silent install of windows stunnel
by Laurent Licour 04 Aug '11

04 Aug '11

stunnel use NSIS as installer and it is possible to use /S switch to run silent install However, even in this mode, openssl configuration tools is executed and prompt for certificate informations. I think that executign this tools should be skip in silent mode -- Laurent LICOUR

stunnel OK without "transparent = source", with = timeout problem
by Elodie BOSSIER 03 Aug '11

03 Aug '11

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 30 Jul '11

30 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.
