linux default installation
by John A. Wallace 29 Feb '12

29 Feb '12

Hello. I am comparing a default installation of "stunnel.conf" in Linux with that in Windows, and I found some differences that I have a couple questions about. The Windows installation installed in client mode by default, but the one for Linux in server mode. I made a backup copy of the default files for both. For now I want to run stunnel in Linux in client mode, so I am making some changes to it. The installed default for these six parameters are as follows: Client=no Chroot=/var/lib/stunnel/ Setuid=stunnel Setgid=nogroup Pid=/var/run/stunnel.pid Cert=/etc/stunnel/stunnel.pem Is it correct to change these settings for testing in client mode so that they match the current Windows' client mode configuration, like so: Client=yes #Chroot=/var/lib/stunnel/ #Setuid=stunnel #Setgid=nogroup #Pid=/var/run/stunnel.pid #Cert=/etc/stunnel/stunnel.pem

stunnel log delayed
by John A. Wallace 29 Feb '12

29 Feb '12

Hello, I am running stunnel on Linux in client mode, and I have the following setting in "stunnel.conf": output=stunnel.log The log does not get written to periodically while the program is running but is delayed until after I have closed the program. It would be helpful to be able to look at it from time to time, especially while troubleshooting. Any way "to push" the data down into the file sooner? Thanks. John

Memory allocated in a different thread at network.c, line 63
by Philippe A. 29 Feb '12

29 Feb '12

Hello, I find the following error my syslog when stopping stunnel 4.52. The program seems to be unable to shutdown cleanly (ex: pid file doesn`t get removed). stunnel: INTERNAL ERROR: Memory allocated in a different thread at network.c, line 63 This is how I configured: LDFLAGS=-Wl,-rpath,/usr/local/app/openssl/lib64 \ ./configure --prefix=/usr/local/app/stunnel \ --includedir=$PKG_HOME/openssl/include/ \ --with-ssl=$PKG_HOME/openssl/ \ --with-threads=fork \ --disable-libwrap Where PKG_HOME is a variable of my own. I had the same error with version 4.51. I do not see the error when running in foreground. I do not see the error either if I compile with threads instead of fork. In case this information is needed, this is how I configured openssl. ./config --prefix=/usr/local/app/openssl --libdir=lib64 shared zlib-dynamic no-ssl2 This is on RHEL 5.5 Regards.

SSLv3 on Win32 does not work
by Zdenek Valach (INBOX) 25 Feb '12

25 Feb '12

Hi I am using the latest version of stunnel in server mode (converting POP3S to POP3) I need to make service work in SSLv3 mode. In TLSv1 it works fine, when I add to stunnel.conf tag sslVersion = all, it still works fine, but when I use sslVersion = SSLv3 although config file is loaded properly, process EXE crashed during establishing the connection. It looks like some bug in actual version of stunnel. Does somebody experience same problem? Thank you very much in advance for any advice Thanks Zdenek ____________________________________________________________ Send any screenshot to your friends in seconds...

Hi! I have downloaded the Android port of stunnel: http://mirrors.zerg.biz/stunnel/stunnel-4.52-android.zip I would like to use it on my Android tablet but I don't know how to start or use it. I have root access on the device. I placed the stunnel and openssl files into /data/stunnel/ directory. Both files have execute permission. Can anybody please provide some information on how to use this application? I haven't found any info on stunnel.org. Best Regards, Balázs Huzella

Multiple Domains for https
by Thomas Manson 23 Feb '12

23 Feb '12

Hi, I want to setup the following architecture : stunnel ---> haproxy --> 2 webserver. I run severa virtual host on the 2 webservers, and a subset of them needs https. I can allocate several IP address for the host that run stunnel. How do I configure a single stunnel process to have a certificate per IP for the port https? I tryed to add several section like the following : [mansonthomas.com] cert = /etc/stunnel/sites/mansonthomas.com/mansonthomas.com.crt accept = 88.190.17.222:443 connect = 127.0.0.1:82 xforwardedfor = yes TIMEOUTclose = 0 So the question is : Is it possible ? do you have a sample configuration file to share for this use case? Thanks, Thomas.

:o( Stunnel KO on Windows Server 2003 VM
by BOXI31 TEST 22 Feb '12

22 Feb '12

Hi all ! I'm new with Stunnel. It'a nice tool that works perfectly on Windows 7 64-bit host but won't start on Windows Server 2003 guest VM (VMWare Player 3.1.x). When I try to start it, I have a message like "can't initialize...". I'll give you the exact message tomorrow, I don't have now the VM on hand. On Windows 7, when I started Stunnel for the 1st time, I was asked to create a certificate with a kind of wizard but on the Windows Server 2003 VM, it stops before this step. Is it a known problem on VM ? What could I check ? I managed to make the software I'm testing (SMTP sending function) on the VM "talk" to Stunnel on my host by I'd really like to install it on the VM to be independant from host. Thanks by advance, Regards, Steve.

Stunnel Not supporting DSA key
by Anand Krishnan 16 Feb '12

16 Feb '12

Hi All, I have query regarding Stunnel (version 4) working. We have a windows client application which communicates with a web service via SSL encryption with DSA algorithm. The windows client machine is using a pfx file for authentication with server. Now we need to convert this windows machine with a linux machine and hence we converted the pfx into pem file. But when i tried to start the Stunnel using this pem file it threws up below error. 2012.02.13 18:23:23 LOG3[23972:47049761923264]: error stack: 140B3009 : error:140B3009:SSL routines:SSL_CTX_use_RSAPrivateKey_file:PEM lib 2012.02.13 18:23:23 LOG3[23972:47049761923264]: SSL_CTX_use_RSAPrivateKey_file: 607907F: error:0607907F:digital envelope routines:EVP_PKEY_get1_RSA:expecting an rsa key It seems the .pem file I mapped in the stunnel.conf is expecting RSA algorithm but when I opened it I can see it as DSA coded. Can some body help me on this. I am attaching the pfx and pem file along with this.

Key files across NFS
by James Devine 16 Feb '12

16 Feb '12

I have an stunnel config saved on an NFS mount so it can be shared with other servers, it only seems to work if the key file is stored locally, as soon as I move the key onto the NFS mount I get the error: /disks/disk1/stunnel/certs/wildcard.key: Value too large for defined data type (75) Any idea why that might be and what I might do to fix it?
