Greetings again, Thanks so much to have updated the manual about SNI, my stunel works correctly. But i have a tiny problem, when i visit my webserver, the SERVER['REMOTE_ADDR'] with PHP isn't the ip adress of the visitor but the IP of the stunnel. I have read the manual about this transparent proxy and i don't sucess with the configuration. This is my config file : pid = /stunnel.pid options = NO_SSLv2 transparent = source [virtual] accept = 443 cert = /usr/local/openssl/etc/CERTIFICATES/www.franceserv.fr_cert.cert key = /usr/local/openssl/etc/PRIVATE_KEYS/www.franceserv.fr_key.pem connect = www.franceserv.fr:80 [sni1] sni = virtual:elodie.franceserv.com cert = /etc/ssl-fsh/cert-elodie.franceserv.com.pem key = /etc/ssl-fsh/key-franceserv.key connect = elodie.franceserv.com:80 [sni2] sni = virtual:befun.franceserv.com cert = /etc/ssl-fsh/cert-befun.franceserv.com.pem key = /etc/ssl-fsh/key-franceserv.key connect = befun.franceserv.com:80 It's don't work, i have a timeout with my browser. With iptables, i have set this : iptables -t mangle -N DIVERT iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT iptables -t mangle -A DIVERT -j MARK --set-mark 1 iptables -t mangle -A DIVERT -j ACCEPT ip rule add fwmark 1 lookup 100 ip route add local 0.0.0.0/0 dev lo table 100 echo 0 > /proc/sys/net/ipv4/conf/lo/rp_filter echo 1 > /proc/sys/net/ipv4/ip_forward My stunnel is on the server 192.168.0.20 and the webserver on 192.168.0.2 I try to follow the help of http://www.stunnel.org/static/stunnel.html#service_level_options with : transparent = none | source | destination | both (Unix only) Could you tell me what i make wrong please ?

Failed to run 2 instances of windows service (error 1053)
by Laurent Licour 03 Aug '11

03 Aug '11

I have to run at the same time on the same windows host, 2 instances of stunnel : a client instance and a server instance I have 2 config files : stunnel-client.conf , stunnel-server.conf Each configuration works, but not at the same time. I can install 2 services (with differents service name), but i can't start both services at the same time. I have to stop the first one to start the second one stunnel.exe -install stunnel-client.conf stunnel.exe -install stunnel-server.conf stunnel.exe -start stunnel-client.conf stunnel.exe -start stunnel-server.conf --> error 1053 stunnel.exe -stop stunnel-client.conf stunnel.exe -start stunnel-server.conf stunnel.exe -start stunnel-client.conf --> error 1053 It is also not possible to start the both configurations directly (no service mode). test run with stunnel 4.42b2 on windows XPe and Win2008R2 -- Laurent LICOUR

What do your stunnel configuration files look like? Other problem: mysql client may decide to use a local domain socket when connecting to localhost, thwarting your attempts to go via Stunnel. You might want to 'strace mysql ...' and look for the connect() lines. -- Brian Hatch Time flies like an Systems and arrow.

DH parameters
by yyy 31 Jul '11

31 Jul '11

Hello! How to specify custom DH parameters? There is an option for specifying ECDH curve (curve option), but not for ordinary DH. Searching man page for "DH" did not yield anything. Searching this list archive for "DH paramaeters" found only some default error messages.

Issue with -quiet option (Windows 2000 Server SP4)
by rtr purchase 25 Jul '11

25 Jul '11

Hello, Thank you for STunnel. I've been using BLAT command line mailer for years at a client's site to send system status messages to me. Recently the client switched to ATT's SSL protected email. Blat does not support SSL. STunnel to the rescue. I started with ver. 4.39. I wanted to start and stop the STUNNEL service via script commands but found that the -quiet switch did not suppress the OK message box consistently. This naturally stopped the script from continuing. This was true of both the -start and -stop functions but was more of an issue with the -stop function. While looking through the documentation to see what I might be doing wrong, I saw that 4.40 was released (the day after I downloaded 4.39). 4.40 has the same issue with the -quiet switch but the addition of the -exit switch allowed me to start and stop STUNNEL without running it as a service. Great timing! I had tested my scripts using a Windows 7 machine where they functioned as expected. It was only when I moved them to the client's Windows 2000 Server (SP4) that this issue appeared.
