Multiple Domains for https
by Thomas Manson 23 Feb '12

23 Feb '12

Hi, I want to setup the following architecture : stunnel ---> haproxy --> 2 webserver. I run severa virtual host on the 2 webservers, and a subset of them needs https. I can allocate several IP address for the host that run stunnel. How do I configure a single stunnel process to have a certificate per IP for the port https? I tryed to add several section like the following : [mansonthomas.com] cert = /etc/stunnel/sites/mansonthomas.com/mansonthomas.com.crt accept = 88.190.17.222:443 connect = 127.0.0.1:82 xforwardedfor = yes TIMEOUTclose = 0 So the question is : Is it possible ? do you have a sample configuration file to share for this use case? Thanks, Thomas.

:o( Stunnel KO on Windows Server 2003 VM
by BOXI31 TEST 22 Feb '12

22 Feb '12

Hi all ! I'm new with Stunnel. It'a nice tool that works perfectly on Windows 7 64-bit host but won't start on Windows Server 2003 guest VM (VMWare Player 3.1.x). When I try to start it, I have a message like "can't initialize...". I'll give you the exact message tomorrow, I don't have now the VM on hand. On Windows 7, when I started Stunnel for the 1st time, I was asked to create a certificate with a kind of wizard but on the Windows Server 2003 VM, it stops before this step. Is it a known problem on VM ? What could I check ? I managed to make the software I'm testing (SMTP sending function) on the VM "talk" to Stunnel on my host by I'd really like to install it on the VM to be independant from host. Thanks by advance, Regards, Steve.

Stunnel Not supporting DSA key
by Anand Krishnan 16 Feb '12

16 Feb '12

Hi All, I have query regarding Stunnel (version 4) working. We have a windows client application which communicates with a web service via SSL encryption with DSA algorithm. The windows client machine is using a pfx file for authentication with server. Now we need to convert this windows machine with a linux machine and hence we converted the pfx into pem file. But when i tried to start the Stunnel using this pem file it threws up below error. 2012.02.13 18:23:23 LOG3[23972:47049761923264]: error stack: 140B3009 : error:140B3009:SSL routines:SSL_CTX_use_RSAPrivateKey_file:PEM lib 2012.02.13 18:23:23 LOG3[23972:47049761923264]: SSL_CTX_use_RSAPrivateKey_file: 607907F: error:0607907F:digital envelope routines:EVP_PKEY_get1_RSA:expecting an rsa key It seems the .pem file I mapped in the stunnel.conf is expecting RSA algorithm but when I opened it I can see it as DSA coded. Can some body help me on this. I am attaching the pfx and pem file along with this.

Key files across NFS
by James Devine 15 Feb '12

15 Feb '12

I have an stunnel config saved on an NFS mount so it can be shared with other servers, it only seems to work if the key file is stored locally, as soon as I move the key onto the NFS mount I get the error: /disks/disk1/stunnel/certs/wildcard.key: Value too large for defined data type (75) Any idea why that might be and what I might do to fix it?

Improving SSL security and protecting against the BEAST attack
by Shannon Carver 06 Feb '12

06 Feb '12

Hi all, Long time lurker, but first time poster on the Stunnel mailing list. I'm currently entering into a business partnership with a prominent media group, and as such they've got some strict guidelines by which their partners should abide by when it comes to Security/Encryption, both for brand protection, and making sure that both sides are sufficiently covered (at least from a general scan point of view). Basically the big thing that is coming up in my testing now (predominantly using the Qualysis tool at www.ssllabs.com) is that I'm vulnerable to the BEAST attack, CBC-Mode vulnerabilities and a potential issue of DoS attack due to server accepting Client Side Re-negotiation. I've spent days now trawling the web looking for a solution, but haven't really found anything of use yet, short of disabling CBC Ciphers completely (e.g 'cipher = RC4-SHA:RC4-MD5:!SSLv2:!ADH:!EDH:!EXP:!aNULL:!eNULL:!NULL' or similar), but I fear this me be too restrictive when it comes to client support. I guess my question is, are there other stunnel users who've been in the same situation, and is there a recommended cipher/options list when using Stunnel for HTTPS? Thanks in advance Shannon

