Laurent,
We need to present a client certificate to the server. That's the important part
missing. Do that by adding -cert your_cert_filename to the command, like:
openssl s_client -ssl3 -state -cert your_client_cert_filename -connect
your-stunnel-ip:10443
See http://www.openssl.org/docs/apps/s_client.html
Regards,
Jose

:SSL3_GET_RECORD:wrong versionnumber with cipher DES-CBC-SHA
Laurent,
Ideally, you should terminate the SSL connection on your final server. But
that's not the problem here. It should work as is.
Mosty likely the problem is on the client SSL software you are using to connect
to stunnel. The cipher you are trying to use DESC-CBC-SHA works with SSLv3 and
TLSv1. Can you force your client to use those protocols? Maybe it is trying to
negotiate SSLv2. Also are you sure it is speaking SSL instead of plain text?
You can test your connection to stunnel server with openssl s_client command.
Example
openssl s_client -ssl3 -state -connect your-stunnel-ip:10443
openssl s_client -tls1 -state -connect your-stunnel-ip:10443
if this works, we found the culprit.
Regards
Jose

:SSL3_GET_RECORD:wrong versionnumber with cipher DES-CBC-SHA
Jose,
I use 2 servers in my configuration:
the first one who listenning on the port 10443 (where we receive encrypted
traffic from software using ssl)
and the second one who listenning the port 10016 (where we receive decrypted
traffic).
The first one receive the encrypted traffic, it decrypted it and send it to the
second server that's why i only use the server mode on my fist server.
Do you think that i also need to change this configuration?

Laurent,
I'm not sure you are connecting the dots right.
I see an stunnel server configuration. In this case, your stunnel is a front-end
to a service you run on host XXXX port 10016. What is that service? Is stunnel
running on the same host? Note that If stunnel is not running on the same host
with IP XXXX, then you may have some traffic in clear text in your network (from
the device running stunnel to the device hosting the service on port 10016).
You need a client to connect to the stunnel server. Unless your client support
SSL natively, you also should have an stunnel running on your client device with
entries like these:
client=yes
[pestip]
accept = 10443
connect = Your-Stunnel-server-IP:10443
In this case your client apps connects locally to port 10443, traffic is
encrypted and sent to your server listening on port 10443, where it is decripted
and send to IP XXXX port 10016.
Regards,
Jose

Dear Jose,
here is the configuration file of my stunnel :
; Sample stunnel configuration file by Michal Trojnara 2002-2006
; Some options used here may not be adequate for your particular configuration
; Please make sure you understand them (especially the effect of chroot jail)
; Certificate/key is needed in server mode and optional in client mode
cert = /opt/freeware/etc/stunnel/ca_nopass.pem
foreground = yes
syslog = yes
; Protocol version (all, SSLv2, SSLv3, TLSv1)
;sslVersion = SSLv2
sslVersion = all
;ciphers = DES-CBC-SHA
;ciphers = DES-CBC3-SHA:IDEA-CBC-MD5
; Some security enhancements for UNIX systems - comment them out on Win32
;chroot = /usr/local/stunnel/var/lib/stunnel
;chroot = /tmp/
;setuid = root
;setgid = other
; PID is created inside chroot jail
pid = /var/adm/stunnel_server_level1.pid
; Some performance tunings
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
;compression = rle
; Workaround for Eudora bug
;options = DONT_INSERT_EMPTY_FRAGMENTS
;options = Options_SSL
; Authentication stuff
verify = 3
; Don't forget to c_rehash CApath
; CApath is located inside chroot jail
CApath = /opt/freeware/etc/stunnel/CA_files/
; It's often easier to use CAfile
;CAfile = /opt/freeware/etc/stunnel/ca.pem
; Don't forget to c_rehash CRLpath
; CRLpath is located inside chroot jail
;CRLpath = /crls
; Alternatively you can use CRLfile
;CRLfile = /usr/local/stunnel/etc/stunnel/crls.pem
; Some debugging stuff useful for troubleshooting
debug = 7
; Use it for client mode
client = no
; Service-level configuration
[pesitip]
accept = 10443
connect = XXXXXXX:10016
Thanks for your help.
Regards.

Laurent,
Can you post your configuration? For security, You should change the real IPs
(but not the ports) before posting.
You can check:
1. Does your stunnel client config has client=yes?
2. Does your stunnel server config has client=no
3. Check your packet flow, that is: your accept/connect settings.
Regards
Jose
