Re: stunnel log file fills up with errors very fast
by Alan M Varghese (Nokia) 22 Jan '25

After digging into this a bit further, I was able to confirm that these "retries" are not created by stunnel itself. Rather, stunnel is simply trying to forward the connection attempts from NFS. Changing the NFS mount's "timeo" and "retrans" parameters affects duration for which NFS attempts to connect to the server. Thanks, Alan M Varghese

stunnel log file fills up with errors very fast
by Alan M Varghese (Nokia) 19 Jan '25

19 Jan '25

Hello stunnel users, With stunnel (version: 5.71) setup and running (used to secure NFSv4 mounts), when the network interface is brought down, a huge number of messages are written to the log file (configured with the "output" option) in a very short amount of time. Below are some sample logs: 2025.01.19 14:19:58 LOG5[1044766]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket 2025.01.19 14:19:58 LOG5[1044767]: Service [xxxxx] accepted connection from 127.0.0.1:994 2025.01.19 14:19:58 LOG3[1044767]: s_connect: connect 192.168.x.xx:xxxx: Network is unreachable (101) 2025.01.19 14:19:58 LOG3[1044767]: No more addresses to connect 2025.01.19 14:19:58 LOG5[1044767]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket 2025.01.19 14:19:58 LOG5[1044768]: Service [xxxxx] accepted connection from 127.0.0.1:994 2025.01.19 14:19:58 LOG3[1044768]: s_connect: connect 192.168.x.xx:xxxx: Network is unreachable (101) 2025.01.19 14:19:58 LOG3[1044768]: No more addresses to connect ... This causes the log size to grow very quickly, sometimes overwhelming the filesystem. Log rotation alleviates this issue to some extent. But still, the archived logs would be filled with duplicate logs. This issue has been discussed by another user in the following thread: https://www.stunnel.org/mailman3/hyperkitty/list/[email protected]/… (Note, while the user in the thread above received "Connection refused" messages, here the error is "Network is unreachable". Otherwise, the behaviour with respect to logs is the same.) We would like to know if there is a way to control this connection behaviour from stunnel when "Network is unreachable" in such a manner. If not, is there a way to control/limit the log output from stunnel (without reducing the log level from default)? Steps to reproduce the issue: 1. Mount an NFSv4 filesystem using stunnel (configured to output logs to a file) 2. Bring down the network interfaces such that stunnel is not able to reach the configured server. (Please make sure to not lose access to the server while doing this.) 3. Wait ~300 seconds 4. Bring the interface(s) back up. 5. Examine the log size and contents. Thanks, Alan M Varghese

Issue with OCSP messages in stunnel 5.73 and above
by Alexander Moisseev 02 Jan '25

02 Jan '25

Hello, I am experiencing an issue with stunnel versions 5.73 and above where the server logs are continuously filled with the following message: "OCSP: SSL_get_certificate" This issue does not occur in version 5.72. I am using PSK for encryption and have not configured OCSP. Here are the details of my setup: [.] stunnel 5.74 on amd64-portbld-freebsd14.1 platform [.] Compiled with OpenSSL 3.0.13 30 Jan 2024 [.] Running with OpenSSL 3.0.15 3 Sep 2024 - Server configuration file: ``` setuid = stunnel setgid = nogroup pid = /var/run/stunnel/stunnel.pid [bayes] accept = 6478 connect = 6378 ciphers = PSK PSKsecrets = /usr/local/etc/stunnel/psk.txt cert = /usr/local/etc/stunnel/cert.pem key = /usr/local/etc/stunnel/private.key [fuzzy] accept = 6477 connect = 6377 ciphers = PSK PSKsecrets = /usr/local/etc/stunnel/psk.txt cert = /usr/local/etc/stunnel/cert.pem key = /usr/local/etc/stunnel/private.key ``` - Client configuration file: ``` setuid = stunnel setgid = nogroup pid = /var/run/stunnel/stunnel.pid [bayes] client = yes accept = localhost:6478 connect = host.example.org:6478 ciphers = PSK PSKsecrets = /usr/local/etc/stunnel/psk.txt [fuzzy] client = yes accept = localhost:6477 connect = host.example.org:6477 ciphers = PSK PSKsecrets = /usr/local/etc/stunnel/psk.txt ``` - Relevant log entries: ``` Dec 27 09:00:10 mx stunnel[22113]: LOG3[per-minute]: OCSP: SSL_get_certificate ``` As a temporary workaround, I generated a self-signed certificate and configured stunnel to use it. This has resolved the issue with OCSP messages. However, I believe this is not the intended behavior when using PSK without configuring OCSP. I would appreciate any help or guidance on how to properly configure stunnel to avoid this issue without requiring a self-signed certificate. Thank you, Alexander

[Bug][5.73] stunnel segfault and coredump due to OCSP handling
by stunnel＠benary.org 15 Dec '24

