Intermediate Cert validation problem
by Eric McCombs 31 Jan '07

31 Jan '07

I'm experiencing a problem validating intermediate cert on our Stunnel configuration. We are using Stunnel to forward IMAP, POP and SMTP SSL ports from our vpn server to our internal mail server. We originally used a self-signed cert on the vpn server. When clients connect via Outlook, Outlook Express, Thunderbird and various cell phone mail programs they received a warning message (Unable to verify identity of xxx) about the self-signed cert. To resolve this issue we purchased a SSL cert from Verisign to install on the vpn server. We generated the key and CSR and received the new cert from Verisign, which also requires an intermediate cert for verification. We have tried various methods to have the certs validated, combining the key, intermediate cert and server cert in one file, pointing to the CA_file, etc. but continue to see the Unable to verify identity message. Has anybody else encountered this problem and found a way to resolve the problem? Thanks in advance. Eric McCombs

To all, Can Stunnel communicate bi-directionally over a single port? Or does it listen on one and communicate on a different one? Thanks Dean

Re: [stunnel-users] How is stunnel started ? / Searching stunnel service name
by Ben Stover 22 Jan '07

22 Jan '07

Hmm that is very curious. I investigated now all runnig services and did not found the stunnel service. The only reason I can find for this is that the service name does not contain "stunnel" in its name. How is it called otherwise? My services here (under Win2000) are (when I type "net start" at the command prompt): Alerter AVK Monitor AVK Service AVKProxy COM+ Event System Computer Browser DHCP Client Distributed Link Tracking Client Event Log IPSEC Policy Agent Logical Disk Manager MGABGEXE Network Connections PDFCreatorMessages PDScheduler Plug and Play Print Spooler Protected Storage Remote Access Connection Manager Remote Procedure Call (RPC) Remote Registry Service Removable Storage RunAs Service Security Accounts Manager Server Still Image Service System Event Notification Task Scheduler TCP/IP NetBIOS Helper Service Telephony Washer AutoComplete Windows Management Instrumentation Windows Management Instrumentation Driver Extensions Workstation Is it IPSEC Policy agent the service for stunnel ?

Error I am receiving in stunnel logfile (help please!)

Hello Everyone, I tried it on 4.3.3 as well with my re-compiled version ... below are all 5 lines in the log file. stunnel 4.16 on powerpc-ibm-aix4.3.3.0 with OpenSSL 0.9.8c 05 Sep 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv4 stunnel connected from 127.0.0.1:37690 remote socket: Addr family not supported by protocol (66) Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket I also recompiled the latest stunnel with and without IPv6 ... same result with IPv6 as with IPv4 and same result with the new version: stunnel 4.20 on powerpc-ibm-aix4.3.3.0 with OpenSSL 0.9.8c 05 Sep 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 stunnel accepted connection from ::ffff:127.0.0.1:59274 remote socket: Addr family not supported by protocol (66) Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket I have been using this for a while but I had to transfer to a new machine (AIX 4.3 to 5.3) and had to recompile my software and get a newer stunnel. I am now on 4.20 I thought it might be related to ipv4 versus ipv6 ... according to AIX documentation I had it set up for ipv4. I tried ipv6 for ducks, no difference. My inetd.conf line is: visanet stream tcp nowait root /visanet/ssl/stunnel stunnel visanet stream tcp6 nowait root /visanet/ssl/stunnel stunnel The second is IPv6. The error is somehow on the remote though. I can connect to the remote with telnet ... just not stunnel. It seems that depending on how inetd is configured, stunnel accepts either the IPv4 or IPv6 whether or not I compil it using USE_IPv6 1 or not ... what am I missing!? I really only need to hack it to connect to this one site, at least for the moment. /visanet/ssl/visanet.conf My .conf file is: output = /tmp/stunnel.log debug = 5 RNDfile = /visanet/ssl/stunnel.rnd RNDoverwrite = yes client = yes connect = ssllab.pgs.wcom.net:443 sslVersion = SSLv2 cert = /visanet/ssl/stunnel.pem EGD = /etc/egd-pool My guess is that this is something really stupid I am doing, but it is not obvious.

