Now this is sneaky! I would never have thought of this. I was under the
impression that 127.0.0.1 is always local host, never "remote machine"
Well, under certain circumstances it can be "remote machine",
SSH tunneling OP tries to use is one bold example.
Putty Configuration:
Listen: 1500
What is "Putty" listetning to?
To your connections on local TCP port 1500, so that you
make a connection to localhost:1500 and PuTTY tunnels
it to configured remote host and port, encrypting and
compressing it on the way, and tunnels back remote's
responses.
Pass to: <remotemachineIPaddress>:1521
What is that? Get yourself a DBA who knows basic networking and have him
configure your PC. your configuration is so mixed up that it cannot
possibly work.
It's not really messed up and it can work just fine - I routinely use
SSH tunneling in similar way to communicate to remote applications
and databases securely, however there is probably something wrong
on remote side in OPs' case. Without knowing more about remote
host config it's hard to tell exactly what is wrong though... If it's
Windows, I probably know what's wrong, but if it's something else
then more meditation is required to see the truth, maybe even
some woodoo and dances with tambourine around the hardware... :)
