Simple and powerful golang port scanner
Who needs any other port scanner when you can take this one file and compile it to run on both Linux and Windows? And better yet, change the number to workers from 5 to 300 now you can scan an entire /24 network in 3 seconds.
Note that the program seem to have an issue with "\r" and "\n", which suggests that the program may have been developed on a Mac. No problem, simply replace swap "\r" and "\n" in the source and you are ready to go.