RE: [stunnel-users] Does editing *.conf file require restart of stunnel ?

Hi, As far as I know the service needs to be restarted to load the new configuration. Regards Craig -----Original Message----- From: stunnel-users-bounces(a)mirt.net [mailto:[email protected]] On Behalf Of Ben Stover Sent: 15 January 2007 01:16 PM To: stunnel-users(a)mirt.net Subject: [stunnel-users] Does editing *.conf file require restart of stunnel ? Hello, sorry for this newbie question. I did not found the answer in the FAQ. Assume I edit the *.conf file. Is it required to restrat stunnel (service) to enable the changes ? Or is the *.conf file read at ever new stunnel call? If explicit restart is required: would it be possible to add a context menu entry to the Windows systray-Stunnel-icon "restart". This would make handling much more comfortable than always opening a command line window and entering all the commands manually.

Sorry David that I have misted you e-mail. I'm using stunnel on a Windows server and I have working it all. I use outlook express as mail client and when I pres OK on the message of the certificate it works. But I want to install a real certificate. Only I don't exactly where I have place which part of the certificate and what I place into the stunnel.conf I have a part I sent to CA created whit openssl req -new -days 365 -nodes -config stunnel.cnf -out certreq.pem -keyout stunnel.pem I have get return a file certnew.cer and I have the file stunnel.pem. And now I don't know what I have to do next to get this certificate. I have tried several options but no one works.

I'm curious if anyone else has tried Stunnel with Powerposter on the Giganews Usenet network. I (and many other users) have reported problems whereby the post does not complete and just hangs. Per Giganews, this is a software problem and not their servers. Non-SSL posting in Powerposter works fine. but hangs when Stunnel is used usually after a couple of files are successfully uploaded. Any else run into this? TIA! Roger

I tried sending directly to you, I must have looked like a spammer. I am ever so slightly pleased to see that I have some company in my frustration with this software. I'll try to help, since the experts seem to be too busy. I've only used it twice, and it was painful both times. Have you gotten it to work at all? That is, what do you see? Do you get a running stunnel process? Do you have (with permissions) ls -l /usr/local/etc/stunnel/mail.pem -rw------- 1 root staff 2233 Jan 5 17:25 /usr/local/etc/stunnel/ mail.pem I created it by running this command in that directory: sudo openssl req -new -out mail.pem -keyout mail.pem -nodes -x509 - days 365 I created a stupid certificate, because at some point it looked like it was asking me for my name (David Chase) when what they wanted was my fully qualified domain name (dr2chase.org), so that part of the certificate is wrong. The certificate creation in the makefile asked for this in a slightly more sensible way, using the abbreviation "FQDN", though you have to wonder how busy the authors of some of this security software are, that they cannot take the time to type in "Fully qualified domain name", and instead expect us to figure it out. It can be whiny about permissions, in a non-specific way (as if the software ran a one-way-hash on the permissions, didn't get a match, and expected you to just guess till it worked.) sudo chmod 600 /usr/local/etc/stunnel/mail.pem sudo chmod 755 /usr/local/etc/stunnel/ sudo chown root /usr/local/etc/stunnel/stunnel.conf You'll need to copy the sample stunnel.conf file into the real one: sudo cp /usr/local/etc/stunnel/stunnel.conf-sample /usr/local/etc/ stunnel/stunnel.conf You might want to look it over, though I don't recall changing much in mine. You might want to turn on debug logging there; mine seemed to spew in the invoking terminal, instead of any file that I could find, but that was good enough for a start: debug = 7 output = stunnel.log Some part of stunnel created its chroot directory with incorrect (for MacOS, at least) permissions: % ls -ld /usr/local/var/lib/stunnel/ 948 drwxrwx--T 2 root wheel 68 Jan 5 16:55 /usr/local/var/lib/ stunnel/ That's the one that didn't work, and clearly someone thought carefully about giving it the wrong permissions -- that "T" didn't get there accidentally. This caused silent failure for me. What worked, but might not be secure, is drwxrwxrwx 2 root wheel 68 Jan 6 00:16 /usr/local/var/lib/stunnel/ My guess is that it would be better if it were owned by nobody/nogroup, but this is clearly something that trained experts should GET RIGHT, instead of leaving it busted for novices to tinker with. What mail reader are you using? For example, Apple Mail's "connection doctor" will treat an unofficial certificate as a connection failure; only when you actually try to receive or send mail, will you get a chance to trust the certificate. Perhaps my sarcastic remarks will cause someone to actually fix something. Who knows. yours, David Chase

