This can be O/S dependent – some O/S have limits on file descriptors, pipes, etc. I would check that. Second, broken pipes happen when one side closes when there is still action. In Unix C it is easy to do – if you use a piped open but you only want to get the first line of data so your read from the pipe and close … you get a broken pipe every time. This is harmless if that is what you want. Death if not. You might check your Oracle code for premature closing as I doubt it is stunnel. Can you trap the error and resume and see if it works? It well could. Essentially what I am saying is this is not directly a stunnel problem, more likely it is an implementation error. Which could be in the Oracle code as I have had problems with it in the past. More information on the O/S and the Oracle code would help.

Windows Server 2003 issues with stunnel, TLS 1.2 on website(s)
by Sean Kelley 27 Feb '20

27 Feb '20

*Issue:* Old Windows Server cannot be upgraded, but needs TLS 1.2 encryption. Stunnel looks like a solution, but I'm having issues configuring it to work (It is "running" successfully with a pem file and port 442). In IIS Manager btw, the website SSL Port is set to 443. I've tried searching (i.e. google "site: https://www.stunnel.org/pipermail/stunnel-users/ server 2003") and have found a few leads, but nothing that addresses my issues in a way I understand. My ignorance I'm sure. *Server details:* * Windows Server 2003, Standard Edition, Service Pack 2 * IIS web server running 3 websites (ASP, PHP mix) * Valid Certificates from Lets Encrypt in Certificate Store * stunnel 5.49 (latest version I could find that works on 32bit OS's) sorry it's not the latest :( *Working Log with Port 442:* 2020.02.24 15:24:37 LOG7[main]: Running on Windows 5.2 2020.02.24 15:24:37 LOG7[main]: No limit detected for the number of clients 2020.02.24 15:24:37 LOG5[main]: stunnel 5.49 on x86-pc-msvc-1500 platform 2020.02.24 15:24:37 LOG5[main]: Compiled/running with OpenSSL 1.0.2p-fips 14 Aug 2018 2020.02.24 15:24:37 LOG5[main]: Threading:WIN32 Sockets:SELECT,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI 2020.02.24 15:24:37 LOG7[main]: errno: (*_errno()) 2020.02.24 15:24:37 LOG7[ui]: GUI message loop initialized 2020.02.24 15:24:37 LOG7[main]: Running on Windows 5.2 2020.02.24 15:24:37 LOG5[main]: Reading configuration from file stunnel.conf 2020.02.24 15:24:37 LOG5[main]: UTF-8 byte order mark detected 2020.02.24 15:24:37 LOG5[main]: FIPS mode disabled 2020.02.24 15:24:37 LOG7[main]: Compression disabled 2020.02.24 15:24:37 LOG7[main]: No PRNG seeding was required 2020.02.24 15:24:37 LOG6[main]: Initializing service [https] 2020.02.24 15:24:37 LOG7[main]: Ciphers: HIGH:!aNULL:!SSLv2:!DH:!kDHEPSK 2020.02.24 15:24:37 LOG7[main]: TLS options: 0x03004004 (+0x00004000, -0x00000000) 2020.02.24 15:24:37 LOG6[main]: Loading certificate from file: C:\Program Files\stunnel\config\mywebsite.pem 2020.02.24 15:24:37 LOG6[main]: Certificate loaded from file: C:\Program Files\stunnel\config\mywebsite.pem 2020.02.24 15:24:37 LOG6[main]: Loading private key from file: C:\Program Files\stunnel\config\mywebsite.pem 2020.02.24 15:24:37 LOG6[main]: Private key loaded from file: C:\Program Files\stunnel\config\mywebsite.pem 2020.02.24 15:24:37 LOG7[main]: Private key check succeeded 2020.02.24 15:24:37 LOG7[main]: ECDH initialization 2020.02.24 15:24:37 LOG7[main]: ECDH initialized with curve prime256v1 2020.02.24 15:24:37 LOG6[main]: Initializing service [domain] 2020.02.24 15:24:37 LOG7[main]: Ciphers: HIGH:!aNULL:!SSLv2:!DH:!kDHEPSK 2020.02.24 15:24:37 LOG7[main]: TLS options: 0x03014004 (+0x00014000, -0x00000000) 2020.02.24 15:24:37 LOG6[main]: Loading certificate from file: C:\Program Files\stunnel\config\mywebsite.pem 2020.02.24 15:24:37 LOG6[main]: Certificate loaded from file: C:\Program Files\stunnel\config\mywebsite.pem 2020.02.24 15:24:37 LOG6[main]: Loading private key from file: C:\Program Files\stunnel\config\mywebsite.pem 2020.02.24 15:24:37 LOG6[main]: Private key loaded from file: C:\Program Files\stunnel\config\mywebsite.pem 2020.02.24 15:24:37 LOG7[main]: Private key check succeeded 2020.02.24 15:24:37 LOG7[main]: ECDH initialization 2020.02.24 15:24:37 LOG7[main]: ECDH initialized with curve prime256v1 2020.02.24 15:24:37 LOG5[main]: Configuration successful 2020.02.24 15:24:37 LOG7[main]: Binding service [https] 2020.02.24 15:24:37 LOG7[main]: Listening file descriptor created (FD=292) 2020.02.24 15:24:38 LOG7[main]: Setting accept socket options (FD=292) 2020.02.24 15:24:38 LOG6[main]: Service [https] (FD=292) bound to 10.0.1.11:442 2020.02.24 15:24:38 LOG7[main]: Skipped SNI slave service [domain] 2020.02.24 15:24:38 LOG7[cron]: Cron thread initialized 2020.02.24 15:25:38 LOG6[cron]: Executing cron jobs 2020.02.24 15:25:38 LOG6[cron]: Cron jobs completed in 0 seconds 2020.02.24 15:25:38 LOG7[cron]: Waiting 86400 seconds *Log Error with port 443:* Binding service [https] to 10.0.1.11:443: Permission denied (WSAEACCES) (10013)* * *Conf:* ; Debugging stuff (may be useful for troubleshooting) debug = 7 ;output = stunnel.log ; TLS front-end to a web server [https] ; doesn't work with 443 below, works with 442 accept = 10.0.1.11:442 connect = 80 cert = C:\Program Files\stunnel\config\mywebsite.pem ; "TIMEOUTclose = 0" is a workaround for a design flaw in Microsoft SChannel ; Microsoft implementations do not use TLS close-notify alert and thus they ; are vulnerable to truncation attacks TIMEOUTclose = 0 [domain] sni = https:mywebsite.com sni = https:www.mywebsite.com cert = C:\Program Files\stunnel\config\mywebsite.pem ; connect = 80 connect = localhost:80 client = no sslVersion = TLSv1.2 -------------- Thanks, Sean

