Hello there, I'm currently practicing network programming under Unix system. I have here a sample code from the tutorial. I compiled it, it has no errors. But when I execute it, it prompts me this "connect: Connection refused". What do you think is the problem. Here's my code:
At first glance you are trying to connect to port 13. At least what the constant says. Try 80 as port to connect to and it should work. Also check out your firewall settings if they block the port you are trying to connect to.
Just a question did you compile with the option --wall. It also gives you all the warnings during compile
You cannot just arbitrarily choose any port number; the server must be expecting connections on that port, otherwise it will refuse the connection. 80 (=www) would have been a good wild guess. 13 or 50 not so. -- But you shouldn't have to guess, you should *know* which ports are open.
