Hi Jose, That did it, thanks. Stupid thing is I check that I had OpenSSL but not the devel package. Mark one up for my stupidity (again). ~Yours, Scott On 30 March 2012 16:11, <josealf(a)rocketmail.com> wrote: > Scott, > > Most likely you don't have openssl-devel package installed. > > Regards > Jose > > -----Original Message----- > From: Scott McKeown <scott(a)loadbalancer.org> > Sender: stunnel-users-bounces(a)stunnel.org > Date: Fri, 30 Mar 2012 16:00:45 > To: <stunnel-users(a)stunnel.org> > Subject: [stunnel-users] stunnel 4.53 make error > > _______________________________________________ > stunnel-users mailing list > stunnel-users(a)stunnel.org > http://stunnel.mirt.net/mailman/listinfo/stunnel-users > > > >

stunnel 4.53 make error

Hi Guys, Just tried to install stunnel-4.53 onto a virgin Cento6.2 x64 system with HAProxy (box is fully patched too), However, every time I runt the 'make' command I get the following output. I've had a bit of a hunt around but this is a little outside of both my comfort zone and my knowledge levels so any help would be great.

SNI with protocol=proxy ?
by Marek Majkowski 29 Mar '12

29 Mar '12

Hi, I'm having trouble using SNI with protocol=proxy. Stunnel seems to ignore protocol option defined in the 'children', for example now protocol will be ignored: [https_default] accept = 443 connect = 10443 cert = a.crt key = a.key [https_one] sni = https_default:one.org protocol = proxy connect = 10444 cert = one.crt key = one.key On the other hand when defined on the 'default' resource, the connect option seems to be ignored: [https_default] accept = 443 protocol = proxy connect = 10443 cert = a.crt key = a.key [https_one] sni = https_default:one.org connect = 10444 ;; nope! still 10443 cert = one.crt key = one.key Any suggestions? Cheers, Marek

RMI with SSL
by Anoop Joseph 29 Mar '12

29 Mar '12

Hi, We have an existing RMI server which is not SSL aware and is based on Java version 1.4.1. We want to use stunnel to make this existing RMI server SSL aware. Checking the official website of stunnel the support to following protocols were found cifs , connect, imap, nntp, pgsql, pop3, proxy and smtp. As no reference to JRMP was available, wondering if stunnel can be used to make the existing non SSL RMI server SSL aware. If this is possible then we belive that it would be achived by providing the mapping between the port configured with stunel and the existing port used by RMI. Also the eixsitng RMI server would have to undergo minial change using this approach. Your help is highly appreciated. Thanks in advance. Best Regards, Anoop

Can this be done by Stunnel
by Alan C. Bonnici 23 Mar '12

Thomas, After a few exchanges a few hours ago with the folk at STunnel I can confirm that the "problem" was that the company uses host headers. Here is the procedure I used to sort it out: 1. Modify the windows host file and add the following entry 127.0.0.1 rest.nexmo.com. If your STunnel ir running on a different machines, set the 127.0.0.1 to the IP address of the Stunnel server. 2. Add the following to the stunnel.conf file (you may alter the port) [nexmo] client = yes accept = 9013 connect = 174.120.166.82:443 TIMEOUTclose = 0 3. Start sending secure SMSs as follows (note the port number much match the one set in stunnel.conf) http://rest.nexmo.com:9013/sms/xml?username=xxxxxxx&password=xxxxxxx&from=xx xxxxxx&to=xxxxxxx&text=xxxxxxx This will bypass the issue related to host headers and I can confirm that the solution has worked. The setup is useful if using server technology that does not natively support SSL as is our case. Hope this helps. Alan ---------------------------------------------------------------------------- ---------------------------------------- Alan; While I don't generally use Stunnel for HTTPS, I found your question interesting. Since I'm always trying to experiment with configurations of and applications for Stunnel, I decided to give it a whirl. I'm happy to confirm that it works just fine for me. I'm not connecting to the site in your example, but the principle is the same. Perhaps the answer lies in how your browser parses that URL, and how, as a result, it inserts that data into the stream. For the experiment, I used Firefox 9.0.1 running under Windows XP x86 with Stunnel version 4.53. My test config was: debug = 6 fips = no delay = yes output = stunnel.log [https] client = yes accept = 127.0.1.21:7777 connect = www.host.domain:443 Where www.host.domain is just an example. As you can see, I did not include any TIMEOUTclose statement in my config file. Then I pointed the browser at http://127.0.1.21:7777/do/mypage/longparameterstringhere. As far as I can tell, all of the parameters contained in that string were passed on to the web site without any difficulty. You might want to check your log window to see what's happening when you try to connect via Stunnel.

