by David Tedjo 30 Jun '15

30 Jun '15

Hi everybody, i bought an Logitech keyboard with display. I use now stunnel to bring my email account to my display. Logitech got a applet for this. Now i can use it but i got a problem with the unread mails. My display shows me 6 unread messages, but thats all my messages in my in-box and i read it already. Is this a problem of stunnel or a problem in the software of the keyboard? Best Regards David

Re: [stunnel-users] installing stunnel on Mac Machine

1. I’m an stunnel newbie. 2. I thought I would give the Mac install script a try: downloaded it to ~/Documents, did the chmod, and ran script; looks like it can’t create/find the config file? Is that something I need to do manually? WDDMBPW80336XHAGV:Documents williamdockery$ ./stunnel-5.20b8-osx [ ] Cron started [ ] Clients allowed=125 [.] stunnel 5.20 on x86_64-apple-darwin14.3.0 platform [.] Compiled/running with OpenSSL 0.9.8zd 8 Jan 2015 [.] Threading:PTHREAD Sockets:SELECT,IPv6 TLS:ENGINE,OCSP [ ] errno: (*__error()) [.] Reading configuration from file /etc/stunnel/stunnel.conf [!] Cannot open configuration file [.] [.] Syntax: [.] stunnel [<filename>] ] -fd <n> | -help | -version | -sockets [.] <filename> - use specified config file [.] -fd <n> - read the config file from a file descriptor [.] -help - get config file help [.] -version - display version and defaults [.] -sockets - display default socket options Thoughts?

Hi, Is there an MSI installer available for Stunnel version 5.19 ? If so, has anyone tried to call the stunnel MSI installer from an Install shield installer?

Re: [stunnel-users] stunnel 5.18 may keep high CPU usage
by Dod 22 Jun '15

Hello Michal, Same problem with 5.19b4 and nothing special in the logs. Now I know how to reproduce the problem instantly, I just have to put my computer in StanBy mode and Awake it. Using Process Explorer from Sysinternals I see that stunnel produce a permanent "Other I/O" flow when problem appear. I/O Other : "The rate at which the process is issuing bytes to I/O operations that do not involve data such as control operations. This counter counts all I/O activity generated by the process to include file, network and device I/Os." OtherI/O is confirmed by Process Monitor that trace no File nor Registry nor Network activity. But as stunnel still respond correctly to a Quit menu or any other menus and SSL requests I assumed that it may be some Thread going crazy so I compared running thread between normal stunnel behavior with the 25% CPU behavior and found that in fact there is a thread that do no terminate correctly. Here is the Thread's stack : MSVCR90.dll!_endThread+0x7d ntoskrnl.exe!memset+0x61a ntoskrnl.exe!KeWaitForMultipleObjects+0xd52 ntoskrnl.exe!KeWaitForSingleObject+0x19f ntoskrnl.exe!PoStartNextPowerIrp+0xba4 ntoskrnl.exe!PoStartNextPowerIrp+0x1821 ntoskrnl.exe!PoStartNextPowerIrp+0x1a97 ntoskrnl.exe!KeReleaseInStackQueuedSpinLock+0x5a afd.sys+0x61c1c afd.sys+0x51d3b ntoskrnl.exe!NtMapViewOfSection+0x15b7 ntoskrnl.exe!NtDeviceIoControlFile+0x56 ntoskrnl.exe!KeSynchronizeExecution+0x3a23 wow64cpu.dll!TurboDispatchJumpAddressEnd+0x6c0 wow64cpu.dll!TurboDispatchJumpAddressEnd+0x1fb wow64.dll!Wow64SystemServiceEx+0x1ce wow64.dll!Wow64LdrpInitialize+0x42a ntdll.dll!RtlIsDosDeviceName_U+0x1f5c4 ntdll.dll!LdrInitializeThunk+0xe ntdll.dll!NtDeviceIoControlFile+0x15 WS2_32.dll!select+0x9f stunnel.exe!OPENSSL_Applink+0xd3ec stunnel.exe!OPENSSL_Applink+0x961 Hope it help... regards.

Generate CONNECT
by reiner otto 22 Jun '15

22 Jun '15

I have following problem: I want to avoid the user to explicitly specify a https-proxy in his browser. Let me explain: For http, a transparent proxy can be interfaced via iptables DNAT, for example.Same for https will not work, without certificates installed etc.However, I only want some basic info about the https-session, like traffic volume or destination domain. In case, there is an explicit https-proxy defined in the browser, I can get this info from the connect request, preceding the secure data exchange.But I want to avoid this explicit declararion. Most likely I will need some custom programming for this, but may be there is a specialist here to give some direction.

Default Ciphers
by Clayton Keller 17 Jun '15

17 Jun '15

Looking at the Changelog I see the following from the 5.15 info: "MEDIUM ciphers (currently SEED and RC4) are removed from the default cipher list." And this from the 5.00 info: "Default "ciphers" updated to "HIGH:MEDIUM:+3DES:+DH:!aNULL:!SSLv2" due to AlFBPPS attack and bad performance of DH ciphersuites." Given these to comments would it be accurate to say that the current default "ciphers" value is: "HIGH:+3DES:+DH:!aNULL:!SSLv2" Also, some of the docs indicate what the default value currently is. Is there an easier way to determine that value via CLI or other means? Thanks Clay
