Hi All,
 
someone could help me to understand what happens and what my client needs to verify the peer?
 
Thanks&Regards
 
I configure stunnel in this way:
 
stunnel.conf
================================
client = yes
debug=7
cert = client69f.pem
key = chiave69.pem
cafile=cacert.pem
verify = 1
capath= .
    
[telnet]
accept = 23
connect = 10.36.3.191:4433
============================
 
I put all the files configured above in the same directory where stunnel-4.07.exe runs;
 
I have a machine in which  ssl server runs with a certificate signed by the same CA (cacert.pem).
 
The log file is :