Hi, I am new to STunnel. I am trying to connect to a service provided by nexmo.com. If from a browser I type the following: https://rest.nexmo.com/sms/xml?username=xxxxxxx <https://rest.nexmo.com/sms/xml?username=xxxxxxx&password=xxxxx&from=xxxxxxx &to=xxxxxxx&text=xxxxxxxxxx> &password=xxxxx&from=xxxxxxx&to=xxxxxxx&text=xxxxxxxxxx The process works. I just installed stunnel and have the following config file ; Debugging stuff (may useful for troubleshooting) ;debug = 7 ;output = stunnel.log ; Certificate/key is needed in server mode and optional in client mode cert = stunnel.pem ;key = stunnel.pem ; Disable support for insecure SSLv2 protocol options = NO_SSLv2 [nexmo] client = yes accept = 9012 connect = rest.nexmo.com:443 TIMEOUTclose = 0 When I type http://127.0.0.1:9012/sms/xml? username=xxxxxxx&password=xxxxx&from=xxxxxxx&to=xxxxxxx&text=xxxxxxxxxx it does not. Can anyone please confirm whether what I am trying to do is doable and maybe highlight what I am doing wrong. Regards, Alan

Intermittent connection resets
by Jordan K 22 Mar '12

22 Mar '12

Hi, I've spent the better part of the day trying to find answers on this, and haven't had much luck. I have two systems that talk to eachother via stunnel. In the last week or so, I have noticed a number of errors in the application using the tunnel (messaging application), requiring multiple re-sends, etc. This is my setup. Both server and client run CentOS 6.2, with the RPM version of stunnel. Though it isn't the latest version, I believe RedHat do release any critical bugs in their updated RPMs. I did also go through the ChangeLog but couldn't find anything implemented since 4.29 that seemed to deal with what I'm seeing. stunnel 4.29 on x86_64-unknown-linux-gnu with OpenSSL 1.0.0-fips 29 Mar 2010 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /etc/stunnel/stunnel.pem ciphers = ALL:!aNULL:!eNULL:!SSLv2 key = /etc/stunnel/stunnel.pem session = 300 seconds stack = 65536 bytes sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none Socket option defaults: Option Accept Local Remote OS default SO_DEBUG -- -- -- 0 SO_DONTROUTE -- -- -- 0 SO_KEEPALIVE -- -- -- 0 SO_LINGER -- -- -- 0:0 SO_OOBINLINE -- -- -- 0 SO_RCVBUF -- -- -- 87380 SO_SNDBUF -- -- -- 16384 SO_RCVLOWAT -- -- -- 1 SO_SNDLOWAT -- -- -- 1 SO_RCVTIMEO -- -- -- 0:0 SO_SNDTIMEO -- -- -- 0:0 SO_REUSEADDR 1 -- -- 0 SO_BINDTODEVICE -- -- -- -- TCP_KEEPCNT -- -- -- 9 TCP_KEEPIDLE -- -- -- 7200 TCP_KEEPINTVL -- -- -- 75 IP_TOS -- -- -- 0 IP_TTL -- -- -- 64 TCP_NODELAY -- -- -- 0 Common config (basically default file released by RedHat, with certs and ports configured) : ---------------- ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = SSLv3 ; Some security enhancements for UNIX systems - comment them out on Win32 chroot = /var/run/stunnel/ setuid = stunnel setgid = stunnel ; PID is created inside the chroot jail pid = /stunnel.pid ; Some debugging stuff useful for troubleshooting debug = 7 output = /var/log/stunnel.log ------------------- When the connection breaks, the logs (debug=7) on both sides are: Client: 2012.03.21 19:58:14 LOG7[30685:140185543952128]: SSL state (connect): before/connect initialization 2012.03.21 19:58:14 LOG7[30685:140185543952128]: SSL state (connect): SSLv3 write client hello A 2012.03.21 19:58:14 LOG3[30685:140185543952128]: SSL_connect: Peer suddenly disconnected 2012.03.21 19:58:14 LOG5[30685:140185543952128]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket Server: 2012.03.21 19:58:14 LOG3[22230:140462283343616]: SSL_accept: Peer suddenly disconnected 2012.03.21 19:58:14 LOG5[22230:140462283343616]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket As I mentioned, it happens intermittently, with probably 50% of the connections working just fine, and the rest being disconnected. It ALWAYS seems to happen just after the client 'write client hello A', as opposed to later in the SSL handshake. I ran a tcpdump on both sides, it is below. Note that both the client and the server are NATd behind firewalls, on the server the port stunnel listens on (31112) is opened through the firewall.

