Hi again Dewen;
It sounds to me like Stunnel isn't being accessed at all. You should be
seeing something in the
Stunnel log window. I run Stunnel under Windows, so what I generally do
is get Stunnel to listen
to the loopback interface at address 127.0.0.1, or some other address
within the loopback interface
range. As such, if I was attempting to access it with a utility like
Netcat, my basic stunnel.conf would
look something like this for the client side:
debug =7
[service.name]
client = yes
accept = 127.0.0.1:12035
connect = destination.address:1230
Then, I would point Netcat to the listening address and port. In your
case, that might be netcat 127.0.0.1:12035.
Then see if Stunnel logs your connection attempt.
Again, this is under Windows, so your mileage may vary.
Let us know how it works out for you.
Regards;
Thomas

I don't know anything about Netcat, so I'm taking a
stab in the dark here, but it looks as if<br>
you're pointing Netcat at port 1230, while your
config file indicates that Stunnel would be <br>
listening on port 12035. Try redirecting Netcat to
the listening port.<br>
<br>
If you need to post again, please indicate the
