Squid documentation will tell you what is the need for the home-made authentification program. I think it's easier with DansGuardian proxy : - In stunnel config file : select pertinent fields of the certiificate : only Issuer_CN -> identFields=32 - in /etc/dansguardian/dansguardian.conf, create 2 groups : filtergroups = 2 filtergroupslist = '/etc/dansguardian/lists/filtergroupslist' - create filter groups in /etc/dansguardian/lists/filtergroupslist. (All not matching users will go in group 1) : put a line like "your issuer CN equals 2" - in /etc/dansguardian/dansguardianf1.conf, put "groupmode=0" , ie banned - in /etc/dansguardian/dansguardianf2.conf, put "groupmode=2" , ie non filtered Note that the authentification of the users is done by stunnel. Stunnel forwards the identification to the proxy which does not need to authenticate since it was done by stunnel. If the ident provided by my patch is not convenient, you can modify it to match your needs. Hope this helps -- Christophe Nanteuil

Hi, [...] > But this setup is senseless, since the DN is readable with a network sniffer. > It does not appear harmless any longer after a closer look into the network > traffic.

One easy solution that comes to mind is to deploy an outer SSL tunnel for privacy and then set up an inner SSL tunnel for traffic separation. However, I think this would require stunnel on the client side as well, at least for legitimate users. Cheers, Toby. -- begin LOVE-LETTER-FOR-YOU.txt.vbs I am a signature virus.

Stunnel (v4.26) Running, Working, but Sometimes Aborting
by Jeff Salisbury 09 Jan '09

09 Jan '09

Greetings, We are new to stunnel. We've installed Stunnel v4.26 on a handful of Windows XP machines, and we can send and receive emails through the Stunnel configuration. These XP machines reboot automatically every night. Many mornings, when the user sits down and tries to initially send email, the email hangs and Stunnel aborts (or has already aborted). If the user runs stunnel again, our sending and receiving of email is restored and stunnel seems rock-solid for the rest of the day. Has anybody else had stability problems with Stunnel v4.26? Any suggestions? FYI, relevant configuration information is shown below: Best regards, Jeff ================================== 1) Instead of installing stunnel on each machine, we have copied the following files into a network folder available to everyone in our office: Q:\bin\stunnel\stunnel.exe Q:\bin\stunnel\Q:\ibeay32.dll Q:\bin\stunnel\libssl32.dll Q:\bin\stunnel\stunnel.conf 2) Everyone has a shortcut installed in their "Startup" folder to run Q:\bin\stunnel\stunnel.exe. 3) Here is our stunnel.conf file: # GLOBAL OPTIONS client = yes output = C:\Documents and Settings\All Users\Application Data\stunnel-log.txt debug = 0 taskbar = yes # SERVICE-LEVEL OPTIONS [pop3] accept=995 connect=mail.ourpop.com:995 [smtp] accept=465 connect=mail.oursmtp.com:465

Distinguished Name (DN) is a cleartext network communication?
by Michael Renner 07 Jan '09

07 Jan '09

Moin, I am confused. Trying to use the DN as a kind of password replacement I saw that the DN goes unencrypted through the network, while the traffic itself is encrypted of cause. Analysing the network packages with wireshark I get this: 100104083828Z0..1.0...U....DE1.0...U....Germany1.0 ..U....Munich1.0...U. ..vbox4php1.0...U....stunnel1.0...U....mars.mtr.mynet1$0"..*.H.. .....michael.renner(a)gmx.de0.."0 This is, more or less, the content of the DN. Is there a chance to encrypt this? My setup should work, no matter if a client certificate exists or not (also independent of the DN's content) . But the appliation behind stunnel (started by stunnel using the 'exec' statement) may behave dependent on the DN! Any chance?

