RE: Stunnel Forks Out of Control

Hi all, Ok, I've gone through my last log file for when this issue happens. There's "1130 finished (2 left)" (where 1030 is the port we're listening on) at 10:22am, for example. Then, the next "1130 finished" doesn't happen for about another 20 minutes (which is weird), and then says, "1131 finished (124 left)". It's at this point that a lot of "connection reset by peer"'s happen and "0 bytes sent to SSL" also happen. It looks as though there are a bunch of connections being accepted but not handled. Can anyone assist? The debug level 7 log file is available if necessary. Thanks again, guys. Cheers, Duncan

Hi all, As an update, it looks like I'm using Stunnel 4.15. I thought it said 4.20, unless I managed to compile an older version. Regardless, I think the problem is happening in both versions. It looks as though it can't catch up on processing cached requests or something. Does that help at all? Cheers, Duncan

Stunnel Forks Out of Control
by Duncan Brown 21 Feb '07

21 Feb '07

Hi all, I apologize if this issue appears in the archives but I've scoured them and can't find any similar instances (if this problem does occur in the archives then if someone could point it out to me I'd be grateful as well). So, here goes: I'm running Stunnel on Debian Linux. I run it in daemon mode and have the .conf file set to listen on a specific port and redirect to another port. Listening on the connecting end of Stunnel is another daemon I've created that listens on the same port for TCP traffic as part of a client-server application I have (a new process is forked for each connection). On the client end is a .NET application that communicates with the server via TCP with Stunnel installed. In my code, I've made sure that whenever a client-server session is finished, the server closes the socket, whether or not there was an error. Now, everything seems to work flawlessly for a period of time (this period of time is variable, from anywhere between 1 day to 1 month). Then, all of a sudden, Stunnel "explodes"; for example, while there might be one or two forks of my own daemon, there might be 128 instances of Stunnel, all of which are in a sleeping state (that is, if I run ps -aux, their "STAT" attribute is "S"), whereas before it exploded it was pretty much a 1:1 relationship. When it "explodes", I have to kill Stunnel and restart it, which is a pain in the rear-end given what I'm trying to do. Why is it doing this? How do I stop it from happening? I apologize again if this has already been brought up somewhere else, but I've been unable to find any references to any similar problems. If it's a "newbie" mistake or something I'll gladly accept it and learn from it. Please find below the information requested for a problem for the mailing list: - I'm using v4.20 - No parameters are used from the command-line when starting Stunnel; it just uses the standard .conf file which I've edited. - Output of "uname -a" : "Linux buffed 2.4.27-2-386 #1 Wed Aug 17 09:33:35 UTC 2005 i686 GNU/Linux" - I'm using libc v6 - Output of "gcc -v" : Reading specs from /usr/lib/gcc-lib/i486-linux/3.3.5/specs Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,pascal,objc,ada,treelang --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-gxx-include-dir=/usr/include/c++/3.3 --enable-shared --enable-__cxa_atexit --with-system-zlib --enable-nls --without-included-gettext --enable-clocale=gnu --enable-debug --enable-java-gc=boehm --enable-java-awt=xlib --enable-objc-gc i486-linux Thread model: posix gcc version 3.3.5 (Debian 1:3.3.5-13) - I'm using OpenSSL v0.9.7e (25 Oct 2004) Thanks in advance for any help.

Stunnel proxy aware

Hi, I'm quite happy with stunnel-4.05 but don't know how to add any of the proxy patches to make my own windows binaries. I also saw that others have wondered http://linode.mirt.net/pipermail/stunnel-users/2006-December/001404.html

Stunnel on AIX 5.3 and AIX 5.2 - Solution
by Trevor Maistry 21 Feb '07

21 Feb '07

Hi, I downloaded stunnel version 4.05, changed the configuration file to use "cc" instead of "gcc" and compiled on AIX 5300-04 and AIX 5200-03. Compilations worked fine. However, you must compile on the machine you want to use it on. Otherwise you will have problems. Copy the "stunnel", "stunnel.pem" and sample "stunnel.conf-sample.in" files into /usr/local/bin. Rename the "stunnel.conf-sample.in" to " "stunnel.conf". Change the "stunnel.conf" accordingly and start "stunnel" like so "./stunnel stunnel.conf". Hope this helps.