15 Dec '24

Hi everyone, I've recently upgraded from NixOS 24.05 to 24.11 which went from stunnel 5.72 to 5.73 and have since had stunnel crash on me multiple times on different servers (pretty much identical setup however) due to what looks like a memory allocation race? Since 5.73 moved OCSP fetches to a thread, and the problem hasn't ever happened with 5.72 it sounds like an issue specific to that. Someone familiar with the codebase probably has a better idea of what's going on. Given that my updates happened somewhen mid last month and there have been no certificate renewals since (except for one that wouldn't affect the systems that were affected, thanks so much to crt.sh and CT existing) the error message of "OCSP routines::status expired" also seems out of place at least for the certificate itself (the staple may be expired, but stunnel should probably get a new one in that case which may have to do with the error in question). ``` Dec 06 04:43:02 shell stunnel[1124111]: LOG5[per-minute]: OCSP: Certificate accepted Dec 06 04:43:02 shell stunnel[1124111]: 2024.12.06 04:43:02 LOG5[per-minute]: OCSP: Certificate accepted Dec 06 04:43:02 shell stunnel[1124111]: LOG5[per-minute]: OCSP: Certificate accepted Dec 06 04:43:02 shell stunnel[1124111]: 2024.12.06 04:43:02 LOG5[per-minute]: OCSP: Certificate accepted Dec 06 04:43:02 shell stunnel[1124111]: LOG5[per-minute]: OCSP: Certificate accepted Dec 06 04:43:02 shell stunnel[1124111]: 2024.12.06 04:43:02 LOG5[per-minute]: OCSP: Certificate accepted Dec 06 04:43:56 shell stunnel[1124111]: LOG5[ui]: Log file reopened Dec 06 04:43:56 shell stunnel[1124111]: 2024.12.06 04:43:56 LOG5[ui]: Log file reopened Dec 06 04:44:02 shell stunnel[1124111]: LOG3[per-minute]: OCSP: OCSP_check_validity: crypto/ocsp/ocsp_cl.c:351: error:1380007D:OCSP routines::status expired Dec 06 04:44:02 shell stunnel[1124111]: 2024.12.06 04:44:02 LOG3[per-minute]: OCSP: OCSP_check_validity: crypto/ocsp/ocsp_cl.c:351: error:1380007D:OCSP routines::status expired Dec 06 04:44:02 shell stunnel[1124111]: 2024.12.06 04:44:02 LOG4[per-minute]: OCSP: Unknown verification status Dec 06 04:44:02 shell stunnel[1124111]: INTERNAL ERROR: Memory allocated in a different thread at ocsp.c, line 412 Dec 06 04:44:02 shell stunnel[1124111]: LOG4[per-minute]: OCSP: Unknown verification status Dec 06 04:44:02 shell stunnel[1124111]: INTERNAL ERROR: Memory allocated in a different thread at ocsp.c, line 412 Dec 06 04:44:02 shell systemd-coredump[282485]: Process 1124111 (stunnel) of user 988 terminated abnormally with signal 6/ABRT, processing...

Also a huge Thank You for building what has been an integral part of my infrastructure for almost a decade now.

Is it possible for stunnel to reject client connections if the server end cannot connect?
by mohmmad170720＠gmail.com 05 Dec '24

05 Dec '24

Hi all Say we have two machines set up, ClientPC and ServerPC. On ClientPC I run stunnel accepting a connection on a local port and connecting to an stunnel port on ServerPC. On ServerPC I run stunnel accepting a connection on the local stunnel port and connecting to the 'encryption unaware' server on another port on the same ServerPC machine. OK, pretty simple stuff so far. The problem is, when I connect to ClientPC with the 'encryption unaware' client app. then I always get a successful connection, even if there is no server running on ServerPC. Of course once the client has a successful connection, it then performs a write(), and that fails with 'Connection reset by peer'. Really, since there is no server running on ServerPC, I want the connect() to stunnel on ClientPC to fail. Is there a way to do this?

Router + Cudy mesh system
by trashrap22＠gmail.com 26 Nov '24

26 Nov '24

Hi, My stunnel setup was working. I since moved and had to add a Cudy mesh system / extension to the router to extend the internet through the building. Now I can't get stunnel to work again - I have done port forwarding on the Cudy system too. Has anyone done this extentions of router setup and got stunnel to work?

Requests to cloud server that requires host header
by Lorne Kates 13 Nov '24

13 Nov '24

(related to Akamai message from before-- but I have better troubleshooting information). I'm tying to route traffic through stunnel to a "cloud" based-endpoint. That endpoint has a static server name-- test.authorize.net. (This is the dev sandbox for auth.net) But if you do an nslookup on test.authorize.net, you'll get back a different servername and IP, because it's so wonderfully "cloud". Stunnel apparently tries to connect to the nslookup value. The server rejects the request because it can't route it back to test.authorize.net. I've tried adding "delay = yes" and "sni = test.authorize.net", but neither work. To see this in action, a simple setup with any accept, then connect to test.authorize.net:443 in client = yes mode. This is what a valid response looks like (13 -- give me the darn merchant ID in a POST): https://test.authorize.net/gateway/transact.dll This is what you'll get if you try to use stunnel (400 invalid url) : https://23.195.204.150/gateway/transact.dll So how can I get stunnel to send the proper Request Header (host: test.authorize.net) make sure it's using http/1.1, etc?

