Make sure a few things:
1. The remote host is listening on the port you are trying to connect
to (often 80, or 8080)
2. The host you are connecting to is reachable from the host you are
on. (using ping, for instance)
3. You are specifying the correct host name and port.

Hope this helps. Good luck.

To check if a server is listening at a particular port or not - you
have to follow the following steps in the command prompt:

telnet <server-name> <port>

Note: the port for http protocol defaults to 80 and that for https
protocol defaults to 443.

Cheers,
Jan

You should probably forget about pinging. The telnet advice than Jan
gave you is better. Pinging might give you a false negative if the server is
configured to ignore pings.

Hi,

When i trying use it by means of telnet the connection is refused,
so is that i might be behind proxy. Or wht could go worng in this. In
httpunit they just given the the url directly as "www.meterware.com" to
get the response when i try to do it, The error pops. Is there anything
they were missing in explaining this, is so let me know it

cheers,
Arun.

You say you can reach this remote host using a web-browser? Does the
web-browser have a local http-proxy configured?

In Internet Explorer, select the "Tools" menu, "Internet Options",
"Connections", "LAN Settings" and see if the "Proxy" is ticked.

Well, from where I'm sitting

- ping works
- I can telnet to port 80
- my browser can fetch the main page

You'd better check that you aren't using a proxy and/or being blocked by
a firewall on your site.
