Config for client proxy https (privoxy + stunnel)
by Xavier Cheney 31 Mar '06

31 Mar '06

Hi, I wan to customize web page before viewing by my browser Firefox. With "privoxy" (www.privoxy.org) I can modify (proxy filter) HTTP web page, but not HTTPS pages. So, I want to use stunnel, to transfer HTTPS in HTTP between my proxy and server, like this : browser (8118) <-> (8118) privoxy (8888) <-> (8888) stunnel (server:443) <-web-> server This is my stunnel.conf : ---------------------------------------------------- ciphers = RC4-MD5:DES-CBC3-SHA verify = 0 debug = 7 client = yes [https] accept = 8888 connect = server.server.com:443 TIMEOUTclose = 0 ---------------------------------------------------- And my log : ---------------------------------------------------- 2006.03.31 11:40:02 LOG7[3396:2944]: RAND_status claims sufficient entropy

Stunnel client failed to connect to a server?
by Xia David You -X (xiyou - Varite Inc.＠Cisco) 31 Mar '06

31 Mar '06

Hi, I have a client which is build on stunnel which is failed to talk to a secured server while we can connect to the server with IE as client. We have both Server certificate and Client Certificate. From looking the log, it appears that the IE also got the same failure in the first step, but it did not give up and tried again with "2 1 0.0470 (0.0470) C>S SSLv2 compatible client hello" and successed. so what did we do wrong here? some extra openssl library need to be built in? thanks David Both Sever side SSL dump attached (IE client and Stunnel client).

unpublished Ceritificate
by Happy Manocha 28 Mar '06

28 Mar '06

Hi all, I am a newbie with Stunnel. Can anyone let me know how can I configure my client for a server , which does not have published certificate. Though I am able to connect but it gives a warning message "The server you are connected to is using a security certificate that could not be verifed...etc". Is there any way to avoid it? An early response will be appreciated. Regds Happy Manocha

stunnel runs in background but fails to do his job
by christof mestdag 19 Mar '06

19 Mar '06

hi, i'm having difficulties using the stunnel program. I've got some help to change the syntax from 3.X to 4.X but it doesn't work. I've got this config file -> client=yes output=/var/log/stunnel.log [ldaps] accept=localhost:389 connect=192.168.1.101:636 I run it with /usr/sbin/stunnel ./stunnel.conf -> check background: ps -ef | grep stunnel root 3270 ..... /usr/sbin/stunnel ./stunnel.conf Problem is when i close on server gate 389 i can't get any input. I expect the traffic going towards port 636 on server but it doenst. I can close port 636 and open just 389. He keeps sending everyting towards 389. I also tried to create a stunnel.conf by using make stunnel.conf in the tools directory ( in you tar.gz ) but nothing changes. /var/log/stunnel.log says -> date : stunnel 4.05 on i386-red hat .... with openssl 0.9.7a ->date : FD_SETSIZE=1024 file ulimt=1024 -> 500 clients allowed any input for my problem. It's kinda important. I'm really fed up with the tutorials which shows it works and everything always fails at my place :( greetz christof

converting old syntax to 4.x syntax
by christof mestdag 17 Mar '06

17 Mar '06

Hi, i've got a old syntax and i don't find what the new syntax might be. stunnel -c -d localhost:389 -r win2003server:636 ( I want to make a tunnel to the ssl port of the active directory server to allow password changes ) i've read a possibility which allows no use of certificates but it was in old syntax. any input to change that syntax? i thought it might be something like this. -> client=yes foreground=no accept = 389 connect = win2003server.FME.local what do i do with this. an upgrade manual speaks of an stunnel.conf file. But this one doesn't excists on my Red Hat Desktop computer. It says also that we have an /usr/local/etc/stunnel dir but i don't have that also. I only have an /etc/stunnel dir (which is totally empty ) and the /usr/sbin/stunnel tool ( version 4.05 ) thx in advance

Multiple Host Certificates
by Sligar, Benjamin 17 Mar '06

17 Mar '06

Is it possible to run one instance of stunnel and have it verify certain ports against different certificates? For instance: [listen1 5003] accept = 5003 connect = 10.61.0.132:7300 [listen2 5008] accept = 5008 connect = 10.61.0.132:7300 Would it be possible to have listen2 validate on a seperate certificate, or, will I need to run a second instance of stunnel on my box and have it point to the different certificate? Basically, I want to know if I can setup a different certificate on a per-port basis. I don't see any options in the definition of the listen port that I can specify a different CERT, only the default CERT option at the top of the config file. Version: stunnel-4.04 Options cert = /usr/local/conf/ssl.pem chroot = /usr/local/stunnel-4.04/var/run/stunnel/ pid = /stunnel.pid setuid = www setgid = webgroup options = NO_SSLv2 ciphers = DES-CBC3-SHA:IDEA-CBC-SHA:RC4-SHA:RC4-MD5:AES256-SHA:AES128-SHA uname -a Linux ssl 2.4.7-10 #1 Thu Sep 6 17:27:27 EDT 2001 i686 unknown gcc -v Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98) openssl version OpenSSL 0.9.6b [engine] 9 Jul 2001 This e-mail message is for the sole use of the intended recipient(s) and may contain confidential and privileged information of Transaction Network Services.

Help with config of stunnel.
by mike smith 16 Mar '06

16 Mar '06

I am trying to set up a tunnel for telnet. I am doing this just to learn how to get stunnel to work. I thought this would be easy way to learn how to use stunnel for other uses we have. My problem is I don't understand how to start it on the client side. I can telnet to the server without stunnel but I don't know how to start stunnel on the client side. The log file shows ssltelnet bound to 0.0.0.0:23 for the client and ssltelnet bound to 0.0.0.0:992 for the server If you have any ideas what I may need to do I would be greatfull. I'm sure that I'm missing a step configuring it. This is what my stunnel.conf files look like for the server cert = /usr/local/etc/stunnel/stunnel.pem chroot = /usr/local/var/run/stunnel/ pid = /stunnel.pid setuid = nobody setgid = nobody client = no debug = 7 output = /stunnel.log [ssltelnet] accept = 992 connect = 23 For the Client cert = /usr/local/etc/stunnel/stunnel.pem chroot = /usr/local/var/run/stunnel/ pid = /stunnel.pid setuid = nobody setgid = nobody client = yes debug = 7 output = /stunnel.log [ssltelnet] accept = 23 connect = 192.168.1.102:992 --------------------------------- Yahoo!

IE tries to verify client certificate?
by Don Werve 15 Mar '06

15 Mar '06

I've got stunnel providing SSL wrapper services for an otherwise SSL-stupid vendor-webserver-thingy that listens on port 80. I'm using a wildcard certificate purchased from $VENDOR, and it seems to work fine in Safari, Firefox, w3m, and basically everything SSL aware known to Man. Except, that is, Internet Explorer, where the user gets a popup window asking them to choose a certificate to verify their connection. This is really throwing me for a loop; I've tried setting 'verify = 0' and 'options = ALL' in the service definition under stunnel, no dice. Any ideas why IE thinks it needs to verify, but nothing else does? -- Don Werve <donw(a)iradeon.net> Chief Systems Administrator / Systems Architect

GeoTrust QuickSSL cert and stunnel
by Steve Shepherd 15 Mar '06

15 Mar '06

I've got a client that has a GeoTrust "QuickSSL" certificate (we normally deal with Thawte). I installed the cert/key, but it is not functioning (pulling up default certificate), so I figured I would need the CA. I gathered the CA, so in the file I have: Certificate Private Key Certificate GeoTrust CA Where is the default location to install other CA's and/or chained certs? Thanks!