Is it possible to hide "Acceptable client certificate CA names" during SSL handshaking?
by hshh 12 Nov '24

12 Nov '24

Since version 5.68, when stunnel is configured with verifyPeer=yes, CApath=/path and CAfile=/path/file, the 'Acceptable client certificate CA names' and required certificates are displayed during SSL handshaking. Is it possible to hide this information?

s_ssl_read_eof: SSL_ERROR_WANT_READ: Retrying
by stavultras＠gmail.com 07 Nov '24

07 Nov '24

Hello, i've encountered a very strange issue when you use stunnel 7.53 (doesn't matter actually, happens in 5.68 as well) like this: [server] accept = 443 protocol = socks [client] accept = 1080 protocol = socks connect = server:443 with iptables -A OUTPUT -p tcp -d 10.8.0.1 -j REDIRECT --to-ports 1080, I see in 95% cases in logs for every request from curl: curl http://10.8.0.1 (server's internal IP), however, it never happens if you use client like this: [client] accept = 1080 connect = server:443 and curl -x socks5://127.0.0.1:1080 http://10.8.0.1 (internal server's IP). Technically it affects nothing, but I still guess there's a small time overhead due to retry. Maybe i'm wrong. Please advise. Thanks.

Re: [stunnel-users] CPU 100%
by Eric Eberhard 06 Nov '24

Long ago I had a server with a bad network card. Every once in a while it would spew uncontrollable bytes onto the network. If you open a stunnel connection and it does that this could very well be the problem. If it cheap, try changing the network card. If not, you should be able to look in your firewall/router and it will tell you who is sending what bytes to whomever. See if that machine is indeed streaming the bytes in massive quantities. If not, I would suspect your stunnel is getting stuck in it's own loop. There are a million reasons this can happen (well a few less than a million) - such as maybe a bad library in the FreeBSD or a bad choice in the Makefile - such as doing threads or something in a way your O/S does not like (I use threads=fork or whatever it is, instead of actual threading). You might tinker with some of the options that make the stunnel build and try different ones. Especially if stunnel was compiled on a different version of the O/S - could be differences in bytes in things and who knows what. That is all I can suggest beyond setting the debug level to 7 (I think is highest) and then watching the log file. Eric From: stunnel-users [mailto:[email protected]] On Behalf Of Murrey, Brian J.

socks mode doesn't verify peer

Hello. I'm trying to configure "protocol = socks" with "redirect = 127.0.0.1:80" and "verifyPeer = yes", but accordingly to the debug logs stunnel doesn't verify peer when I'm trying to connect without client's certificate, for an example, from browser: https://192.168.200.131:9013/, where 192.168.200.131 is stunnel server.

"direct" protocol support
by stavultras＠gmail.com 05 Nov '24

05 Nov '24

Hello, is it possible to implement "direct" protocol support? For an example: You have OpenVPN TCP on a server and let's say SSH (or any other TCP software) and you want to use stunnel on the same port or under the same SNI. Configs would like: [server] accept = 443 protocol = direct [client_openvpn_tcp] sni=test.com protocolHost = 127.0.0.1:2000 connect = server:443 accept = 127.0.0.1:2000 [client_ssh] sni=test.com protocolHost = 127.0.0.1:22 connect = server:443 accept = 127.0.0.1:222 I know, you can use "protocol = socks", but in this case you can't use this thing directly with your software that doesn't support socks5 (OpenVPN isn't a fully good example, because it supports socks5 proxy). SSH is a good example if you want to use it under TLS on the same port with OpenVPN TCP and other TCP applications. It will be useful for many other applications without socks5 support and if you won't occupy more than 1 port or SNI. P.S.: I'm still trying to use socks5 code from stunnel to implement "direct" protocol, but i'm not very good at C. Thanks.

stunnel overhead: Tunneling over stunnel - How does this affect MTU?
by Marek Küthe 15 Oct '24

15 Oct '24

Hello, I am tunneling packets via stunnel using OpenVPN. I would now like to have an MTU in my tunnel where no fragmentation occurs. Hence my question: What overhead does stunnel introduce? Is the plaintext with a length one-to-one translated into the ciphertext? How large is the stunnel / TLS header? I look forward to any answer!

External PSK and TLS 1.3
by mike ads 18 Sep '24

18 Sep '24

Hello, I'm looking for a solution to connect to a server using TLS 1.3 and an external PSK. Does stunnel support this? I see that there are configuration options to set TLS 1.3, and configuration options to specify a PSK; if those were used together, would that result in TLS 1.3 with the PSK? If so, how would I choose between ephemeral vs non-ephemeral DH? This doesn't seem to be an option. Ephemeral is an important choice for forward secrecy. Would it default to ephemeral? Thank you.

Re: GMail and OAuth 2.0

I would prefer to use stunnel, which I used for 10 or 20 years until recently, but this proxy is supposed to work for the new problem: SIMON ROB'S EMAIL-OAUTH2-PROXY Go to https://github.com/simonrob/email-oauth2-proxy/releases Download emailproxy-YYYY-MM-DD_pyinstaller-Windows.zip from the most recent release. Unzip the emailproxy-YYYY-MM-DD_pyinstaller-Windows.zip file, extracting the contents to the desired location; avoid the protected system folders such as "Program Files", "Program Files (x86)", etc. Right-click each extracted file, go to Properties, and enable "Unblock"..... Write me at traveler(a)mm.st if you want me to post the rest of the instructions. Maybe experienced people don't need them. I havent' tried to install either this or stunnel yet.

