Issues after upgrading stunnel to v5.51 on Windows
by stunnel＠alpiston.com 08 Apr '19

08 Apr '19

Hello, I've been using stunnel v5.50 (x64-pc-mingw32-gnu) to encrypt RTSP traffic between two Win10 Pro computers without any problems. However, after upgrading to stunnel v5.51 the RTSP traffic has started to stutter (as the framerate has dropped to almost nothing, from 20 fps to 0.01 fps to be precise), and the few frames that are actually transferred arrive visually corrupted. After enabling debugging at level 7, I get the following (some parts have been obfuscated for privacy reasons): 2019.04.08 00:53:51 LOG7[main]: Found 1 ready file descriptor(s) 2019.04.08 00:53:51

Stunnel 5.51 Pop3 Problem?
by Colin 07 Apr '19

07 Apr '19

Hello, I'm new to this list and looking for advice/help with release 5.51 for Windows. I have three accounts, Yahoo, Aol and Gmx and I use Foxmail 5 with Stunnel. I use pop3 with all accounts and sometimes when retrieving mail I may decide to 'Not Fetch' any mail on the server that looks 'iffy' untill I've looked at it via the mail providers website. Now I've just upgraded to version 5.51 (over 5.50) and when checking any of the said accounts I can't see any mail that hasn't been fetched (the server looks empty.) But if I login to the mail website the unfetched mail is there to view for all accounts. I reverted to version 5.50 and now I can see the unfetched mail for all accounts in my 3rd party software. Therefore my question is: Is there a problem (bug??) with 5.51 which stops me from seeing unfetched pop3 mail or do I have to add something to the config file to make it work properly? Thanks...Colin

Re: [stunnel-users] V5.51 no support for OpenSSL 1.0.2 ?

Is there a Win32 installer that supports sslVersionMin = TLS1.2?
by kent loving 01 Apr '19

01 Apr '19

I need to run a client on Win XP that connects to a server using TLS 1.2 or higher. Jose Alf posted that he made a test build of 5.50 in a win32 installer but uses OpenSSL 1.0.2p. And it does not seem to be official. The changelog says version 5.49, which has a win32 installer, also uses OpenSSL 1.0.2p. I can't tell if it supports TLS1.2. The man page implies I need OpenSSL 1.1.1 to get the sslVersionMin option. And, OpenSSL says v1.0.2 support ends in 9 months. Any advice is appreciated. Thanks, Kent Loving

OpenVPN with stunnel

ERR_SSL_VERSION_INTERFERENCE on Google Chrome v 73.0.3683.86 and stunnel v5.51b1
by Kolan Koala 25 Mar '19

25 Mar '19

I cannot get TLS 1.3 to work with Chrome. TLS 1.3 works fine in firefox quantum v 66.0.1 over the same hardware, so this is not caused by middleboxes. It is a fault with stunnel or Chrome. ERR_SSL_VERSION_INTERFERENCE error occurs in Chrome and will not connect. For now the solution is to turn off TLS v1.3 in stunnel configuration and force TLS v1.2, but this is not a long term solution. Does anyone have a solution to use TLS 1.3 with chrome and stunnel together? Kolan

No more Win32 stunnel?
by John Hall 21 Mar '19

21 Mar '19

I've only just discovered that stunnel is seemingly no longer being updated for Win32; at any rate there has been no version 5.50 released for Win32. It would have been nice if there had been an announcement to that effect, as until now I was only subscribed to the announcements mailing list and had thus been in blissful ignorance. (For some reason I never saw ANY announcement for 5.50 - in fact I still seem to be on 5.47.) Given that there are a number of ports to different OSs by various people, is there any chance that someone might supply a Win32 port for future versions? (Sadly I lack the knowledge to do that myself.) -- John Hall

Verify peer immediately
by Phillip Hellewell 21 Mar '19

21 Mar '19

Hi, I have verifyPeer = yes in my client stunnel.conf. Is there any way to make it verify the peer right away instead of waiting until a connection is made (to the accept port)? I run stunnel with foreground = yes and would like it to exit right away if the peer doesn't have the appropriate cert/key. Thanks, Phillip

Hi, I have to create tunnel between server and client. Client have proxy configured in between. So i use below in /etc/stunnel/stunnel.config pid = /var/run/stunnel.pid cert = /home/client.crt key = /home/client.key options = NO_SSLv2 debug = 7 output = /var/log/stunnel4/stunnel.log client = yes CAfile=/home/**chain.pem verify=2 [test] protocol = connect accept = 127.0.0.1:10000 protocolHost = server.xxxx.com:443 connect = <PROXYIP>:<PROXY port> protocolUsername = user1 protocolPassword = password protocolAuthentication = Basic then i bring up the service. With above configuration connection works file. Now i don't want proxy password to be clear text in this case. Any pointers plz Thanks, Vj
