<p></p> <p><b>New page</b></p><div>You&#039;re unsuccessfully trying to connect somwhere. You&#039;ll need to know the [[DNS]] or [[IP]] of the server hosting the [[daemon]], as well as the [[Ports|port]] number it listens on. <br /> <br /> In our example, we&#039;ll try to connect to port 80 of hackepedia.org. (The common www port, often hidden in your [[Browser]]).<br /> <br /> * Can you resolve [[DNS]]?<br /> * Can you [[ping]] the server? (Verifying the machine is up)<br /> * Do you have to allow outbound access to this port on your [[firewall]]? on your [[router]]?<br /> * [[telnet]] to the port<br /> <br /> $ telnet hackepedia.org 80<br /> Trying 64.111.114.195...<br /> Connected to hackepedia.org.<br /> Escape character is &#039;^]&#039;.<br /> <br /> This tells me that the port is listening. Just for fun, here is an example showing that there is no [[daemon]] listening on port 79 of this server:<br /> <br /> $ telnet hackepedia.org 79<br /> Trying 64.111.114.195...<br /> telnet: Unable to connect to remote host: Connection refused</div>
