To be honest i do not know your application, but:

this looks like you have to do some configuration work in your application. For a host to open a connection it has to have a daemon running which is listening to the port where the connection is attempted.

For instance: let's say you contact a web server. This means your browser creates a message, sends it to the target server, port 80 (or whatever is configured, but 80 is the default). Behind port 80 on the target server lurks the web server process (Apache, ...), which picks the message up, does something and sends a message back (like: serves up a web page). If the web server would not listen behind port 80, nothing would happen at all - the host would "refuse the connection".

This is why i think you simply have nobody listening behind port 1521, so that no connection comes to pass.

I hope this helps.

NAME
serverping - check the status of an XEvil server SYNOPSIS
serverping [-count num_tries] [-timeout timeout_ms] server_name[:port] DESCRIPTION
serverping is a simple utility to give you information on an XEvil server, such as the game style, who is playing, and how well they are doing. OPTIONS
-count num_tries specify the number of pings to send before giving up, default=3 -timeout timeout_ms specify the time in milliseconds to wait for a response before giving up, default=1000 server_name[:port] specify the server name or IP address, optionally with port, default port is 6066 EXAMPLES
serverping whitehouse.gov This will give you the game status of the XEvil game running on the server at whitehouse.gov, at default port 6066. It will try 3 times, and wait 1 sec per try. At the time of this writing, whitehouse.gov is not running an XEvil server. serverping -timeout 5000 292.43.199.64:9999 This will give you the game status of the XEvil game running on the server at 292.43.199.64, at port 9999. It will try 3 times, and wait 5 sec per try. 292.43.199.64 is not a valid IP address. GAME AUTHOR
