[Stunnel] [Android x86] Compilation
by John Fisherman 22 Aug '16

22 Aug '16

Dear all, I am currently trying to make stunnel work for an Android x86 architecture. The android binary found on the stunnel official website is not supported on x86 architecture, so I'd like to cross-compile it myself using the 'configure' options. I did not find much informations about this around the web, could you give me some advices or at least tell me if it is possible to make Stunnel work on an Android x86 device ? Thanks in advance, Regards, - John

Stunnel exits with timeout
by SP 19 Aug '16

19 Aug '16

Summary of problem (configuration and log details below): I am attempting to configure Stunnel to run a pop3s service on our server so that users can retrieve email securely. Stunnel is started as a systemctl service. If I include both the following in the stunnel.conf: accept = mail.myserver.net:995 connect = localhost:110 then systemctl will exit immediately with: Service [pop3s]: Each service must define two endpoints stunnel.service: Control process exited, code=exited status=1 Failed to start SSL tunnel for network daemons. If I comment the connect to 110 then it will start and hang then eventually timeout: stunnel.service: Failed with result 'timeout'. Below is my stunnel.conf and log excerpt from the start with the connect to 110 commented out. I would greatly appreciate any advice. ---stunnel.conf setuid = nobody setgid = nobody pid = /usr/local/var/lib/stunnel/var/run/stunnel.pid foreground = yes ;debug = info debug = 7 sslVersion = TLSv1.2 output = /usr/local/var/lib/stunnel/var/log/stunnel.log ;ciphers = HIGH:MEDIUM:+DH:!SSLv2:!aNULL:+SHA256:+SHA1:+MD5 ciphers = HIGH:+3DES:+DH:!aNULL:!SSLv2 transparent = yes delay = no fips = no compression = deflate client = no [pop3s] accept = mail.myserver.net:995 ;connect = localhost:110 cert = /etc/stunnel/stunnel.pem key = /etc/stunnel/stunnel.pem exec = /usr/local/sbin/gnu-pop3d execargs = --debug=000 --mdn --timeout=60 --ipv6 ----log excerpt ----- 2016.08.17 15:08:55 LOG7[ui]: Clients allowed=500 2016.08.17 15:08:55 LOG5[ui]: stunnel 5.35 on x86_64-unknown-linux-gnu platform 2016.08.17 15:08:55 LOG5[ui]: Compiled/running with OpenSSL 1.0.2h 3 May 2016 2016.08.17 15:08:55 LOG5[ui]: Threading:PTHREAD Sockets:POLL,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI 2016.08.17 15:08:55 LOG7[ui]: errno: (*__errno_location ()) 2016.08.17 15:08:55 LOG5[ui]: Reading configuration from file /etc/stunnel/stunnel.conf 