No SSL handshake between stunnel in client mode and SSL server
by Denis Berezhnoy 01 Feb '12

01 Feb '12

Hi guys, I have a quick question. I am trying to use stunnel in client mode to encrypt traffic going to my server. Basically, I have a server which listens for SSL connection. And I have a client which can not do SSL but it needs to communicate with server over SSL. I setup stunnel in client mode to accept unecrypted traffic from client and redirect it to server over SSL. I checked TCP traffic with WireShark between stunnel and my server and I can see that there is no SSL handshake, stunnel makes TCP connection with server and sends some TCP packets but I expect to see SSL handshake. My stunnel conf file is here: [Router] client=yes accept = 192.168.1.121:55555 connect = 192.168.160.168:55443 Can you please comment on this? Best regards, Denis

Possible use-after-free in stunnel 4.52
by David Shaw 01 Feb '12

01 Feb '12

Hello, I am using stunnel 4.52 in client mode with exec and connect. The client program that stunnel execs periodically exits, and is properly re-started by stunnel, as I have "retry = yes" set. However, after a retry, I occasionally get a segfault inside one of the OpenSSL libraries. It does not happen right away, but once it happens, every retry causes the same segfault. I did some debugging and it seems that what is happening during a retry is that the SSL connection is brought down in client_run(), then is freed via SSL_free(c->ssl). However, it seems that c->ssl is used after this free, for example in connect_local(), which calls SSL_get_peer_certificate(c->ssl). When exec, connect, and retry are all set, client_main() will call connect_local() after client_run() exits. This patch seems to resolve the issue: --- client.c.orig 2012-01-11 10:43:33.000000000 -0500 +++ client.c 2012-01-31 18:02:19.155213010 -0500 @@ -162,6 +162,7 @@ if(c->ssl) { /* SSL initialized */ SSL_set_shutdown(c->ssl, SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN); SSL_free(c->ssl); + c->ssl=NULL; ERR_remove_state(0); } For completeness, here's my stunnel.conf: client = yes sslVersion = SSLv3 pid = /var/run/stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 foreground=yes [experiment] connect = x.x.x.x:443 exec = testprog retry = yes David

stunnel and connection alerts for Windows
by John A. Wallace 31 Jan '12

31 Jan '12

Hello. It would be helpful to me to see a little popup window notification of connections or data transfers made through Stunnel, a small and unobtrusive alert of such kind as not requiring me to open another Window, etc.. One thought I have along these lines is to have the stunnel Log Window to serve this purpose by having a configuration option for it to open in a small window by the system alert toolbar on the bottom right, providing a one-liner or abbreviated rendition of its current logging text. I do not know of a way to make this happen within stunnel itself, but if there is functionality of this sort already available, please advise. Another program that comes to mind with this sort of purpose would be Growl, which allows developers to make plugins to create this effect. http://www.growlforwindows.com/gfw/apps.aspx. Is there anyone else here who would find this useful or who is aware of work along these lines? Thanks. John

stunnel and local proxies
by John A. Wallace 30 Jan '12

30 Jan '12

Hello. At times I would like to have Stunnel (in Windows OS) running through a proxy on localhost, say, a socks proxy. Based on what I have seen and read here and in the list archives about that, although admittedly I have not yet read every single thread, I am inclined to say that it is not designed to do so easily if at all. Someone even suggested to me that these settings alone would allow running it over a socks proxy on my machine: ; these settings relate to using stunnel through a proxy ;protocol=connect ;protocolHost=127.0.0.1:portXYZ I tested this on my system but it failed to work. On the other hand I have had success using a program like socat for this purpose. Am I correct in thinking that the above settings alone are not going to do it or do I need additional settings with them for this purpose, or is it not going to work with Stunnel alone? Thanks.

patch for using stunnel as client with pkcs11-engine and opensc smartcard

Dear stunnel managers, I would like to inform you that there exist some incompatibility with stunnel and openssl pkcs11-engine with external PIN entry device (like RSA smartcard using opensc) in Linux.