No key from stunnel TLS handshake ?
by atritium＠hushmail.com 31 Aug '24

31 Aug '24

In a TLS handshake, the server presents the signed public key (certificate from a CA) to the client to use so that it doesn't have to be pre-existing in a file on the arbitrary systems making connections. Am I correct that stunnel does NOT do this? It appears stunnel clients MUST have a pre-existing -file- containing the server's signed public key and pointed at in the config file's CAfile setting. Sort of like "authorized_keys" file for ssh, except the certificates have short lifespans before going invalid. This makes authentication unworkable for services that could have thousands of semi-random people connecting, especially with certificate lifespans creeping down to 1 year and probably months. Even if the certificate was bundled in the initial stunnel set-up, remote clients would have to constantly be updating the file. If this is correct, I wonder why stunnel doesn't handle the TLS handshake like a browser and supply the current server public certificate for the client to authenticate. It seems like stunnel is presupposing a handful of clients in close contact who can be constantly fed current certificates to place in files on their machine. Really limits usability of the tool. Or maybe I am missing something (?)

stunnel reload - existing connections
by Stewart Anderson 13 Aug '24

13 Aug '24

> >Hi All, I have seen this question asked a few times, but no replies that I could see. I have my stunnel services set in different service (.conf ) files and when I reload the config they all load fine. What does stunnel do with the existing connections? i.e. when I add a new service config and then do a reload, are the existing connections explicitly dropped and reloaded or can they by dynamically updated without interrupting the connection? For me, this specifically is when I add a new service on a new port, no changes to existing services. cheers Stu >

Problems with stunnel segfaulting on every connection
by jml＠bigjar.com 12 Aug '24

12 Aug '24

Hello, I’m running into a problem with stunnel segfaulting on me. I’m not sure if it’s a NetBSD problem or an stunnel problem. The following combinations work: NetBSD-10.0/stunnel 5.57 Debian/stunnel 5.50 Fedora/stunnel 5.72 Unfortunately, what doesn’t work for me is: NetBSD-10.0/stunnel 5.71 (or 5.7.2) NetBSD-9.x/stunnel 5.71 It looks like stunnel is doing something related to OCSP and the response causes it to crash. The certificate is a wildcard for my domain, bigjar.com. Here’s a snippet of the output right before the segfault: 2024.08.04 13:47:35 LOG7[0]: SNI: no virtual services defined 2024.08.04 13:47:35 LOG7[0]: OCSP stapling: Server callback called 2024.08.04 13:47:35 LOG6[0]: OCSP: The root CA certificate was not found 2024.08.04 13:47:35 LOG5[0]: OCSP: Connecting the AIA responder "http://e5.o.lencr.org" Segmentation fault (core dumped) I rolled back to an earlier certificate issued by sectigo and got the same result: 2024.08.05 15:11:01 LOG7[0]: OCSP stapling: Server callback called 2024.08.05 15:11:01 LOG5[0]: OCSP: Connecting the AIA responder "http://ocsp.sectigo.com" There were some issues getting stunnel to run with the correct version of OpenSSL (the “pkgsrc” version), but those have been fixed.

Here is current setup. Linux Server - Application ==> Stunnel in Client mode ==> Network ==> F5 havingTLS cert to decrypt traffic. We are runnign Stunnel in client mode to encrypt traffic with detination F5. F5 is equipped with TLS cert which decrypts traffic. Setup is working fine but we see some 0.2% traffic is impacted where Stunnel calling app in client side does not receive response. We are not running Stunnel on Server mode on destination. Packet capture does not show any abnormalities. Stunnel used by use is 4.62 coming out of Redhat distribution. We are clueless on traffic drop. Anyone with similar experiences can help?

stunnel for postgres

Hi! I'm trying to set up stunnel for postgres, and cannot get it working. For the moment, I'm just trying to test locally on a Mac. I have set up postgres SSL correctly and confirmed that direct connections to the db with psql work with SSL. Here's the most promising config I've come up with: foreground = yes client = yes [postgresql] protocol = pgsql accept = 127.0.0.1:5433 connect = 127.0.0.1:5432 verify = 0 cert = /opt/homebrew/var/postgresql(a)16/server.crt key = /opt/homebrew/var/postgresql(a)16/server.key CAfile = /opt/homebrew/var/postgresql(a)16/ca.crt Here's what I'm getting: $ PGSSLMODE=disable psql -h 127.0.0.1 -p 5432 -U casey -d postgres -c 'select 1' -At 1 $ PGSSLMODE=require psql -h 127.0.0.1 -p 5432 -U casey -d postgres -c 'select 1' -At 1 $ PGSSLMODE=disable psql -h 127.0.0.1 -p 5433 -U casey -d postgres -c 'select 1' -At psql: error: connection to server at "127.0.0.1", port 5433 failed: server offered SCRAM-SHA-256-PLUS authentication over a non-SSL connection $ PGSSLMODE=require psql -h 127.0.0.1 -p 5433 -U casey -d postgres -c 'select 1' -At psql: error: connection to server at "127.0.0.1", port 5433 failed: FATAL: unsupported frontend protocol 1234.5679: server supports 3.0 to 3.0 Also, is it possible to connect to stunnel via UNIX socket instead of TCP?

