[stunnel-users] issue with running stunnel

Sun Mar 18 01:13:40 CET 2012

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