STunnel on Windows (2008R2 Server)
by Skinner, Robert 28 Jan '12

28 Jan '12

I am attempting to use stunnel to encrypt traffic between our backup client (Window2008R2) and our NetApp filer, but I'm not having any luck We would like to use the stunnel to redirect the port 80 calls to the filer (ubfs2.buffalo.edu) to port 443. Be design, the backup client (IBM Tivoli/TSM V6.2.4) makes a call to the Netapp over http.admin interface to tell it to create a snapshot.

stunnel and socat
by John A. Wallace 26 Jan '12

26 Jan '12

Hello. I use socat to connect stunnel to a socks proxy on my client workstation running windows. the socks proxy then connects to a news server on the internet. The initial connection works just fine and it appears to stay connected while I am transferring data and for a while afterwards; but after a period of idle connection say five or ten minutes, I get a message from my network adaptor popup saying that the connection stunnel had to my localhost has failed. Any ideas on how I can make the connection between stunnel and localhost persist longer during periods of inactivity? I would like it to stay connected until I purposely stop it. Below is the relevant section of "stunnel.conf". [newsreader_to_newsserver] accept = 127.0.0.1:120 connect = 127.0.0.1:5630 CAfile = peer-news_certificate.pem verify = 3

certificate authentications
by John A. Wallace 21 Jan '12

21 Jan '12

I have two questions, which I think may be related, regarding how to use the information from stunnel log. I use stunnel to connect to an SMTP server on the internet from my home network, and in particular from my Windows laptop. My stunnel version is this: stunnel 4.50 on x86-pc-mingw32-gnu platform Compiled/running with OpenSSL 0.9.8r-fips 8 Feb 2011 It works well for my purposes, and I can see, by using a program for monitoring process and network connections, that the connections are now secured as expected. However, I believe it can be made more secure if I can utilize the certificate that is offered by the server, but I am not sure how to make that happen. In my stunnel log for the connection, I get this message: Client-mode smtp protocol negotiations started Client-mode smtp protocol negotiations succeeded No peer certificate received SSL connected: new session negotiated Negotiated ciphers: ADH-AES256-SHA SSLv3 Kx=DH Au=None Enc=AES(256) Mac=SHA1 My first question is, how should I go about getting that "No peer certificate received" issue corrected and how do I install it? Secondly, when I issue this command at the cmd shell prompt: openssl s_client -starttls smtp -connect host.server:port The output is lengthy and it includes, among other things, clearly what is identified as a certificate. I have been told that this is a good certificate, and one that I should utilize for an authenticated connection. So, my question is, is this the same certificate that I saw referenced in the log as the "peer certificate", and how do I go about putting this certificate where it belongs in my directory? I know how to copy it and save it as a file, but where do I put it and should it have a special name? If someone wants to direct me to the correct instruction for doing this, that would be fine too. I am just looking for some pointers for assistance. Thanks.