OCSP: The root CA certificate was not found
by akos.schneemaier＠gmail.com 06 Aug '24

06 Aug '24

Hi, this is my first post on this mailing list. I did extensive search and tried to resolve the issue I have in pfsense with stunnel. Pfsense CE 2.7.2 uses stunnel 5.71. In my config I created certificate using the acme package with Let's ecrypt. The created certificate works fine in pfsense wenb consol and also with stunnel 5.68 on Debian, but it does not work with stunnel 5.71 on Pfsense. All connections going through stunnel get are timing out and the stunnel log has the following in it: ``` Jul 19 00:53:08 router1 stunnel[2933]: LOG5[6]: Service [XXXX] accepted connection from xxxxxx:46415 Jul 19 00:53:08 router1 stunnel[2933]: LOG6[6]: Peer certificate not required Jul 19 00:53:08 router1 stunnel[2933]: LOG6[6]: OCSP: The root CA certificate was not found Jul 19 00:53:08 router1 stunnel[2933]: LOG5[6]: OCSP: Connecting the AIA responder "http://r10.o.lencr.org" Jul 19 00:56:05 router1 stunnel[2933]: LOG3[6]: Error resolving "r10.o.lencr.org": Address family for nodename not supported (EAI_ADDRFAMILY) Jul 19 00:56:05 router1 stunnel[2933]: LOG3[6]: OCSP: Failed to resolve the OCSP responder address Jul 19 00:56:05 router1 stunnel[2933]: LOG6[6]: OCSP: No OCSP stapling response to send Jul 19 00:56:05 router1 stunnel[2933]: LOG3[6]: SSL_accept: /var/jenkins/workspace/pfSense-CE-snapshots-2_7_2-main/sources/FreeBSD-src-RELENG_2_7_2/crypto/openssl/ssl/record/rec_layer_s3.c:304: error:0A000126:SSL routines::unexpected eof while reading Jul 19 00:56:05 router1 stunnel[2933]: LOG5[6]: Connection reset/closed: 0 byte(s) sent to TLS, 0 byte(s) sent to socket ``` So far i tried: 1. Creating new certificate with acme 2. Unisntall and reinstall both acme and stunnel 3. Tried new cetrificate provider (zerossl) 4. tried adding "OCSPrequire = no" to stunnel.conf based on https://www.stunnel.org/mailman3/hyperkitty/list/[email protected]/… None of the above fixed the issue and not I am not sure how to resolve it. I have another Pfsense installation where all these things work fine. I compaired the stunnel.conf files, but there are identical (except the certificate ofcourse). I looked into the source code and found that the error message is comming from ocsp_params_append_root_ca function in opcs.c, but I ma not a C programer and neither familiar with the stunnel code to figure out more. I hope someone from the stunnel list has some ideas how to proceed based on the logs above. Thank you!

stunnel not able to daisy-chain transparent connections

Hello, I struggled recently, with combining sslh and nginx daisy-chaining ip-transparent connections, and realised the same problem, other users reported, when using stunnel. Now that I have found a fix, which solves my problem with sslh, I checked into the stunnel code, and adapted my proposed fix for stunnel: diff client.c_original client.c 1721a1722,1723 > if (setsockopt(c->fd, SOL_SOCKET, SO_REUSEADDR, &on, sizeof on)) > sockerror("setsockopt SO_REUSEADD"); 1769a1772,1776 > int on = 1; > #ifdef IP_TRANSPARENT > if (setsockopt(c->fd, SOL_IP, IP_TRANSPARENT, &on, sizeof on)) > sockerror("setsockopt SO_IP_TRANSPARENT");> #endif I described my findings here in Detail: https://github.com/ftasnetamot/sslh/blob/2024-07-28--documentation/doc/Dais… This article helped me to figure out, what is wrong: https://blog.cloudflare.com/how-to-stop-running-out-of-ephemeral-ports-and-… I wrote as well some weeks earlier two documents, describing how to configure ip-transparent connections only with routing and no firewall rules involved.

