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

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

Wondering if process to create the g2.pem file is available?

Was wondering if the process to create the g2.pem file you shared is available. It does work with changes to the stunnel.conf file for both the smtp1.guam.net and mail.guam.net [guampop] client=yes accept = 127.0.0.1:20996 connect = mail.guam.net:995 debug = 7 verifyChain = yes CApath = /etc/ssl/certs CAfile = /etc/stunnel/g2.pem checkHost = mail.guam.net OCSPaia = yes [guamsmtp] client=yes accept = 127.0.0.1:20466 connect = smtp1.guam.net:465 debug = 7 verifyChain = yes CApath = /etc/ssl/certs CAfile = /etc/stunnel/g2.pem checkHost = smtp1.guam.net OCSPaia = yes Not sure the the g2.pem would work for all time, or has an expiration date.

stunnel doesn't allow two client certificates with the same Subject DN?
by Christopher Schultz 16 Apr '24

16 Apr '24

Hello, I was recently rotating a certificate for a service and I went through my usual procedure: 1. Generate a new client key+cert; don't place them into service, yet 2. Distribute the new certificate to all my stunnel servers that need to trust it by placing it at the end of each of my servers' CAFile files 3. Restart all stunnel services 4. Swap the old key+cert for the client with the new key+cert 5. Test that all is well I've found that if the Distinguished Name of both the old and new certificate are the same, stunnel will only trust the one that is mentioned /first/ in the CAFile. For example, if the CAFile contains: -----BEGIN CERTIFICATE----- certificate A Serial Number: 12345678 Subject: C=US, OU=Testing, O=Example.com, CN=test -----BEGIN CERTIFICATE----- -----BEGIN CERTIFICATE----- certificate B Serial Number: 87654321 Subject: C=US, OU=Testing, O=Example.com, CN=test -----BEGIN CERTIFICATE----- Certificate A will be trusted but Certificate B will not be trusted. The error shown in the logs is: CERT: Pre-verification error: self signed certificate Apr 15 21:33:06 mirth-pcc.chadis.com stunnel[23421]: Certificate check failed: depth=0, /C=US/OU=Testing/O=Example.com/CN=test While the certificates are both self-signed, that should not cause an error. Removing the old certificate from the CAFile or moving it to the bottom of the file resolves the problem. (But of course then Certificate A is no longer trusted despite it appearing in the CAFile.) Is this expected behavior? It would be very helpful if stunnel could support two different certificates with the same Subject DN for these kinds of cert-rotation processes. The alternatives are to always use a new DN each time or to add/remove at the same time which makes rolling-back more difficult. Note that everything else about these certificates is different: serial number, fingerprint, generating-key, etc. It's only the Subject DN that is the same. This is stunnel 4.56 on x86_64-koji-linux-gnu platform, on Amazon Linux 2. Thanks! -chris

Received trusted client CA list not found
by allmail 16 Mar '24

16 Mar '24

I see this message in the Stunnel (client) logs during SSL handshake with the server The server requires a client certificate which has been configured in the stunnel configuration. The handshake is working fine but I was wondering what exactly does this line mean. From what I found so far, seems like there is a way for the server to specify which CA's it will accept for the client certificate and it can specify them in the ClientCertificate request that it sends This server doesnt send anything like that, so I am guessing that is the reason for this log line? Can someone please confirm? Btw, I see this line only when using TLSv1.3. When I restrict the client to TLSv1.2, I dont see this line. thanks LOG Peer certificate required TLS state (connect): before SSL initialization Initializing application specific data for session authenticated TLS state (connect): SSLv3/TLS write client hello TLS state (connect): SSLv3/TLS write client hello TLS state (connect): SSLv3/TLS read server hello TLS state (connect): TLSv1.3 read encrypted extensions Received trusted client CA list not found TLS state (connect): SSLv3/TLS read server certificate request