slow transfer of smtp

greetings. clients connects normally when not using ssl (stunnel). when using ssl the connection on the client end appears to take about a minute but does eventually work (mail is sent through encrypted). shown below is the log with debug=7 and a space between the area where a "pause" seems to be, ideas on what could be occurring during this time to induce the "pause"? client = machine

"The most recent stable Stunnel version?"
by Roger Fulton 04 Feb '07

04 Feb '07

Hi, I've checked the support pages. I've browsed the mailing list archives. I've perused the ChangeLog file. I can't find an answer to this question: At http://www.stunnel.org/download/binaries.html is stated "The most recent stable Stunnel version is flagged with a red asterisk (*)." I've used two different browsers, and I'll be danged if I see *any* version marked with *any* asterisk, red or otherwise. Would someone kindly direct this Stunnel newbie to the "most recent stable Stunnel version?" TIA.

Oracle JDBC Failover not working
by Dario Mariani 02 Feb '07

02 Feb '07

Hi all. We have a problem here with this configuration. before stunnel: BEA Weblogic, 2 JDBC, server1:1521 and server2:1521 Two SunCluster nodes with Oracle OPS/RAC (active-active conf), with NO shared address. So "server1" and "server2" are the phisical address. after stunnel: the JDBC config is 127.0.0.1:10001 and 127.0.0.1:10002 stunnel client is 10001->server1:11521 and 10002->server2:11521 stunnel server is 11521->localhost:1521 When we shut down the server1 (so oracle, listener and stunnel server is not responding), BEA cannot failover. A quick analisys shows that: 1. the JDBC connects to stunnel client, that accept the connection 2. stunnel client fails to connect to stunnel server 3. stunnel client close the connection with the JDBC 4. the JDBC cannot deal with the situation and doesn't failover. It seems like JDBC doesn't failover when he can open a connection but oracle doesn't reply. What i need is: is possible for Stunnel client to FIRST try to connect to the server, and then eventually accept the connection from the jdbc? Bye, dario.

Intermediate Cert validation problem
by Eric McCombs 01 Feb '07

01 Feb '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 23 Jan '07

23 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. Any help would be appreciated. I would even take an AIX executable for stunnel that works! Or whatever the correct configure options are. Or???? Thanks, Eric This email sent by: Eric S.

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.

Problems with Powerposter?
by Roger Stevens 10 Jan '07

10 Jan '07

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?

RE: [stunnel-users] URL changes in browser to http from https
by Casey Rayman 08 Jan '07

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?

patch: round robin load balancing
by Luke Deller 08 Jan '07

08 Jan '07

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

I am clearly doing something wrong
by David Chase 06 Jan '07

06 Jan '07

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.

STunnel transparent + Solaris
by Corey Johnston 05 Jan '07

05 Jan '07

The documentation mentions that Solaris should support transparent mode for stunnel, yet I receive bind errors when I try to do this. "bind transparent: Cannot assign requested adddress (126)" Seems to suggest that either its actually not possible, or I've got to include something beyond "transparent = yes" in the conf file, or during compilation. Does anybody know if there's anything else special to make this work? Thanks in advance, Corey

Red Hat 7.0, Stunnel 4.20, and my Transparent Proxy Woes
by Richard Anderson 03 Jan '07

