UPDATE: Ostinato 0.9!

This tool came to my rescue yet again today! If you remember, I had blogged about this tool in my older post titled – Ostinato: The Network Traffic Generator and Analyzer! As always, before using any tool I tried to update it and there it was – Ostinato 0.9. This update was released long ago, but I missed it and hence this post. Infact, this open source tool was also awarded Best Product & Startup Demo at COMSNETS 2019!

Ostinato 0.9

What is Ostinato?

Ostinato is an open source packet generator and network traffic generator with a friendly GUI. It also is a powerful Python API for network test automation. Think of it as “Wireshark in Reverse”.

This is brief is the change log for the updated version:

  • Per stream statistics
  • Support for IPv4 options field (as a hex string)
  • Ostinato command line options and params

I can hardly wait for Ostinato 1.0, which seems to be arriving pretty soon!

Download Ostinato 0.9:

Even though the source code for this tool is available, if you want you can buy pre-built executable’s, ISOs or even appliances. More information about these releases is available here. Otherwise, download the Ostinato 0.9 source code here and compile it yourself.

Electron is a pretty recent framework for building desktop applications and there are not many tools that deal with the security part either. There is a electronjs security checklist, providing guidelines for building secure applications, but there is no tool per-se – atleast none I know of! Electronegativity changes this.
