User Reviews

  • Finally a packet replay and editing tool that simply works on all major platforms and command line (can be used in scripts, ..) Perfect for testing during development and validation phase. I was looking for a packet replay tool, continuous looping multicast data feeds for debugging and testing radar data feed quality monitoring tools. Great work guys !