03 Jan '07

All, I'm attempting to setup Stunnel 4.20 on a RH7.0 box in transparent mode to essentially act as an SSL accelerator. I've gotten the SSL accelerator part to work (which means RH and Stunnel are working fine). But it's when I enable the transparent feature of stunnel I start having problems. The error it returns is : bind transparent: Cannot assign requested address (99) What I know is this: For transparent option to work with stunnel you must be using linux kernel 2.2. (check...red hat 7.0) Transparent proxy option must be enabled in kernel. (check, enabled, recompiled, and booted off that image) IP_FORWARD must be enabled. (check, set this in the sysctl.conf to do it on bootup) But it still won't work. Does anybody have any other ideas as to what I'm missing? thanks, rich _________________________________________________________________ Get FREE Web site and company branded e-mail from Microsoft Office Live http://clk.atdmt.com/MRT/go/mcrssaub0050001411mrt/direct/01/

Hello, I have installed stunnel 4.20 on Windows2003 server and have created my private key as follow: openssl req -new -days 365 -nodes -config stunnel.cnf -out certreq.pem -keyout stunnel.pem After that I have send certreq.pem to my own CA and have received a certnew.cer file. But what I have to do next because I still receive the message that the CN-name of the certificate is not the same with the given name. I append this certificate (certnew.cer) to my stunnel.pem file like: -----BEGIN RSA PRIVATE KEY----- data here -----END RSA PRIVATE KEY----- -----BEGIN CERTIFICATE----- data here -----END CERTIFICATE----- But this doesn't work. Still receive the message that I also read on the stunnel.conf must I config something here? cert = stunnel.pem key = stunnel.pem ; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile ;CAfile = certs.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem Can anyone tell me what certificate I place where and how config the stunnel.conf so I get this working?

Benchmarks
by Michal Trojnara 17 Dec '06

17 Dec '06

Dear Users, I have updated stunnel performance benchmarks: http://stunnel.mirt.net/perf.html I hope you'll find them useful. The funny thing I currently have 2 hardware accelerator cards, but none of them works: - one of them is too obsolete and its proprietary drivers are no longer available; - the other one is too modern and its PCI-X slot does not work with my ASUS P5WDG2 WS Professional motherboard. I'm pretty sure most users won't even be able to utilize the performance provided by software implementation. The bottleneck will most likely be network connection or the destination server performance. Best regards, Mike

stunnel patch to support URL lookups for parameters (take 2)
by Dan Jakubiec 13 Dec '06

13 Dec '06

Attached is a patch which extends the "connect=" and "CApath=" options to allow these parameters to be obtained dynamically at connect-time via a URL lookup, rather than statically from the stunnel configuration file. It is a generalization of an earlier patch to 4.04 submitted by Jan Piet-Mens which does something similar using LDAP lookups. Feedback is appreciated! Here is a summary of the functionality, along with some notes: 1. The patch was written to allow stunnel to dynamically route and authenticate incoming connections based on parameters found in the client's certificate. 2. Routing and authentication information is obtained by issuing a URL lookup, so the information can be obtained from a variety of local or remote sources. 3. It is particularly useful in high-volume, load-balancing scenarios where many copies of stunnel are running on multiple front-end servers. It allows the destination socket and client certificate verification info to be obtained on-the-fly from a centralized database. 4. Although primarily intended for use with HTTP, this patch uses the libcurl URL library and should work with all of its supported protocols: HTTP, HTTPS, FTP, FTPS, TFTP, DICT, TELNET, LDAP or FILE. As a brief example, an end-user might configure their stunnel as follows: cert = id.pem verify = 2 CApath = ca_dir CAlookup = http://database.stunnel.org/map_client.php?hash=%h [dynamic] accept = 50000 connect = @http://database.stunnel.org/map_client.php?common_name=%n In this scenario, an incoming stunnel connection would obtain it's connect info from database.stunnel.org by sending an HTTP request and passing the common name found in the client certificate. Similarly, the client's certificate would be verified using CA certificates obtained via HTTP lookup to the same host. Comments are appreciated. Thanks, Dan Jakubiec