2016.08.17 15:08:55 LOG5[ui]: UTF-8 byte order mark not detected 2016.08.17 15:08:55 LOG7[cron]: Cron thread initialized 2016.08.17 15:08:55 LOG5[ui]: FIPS mode disabled 2016.08.17 15:08:55 LOG6[ui]: Compression enabled: 1 method(s) 2016.08.17 15:08:55 LOG7[ui]: Snagged 64 random bytes from /dev/urandom 2016.08.17 15:08:55 LOG7[ui]: PRNG seeded successfully 2016.08.17 15:08:55 LOG6[ui]: Initializing service [pop3s] 2016.08.17 15:08:55 LOG6[ui]: Loading certificate from file: /etc/stunnel/stunnel.pem 2016.08.17 15:08:55 LOG6[ui]: Certificate loaded from file: /etc/stunnel/stunnel.pem 2016.08.17 15:08:55 LOG6[ui]: Loading private key from file: /etc/stunnel/stunnel.pem 2016.08.17 15:08:55 LOG6[ui]: Private key loaded from file: /etc/stunnel/stunnel.pem 2016.08.17 15:08:55 LOG7[ui]: Private key check succeeded 2016.08.17 15:08:55 LOG7[ui]: DH initialization 2016.08.17 15:08:55 LOG7[ui]: Could not load DH parameters from /etc/stunnel/stunnel.pem 2016.08.17 15:08:55 LOG6[ui]: Using dynamic DH parameters 2016.08.17 15:08:55 LOG7[ui]: ECDH initialization 2016.08.17 15:08:55 LOG7[ui]: ECDH initialized with curve prime256v1 2016.08.17 15:08:55 LOG7[ui]: SSL options: 0x03004004 (+0x03004000, -0x00000000) 2016.08.17 15:08:55 LOG5[ui]: Configuration successful 2016.08.17 15:08:55 LOG7[ui]: Listening file descriptor created (FD=7) 2016.08.17 15:08:55 LOG7[ui]: Option SO_REUSEADDR set on accept socket 2016.08.17 15:08:55 LOG7[ui]: Service [pop3s] (FD=7) bound to 60.62.114.105:995 2016.08.17 15:08:55 LOG6[cron]: Executing cron jobs 2016.08.17 15:08:55 LOG7[ui]: Created pid file /usr/local/var/lib/stunnel/var/run/stunnel.pid 2016.08.17 15:08:55 LOG5[cron]: Updating DH parameters 2016.08.17 15:10:01 LOG5[cron]: DH parameters updated 2016.08.17 15:10:01 LOG6[cron]: Cron jobs completed in 66 seconds 2016.08.17 15:10:01 LOG7[cron]: Waiting 86334 seconds 2016.08.17 15:10:25 LOG7[ui]: Found 1 ready file descriptor(s) 2016.08.17 15:10:25 LOG7[ui]: FD=4 events=0x2001 revents=0x1 2016.08.17 15:10:25 LOG7[ui]: FD=7 events=0x2001 revents=0x0 2016.08.17 15:10:25 LOG7[ui]: Dispatching signals from the signal pipe 2016.08.17 15:10:25 LOG7[ui]: Processing SIGNAL_TERMINATE 2016.08.17 15:10:25 LOG5[ui]: Terminated 2016.08.17 15:10:25 LOG7[ui]: Closing service [pop3s] 2016.08.17 15:10:25 LOG7[ui]: Service [pop3s] closed (FD=7) 2016.08.17 15:10:25 LOG7[ui]: Service [pop3s] closed 2016.08.17 15:10:25 LOG7[ui]: removing pid file /usr/local/var/lib/stunnel/var/run/stunnel.pid

