I need to know if anyone can recommend to me a VERY solid TCP/UDP port scanning piece of software?
I need to run this on various network items that I have (some PCs, some not PCs) ... I know what port
I am looking for, and if it is NOT open on the 'box', then I know something is not set right.
The problem I've found so far is that MOST port scanners are the SAME for TCP, but they mostly fall short
when scanning for UDP ports? Why is this?
What is the difference when scanning port .... why are the methods used?
What is the difference between scanning for open TCP ports vs. UDP ports?
Why is it that there a lots of options for scanning TCP ports (most all programs have the same options), but
when it comes to properly scanning for UDP ports ... some scanners list the UDP port open and others do NOT?
Thanks in advance for your time and any reply!