How to verify a certificate
by William Wood 24 Jul '24

24 Jul '24

I have tried everything I can think of, and even though I have certificates that are marked as "valid" when I look at the lock icon for an https: site, I get a verification "fail": CERT: Pre-verification error: self-signed certificate in certificate chain From everything I have read, my understanding is that every chain of certificates starts with a self-signed certificate I have even queried my Windows certificate management, and the issuer of the certificate is Entrust, which is on the list of trusted issuers. Within openssl, I get the same error: error 18 at 0 depth lookup: self signed certificate There is talk of a CApath, as well as lists of trusted issuers, but I do not understand anything within the documentation for stunnel which suggests how to access this information and incorporate it in the functioning of the program. Any help would be much appreciated! Thanks in advance -William Wood

Almost there - openssl verifies remote certificate, but stunnel still fails
by William Wood 24 Jul '24

24 Jul '24

In Windows 10 I have done the following: 1. Created a directory C:\Certificates\ 2. From the Microsoft Management Concole (MMC) I have exported all the "Trusted Root Certificate Authorities\Certificates" as Personal Information exchange .PFX with a passcode 3. Using a Powershell environment, I change directories to C:\Certificates\ and run openssl From the openssl prompt convert the above .PFX file to a .pem file openssl pkcs12 -in All_Trusted.pfx -out All_Trusted.pem -nodes 4. Next I run the following openssl command OpenSSL s_client -CApath c:\Certificates\ -connect api.gainfutures.com:9400 -CAfile All_Trusted.pem After a bunch of output, I get the notification Verification: OK This tells me that the verification has passed the remote certificate. Using this to inform my stunnel configuration, I configure: [GainFuturesConnect] client = yes accept = 127.0.0.1:8080 connect = 192.111.85.171:9400 CAfile = C:\Certificates\All_Trusted.pem CApath = C:\Certificates\ securityLevel = 1 verifyChain = yes checkHost = api.gainfutures.com:9400 sslVersion = TLSv1.2 sslVersionMax = TLSv1.2 ciphers = DHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256 Although the preverification succeeds at each "depth", the verification fails at the end: CERT: Pre-verification succeeded (**Note, this is a change from before I added the above CAfile and CApath values**) CERT: Subject checks failed Rejected by CERT at depth=0: C=GB, L=London, O=Gain Capital UK Limited, CN=*.gainfutures.com Remove session callback TLS alert (write): fatal: internal error SSL_connect: ssl/statem/statem_clnt.c:2091: error:0A000086:SSL routines::certificate verify failed So my question becomes two parts: 1. How do I get the Subject checks to pass for CERT; 2. How do I get rid of the TLS "write" alert which is an internal error? Thank you -William Wood

Re: Trying to get stunnel to verify remote server certificate
by William Wood 18 Jul '24