I've setup stunnel to tunnel port 25 to a few backend smtp servers, it appears that it only works with starttls, is there a way to make it work if no starttls is issued also?

ver 4.5 VS 4.2: running single process now, how to close when all client apps closed?
by larisa_y 19 Jan '12

19 Jan '12

I have several client applications running on win machine, connecting to the same server, or sometimes to different servers. ver. 4.2 allowed me to do the following: modify .conf file to [my_section] accept=5566 connect 123.22.33.44:5005; then run stunnel.exe; modify .conf file to [my_section] accept=5567 connect 456.22.33.44:5006; then run stunnel.exe. That would start 2 stunnel.exe processes, each one handling its own connection; which were easy to close when each respective client app closed - each one would close the one it started. Now with 4.5 version: the single stunnel.exe process runs and is able to handle all communications perfectly, provided I prepare .conf file for all possible connections in advance, before starting stunnel. The problem I cannot solve easily is how not to leave stunnel running after client logged out of all the applications. Without building something to keep track of "stunnels users" count, how could I do it? Is there some way to switch to multiple instances mode? Please advise.

client side SNI
by yyy 14 Jan '12

14 Jan '12

It looks like server name for client side SNI is defined as name to connect to in connect option. According to RFC, this name must be FQDN. It is the only place where it is defined and server name for SNI cannot be defined outside connect option. Is that right? Server side SNI has some good examples. Searching for "client side SNI" did not yield anything useful. I am trying to run multiple independent services over the same port there is no DNS infrastructure in place, so those server names would be random strings not refering to anything. Both ends would be stunnel. If it is as it seems, it will not work, because defined server name (at client) must be working DNS name (FQDN).

Here is the debug output for the Giganews scenario: 2012.01.12 14:05:01 LOG4[292:3840]: CERT: Verification error: unable to get local issuer certificate 2012.01.12 14:05:01 LOG4[292:3840]: Certificate check failed: depth=1, /C=US/O=GeoTrust Inc./OU=Domain Validated SSL/CN=GeoTrust DV SSL CA 2012.01.12 14:05:01 LOG3[292:3840]: SSL_connect: 14090086: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed And the following is from my stunnel.conf: ~~~~~~~~~~~~~~~~~~~~~~~~~~~ debug = 6 delay = yes [nntps.3] client = yes sslVersion = TLSv1 ciphers = AES256-SHA cafile = peer-nntps.3.pem verify = 3 accept = 127.0.0.1:119 connect = news.giganews.com:443 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ As I have with other connections, I am saving peer-nntps3.pem from the log window menu. Can anyone tell me why this is failing on this server only? Regards; Thomas

fips=no and slow performance problem
by Owen Ching 12 Jan '12

12 Jan '12

I have a production system that uses stunnel and it's been working pretty well. Mike, thanks for all your hard work. But there has been a weird issue that I ran into a while ago and now it's happening again. we're using a rackspace cloud machine to run stunnel and haproxy. we're using the x-forwarded-for stunnel patch for now with plans to upgrade to send-proxy method once haproxy 1.5 is considered the stable branch. So I built one machine and ran into the "FIPS_mode_set: 2D06C06E: error:2D06C06E:FIPS routines:FIPS_mode_set:fingerprint does not match" error message. So I changed the config to fips=no and stunnel started up but the https seems really slow (multiple browsers). We run with significant https volume. So the fips=no option didn't work for us. I kept trying different things but nothing worked. I decided to start clean and built a new machine. This time stunnel didn't throw the FIPS error and everything performed great. So used the new machine instead. Now after some time (over a year), we had some performance problems. we rebooted the machine and now we have the FIPS error again. I've tried multiple versions of stunnel (whatever I could find working patches for) and also tried a clean 4.51 with no patches. all of them throw the FIPS error now on this machine. I'm in the process of building a new machine to see if it magically works again. Any help or insight would be greatly appreciated. Thanks, Owen

I am having problems with the 4.5x-series also: Pan connects, nothing else happens.

