN Killer was designed to assist users in identifying and targeting specific network traffic. It does this by facilitating the generation of your own traffic. You can define a specific IP address or hostname, which the tool will then intentionally bombard with traffic.
This process will give you insight into your network performance. You can even define the size and circuit bandwidth percentage, then create data for your WAN tests.
WAN Killer is a flexible tool allowing you to adjust port numbers, packet size, and bandwidth percentage, as well as modify the Differentiated Services Code Point and Explicit Congestion Notification settings.
The launch process is quick and easy. When combined, these tools enable you to effectively manage, troubleshoot, and monitor your entire network. Each one is easily accessible and contained within a single desktop console.
There are some truly impressive tools in this bundle. It can also track availability of devices, utilization of memory, CPU load, the performance of network paths, the latency of network paths, and interface stats. I especially like the topology maps and other graphical representations, which include pie charts and line graphs. Packet Sender is a free, open source application with no advertisements and no bundles. Servers and clients can run at the same time, so you can test in a streamlined and undisrupted way, and all data can be defined, whether in ASCII or HEX.
This is a cross-platform tool for Windows, Mac, and Linux. Packet Sender uses a command line and a GUI, providing a lot of flexibility in terms of the interface you use. Packet Sender can be used for a range of activities, including the automation of testing through the use of its command-line tool and hotkeys.
Even firewalls and connectivity can be tested. The tool accomplishes this by getting packet senders to communicate with each other. By providing portable packet senders with predefined settings and packets to customers, Packet Sender is also a means of supporting tech. In addition, it allows you to conduct security research by sending SSL and then analyzing the resulting traffic log. Packet Sender, available on GitHub, is a great way of controlling network-based devices with minimal manual input and labor.
The network generator utility is an effective means of stress-testing devices, and you can use the cloud service to share, save, and collaborate. I like Packet Sender cloud for the way it facilitates collaboration.
With it, you can even publicly display and distribute packets for collaboration, tutorials, and utilization by end users via URL. Packet Sender offers mobile applications for both iOS and Android. Overall, Packet Sender is an effective network traffic generator and analyzer. However, free and open source tools come with several disadvantages.
Still, if you want to give Packet Sender a try, downloading it is zero risk. Nping is another popular open source program for network packet generation, response analysis, and response time analysis.
With this tool, you can create your own custom packets for flexible protocol testing. Protocol headers can be configured to your liking, allowing you to essentially fine tune your testing approach. Nping is multifunctional, being both a ping tool and great for RAW packet generation, denial-of-service attacks, tracert, and ARP poisoning.
Essentially, this mode breaks Nping down into two elements—the echo server and the echo client. This tool is open source and offers command line interface to work with. Mausezahn is a fast traffic generator tool that lets you send every possible kind of network packet.
This tool is used for penetration testing of firewalls and IDS but you can decide to how to use this tool effectively in your network to find security bugs.
You can also use this tool to test if your network is secure against DOS attack. Notable thing about this tool is that it give you full control over NIC card. This tool is also an open source tool with command line interface.
These are a few of the best free tools for packet crafting. I will recommend you to try all tools to check how these tools work. As I already mentioned, you must learn about networks, network packet layers, packet structures, headers and other necessary things before using these tools. If you know everything about these, you will be able to perform better attack and create better defenses against these attacks.
Packet crafting is one of the best ways to perform network penetration testing. You can try creating layer of security and then try again to break your own security.
In this way, you will be able to prevent hackers to exploiting vulnerabilities in the security mechanism you created. Hackers always try to intrude into the internal network of companies. In recent months, we have seen so many attacks against big companies. In most of the cases, internal network hacked to access confidential information. Therefore, network security is one of the most important tasks in any business.
So, learn packet crafting and learn these tools. The more you learn, the better security person you will become. All these tools are created for special purposes. You can try these tools to modify packets to test the firewall rules and break the security.
Note: We do not encourage use of these tools to test the security of a network without getting prior permission. Most businesses use proper security and tracking. If you caught attacking a network, you may be booked under cyber-crime laws in most countries. The purpose of this article make you aware of tools for learning purpose.