It is particularly useful in high-volume, load-balancing scenarios where many copies of stunnel are running on multiple front-end servers. It allows the destination socket and client certificate verification info to be obtained on-the-fly from a centralized database. 4. Although primarily intended for use with HTTP, this patch uses the libcurl URL library and should work with all of its supported protocols: HTTP, HTTPS, FTP, FTPS, TFTP, DICT, TELNET, LDAP or FILE. As a brief example, an end-user might configure their stunnel as follows: cert = id.pem verify = 2 CApath = ca_dir CAlookup = http://database.stunnel.org/map_client.php?hash=%h <http://database.stunnel.org/map_client.php?hash=%25h> [dynamic] accept = 50000 connect = @http://database.stunnel.org/map_client.php?common_name=%n<http://database.stunnel.org/map_client.php?common_name=%25n> In this scenario, an incoming stunnel connection would obtain it's connect info from database.stunnel.org by sending an HTTP request and passing the common name found in the client certificate. Similarly, the client's certificate would be verified using CA certificates obtained via HTTP lookup to the same host. Comments are appreciated. Thanks, Dan Jakubiec

Please explain why it will not work for privileged ports. Does this hold even if the master stunnel process runs as root? And what happens to active connections on SIGHUP? Are they simply broken?

What is the error message? A core dump stack backtrace? First performance recommendation is to disable libwrap support: ./configure --disable-libwrap && make clean && make && make install Best regards, Mike

STunnel performance Issues
by Jones Scott - sjones 11 Dec '06

I am having problems will apache and stunnel being able to handle load. I am using stunnel to encrypt my ajp traffic from apache to jboss. This helps me bridge our internal firewall. But during load testing the system starts breaking down. It takes about 1/5 the load to break down apache and stunnel, than directly against my jboss node. Any performance tuning recommendations would be great. I am using stunnel straight out of the box. I will place the configuration file below. Thanks. ; Sample stunnel configuration file by Michal Trojnara 2002-2006 ; Some options used here may not be adequate for your particular configuration ; Please make sure you understand them (especially the effect of chroot jail) ; Certificate/key is needed in server mode and optional in client mode ;cert = /usr/local/stunnel/etc/stunnel/mail.pem ;key = /usr/local/stunnel/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/stunnel/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 ;compression = rle ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ; CApath is located inside chroot jail CApath = certificates ; It's often easier to use CAfile CAfile = /usr/local/stunnel/etc/stunnel/certs.pem ; Don't forget to c_rehash CRLpath ; CRLpath is located inside chroot jail ;CRLpath = /crls ; Alternatively you can use CRLfile ;CRLfile = /usr/local/stunnel/etc/stunnel/crls.pem ; Some debugging stuff useful for troubleshooting ;debug = 7 output = stunnel.log ; Use it for client mode client = yes ; Service-level configuration [ajp] accept = 8009 connect = xxxx2:8009 [sql] accept = 1433 connect = XXXX1:443 *************************************************************************** The information contained in this communication is confidential, is intended only for the use of the recipient named above, and may be legally privileged.

Installing stunnel without need a compiler
by Boxall, John 05 Dec '06

05 Dec '06

Mike et al, I want to be able to automate the installation of stunnel in the same manner that I've already automated our openssh installation, however, I've run into a problem (lack of knowledge) with the "make install" step. This is for Solaris (2.5.1 to 10) and AIX (5.1 to 5.3). I'm not quite ready to create the packages in either Solaris (pkg) or AIX (rpm) formats. At a high level, here is what I would like to achieve: - On a build server (per OS version) - transfer all of the necessary stuff (gcc, openssl, stunnel source, etc.) - install the necessary stuff (gcc, openssl, etc.) - un'tar the stunnel package - run configure (with the appropriate options and paths) - run "make" - tar the stunnel directory & transfer it to a holding system - Put together the necessary pieces on the holding system to install stunnel on all targets. - On a target system (per OS version) - transfer all of the necessary stuff (libgcc, openssl, tar'ed stunnel directory, etc.) - install the necessary stuff (libgcc, openssl, zlib, etc.) - un-tar the stunnel file - run "make install" Using the same flow with our openssh packages, I do not have to install a compiler (gcc) and its support packages. What, if anything, can I do with the stunnel installation to not have to install a compiler? Regards, John Boxall