Stunnel HA Options
by caspernetherlands＠gmail.com 07 Mar '24

07 Mar '24

Hello folks, I have seen a couple of other posts concerning this question but I am still unclear and wanted to see if there are any new options for 2024. What would the recommended setup for Stunnel look like for HA (high-availability)? All I need is basically to have two servers, one active and another one stand by and be able to fail over to the standby server when the active one becomes unavailable due to hardware failure, bad vmotion etc. Extra point if this setup offers automatic failover to DR as well, meaning failover to a third server that's also on standby in case of catastrophic failures on the first two. This almost looks like a load-balancing solution but not really. I say this because I tried to leverage F5 to accomplish this HA scenario and wasn't successful at it because of the way that the F5 performs active checks so often and how noisy that can be for network perimeter security setups. My main request is the local HA though, I can come up with a solution for DR later on. Any recommendation is appreciated. Thank you in advance!

possible typo in manpage imap example
by alisonatwork＠outlook.com 05 Mar '24

05 Mar '24

Hi, It's possible that I am missing something obvious, but I was reading the manpage today and it seems like the example suggesting how to configure an email client for tunneled imap is incorrect. It suggests that the user configure their client to connect to port 119, but then the example stunnel config shows accept = 143. If this is indeed incorrect, I think the following files need to be modified to change 119 to 143: doc/stunnel.8.in doc/stunnel.html.in doc/stunnel.pl.8.in doc/stunnel.pl.html.in doc/stunnel.pl.pod.in doc/stunnel.pod.in Regards, Alison

Introduction: In the dynamic landscape of education, the demand for online courses has witnessed an unprecedented surge, especially in fields like nursing. The flexibility and accessibility offered by online learning platforms have made education more attainable for individuals balancing work, family, and other commitments nurs fpx 4050 assessment 2. However, the rigorous nature of nursing programs can pose challenges for students, leading many to seek assistance with their coursework. In this blog, we will explore the growing trend of students turning to online course help and paying someone to do their online classes, particularly in the realm of nursing paper writing services. The Rise of Online Nursing Education: The allure of online nursing education lies in its flexibility, allowing aspiring nurses to pursue their dreams without sacrificing their current commitments. With the increasing popularity of online nursing programs, students are presented with a unique set of challenges. Balancing clinical experiences, theoretical coursework, and other responsibilities can be overwhelming, prompting students to explore options for additional support. The Need for Academic Assistance: Nursing programs often require students to delve into complex topics, complete extensive research, and submit well-crafted papers. The pressure to excel in both practical and theoretical aspects of nursing education can be daunting, leading some students to seek online course help. The question then arises – is it ethical to pay someone to do my online class or assist with nursing paper writing services? Understanding the Ethical Dilemma: The ethical considerations surrounding seeking academic assistance are complex. On one hand, students argue that external support enables them to focus on practical experiences and hands-on learning. On the other hand, critics argue that outsourcing coursework undermines the integrity of education and the development of essential skills nurs-fpx 4060 assessment 1. Navigating the Online Course Help Landscape: For those considering online course help, it is crucial to approach the situation with caution and a clear understanding of the ethical implications. Many online platforms and services claim to provide assistance with nursing paper writing services, but it is essential to discern between legitimate support and services that may compromise academic integrity. Choosing Reputable Services: When seeking online course help for nursing paper writing services, it is imperative to choose reputable and ethical service providers. These services should prioritize academic honesty, transparency, and the development of students' critical thinking skills. Thoroughly researching and vetting potential service providers can help students make informed decisions. The Role of Academic Support Services: Rather than viewing online course help as a shortcut, students should consider these services as valuable supplements to their learning journey. Academic support services can offer guidance, feedback, and assistance in understanding complex nursing concepts. This collaborative approach allows students to enhance their skills while meeting the demands of their coursework chamberlain nurse executive track. Developing Essential Skills: While online course help can provide support, it is essential for students to actively engage with the material and develop the critical skills necessary for a successful nursing career. Ethical academic support services aim to empower students, encouraging them to take an active role in their education and fostering a sense of responsibility for their learning outcomes. Balancing Priorities: The decision to seek online course help should be accompanied by a realistic assessment of one's priorities and capabilities. Nursing students juggling multiple responsibilities may find that strategic use of academic support services can help them maintain a healthy work-life balance while excelling in their coursework. The Impact on Future Nursing Practice: Aspiring nurses must recognize that the skills and knowledge acquired during their education directly impact their ability to provide quality patient care in the future. While online course help can provide temporary relief, it is crucial for students to actively engage with the material and strive for a deep understanding of nursing concepts. Conclusion: The landscape of nursing education is evolving, with online courses offering unprecedented flexibility for students. As the demand for nursing professionals continues to grow, the need for academic support services, including nursing paper writing services, is likely to persist online class help. However, students must approach online course help with a balanced perspective, understanding the ethical considerations and prioritizing the development of essential skills. By navigating the online course help landscape responsibly, nursing students can enhance their learning experience and prepare for a successful and fulfilling career in healthcare.