Hi, I am also having no luck using the stunnel-4.5* series. The last/latest working for me is 4.49. $ uname -a Darwin SciFi.homeip.net 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386 i386 iMac6,1 Darwin (altho this is a C2D machine, running most tasks in 64-bit mode, Apple has left the EFI/BIOS/kernels at 32-bit… yes I can boot+run 10.7/Lion, but that is a total separate topic altogether [don't get me started]…) I mainly use stunnel with Pan, to connect to Giganews, Astraweb, and Gmane (which is what I'm using now to post this message). I use the simple 127.0.0.1:port mechanism. (I've been working with one of Pan's new developers, to try their new GnuTLS support; but until that works, stunnel is my known supposedly-functioning fallback.) I've tested every 4.5x release, including today's 4.52b1 & b2 -- all act the same, in that Pan tries to connect to stunnel, and that's all I see, nothing further happens. Also, the 4.5-series produces much-less log-listing, as you'll see in my attachments below. I am fine while relegated to using stunnel-4.49, but we have a further issue, in that the "verify=<number>" option seems to reject the certs & what-not coming from these servers, for any <number> higher than 0 (yes I saw the maillist discussion about what 4 means there, and tried it also). I've been mildly joking with the Pan developer on how to be sure we are /really/ in secure mode. ;) Now, the details. I manually start stunnel on a login-root terminal window, this way: # stunnel /usr/local/etc/stunnel/stunnel.conf -sockets With these sample log-lists (below), I'm trying to get one single short post in a newsgroup. I made sure Pan did not save this post in its cache, such that it does try to fetch the post from the NNTP server. (Currently, Pan is set to use Astraweb as my primary feed.) Here's what 4.49 will show on the terminal (this works: I can see the modem blinking, and can see/read the post): ---start--- 2012.01.11 10:24:51 LOG7[3782:2697274688]: Clients allowed=500 2012.01.11

Stunnel 4.33 last one to work with VM & IMAP
by Drew McDermott 11 Jan '12

11 Jan '12

I am running VM 8.1, the Emacs mail reader, connecting via imap to gmail. It can be made to work with stunnel 4.33 providing the encryption, but any version after that causes VM to choke when fetching messages, generating the following error message: vm-imap-protocol-error: IMAP protocol error: "unexpected char (10)" Not being an expert in any of the programs that are chained together to make my e-mail setup work, I was able to trace this no deeper than the point where VM reads the buffer Emacs uses for interprocess communication. Sure enough, there is a linefeed in a place where it isn't expected, but it also happens to be the first character in the sequence: " Process IMAP over SSL finished " which may be there because of problems deeper than the representation of "newline." At the end of this message I give my attempt to represent the complete contents of the buffer with name "trace of IMAP over SSL session to imap.gmail.com." The ^M's were inserted by hand because cutting and pasting didn't seem to reproduce them. I realize that I am providing quite a bit of information from VM, and none from stunnel, which is frustrating in an stunnel forum, but I am a complete newbie regarding stunnel. I would be glad to run further experiments with guidance on how to get stunnel itself to generate more useful information. The only reason I suspect it is that installing version 4.33 fixes the problem; but I realize it may be that VM or some other component is violating the rules somehow. When I say "any version after" 4.33, I mean that I have tried 4.35, the version installed by MacPorts; and 4.49, the latest stable version, recompiled by hand. They behave identically. -- Drew McDermott Professor of Computer Science Yale Computer Science Department The interprocess-communication buffer (everything between the dashes, including the newline after "finished," but not including the newline before "starting"): --------------- starting IMAP over SSL session Tue Nov 29 14:20:01 2011 connecting to imap.gmail.com:993 connected * OK Gimap ready for requests from 128.36.148.241 s17if7011003qao.19 VM CAPABILITY Process IMAP over SSL finished ---------------

Missing bytes?
by Arthur Murray 01 Jan '12

01 Jan '12

Hello, When I telnet to my pop3 server and "QUIT" this is what I see: Escape character is '^]'. +OK InterMail POP3 server ready. QUIT +OK ? InterMail POP3 server signing off. Connection closed by foreign host. When I setup an stunnel 4.5 to the same pop3 server: [pop3s] accept = 995 connect = server:110 and connect with "openssl s_client -connect localhost:995" this is what I see: +OK InterMail POP3 server ready. QUIT DONE And the stunnel log reports: Connection closed: 34 bytes sent to SSL, 0 bytes sent to socket What happened to the last line "+OK ? InterMail POP3 server signing off." and why aren't the counters counting the 5 bytes I sent ("QUIT\n") and the last line of 41 sent over the SSL? Example 2 through stunnel: +OK InterMail POP3 server ready. USER -ERR a user name MUST be entered QUIT DONE Connection closed: 68 bytes sent to SSL, 5 bytes sent to socket (still missing the last bytes)