Stunnel New User
by David Aitchison 07 Jan '09

07 Jan '09

Hello, I have a potential use for Stunnel on a project I am working on. Excuse the perhaps very silly questions, this is all new to me. I have read through the manual, and understand that Stunnel can either be run from the command line ad-hoc or as an application using the stunnel.conf configuration file. If I have Stunnel running on the server, does this mean that all mails that leave that server will be SSL encrypted? I have a requirement to send mails out over SSL, but my application doesn't support that, it does support sending out over standard SMTP port 25, but I need it to use port 465? Thanks in advance, David Aitchison

hiding a proxy that appear like a web server?
by Michael Renner 03 Jan '09

03 Jan '09

Moin, I want to use stunnel (in conjunction with prtunnel) to reach my own proxy server out of a restricted network. The normal stunnel connection works so far without a problem. But I am looking for a possibility that this connection (reaching the endpoint of stunnel with my proxy server behind) appears like a normal webserver (maybe with just one simple index.html) to others. Any ideas? Thanks -- |Michael Renner E-mail: michael.renner(a)gmx.de | |D-81541 Munich Germany ICQ: #112280325 | |Germany Don't drink as root! ESC:wq

Problem with the client certificate
by Michael Renner 27 Dec '08

27 Dec '08

Moin, it seems that I understood something wrong with stunnel client certificates. First of all: until now I run stunnel 4.18 and stunnel 4.21 with debian and kubuntu without client certificates (with success). I use it to reach a proprietary application through an untrusted network. Now, I want the clients to authenticate against the server. Therefor, as a quick and dirty test, I used the same stunnel.pem file at the server and at the client side. The configuration at the server side (where the application is waiting for connections, in this example it is just a script) looks like this: cert = /etc/stunnel/stunnel.pem #chroot = /var/run/stunnel/ pid = /tmp/stunnel.pid setuid = nobody setgid = nogroup output = /var/log/stunnel4.log exec = /root/stest.sh verify = 1 [BreakOut] accept = 192.168.0.1:443 Here is the configuration at the client side, where a browser establish a connection cert = /etc/stunnel/stunnel.pem key = /etc/stunnel/stunnel.pem sslVersion = SSLv3 chroot = /var/lib/stunnel4/ setuid = stunnel4 setgid = stunnel4 pid = /stunnel4.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 verify = 0 debug = 7 output = /var/log/stunnel4/stunnel.log client = yes [BreakOut] accept = 127.0.0.1:8080 connect = 192.168.0.1:443 First of all: is it right to set 'verify = 1' at the server side, and 'verify = 0' at the client side? It seems right to me, because the client should authenticate, but not the other way. Anyhow: As soon as a connection is opened using this configuration it will terminate at the same second. renner@mars:~$ telnet localhost 8080 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host.

In my first tests I used one that I made with tinyCA, an other was made according http://www.stunnel.org/faq/certs.html: * openssl req -new -x509 -days 365 -nodes -out stunnel.pem -keyout stunnel.pem * openssl gendh 512 >> stunnel.pem * openssl rsa -in stunnel.pem -out new.pem * edit new.pem, merge some parts with stunnel.pem and rename it Any hint?

Windows binary kits on 64 bit 2003 server or 2008 server
by Rich Jordan 24 Dec '08

24 Dec '08

Sorry to sully the list with wintel questions, but I haven't been able to locate an answer, and without systems available to test the obvious method of finding out is not available. We're running Stunnel V4.26 on a windows 2003 32-bit server, communicating with several better platforms running Stunnel V4.20 and newer, no issues. One interested customer is running windows 2003 server, 64-bit, and plans on moving to win2008 server 64 bit in the not too distant future. I do not have access to either OS/system and they're reluctant to install without knowing ahead of time what might happen. I'm hoping someone has tried the current STunnel binary kit on either or both of those systems. Will the kit run on 64-bit windows 2003, and is it usable on windows 2008? If not is this a situation where a build from source on either/both of those windows systems will produce working code? I've also found a number of hits for reputed OpenSSL ports for 64 bit windows. Any particular ones known to be good? Thanks for any info. Rich Illuc ivi, illud feci
