I’m working on a side project that is a portscan utility written in VB.net. Here’s my progress so far, and it is working.
There’s some way to go on this little project. I think I can optimize it further, clean up the code, and fix my logic for many of the options. See an earlier post about handling command line arguments I wrote which is what class I use for handling the arguments.
Check out my C port scanner which is significantly faster (65k ports in < 30 seconds).
