Hi,

The full logs of the client would be useful.

What are you trying to connect to (on port 41521) ?

Regards,

Flo

Hello,

I have stunnel v 5.55 on linux machine client e linux machine db server, Red Hat Enterprise Linux Server release 6.6. I have noticed that there are many many diconnections by side client (at the bottom of the page). Why there is this behavior?

This is the configuration file of client machine:

cert = /opt/stunnel-5.55/etc/stunnel/stunnel.pem
verify = 3
setuid = stunnel

CAfile = /opt/stunnel-5.55/var/certs.pem

pid = /opt/stunnel-5.55/var/lib/stunnel/stunnel_client.pid

socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

sslVersion = TLSv1

TIMEOUTconnect = 30
failover = rr

ciphers = ECDH@STRENGTH:DH@STRENGTH:HIGH:!RC4:!MD5:!DES:!aNULL:!eNULL

debug = 7
output = /opt/stunnel-5.55/var/stunnel.log

client = yes

[connessione_a_EMPRMDB1-DB2]
accept=127.0.0.1:10001
connect=10.56.213.70:41521
connect=10.56.213.72:41521
