Question : verify port connection

As we know, we can check whether a network allow to go through the smtp or pop port by telneting to them. Is the any command that we can check whether we can reach the http port 80.

I do not want to use software to verify such as IE or Netscape.

Ping can only make sure the host is still alive, but cannot verify the port 80 has been opened.

Answer : verify port connection

Try "telnet www.yahoo.com 80" and then type "GET /". If you get html back then there is a webserver there.