STunnel not creating connections.
by Paul Morrison 09 Jan '07

09 Jan '07

I have a problem perhaps someone can help me with. I have setup Stunnel and OpenSSL on a Windows 2003 server. It is configured to accept data on TCP port 2000, decrypt it, then pass it on to TCP port 8014. I have placed the certificates provided for this in a directory and I have told STunnel where these certificates are. The problem I am having is I can see the connection from port 2000 coming in to the system, but STunnel then does nothing before finally dropping the connection. The version of STunnel and OpenSSL are (stunnel 4.15 on x86-pc-mingw32-gnu with OpenSSL 0.9.7i 14 Oct 2005) I have the same setup at a different site on a different server and it works fine. In the debug.log the following is output: 2007.01.09 13:41:02 LOG7[684:352]: MATSU_GPRS started 2007.01.09 13:41:02 LOG7[684:352]: FD 196 in non-blocking mode 2007.01.09 13:41:02 LOG5[684:352]: MATSU_GPRS connected from 212.183.136.192:57511 2007.01.09 13:41:02 LOG7[684:352]: SSL state (accept): before/accept initialization 2007.01.09 13:41:22 LOG3[684:352]: SSL_accept: Peer suddenly disconnected 2007.01.09 13:41:22 LOG5[684:352]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2007.01.09 13:41:22 LOG7[684:352]: MATSU_GPRS finished (0 left) I would normally expect to see details of the SSL connection and the certificates being checked after the line 2007.01.09 13:41:02 LOG7[684:352]: SSL state (accept): before/accept initialization, but as you can see it does nothing before dropping the connection after 20 seconds. Does anyone know why this installation of STunnel does not seem to be attempting to use the certificates provided? I would be very grateful for any advice. P.S. Do I need to have a Certifcate Authority server setup at the site in order for STunnel to work?

I figured it out. The webserver was redirecting me to the index.html page so that is where the protocol was getting changed. So now the question changes. Is there a function in stunnel for URL rewriting? In otherwords the webserver sends back "redirect yourself to http:// but stunnel intercepts that before it gets back to your browser to keep the connection secure?

Hi, I noticed that stunnel already does round-robin load balancing of connections when the DNS name specified by the "connect" option resolves to multiple IP addresses. Here is a simple patch which allows the "connect" option to accept a comma separated list of names instead of just a single name. This can be used to load balance tunnelled connections across several servers. For example, to load balance HTTPS connections across 3 HTTP servers (localhost:80, anotherhost:8080 and anotherhost:8081), we could specify: [https] accept = 443 connect = 80,anotherhost:8080,anotherhost:8081 Regards, Luke. ********************************************************************************************** Important Note This email (including any attachments) contains information which is confidential and may be subject to legal privilege.

Foolishly, I trusted it to create /usr/local/var/lib/stunnel/ with the correct permissions. The directory that appeared had these permissions: ls -ld /usr/local/var/lib/stunnel/ drwxrwx--T 2 root wheel 68 Jan 5 16:55 /usr/local/var/lib/stunnel/ When I replaced it with this directory ls -ld /usr/local/var/lib/stunnel/ drwxrwxrwx 3 root wheel 102 Jan 5 20:43 /usr/local/var/lib/stunnel/ Suddenly, when I ran stunnel, it continued to run. I'd call this a bug. Still not doing quite what I want, (not connecting to elsewhere.com like I expect) but I'm closer. David Chase

