[stunnel-users] Stunnel and SSL

Mon Dec 12 16:17:04 CET 2011

Hi Mike,

A quick question, I am trying to create a SSL connection using stunnel and the following configuration;

debug = 7
output = stunnel.log
;cert = FCAXV_HamfbaaStkhlm1.pem
key = FCAXV_HamfbaaStkhlm1_key.pem
[SSLHOST]
;Use it for client mode
client = yes
accept  = 127.0.0.1:2525
connect = <server-ip>:10170

And I am getting following log after starting the Stunnel. Does following "Configuration successful" message in the log means that I have established a SSl connection? I am wondering about this because I have not provided any password for the certificate-private key, infact I do not know to do that as well. Can you please explain;
