[stunnel-users] SSL_read: 1408F455: error:1408F455:SSL

Hi, someone could help me?

I am using stunnel (4.07) as ssl client to do telnet to my router with ssl server (openssl 0.9.7d).

Stunnel is configured in this way:

==========================
client = yes

debug=7
cert=clcert.pem
[telnet]
accept = 23
connect = 10.36.3.144:4433
==========================

My router's configuration is:

==========================
-Verify 4
-cert cert.pem
==========================

The exchange of packets:

==========================
client sends=======> Client Hello
server sends======> Server Hello,Certificate, Certificate Request,Server Hello Done
client sends======> Certificate, Client Key Exchange, Certificate Verify, Change Cipher Spec, Encrypted Handshake Message

server sends=====> Change Cipher Spec, Encrypted Handshake Message and then Application Data.

After sending a number of Application Data by the server, client sends Encrypted Alert and closes the connection.
Having debug on stunnel client I can see:

This client is now running using an updated library: libeay32.dll obtained compiling openssl-SNAP-20050304 that seemed to be the solution of the
problem (after searching on Internet I deduce that).

Not having solution to the problem, I know that my conclusion is not right. So if someone knows how to procede, please help me.



Thanks&Regards
