I can create a cross platform application that can listen to a port and save everything on anything you want. I can do it on a text file or insert it to a database.
I can create a python script that can do this for you. Or If you don't want to install python(on windows because windows does not come with it) I can create it using Googles new programming language Go and compile it for any platform you want.
I am new to this site, so I am looking forward this to be my first job.
You will not be disappointed with what I will do.
Regrads, Gebriel.