older browsers, stunnel and privoxy
by kovacs janos 04 Mar '24

sorry to bother, im trying to make older browsers be able to display TLS 1.1 and TLS 1.2 sites. i heard stunnel cant be configured to always forward to the current site address dynamically, thats why i would use privoxy. the browser is configured to send to: 127.0.0.1 443 stunnel config has this at the end: [Tunnel_in] client = yes accept = 127.0.0.1:443 connect = 127.0.0.1:8118 verifyChain = yes CAfile = ca-certs.pem checkHost = localhost 127.0.0.1:8118 is the privoxy address. this is what stunnel writes: LOG5[main]: Configuration successful LOG5[0]: Service [Tunnel_in] accepted connection from 127.0.0.1:3261 LOG5[0]: s_connect: connected 127.0.0.1:8118 LOG5[0]: Service [Tunnel_in] connected remote server from 127.0.0.1:3262 and the browser infinitely loads, and never loads anything or leaves the page. if i remove the last 3 lines, its the same just with this line added: LOG4[main]: Service [Tunnel_in] needs authentication to prevent MITM attacks but it doesnt give an error or anything. with a configuration like: [Tunnel_out] client = no accept = 127.0.0.1:443 connect = 127.0.0.1:8118 cert = stunnel.pem this is what it gives: LOG5[3]: Service [Tunnel_out] accepted connection from 127.0.0.1:3294 LOG3[3]: SSL_accept: 1407609B: error:1407609B:SSL routines:SSL23_GET_CLIENT_HELLO:https proxy request LOG5[3]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket and browser gives a server not found error immediately. im not even sure if i should use client or server configuration in a case like this, but none of them works anyway. all i would need is for my browser to get the pages decrypted, or at least in less than TLS1.1. like how on newipnow.com i can access sites with any encryption, since they are sent to the browser without encryption. the browser just gives an "unencrypted tunnel" warning, which is how i found stunnel, and which is exactly what i need, just locally.

Windows 2022 tunnel client issues
by Mark Weishaar 23 Feb '24

23 Feb '24

Hello, I’m working on replacing an older Windows server that uses stunnel 5.71 to connect to an Oracle database running on a Linux box. I can communicate just fine with the older Windows machine and another Linux box; however, when I try to connect with the stunnel 5.72 on the Windows 2022 server, I keep running into issues and the connection is forcibly closed. Old Windows server: stunnel 5.71 New Windows 2022 server: stunnel 5.72 (I also tried 5.71 and 5.62 just to rule things out Oracle db server: stunnel 5.72 Other Linux server: stunnel 5.72 My stunnel.conf file is very basic, but this is what is working from my other Windows server (running stunnel 5.71): debug = 7 [oracle15211] client = yes accept = 127.0.0.1:15211 connect = 172.28.125.52:15211 Below is the log with debug level 7… the only issue that I’m seeing is the “transfer() loop executes not transferring any data” message that baffles me but I’m not sure if that’s
