Configuring the STunnel for a TCP Client
by Vivek Gupta 01 Oct '14

01 Oct '14

Hi I have installed STunnel version 5.xx and using a TCP client to connect with it but no success. My details are as follows: 1. Configuration of STunnel.conf verify = 3 CAfile = peer-LMAX-fix-tunnel-DEMO-MktData.pem [LMAX-fix-tunnel-DEMO-MktData] client = yes accept = 127.0.0.1:40003 connect = fix-md-ate.lmaxtrader.com:443 cert = stunnel.pem key = stunnel.pem socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 Certificate file stunnel.pem was generated by software itself. 2. I have written a TCP client as follows:Only part of code is given below *********************************************** // Resolve the server address and port iResult = getaddrinfo("127.0.0.1", 40003, NULL, &servinfo); // Attempt to connect to an address until one succeeds for(ptr=servinfo; ptr != NULL ;ptr=ptr->ai_next) { // Create a SOCKET for connecting to server ConnectSocket = socket(ptr->ai_family,ptr->ai_socktype,ptr-ai_protocol); // Connect to server. iResult = connect( ConnectSocket, ptr->ai_addr, (int)ptr->ai_addrlen); break; } // Send an initial buffer iResult = send( ConnectSocket, sendbuf, (int)strlen(sendbuf), 0 ); printf("Bytes Sent: %ld\n", iResult); // Receive until the peer closes the connection do { iResult = recv(ConnectSocket, recvbuf, recvbuflen, 0); if ( iResult > 0 ) printf("Bytes received: %d\n", iResult); else if ( iResult == 0 ) printf("Connection closed\n"); else printf("recv failed with error: %d\n", WSAGetLastError()); } while( iResult > 0 ); ******************************************************** Here I would like to tell you that I have used 127.0.0.1 and 40003 in getaddrinfo and same has been configured in conf file. Whenever I try to connect I am receiving iResult =0 from recv(). Could anybody please let me know is there anything wrong with my configuration and how to get resolve the current issue?

26 Sep '14

I have updated stunnel to version 5.04 on Windows 7 32 & 64 bit, Windows Server 2008R2, Windows Server 2012 and Windows Server 2012R2 and in no case does the icon appear. I explicitly set taskbar = yes in the configuration file. -- Carter Browne cbrowne(a)cbcs-usa.com

"Socket operation on non-socket" when trying to pass the configuration file as a file descriptor on OSX
by Guylhem 24 Sep '14

24 Sep '14

Hello I'm trying to pass the configuration file with option fd. However, I get the following errors when I do : echo my configuration | stunnel -fd 0 This is not related to echo since I get the same errors with: cat conf | stunnel -fd 0 stunnel is just filling my logs with : 2014-07-13 6:48:46.675 PM stunnel[1959]: LOG3[140735238959888]: local socket: Socket operation on non-socket (38) 2014-07-13 6:48:46.676 PM stunnel[1959]: LOG3[140735238959888]: local socket: Socket operation on non-socket (38) (...) stunnel ./conf works fine I found a reference to a bug that caused this same error message on OSX when run in inetd mode, but nothing else. Any help is appreciated I'm using stunnel 5.02 on x86_64-apple-darwin13.2.0 platform with the following in -sockets: Socket option defaults: Option Name | Accept | Local | Remote |OS default ----------------+----------+----------+----------+---------- SO_DEBUG | -- | -- | -- | no SO_DONTROUTE | -- | -- | -- | no SO_KEEPALIVE | -- | -- | -- | no SO_LINGER | -- | -- | -- | 0:0 SO_OOBINLINE | -- | -- | -- | no SO_RCVBUF | -- | -- | -- | 131072 SO_SNDBUF | -- | -- | -- | 131072 SO_RCVLOWAT | -- | -- | -- | 1 SO_SNDLOWAT | -- | -- | -- | 2048 SO_RCVTIMEO | -- | -- | -- | 0:0 SO_SNDTIMEO | -- | -- | -- | 0:0 SO_REUSEADDR | yes| -- | -- | no TCP_KEEPCNT | -- | -- | -- |write-only TCP_KEEPINTVL | -- | -- | -- |write-only IP_TOS | -- | -- | -- | 0 IP_TTL | -- | -- | -- | 64 TCP_NODELAY | -- | yes| yes| no My configuration is quite simple : I just echo CAfile=/path/to/file.pem verify = 3 fips = no options = NO_SSLv2 debug = 7 [test] client = yes accept = 127.0.0.1:4443 connect = remoteip:443