But I think the documentation has some serious gaps in it, too. I compiled stunnel, installed it, created certificates, and even turned on debugging in the configuration file. Now, all I want to do is forward port 443 locally to port 80 elsewhere. Says my config file: cert = /usr/local/etc/stunnel/mail.pem ;key = /usr/local/etc/stunnel/mail.pem ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = SSLv3 ; Some security enhancements for UNIX systems - comment them out on Win32 chroot = /usr/local/var/lib/stunnel/ setuid = nobody setgid = nogroup ; PID is created inside chroot jail pid = /stunnel.pid ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log ; Use it for client mode ; client = yes ; Service-level configuration [pop3s] accept = 995 connect = 110 [imaps] accept = 993 connect = 143 [ssmtp] accept = 465 connect = 25 [https] accept = 443 connect = elsewhere.com:80 TIMEOUTclose = 0 and when I run it, it says: sudo /usr/local/sbin/stunnel Password: 2007.01.05 18:51:01 LOG7[13470:2684415368]: Snagged 64 random bytes from /Users/chase/.rnd 2007.01.05 18:51:01 LOG7[13470:2684415368]: Wrote 1024 new random bytes to /Users/chase/.rnd 2007.01.05 18:51:01 LOG7[13470:2684415368]: RAND_status claims sufficient entropy for the PRNG 2007.01.05 18:51:01 LOG7[13470:2684415368]: PRNG seeded successfully 2007.01.05 18:51:01 LOG7[13470:2684415368]: Certificate: /usr/local/ etc/stunnel/mail.pem 2007.01.05 18:51:01 LOG7[13470:2684415368]: Certificate loaded 2007.01.05 18:51:01 LOG7[13470:2684415368]: Key file: /usr/local/etc/ stunnel/mail.pem 2007.01.05 18:51:01 LOG7[13470:2684415368]: Private key loaded 2007.01.05 18:51:01 LOG7[13470:2684415368]: SSL context initialized for service pop3s 2007.01.05 18:51:01 LOG7[13470:2684415368]: Certificate: /usr/local/ etc/stunnel/mail.pem 2007.01.05 18:51:01 LOG7[13470:2684415368]: Certificate loaded 2007.01.05 18:51:01 LOG7[13470:2684415368]: Key file: /usr/local/etc/ stunnel/mail.pem 2007.01.05 18:51:01 LOG7[13470:2684415368]: Private key loaded 2007.01.05 18:51:01 LOG7[13470:2684415368]: SSL context initialized for service imaps 2007.01.05 18:51:01 LOG7[13470:2684415368]: Certificate: /usr/local/ etc/stunnel/mail.pem 2007.01.05 18:51:01 LOG7[13470:2684415368]: Certificate loaded 2007.01.05 18:51:01 LOG7[13470:2684415368]: Key file: /usr/local/etc/ stunnel/mail.pem 2007.01.05 18:51:01 LOG7[13470:2684415368]: Private key loaded 2007.01.05 18:51:01 LOG7[13470:2684415368]: SSL context initialized for service ssmtp 2007.01.05 18:51:01 LOG7[13470:2684415368]: Certificate: /usr/local/ etc/stunnel/mail.pem 2007.01.05 18:51:01 LOG7[13470:2684415368]: Certificate loaded 2007.01.05 18:51:01 LOG7[13470:2684415368]: Key file: /usr/local/etc/ stunnel/mail.pem 2007.01.05 18:51:01 LOG7[13470:2684415368]: Private key loaded 2007.01.05 18:51:01 LOG7[13470:2684415368]: SSL context initialized for service https I see nothing that looks like a complaint, but when I go looking for a stunnel process, there is not one, nor is anyone listening on port 443 at localhost. I cannot be the first person who wanted to do this, but I found both the FAQ and the documentation to be uninformative. How do I keep stunnel running and listening for connections on 443? I tried client=yes, that didn't seem to help. I am running Stunnel 4.20 on MacOS 10.4.8 David Chase
