running stunnel from inetd
by Guylhem 21 Mar '12

21 Mar '12

Hello To follow up on my test, I would like to try and run stunnel from inetd However I wonder if anyone has an experience, suggestions, and some inetd.conf examples. I read it was possible in the FAQ but I didn't see a lot of examples Should I use a configuration file (for the global parameters) then specify connect= params? ex : 443 stream tcp6 nowait nobody /sbin/stunnel /etc/stunnel.conf connect=127.0.0.1:80 TIMEOUTclose=0 Thanks Guylhem

question about Ephemeral Diffie-Hellman
by Guylhem 21 Mar '12

Hello I've read that EDH calculations were ca cause of significant slow up on http://matt.io/technobabble/hivemind_devops_alert:_nginx_does_not_suck_at_s… I'm running stunnel on a embedded Linux/MIPS, where I'm trying to light up the load. Is it possible to disable EDH? If so, how? I couldn't find any info on that. Thanks Guylhem

Hello, I use Stunnel with Windows. The configuration file "stunnel.conf" and the log file "stunnel.log" are in the %USERAPPDATA%\Stunnel folder. Stunnel starts and works without problems. But the GUI options "Edit stunnel.conf" and "Reload stunnel.conf" do not work. Is remedy possible? Sebastian

I have found the stunnel version on PCB : stunnel 4.35 on x86_64-pc-linux-gnu with OpenSSL 1.0.0e 6 Sep 2011 the version on PCA is 4.52 this is perhaps a too big difference isn't it ? Best Philippe

Re: [stunnel-users] issue with running stunnel
by Thomas Eifert 18 Mar '12

Hi again Dewen; It sounds to me like Stunnel isn't being accessed at all. You should be seeing something in the Stunnel log window. I run Stunnel under Windows, so what I generally do is get Stunnel to listen to the loopback interface at address 127.0.0.1, or some other address within the loopback interface range. As such, if I was attempting to access it with a utility like Netcat, my basic stunnel.conf would look something like this for the client side: debug =7 [service.name] client = yes accept = 127.0.0.1:12035 connect = destination.address:1230 Then, I would point Netcat to the listening address and port. In your case, that might be netcat 127.0.0.1:12035. Then see if Stunnel logs your connection attempt. Again, this is under Windows, so your mileage may vary. Let us know how it works out for you.

Stunnel 1.45 on Win7 x64, OCSP blows up
by Michael Olson 16 Mar '12

16 Mar '12

I'm using stunnel in client mode on a Windows 7 x64 workstation, installed using ftp://ftp.stunnel.org/stunnel/stunnel-4.52-installer.exe Everything works until I try to check the server certificate for revocation using an OCSP server, at which point stunnel crashes whenever I make a connection. The following error pops up in a dialog box: OPENSSL_Uplink(0FBE5000,14): no OPENSSL_Applink My config is pretty simple: -------------------------------------------------------------- debug = 7 # I do want FIPS enabled, but I figured one problem at a time. fips = no CAfile = ca-bundle.crt verify = 2 OCSP = http://ocsp.test.net/ options = NO_SSLv2 [test1] client = yes accept = 127.0.0.1:80 connect = web.test.net:443 -------------------------------------------------------------- The log gets as far as: 2012.03.02 11:07:41 LOG7[4296:5008]: OCSP: server connected when it crashes. -- Mike