How to use SNI
by Paul Coshott 17 Feb '20

17 Feb '20

Hi Everyone, I have a single domain on my internet server, but it has 3 sub-domains. A separate web app runs off each one, but I need all 3 to be secured with https. I have the ssl certificates I need, but I don't know how to format the SNI section for all 3 sub-domains. The 3 domains and ports I need are : app1.pcapps.one:449 -> 127.0.0.1:8080 app2.pcapps.one:450 -> 127.0.0.1:81 app3.pcapps.one:451 -> 127.0.0.1:82 each domain has a certificate such as : cert = C:\httpscert\app1.pcapps.one.pfx Can anyone tell me how to write out the SNI section to get this working? Thanks, Paul

How to pass URL parameters in connect to
by Shashank Shekhar 14 Feb '20

14 Feb '20

Hi, I am evaluating stunnel for a project. I want to translate a HTTP call to HTTPS. When I specify the URL to send to in the config file, I get error ""Unknown TCP service "443/api/path""". My config is as below: [https] client = yes accept = 4433 connect = myurl.com:443/api/path When I try the same thing without the sub-paths "/api/path" the connection works, but of course it doesn't hit the URL I want to hit. How do I achieve this? I tried going through the documentation, but couldn't figure it out. Any help will be greatly appreciated. Thank you, Shashank
