java.net.ConnectException: Connection timed out: connect

[Guy Ka]

Hi,
I have the following piece of code mostly from the java tutorial at
http://web2.java.sun.com/docs/books/tutorial/networking/sockets/readingWriting.html
When running this code, I get the ConnectException error. I can actually
ping all the IP addresses that I assign to the variable "myhost" (one of
them is my locoal machine). Two of these machines run WinXp while one of
them runs WinM. Do I need special user rights to access the echo service
under windows?
Thanks for any hint. Guy

out.close();