Stunnel as windows service doesn't start on restart.
by John Smith 24 Sep '14

24 Sep '14

Running stunnel 5.03 on Windows 2008 R2. Everything is installed and working fine. I can even start/stop the service no problem... (Pretty sure the service is set to start Automatically) When I reboot my server stunnel service shows as started but nothing gets logged and none of my connections work. Once I restart the service through service manager, everything works. So on startup it doesn't seem to run... This only happens if i reboot the machine. I also asked the same question here: http://serverfault.com/questions/627932/stunnel-as-windows-service-doesnt-s… Output of my logs proving it works. 2014.09.11 15:57:48 LOG5[1612]: stunnel 5.03 on x86-pc-msvc-1500 platform 2014.09.11 15:57:48 LOG5[1612]: Compiled/running with OpenSSL 1.0.1i-fips 6 Aug 2014 2014.09.11 15:57:48 LOG5[1612]: Threading:WIN32 Sockets:SELECT,IPv6 SSL:ENGINE,OCSP,FIPS 2014.09.11 15:57:48 LOG5[1612]: Reading configuration from file stunnel.conf 2014.09.11 15:57:48 LOG5[1612]: FIPS mode disabled 2014.09.11 15:57:49 LOG5[1612]: Configuration successful

Possible problem found in init script with 'dirty' config file
by F. J. Blanco 23 Sep '14

23 Sep '14

Hi there. Perhaps this is a foolishness, but it happens to me, triggering a great headache. I'm Debian (Wheezy) user, using stunnel 4.53-1.1. I copied the stunnel configuration from another machine for a simple LAN SMTP relay. When I tried to reload the script, I got this: # /etc/init.d/stunnel4 start > Reloading configuration SSL tunnels: /etc/init.d/stunnel4: 34: test: /var/lib/stunnel4/: unexpected operator A few hours laters, I discovered the problem was in config file, in the chroot parameter: chroot = /var/lib/stunnel4 Specifically, with a hide space at the end of the line: chroot = /var/lib/stunnel4[ ] In the init script, in the function get_pids(), this mistake caused that this checkout fails: --- if test -f $CHROOT/$PIDFILE; then cat $CHROOT/$PIDFILE fi --- 'cat /var/lib/stunnel4///stunnel.pid' is not the same as 'cat /var/lib/stunnel4/[ ]//stunnel.pid' Perhaps a suggestion, a little change here: CHROOT=`grep "^chroot" $file|sed "s;.*= *;;"` Adding a space filter: CHROOT=`grep "^chroot" $file|sed "s;.*= *;;" | tr -d " "` Regards.

John. Looks fine to me. Same configuration works in my Windows 7 64 bits. I have no access to Windows Server 2008 R2, but I would expect it to work the same. What are you securing with stunnel?... Perhaps the service you are securing is starting after stunnel? -----Original Message----- From: John Smith <java.dev.mtl(a)gmail.com> Date: Mon, 22 Sep 2014 11:09:21 To: Jose Diaz<josealf(a)rocketmail.com> Subject: Re: [stunnel-users] Stunnel as windows service doesn't start on restart.

stunnel beta (5.04b1) is available for testing
by Michal Trojnara 22 Sep '14

22 Sep '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Guys, Please feel free to try the beta version I just made available for download: https://www.stunnel.org/downloads/beta/stunnel-5.04b1.tar.gz https://www.stunnel.org/downloads/beta/stunnel-5.04b1-installer.exe The list of changes includes most of the issues recently discussed on the stunnel-users mailing list and more. * New features - Support for local mode ("exec" option) on Win32. - A more explicit service description provided for the Windows SCM (thx to Pierre Delaage). - TCP/IP dependency added for NT service in order to (hopefully) prevent initialization failure at boot time. - FIPS canister updated to version 2.0.8 in the Win32 binary build. * Bugfixes - load_icon_default() modified to return copies of default icons instead of the original resources to prevent the resources from being destroyed. - Reportedly more compatible values used for the dwDesiredAccess parameter of the CreateFile() function (thx to Pierre Delaage). - Partially merged UNICODE compilation fixes (thx to Pierre Delaage). - Partially merged Windows CE patches (thx to Pierre Delaage). - Fixed typos in stunnel.init.in and vc.mak. - Fixed incorrect memory allocation statistics update in str_realloc(). - Missing REMOTE_PORT environmental variable is provided to processes spawned with "exec" on Unix platforms. - Taskbar icon is no longer disabled for NT service. Some basic examples for local mode ("exec" option) on Windows: ; Service based on a command-line tool [netstat] accept = 8015 exec = c:\windows\system32\netstat.exe execargs = netstat -a ; Remote cmd.exe protected with SSL ; Certificate-based authentication needs to be configured here! [cmd] accept = 1337 exec = c:\windows\system32\cmd.exe Mike -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEARECAAYFAlQYYkoACgkQ/NU+nXTHMtGmfwCfSdHFmK8q5IRcS/CoFmYMZ40G zUEAoNUrIp0KAJ4+0LPwx+/1lJG6q2q/ =aSXM -----END PGP SIGNATURE-----