Logging Issues Causing Crash?
by Randall LeJeune 08 Aug '16

08 Aug '16

Hello all, Has anyone experienced a full log file causing stunnel issues in the past? We tried upgrading from 4.56 to 5.17 and the upgrade seemed to go fine at first, but a day or so later we began to have some disconnects. Later we downgraded to 5.01 which worked OK at first, but then we ran into the same kinds of problems again after a few days. We eventually put the stunnel.log file on a separate filesystem, but I am curious, has anyone else experienced any issues like this? Thanks, Randy

Config was working. Now it isn't after reboot
by Lee Savidge 02 Aug '16

02 Aug '16

I just reinstalled stunnel the latest version. When running I went through the creation of the pem file. I put in UK for the country code and the company name and put a . for everything else. It finished, I start the GUI and it works. I edited the config file to comment out the gmail IMAP section and reload it and it was fine. I rebooted, now it tells me tehre is an error in the config file. Why? I keep getting this problem. Rebooting seems to break the config somehow. Log shows this when stunnel starts: [ ] Cron thread initialized [ ] Running on Windows 6.1 [ ] No limit detected for the number of clients [.] stunnel 5.35 on x86-pc-msvc-1500 platform [.] Compiled/running with OpenSSL 1.0.2h-fips 3 May 2016 [.] Threading:WIN32 Sockets:SELECT,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI [ ] errno: (*_errno()) [ ] GUI message loop initialized [ ] Running on Windows 6.1 [.] Reading configuration from file stunnel.conf [.] UTF-8 byte order mark detected [.] FIPS mode disabled [ ] Compression disabled [ ] Snagged 64 random bytes from C:/.rnd [ ] Wrote 1024 new random bytes to C:/.rnd [ ] PRNG seeded successfully [ ] Initializing service [gmail-pop3] [ ] No certificate or private key specified [ ] SSL options: 0x03000004 (+0x03000000, -0x00000000) [ ] Initializing service [gmail-smtp] [ ] No certificate or private key specified [ ] SSL options: 0x03000004 (+0x03000000, -0x00000000) [.] Configuration successful [ ] Listening file descriptor created (FD=388) [ ] Option SO_EXCLUSIVEADDRUSE set on accept socket [ ] Service [gmail-pop3] (FD=388) bound to 127.0.0.1:110 [ ] Listening file descriptor created (FD=392) [ ] Option SO_EXCLUSIVEADDRUSE set on accept socket [!] bind: Permission denied (WSAEACCES) (10013) [!] Error binding service [gmail-smtp] to 127.0.0.1:25 [ ] Closing service [gmail-pop3] [ ] Service [gmail-pop3] closed (FD=388) [ ] Service [gmail-pop3] closed [ ] Closing service [gmail-smtp] [ ] Service [gmail-smtp] closed [!] Server is down [ ] Executing cron jobs [ ] Cron jobs completed in 0 seconds [ ] Waiting 86400 seconds The config file contains this: debug = debug output = stunnel.log [gmail-pop3] client = yes accept = 127.0.0.1:110 connect = pop.gmail.com:995 verifyChain = yes CAfile = ca-certs.pem checkHost = pop.gmail.com OCSPaia = yes [gmail-smtp] client = yes accept = 127.0.0.1:25 connect = smtp.gmail.com:465 verifyChain = yes CAfile = ca-certs.pem checkHost = smtp.gmail.com OCSPaia = yes I have pasted in only the stuff that isn't commented out.

Client-side SNI
by Vincent Deschenes 01 Aug '16

01 Aug '16

Hi, Anyone know if there is anything special to do to get ServerName sent when using stunnel in client mode to be able to connect to SNI enabled server? Using latest version of stunnel and openssl. Will stunnel use the name specified in the "connect=" config ? Thanks, Regards, Vincent Deschenes Ing. PMP Director of Operations Stelvio Inc. (+1) 514-281-8570

stunnel only sends some emails, not all, and only on second attempt
by Martin Jaquess 28 Jul '16

28 Jul '16

Hi I'm using the latest Stunnel (5.35), running under Windows Server 2000, to download emails from Outlook(Office365)/Outlook 2016 to another email client called OfficeTalk which only supports unencrypted POP3, so it can't access Outlook directly. First problem is that although most emails are downloaded without problem, some stubbornly and consistently refuse to be downloaded. This omission doesn't seem related to attachments, encoding, size, date, or anything else that I can see. Has anyone else experienced this or have any idea why it might be happening?? Second problem is that the first download doesn't produce anything, but if I run the request again, it works - the only difference in the log files is the IP addresses I'd greatly appreciate any advice on this - I've checked the threads but can't find anything similar. Many thanks in advance Martin Config file for all attempts is:debug=7 output = c:\program files\stunnel\stunnel.log [outlook-pop3] client = yes accept = 127.0.0.1:110 connect =

AiX 7.1 TL3 SP6 - Stunnel Memory Usages grows after 24 hours
by Benjamin, Earl 19 Jul '16

