Is there any software available that will listen for TCP packets and execute some event or (code, script, exe, etc) when packets matching a specific filter are detected?
To give you an example of what I'm trying to do. Say I have 2 web servers, one development and one for production. I want to be able to push a code update to my development server and replicate all of the requests hitting my production server onto the development server to test stress and concurrency.
There are other applications I've found that are very close to what I need but they lack one very important thing, Real-Time execution. I cannot record the TCP traffic then replay it at a later time, it needs to be done in real time.
Current setup (ii7 with haproxy)