18 Jul '24

Thank you Mike for your reply. I apologize for my lack of experience with networks. One thing that I personally did not understand in using stunnel is that my SSL traffic that I want to "wrap" needs to be directed at the "accept" port, and that the stunnel wrap THEN sends it out over the connect port with the SSL "magic" applied. With that in mind, I have amended my configuration, and I have a new problem (s?): client = yes accept = 127.0.0.1:8080 connect = 192.111.85.171:9400 cert = C:\Certificates\WMW_trade_csr.pem CAfile = C:\Certificates\ca-cert1.pem securityLevel = 0 verifyPeer = yes checkHost = api.gainfutures.com sslVersion = TLSv1.2 sslVersionMax = TLSv1.2 This binds the service to 127.0.0.1:8080 So far so good. When I start my program, which directs its output stream to the "accept" port, the stunnel log now responds as I send messages: (I have pulled out just the last part before the error) 2024.07.18 12:19:45 LOG6[1150]: Peer certificate required 2024.07.18 12:19:45 LOG7[1150]: TLS state (connect): before SSL initialization 2024.07.18 12:19:45 LOG7[1150]: Initializing application specific data for session authenticated 2024.07.18 12:19:45 LOG7[1150]: TLS state (connect): SSLv3/TLS write client hello 2024.07.18 12:19:45 LOG7[1150]: TLS state (connect): SSLv3/TLS write client hello 2024.07.18 12:19:45 LOG7[1150]: TLS state (connect): SSLv3/TLS read server hello This looks okay to me so far 2024.07.18 12:19:45 LOG7[1150]: Verification started at depth=2: C=US, O="Entrust, Inc.", OU=See www.entrust.net/legal-terms, OU="(c) 2009 Entrust, Inc. - for authorized use only", CN=Entrust Root Certification Authority - G2 2024.07.18 12:19:45 LOG6[1150]: CERT: Pre-verification error ignored: self-signed certificate in certificate chain 2024.07.18 12:19:45 LOG6[1150]: OCSP: Certificate chain verification disabled 2024.07.18 12:19:45 LOG6[1150]: Certificate accepted at depth=2: C=US, O="Entrust, Inc.", OU=See www.entrust.net/legal-terms, OU="(c) 2009 Entrust, Inc. - for authorized use only", CN=Entrust Root Certification Authority - G2 2024.07.18 12:19:45 LOG7[1150]: Verification started at depth=2: C=US, O="Entrust, Inc.", OU=See www.entrust.net/legal-terms, OU="(c) 2009 Entrust, Inc. - for authorized use only", CN=Entrust Root Certification Authority - G2 2024.07.18 12:19:45 LOG7[1150]: CERT: Pre-verification succeeded 2024.07.18 12:19:45 LOG6[1150]: OCSP: Certificate chain verification disabled 2024.07.18 12:19:45 LOG6[1150]: Certificate accepted at depth=2: C=US, O="Entrust, Inc.", OU=See www.entrust.net/legal-terms, OU="(c) 2009 Entrust, Inc. - for authorized use only", CN=Entrust Root Certification Authority - G2 2024.07.18 12:19:45 LOG7[1150]: Verification started at depth=1: C=US, O="Entrust, Inc.", OU=See www.entrust.net/legal-terms, OU="(c) 2012 Entrust, Inc. - for authorized use only", CN=Entrust Certification Authority - L1K 2024.07.18 12:19:45 LOG7[1150]: CERT: Pre-verification succeeded 2024.07.18 12:19:45 LOG6[1150]: OCSP: Certificate chain verification disabled 2024.07.18 12:19:45 LOG6[1150]: Certificate accepted at depth=1: C=US, O="Entrust, Inc.", OU=See www.entrust.net/legal-terms, OU="(c) 2012 Entrust, Inc. - for authorized use only", CN=Entrust Certification Authority - L1K 2024.07.18 12:19:45 LOG7[1150]: Verification started at depth=0: C=GB, L=London, O=Gain Capital UK Limited, CN=*.gainfutures.com 2024.07.18 12:19:45 LOG7[1150]: CERT: Pre-verification succeeded 2024.07.18 12:19:45 LOG6[1150]: CERT: Host name "api.gainfutures.com" matched with "*.gainfutures.com" 2024.07.18 12:19:45 LOG4[1150]: CERT: Certificate not found in local repository not sure what this indicates (not found in local repository) 2024.07.18 12:19:45 LOG4[1150]: Rejected by CERT at depth=0: C=GB, L=London, O=Gain Capital UK Limited, CN=*.gainfutures.com 2024.07.18 12:19:45 LOG7[1150]: Remove session callback 2024.07.18 12:19:45 LOG7[1150]: TLS alert (write): fatal: bad certificate 2024.07.18 12:19:45 LOG3[1150]: SSL_connect: ssl/statem/statem_clnt.c:2091: error:0A000086:SSL routines::certificate verify failed After looking on the internet, I think that the [TLS alert (write): fatal: bad certificate] may refer to the cert = (file.pem), which in this case is a certificate I had made and verified by a trusted authority. The rejected by CERT is clearly referring to the certificate which comes from the server located at the other end of the "connect" port. I have looked specifically at this certificate, and the chain is comprised of two authenticated certificates, with a self-authenticated third certificate. As an example, when I change the "checkHost =" to an IP address, the error message changes: 2024.07.18 12:40:45 LOG7[1157]: CERT: Pre-verification succeeded *2024.07.18 12:40:45 LOG4[1157]: CERT: Subject checks failed *2024.07.18 12:40:45 LOG4[1157]: Rejected by CERT at depth=0: C=GB, L=London, O=Gain Capital UK Limited, CN=*.gainfutures.com 2024.07.18 12:40:45 LOG7[1157]: Remove session callback *2024.07.18 12:40:45 LOG7[1157]: TLS alert (write): fatal: unknown CA What seems to be consistent is that the remote certificate is being rejected because there is a self-authenticated certificate as the third part of the chain. I have tried the following: CAfile = C:\Certificates\ca-cert.pem (CA file which comes with openssl, I believe) which gives the same results. CAfile = C:\Certificates\ca-cert1.pem (Here I have added the chain certificates from file gain-futures-chain.pem) same results CAfile = C:\Certificates\ca-cert2.pem (Here I have added the chain certificates from file gain-futures-chainpumpbut removed the self-signed part) same results CAfile =C:\Certificates\ca-cert3.pem (ca-cert3.pem contains ONLY the certificates from gain-futures-chain.pem) same results CAfile =C:\Certificates\gain-futures-chain.pem This causes the service NOT to be bound, and throws what look like a bunch of openssl errors So it appears that I am actually probing the certificate that the remote server is sending me. I am still not clear on the role of CAfile, because of the behavior I have outlined. Do I need somehow to find a CAfile which recognizes and validates the certificate from the remote server? Thank you again! -William Wood

