This TIME_WAIT is necessary in case the ACK you sent wasn't received, or in case spurious packets show up for other reasons. How to mix correctly? Then again, maybe this is a perfect opportunity to learn to use it. Source Should I serve jury duty when I have no respect for the judge?
If I've somehow mistaken the nc return value and it returns false even if it can secure 8140 locally but the target port is closed, that is easily handled with a Iometer Error Binding To Socket I have two virtual hosts configured using port 80, but Apache will not start.

After a few tests, every single free port less than 1024 was stuck in TIME_WAIT and I couldn't proceed. share|improve this answer answered Sep 7 '15 at 14:12 user974407 48056 Yes, you could change the port number to whatever port is being blocked.
