The key error message is
bind: Address already in use (98)
You can' set both accept and connect to the same port.

See if you can configure your jdbc app on the server to listen on loopback interfase, line 127.0.0.1:2404, then set accept=yourserveraddress:2406 and connect=127.0.0.1:2404

It was typo sorry. The settings on the server are: 

[test]
accept = 2406
connect = 2404

and on the client:

[jdbc]
client = yes
accept = 127.0.0.1:2404
connect = my_server_name:2406


I'm trying to start the service on the server and it's not working: 


/etc/init.d/stunnel start
Starting stunnel (SSL tunnel) startproc:  exit status of parent of /usr/sbin/stunnel: 1
  please see /var/log/rc.stunnel.log for details                                                                                                             failed


Regards,

In your before setting, your client should have  been to connect to your test server:

[jdbc]
client = yes
accept = 127.0.0.1:2404
 connect=my_server_name:2404

In your after setting, the accept and connect ports cannot be the same port.

Hi Jose,

Thanks for mail. The problem is that when I change the accept port on the server, stunnel doesn't start:

Before:

Server:

[test]
accept = 2404
connect = 2406

Client:

[jdbc]
client = yes
connect = my_server_name:2406

After:

I edited the stunnel.conf on the server:

[test]
accept = 2406
connect = 2406

Then trying to start the service:

/etc/init.d/stunnel start
Starting stunnel (SSL tunnel) startproc:  exit status of parent of /usr/sbin/stunnel: 1
  please see /var/log/rc.stunnel.log for details                                                                                                             failed

/var/log/rc.stunnel.log is empty but in the log specified in the stunnel.conf I have the following:

tail -10 /var/log/stunnel/stunnel.log

Same thing happens when I try to change the ports on the client. Any idea how this problem can be solved? 

Thanks and regards,
Daninho

The accept port on the server Config must be the same as the connect port on the client config.
The connect port on the server must be the port used by the application/service you try to secure, usually bound to the loopback interfase, as you probably don't want to allow unsecure connections.
On the client the accept port is the port your client application will connect to.

Hope this helps to clarify a bit.