19 Jul '16

Hello Everyone, I am running Stunnel-5.29 in AiX 7.1 TL3 SP6. I have added the DH param to the bottom of my CERT file. After approximately 24 hours or so the Stunnel CPU usage jumps to about 50% and after a few days to about 90%. Is there a configuration setting I've missed or compile option I need to consider? Thanks for your assistance in advance. Below is a cleaned up version of my config file. -Earl ------------------------------------------------- ; Verify peer certificate verify = 2 ; Certificate/key is needed in server mode and in client mode cert = /Server-certificate-all.pem key = /Server-certificate-all.pem CAfile = /all_root_ca.pem ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = TLSv1 ; PID path pid = /etc/oraserver_stunnel.pid ; Turn off Nagle algorithm socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Debug level debug = 2 ; Use it for client mode client = no ; Ciphers ciphers = DHE-RSA-AES256-SHA ; Service-level configuration [ oraserver_DB ] accept = 15210 connect = server:1622 [ oraserver_ASM ] accept = 15211 connect = server:1621 This message and any attachments are solely for the use of intended recipients.

Man in the middle attack possibility
by Abhinav Srivastava 19 Jul '16

19 Jul '16

Hi, I'm trying to use stunnel to provide encryption for my application to server communication. Server is already ssl aware. I configured my app to talk to localhost:xyz, and configured stunnel in client mode to relay traffic from localhost:<xyz> to actual service. The stunnel to service ssl protocol would use the server certificate, as server is already ssl aware. For any reason if stunnel is not running it would become possible for a non-elevated attacker/malware to spin up a tcp server listening to xyz, essentially taking advantage of my re-configuration of app to talk to localhost:xyz, and spoof the actual server. Even if my app to server protocol had some anti-spoofing mechanism say e.g., reverse CHAP, the malware can easily relay the challenge and response by using the actual service. In my case the actual app is iscsi initiator software that is not in my control and cant be modified, while the server is an iscsi tcp server which I am free to modify. Are there any guidance/best practices around preventing this attack with stunnel? Thanks Abhinav

Client certificates now required by default?

stunnel and hosts.allow
by Yousef Alhashemi 05 Jul '16

05 Jul '16

Hi, This may be a little bit off-topic, but does anyone here use stunnel with pan? My connections to stunnel (in pan) are always refused by libwrap. I was looking for the right rule to add to /etc/hosts.allow but nothing seems to work aside from "ALL : ALL" (which is obviously not good) and "nntps: KNOWN". Is the latter reasonable? The hosts_access(5) manpage is confusing to say the least. It mentions that daemon (the first token on any line) is the name of the daemon running the process, which would be "stunnel" in my case, but using "stunnel : LOCAL" or even "stunnel : ALL" doesn't work. The rule that seems to work, as mentioned, is "nntps : KNOWN" ("nntps" being the group name in stunnel.conf). What's even more confusing to me is that "nntps : LOCAL" does not work either. Nor does "nntps : localhost 127.0.0.1", "nntps : localhost", "nntps : 127.0.0.1", or "nntps : 192.168.1.". Pan is running on the same machine as stunnel so all connections must be coming from localhost. Why do these rules not trigger? Either way, I'd like to know the "least permissive" hosts.allow rule that would allow me to connect to my news provider from pan, and/or whether "nntps : KNOWN" is a safe option. Thanks, Yousef

Hi, What do you think about the attached patch that fixes yet another OpenSSL 1.1.x compilation problem: the OpenSSL developers dropped the ssl23.h file altogether? Thanks for your work on stunnel!

Failed to redirect http to https
by Doris Hongmei 27 Jun '16

27 Jun '16

Hi Support, I setup stunnel to a web server with apache Configuration like below, --- /usr/local/etc/stunnel/stunnel.conf ---------- ; It is recommended to drop root privileges if stunnel is started by root setuid = nobody setgid = nobody ; TLS front-end to a web server [https] accept = 443 connect = 127.0.0.1:80 cert = /usr/local/etc/stunnel/stunnel.pem --- end of /usr/local/etc/stunnel/stunnel.conf ---------- After stunnel started, https://xxx/ is working, http://xxx/ is also still working , which doesn't redirect to https://xxx automatically. As my understanding, all the connections from http should redirect to https through stunnel, right? What steps did I miss? I need your help. Thanks.

