Anything above and including 1024 is "free to use" by anyone. OT: you may know this already, but the port in your example is that for HTTP web servers. Anything listening to this port should speak HTTP, too. A simple "hello world" does not suffice. ;-) share|improve this answer edited Dec 5 '13 at 10:07 answered Dec 5 '13 at 10:00 Linus Kleen 20.7k76183 It works on root. –user1345414 Dec 5 '13 at 10:13 1 @user1345414 Of course it works for root, that's the most privileged user you're going to find. That doesn't mean it's the right thing to do, though. –unwind Dec 5 '13 at 10:
