Hello,

I need to know if there is a way for me to check if my ISP is blocking ports
WITHOUT CALLING THEM! I have called them, and they say no, but I don't
believe them. I am running Oracle and I cannot connect to my database.
This problem just all of a sudden started on my two servers that are on the
same ISP. HMMM? I have gone as far as reinstalling everything, even the
OS, reconfiguring the whole server and still nothing. Sooooo, I need to
know if I can check if they are blocking ports.

Thanks,

Daniel
 
The simplest way to test if a port is open is to telnet to
it using the port number (telnet host portnumber). You
won't be able to do much, but if you don't get a message
like "connection failed", then probably it is permitted.
