Using Client Socket - Getting Basic Error

[scripter73]

I was working through a tutorial on Sockets. I'm just now learning about them. I copied this code from a site. It says I should receive the time, but I get an error. What's wrong? I think the connection timed out, but when I ping the address, I get a reply. Please help. I have tried to run several examples, and I haven't gotten anything back yet from any of them.

======
CODE
======

import java.io.*; // These two are needed for socket support
import java.net.*;

public class Client
{
public static void main(String args[])
{
try
{
Socket s = new Socket("time-A.timefreq.bldrdoc.gov", 13);

BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));

String line;
while(( line = in.readLine()) != null)
System.out.println(line);
}
catch(IOException e)
{
e.printStackTrace();
}
}
}

Hey there,

I am running java 1.4.1 on redhat 7.1. I compiled and ran your code first try with no problems.

Maybe try to run it again at another time during the day???

Hi scoon,

That's what the Webmaster suggested. I waited again until this morning, and I'm getting the same thing, "Connection timed out", so I'll just keep trying.

I got another tutorial to work, though, so at least I have seen socket programming operate.

Thanks for your help,