Re: [stunnel-users] Configuring VeriSign certificate with STunnel

Hi Guys, Thanks for your replies. I tried following commands on verisign c certificate, for both of these do not work. There is error 'unable to load certificate'. openssl x509 -inform DER -in stunnel.pem -noout -text or openssl x509 -inform PEM -in stunnel.pem -noout -text however if I run same command (openssl x509 -inform PEM -in stunnel.pem -noout -text) on VeriSign root & Intermediate certificate it works. It shows format should be 'pem'. But somehow certificate is not valid. I am using following commands to create csr and private key.

I am using stunnel v. 4.41. I am relatively new to stunnel myself. The env. is as follows: We are trying to secure an rdp connection from a java applet running in a web browser into a windows 2008 server machine behind our firewall. Presently, the java applet opens up an RDP connection into a machine (I will call it the SSL machine) where Stunnel is presently installed. Stunnel then forwards properly the incoming traffic (from portA) into its final destination (i.e: the windows Server 2008 machine) on port B. Further, I have configured Stunnel to use an SSL certificate. (Although, I have not been able to test that yet to make sure it works) Anyhow, it is all working as expected and I am pretty happy about the proof of concept. However, while testing it a bit, I noticed that it was relatively easy to bring stunnel down. The way I went about it, was to simply run a "telnet IP_of_MySSLMachine portA" from any DOS command window from any machine with internet access. From the Stunnel logs, I can tell that I get a response from Stunnel and on the DOS window side, I have a cursor waiting for input.... Writing any gibberish into that DOS windows and waiting a little bit makes stunnel stop and die in the SSL machine. I found nothing in the stunnel log, but grepping in the /var/log/, I found the segfault sslmahine:/var/log/# grep stunnel messages kernel: [1996904.624042] stunnel [19696]: segfault at 8 ip b768d361 sp b7601210 error 4 in libc-2.7.so[b7621000+138000] After another telnet execution, few days later: sslmahine:/var/log/# grep stunnel messages kernel: [4930384.164316] stunnel [14540]: segfault at 8 ip b7629b61 error 6 in libc-2.7.so[b75bd000+138000] Basically, if I don't issue that telnet command, stunnel works properly. As soon as I issue that command and start typing few things in that DOS console, stunnel dies. I have to manually restart it. Question: I was wondering if you guys could shed some light into this behavior. Is it a known behavior/bug? Is there a way to solve it by maybe upgrading into a later version of stunnel? Also, I was thinking to block telnet altogether at the firewall level, but then I am not sure what other protocols could people use to hack into the system...so should I block all of them? And, finally is there a more secure way to setup stunnel? Thank you in advance Mehdi/