Trying to get stunnel to verify remote server certificate

I have downloaded the remote certificates, and configured stunnel: client = no accept = 127.0.0.1:9400 connect = 192.111.85.171:9400 cert = C:\Certificates\gain-futures-chain.pem verifyChain = yes verifyPeer = yes checkHost = 192.111.85.171 checkIP = api.gainfutures.com sslVersion = TLSv1.1 options = NO_SSLv2 options = NO_SSLv3 OCSPaia = yes This results in the failure to initialize the tLS context: 2024.07.15 08:40:50 LOG7[service]: Found 1 ready file descriptor(s) 2024.07.15 08:40:50 LOG7[service]: FD=580 ifds=r-x ofds=r-- 2024.07.15 08:40:50 LOG7[service]: FD=640 ifds=r-x ofds=--- 2024.07.15 08:40:50 LOG7[service]: Dispatching a signal from the signal pipe 2024.07.15 08:40:50 LOG7[service]: Processing SIGNAL_RELOAD_CONFIG 2024.07.15 08:40:50 LOG6[service]: Initializing inetd mode configuration 2024.07.15 08:40:50 LOG7[service]: Running on Windows 6.2 2024.07.15 08:40:50 LOG5[service]: Reading configuration from file C:\Program Files (x86)\stunnel\config\stunnel.conf 2024.07.15 08:40:50 LOG5[service]: UTF-8 byte order mark not detected 2024.07.15 08:40:50 LOG5[service]: FIPS mode disabled 2024.07.15 08:40:50 LOG6[service]: Compression disabled 2024.07.15 08:40:50 LOG7[service]: No PRNG seeding was required 2024.07.15 08:40:50 LOG6[service]: Initializing service [GainFuturesConnect] 2024.07.15 08:40:50 LOG7[service]: Initializing context [GainFuturesConnect] 2024.07.15 08:40:50 LOG6[service]: OpenSSL security level is used: 2 2024.07.15 08:40:50 LOG7[service]: Ciphers: HIGH:!aNULL:!SSLv2:!DH:!kDHEPSK 2024.07.15 08:40:50 LOG7[service]: TLSv1.3 ciphersuites: TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256 2024.07.15 08:40:50 LOG7[service]: TLS options: 0x2100000 (+0x2000000, -0x0) 2024.07.15 08:40:50 LOG6[service]: Session resumption enabled 2024.07.15 08:40:50 LOG6[service]: Loading certificate from file: C:\Certificates\gain-futures-chain.pem 2024.07.15 08:40:50 LOG3[service]: error queue: ssl/ssl_rsa.c:472: error:0A080002:SSL routines::system lib 2024.07.15 08:40:50 LOG3[service]: error queue: crypto/bio/bss_file.c:300: error:10080002:BIO routines::system lib 2024.07.15 08:40:50 LOG3[service]: SSL_CTX_use_certificate_chain_file: crypto/bio/bss_file.c:297: error:80000002:system library::No such file or directory 2024.07.15 08:40:50 LOG3[service]: Service [GainFuturesConnect]: Failed to initialize TLS context 2024.07.15 08:40:50 LOG3[service]: Configuration failed 2024.07.15 08:40:50 LOG7[service]: Deallocating temporary section defaults 2024.07.15 08:40:50 LOG7[service]: Cleaning up context [(null)] 2024.07.15 08:40:50 LOG7[service]: Deallocating section [GainFuturesConnect] 2024.07.15 08:40:50 LOG7[service]: Cleaning up context [GainFuturesConnect] 2024.07.15 08:40:50 LOG3[service]: Failed to reload the configuration file This is the best I can gather regarding getting verification of the REMOTE certificate.

How to connect to a website through a port
by William Wood 02 Jul '24

02 Jul '24

Hi - I am trying to connect securely to a website from a Windows 10 machine: gainfutures.com through the port: 9400 I am told I need to do this using SSL. I have a python script which successfully connects through their non-secure ports. I am given no other information about what is needed for the connection, so I am asking how to do this. I have added to the configuration file: accept=gainfutures.com:9400 connect=gainfutures:9400 The "accept" line results in the error: Can't assign requested address (WSAEADDRNOTAVAIL) (10049) the "connect" line has no effect in the messages. Any suggestions would be much appreciated. Thank you -WW

How to specify OCSP responder URL in "server" mode?
by sbworkde＠gmail.com 02 Jul '24

02 Jul '24

I want to specify OCSP responder URL while stunnel in "server" mode. I tried to use the option "OCSP" in configuration file, but it only works in "client" mode. The OCSP responder URL is always read form AIA while stunnel is in "server" mode, even when I set "OCSPaia = no". Is there a way to specify OCSP resonder URL for "server" mode?

GRE over Stunnel
by marslogout＠gmail.com 17 May '24

Hello, is it possible to use GRE with Stunnel? I know that GRE is a protocol different from TCP, but I would like to hear your opinion on this matter. If GRE is not supported, would it be correct to replace it with PPTP without encryption?

Stunnel with no encryption
by Castro, Flavio 16 May '24

16 May '24

Hello, I am trying to configure Stunnel to use the insecure cipher PSK-NULL-SHA@SECLEVEL=0 but am encountering issues where a different cipher appears to be negotiated instead. My goal is to authenticate endpoints without encryption. Here are the details of my setup: Stunnel Version: 5.63 Operating System: Ubuntu Stunnel Configuration: ; Stunnel Configuration ; Global Options fips = no output = /var/log/stunnel.log ; Specify the pre-shared key file PSKsecrets = /etc/stunnel/psk.txt sslVersion = TLSv1.2 ; PSK Server Configuration [PSK server] accept = 192.168.20.11:5074 connect = 192.168.30.11:5074 ciphers = PSK-NULL-SHA ; In OpenSSL, I can achieve my goal using the following command, which works as expected: openssl s_client -port 5074 -cipher "PSK-NULL-SHA@SECLEVEL=0" -psk 4f8583bca4d311ee9fd6034d1fcbd7c3 -tls1 However, with Stunnel, it appears a different cipher is negotiated, and I do not see any error messages in the logs. I tcpdumped the connection and observed the traffic is being encrypt which was not the case when using openssl. In my usecase I need to authenticate endpoints without encryption, hence the use of PSK-NULL-SHA@SECLEVEL=0. Could you please advise on how to properly configure Stunnel to use the PSK-NULL-SHA@SECLEVEL=0 cipher, or if this is supported? Thank you for your assistance. Flavio Castro
