The telnet advice than Jan gave you is better. Pinging might give you a false negative if the server is configured to ignore pings. - Oliver 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. > <arunkumar....@gmail.com> wrote in messagenews:1163050910.595774.53960@b28g2000cwb.googlegroups.com... > [quoted text clipped - 5 lines] > > - Oliver > Hi, > [quoted text clipped - 3 lines] > 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 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.

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. are you behind a NAT device? (linksys/netgear/dlink type router?) Yes i am behind Network Adapter Translation, is it possible to get the response when we are behing NAT device. If possible let me know it. Thanks > are you behind a NAT device? (linksys/netgear/dlink type router?) How to make sure the remote host is listening to the port i am connecting, iam just giving the url from which i want the response. Its really help full to trace the bug. Thanks Arun > > Hi all, > > [quoted text clipped - 18 lines] > > 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.

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.