I am using stunnel v. 4.41. I am relatively new to stunnel myself. The env. is as follows: We are trying to secure an rdp connection from a java applet running in a web browser into a windows 2008 server machine behind our firewall. Presently, the java applet opens up an RDP connection into a machine (I will call it the SSL machine) where Stunnel is presently installed. Stunnel then forwards properly the incoming traffic (from portA) into its final destination (i.e: the windows Server 2008 machine) on port B. Further, I have configured Stunnel to use an SSL certificate. (Although, I have not been able to test that yet to make sure it works) Anyhow, it is all working as expected and I am pretty happy about the proof of concept. However, while testing it a bit, I noticed that it was relatively easy to bring stunnel down. The way I went about it, was to simply run a "telnet IP_of_MySSLMachine portA" from any DOS command window from any machine with internet access. From the Stunnel logs, I can tell that I get a response from Stunnel and on the DOS window side, I have a cursor waiting for input.... Writing any gibberish into that DOS windows and waiting a little bit makes stunnel stop and die in the SSL machine. I found nothing in the stunnel log, but grepping in the /var/log/, I found the segfault sslmahine:/var/log/# grep stunnel messages kernel: [1996904.624042] stunnel [19696]: segfault at 8 ip b768d361 sp b7601210 error 4 in libc-2.7.so[b7621000+138000] After another telnet execution, few days later: sslmahine:/var/log/# grep stunnel messages kernel: [4930384.164316] stunnel [14540]: segfault at 8 ip b7629b61 error 6 in libc-2.7.so[b75bd000+138000] Basically, if I don't issue that telnet command, stunnel works properly. As soon as I issue that command and start typing few things in that DOS console, stunnel dies. I have to manually restart it. Question: I was wondering if you guys could shed some light into this behavior. Is it a known behavior/bug? Is there a way to solve it by maybe upgrading into a later version of stunnel? Also, I was thinking to block telnet altogether at the firewall level, but then I am not sure what other protocols could people use to hack into the system...so should I block all of them? And, finally is there a more secure way to setup stunnel? Thank you in advance Mehdi/

Incompatibility between openssl 1.0.0 and 0.9.8 which cause stunnel windows version malfunction.
by ayanamist 21 Dec '11

21 Dec '11

I generated a pair of key and certificates with openssl 1.0.0d, and use them in stunnel 4.36. Today i upgrade it to stunnel 4.50 and it doesnot work. All configurations remain unmodified. Then i tested many versions and found, stunnel with openssl 1.00 works fine while with openssl 0.98 does not work. I use stunnel with linux server and windows client, stunnel 4.50 windows version is using openssl 0.98, so cause this problem. 4.47 is using 1.00e which i think is newer than 0.98 bundled with 4.50. So why stunnel keep changing openssl version?

Re: [stunnel-users] Configuring VeriSign certificate with STunnel

Hi, Here are steps how I created certificate request and private key. Generate private key openssl genrsa -des3 -out server.key 2048 Generate certificate request openssl req -new -key server.key -out server.csr I submitted server.csr contents to VeriSign to get test certificate and they provided me three certificates. VeriSign signed certificated Root certificate Intermediate certificate I copied VeriSign signed certificate in stunnel.pem and other two certificates in ca.pem file. As per my observation STunnel is unable to load stunnel.pem file. If you need VeriSign test certificate I can provide you that as well. Please let me know if you need further information.

Configuring VeriSign certificate with STunnel
by Zubair Ali Mansoor 21 Dec '11

21 Dec '11

Hi, I got VeriSign Test SSL certificate. I have been trying to configure it with STunnel. But there are errors in STunnel. I have placed private key and CA signed certificate in a separate file named 'stunnel.pem'. Root and Intermediate certificates have been placed in following order in a file named 'ca.pem' stunnel.pem -----BEGIN RSA PRIVATE KEY----- encrypted key -----END RSA PRIVATE KEY----- -----BEGIN CERTIFICATE----- VeriSign signed certificate -----END CERTIFICATE----- ca.pem -----BEGIN CERTIFICATE----- VeriSign Intermediate CA Certificate -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- VeriSign Root CA Certificate -----END CERTIFICATE----- Here is stunnel.conf file. ;key = server.key cert = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ; Authentication stuff verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile CAfile = ca.pem ;CAfile=zosIntermediate.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem ; Some debugging stuff useful for troubleshooting ;debug = 7 output = stunnel.log ; Use it for client mode client = no I have also tried to change order of certificates but nothing is working. Anyone have idea how it can work. Your cooperation will be highly appreciated. Thanks, Zubair