Re: [stunnel-users] FW: Stunnel with IIS8 on server 2012 64 bit
by J. Michael Drew 24 Jun '16

24 Jun '16

Jose, I have discovered what I did wrong. I did the original stunnel installs from the command line and then installed the stunnel service from the command line as well. When I installed the stunnel service it would break the website. So I removed the service (I thought) then I copied a shortcut to stunnel.exe to the Win start up> program folder. Both sites started working on the servers as long as I was logged in through an RDP session. I uninstalled everything and reinstalled. Stunnel 5.32 installs a Windows GUI on Server 2012 as well so I went back and used the Windows server 2012 desktop applications to install the windows service and to stop the GUI application. Everything is now working as expected. It appears that I was running two instances of stunnel at the same time and I didn’t completely remove the original stunnel service.

Michael Drew; stunnel-users(a)stunnel.org Subject: Re: [stunnel-users] FW: Stunnel with IIS8 on server 2012 64 bit Michael, I guess what you want to do is to be able to connect to your internal Webserver via your Win2012 stunnel proxy using a URL like: https://yourwin2012dnsname:9001/ <https://yourwin2012dnsname:9009/> if that is correct, I suggest to adjust your configuration as follows: 1. Your stunnel mode must be server, not client. So adjust your service stanza as follows: [CLI9F529A0A] accept=9001 connect=10.xxx.xxx.xxx:9009 client=no 2. In your current configuration stunnel is listening only in the localhost ipv4 address (127.0.0.1). Therefore, you can only connect when you are logged on the server, you can't connect from a remote client. Hope this helps you clarify what's going on. Regards, Jose From: J.

Stunnel connection host address not appearing in sent message.

I am using stunnel to enable SoapUI Mock Servers to support SSL connections. I am attempting to send the following SSL message: https://services.greenbuttondata.org/oauth/token?grant_type=client_credentia ls <https://services.greenbuttondata.org/oauth/token?grant_type=client_credenti als&scope=FB=39_40> &scope=FB=39_40 Using Wireshark, it appears the message being sent is POST /oauth/token?grant_type=client_credentials&scope=FB=39_40 which is receiving the following response: Error 404 (Not Found) The contents of the stunnel.conf file is: ; ***************************************************************** : * Service definitions (at least one service has to be defined) * ; ***************************************************************** ; ***************************************************************** ; * Resource Server * ; ***************************************************************** [resourceServer] accept=localhost:8080 connect=services.greenbuttondata.org:443 ciphers=AES128-SHA client=yes cert=/etc/stunnel/stunnel.pem verify=0 ; ***************************************************************** ; * Authorization Server * ; ***************************************************************** [authorizationServer] accept=localhost:8082 connect=services.greenbuttondata.org:443 ciphers=AES128-SHA client=yes cert=/etc/stunnel/stunnel.pem verify=0 [tpserver] accept=localhost:8444 connect=localhost:8081 cert=/etc/stunnel/stunnel.pem ciphers=AES128-SHA client=no verify=0 The HTTP log from SoapUI shows the following: "POST /oauth/token?grant_type=client_credentials&scope=FB=36_40 HTTP/1.1" "Accept-Encoding: gzip.deflate" "Content-Type: application/json" "Authorization: Basic UkVHSV...

Any assistance would be greatly appreciated. Best regards, Don Donald F.

Compiling for Windows CE
by Bart de Waal 15 Jun '16

15 Jun '16

Hello, Are there more up to date instructions for compiling on Windows CE? I found the version here that works but is old and missing one of the features I need to connect to the server: http://www.usenix.org.uk/mirrors/stunnel/wce/ The instructions for building say you need evt2002web_min.exe, which as far as I can tell is no longer available. I can't get the newer version (evc4.exe) to work on a modern windows system (or under linux using wine) either. I think the CE version is still being used, as I saw references to it in the latest changelog. If someone has a more modern guide to building it I would appreciate it. Thanks, Bart de Waal