Neither side originates any RST packets. When the connection is successful, the tcpdump looks a lot more normal, with an appropriate FIN exchange closing the session once the data has been sent. My questions are - am I missing something obvious? Am I correct in reading the above as some firewall or router between the two servers breaking the TCP connection by sending TCP RSTs to both endpoints? any help is appreciated. jordan

running stunnel from inetd

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

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

Hi guys, Right now I am working on this issue trying to encrypt the communication between terminals and our back of house computer. I am trying to solve this problem with stunnel. If the terminal is 'smart' like computer, it will be no issue. implement the stunnel on both end. But it come to be a problem there is some dumb terminal, No way to set up stunnel in its side. I not sure stunnel can works here any more. if not, is there any other methods that may work? -- *Dewen Kong*

Stunnel->Stunnel Failure Behavior...
by Matt Wise 13 Mar '12

13 Mar '12

I'm using Stunnel in our environment to tunnel our ZooKeeper connections... it works reasonably well as long as ZooKeeper is running on our ZooKeeper servers properly. Here's an example of our server and client configs: Server: > cert = /etc/stunnel/zookeeper.pem > key = /etc/stunnel/zookeeper.key > CAfile = /etc/stunnel/zookeeper_ca.pem > verify = 2 > sslVersion = TLSv1 > setuid = stunnel4 > setgid = stunnel4 > pid = /var/lib/stunnel4/zookeeper.stunnel4.pid > socket = l:TCP_NODELAY=1 > socket = r:TCP_NODELAY=1 > TIMEOUTconnect = 2 > debug = 4 > [zookeeper] > accept = 0.0.0.0:2182 > failover = rr > connect = 127.0.0.1:2181 Client: > cert = /etc/stunnel/zookeeper.pem > key = /etc/stunnel/zookeeper.key > CAfile = /etc/stunnel/zookeeper_ca.pem > verify = 2 > sslVersion = TLSv1 > client = yes > setuid = stunnel4 > setgid = stunnel4 > pid = /var/lib/stunnel4/zookeeper.stunnel4.pid > socket = l:TCP_NODELAY=1 > socket = r:TCP_NODELAY=1 > TIMEOUTconnect = 2 > debug = 4 > [zookeeper] > accept = 127.0.0.1:2182 > failover = rr > connect = zookeeper1:2182 > connect = zookeeper2:2182 > connect = zookeeper3:2182 Now the intended behavior is that if 'zookeeper1', 'zookeeper'2, or 'zookeeper3' go down that the client will re-establish a connection with one of the other servers. However, that doesnt seem to be happening. Instead, when the connection dies, Stunnel seems to go into a massive loop trying to re-connect to the original server. > Feb 22 21:41:24 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) > Feb 22 21:41:25 staging-i-123.xxx stunnel: LOG3[10717:3073788784]: connect_blocking: getsockopt 123.123.123.123:2182: Connection refused (111) Whats missing in my config to make the failover work properly? —Matt

How to get stunnel to listen on an IPv6 interface?
by jshardlo 11 Mar '12

11 Mar '12

Hi - my server was recently connected to IPv6 as well as the original IPv4 network. I have been using stunnel for some time on the IPv4 network but now that I have IPv6 access I can't work out how to get stunnel to listen on that interface as well. I checked that my stunnel has IPv6 support:- /usr/sbin/stunnel -version stunnel 4.15 on i686-redhat-linux-gnu with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /etc/stunnel/stunnel.pem ciphers = AES:ALL:!aNULL:!eNULL:+RC4:@STRENGTH key = /etc/stunnel/stunnel.pem session = 300 seconds TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none I have a configuration like this: [pop3s] accept = 995 connect = 110 But when I do netstat I can see that it is only listening for port 995 on IPv4... netstat -an | grep 995 tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN netstat -an -A inet6 | grep 995 And of course when I connect to port 995 over the IPv6 network I get "connection refused". Any ideas how to get stunnel to listen on the v6 address? Thanks ! -- View this message in context: http://old.nabble.com/How-to-get-stunnel-to-listen-on-an-IPv6-interface--tp… Sent from the Stunnel - Users mailing list archive at Nabble.com.

Stunnel.conf won't load with certain ciphers.
by Thomas Eifert 09 Mar '12

09 Mar '12

Hello all: I'm running Stunnel 4.52 under WinXP SP3. Last night I had some questions about how the cipher list in Stunnel interacts with the cipher negotiation routine between client and server, so I did some experiments in an attempt to address those questions. In the course of doing so, I noticed that, if I attempt to load certain ciphers, Stunnel would stall at configuration load. Using OpenSSL to list TLS ciphers with 4.52's libraries yields the following: ~~~~~~~~~~~~~~~~~~~~~ C:\Program Files\stunnel>openssl ciphers -v -tls1 DHE-RSA-AES256-SHA SSLv3 Kx=DH Au=RSA Enc=AES(256) Mac=SHA1 DHE-DSS-AES256-SHA SSLv3 Kx=DH Au=DSS Enc=AES(256) Mac=SHA1 AES256-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 EDH-RSA-DES-CBC3-SHA SSLv3 Kx=DH Au=RSA Enc=3DES(168) Mac=SHA1 EDH-DSS-DES-CBC3-SHA SSLv3 Kx=DH Au=DSS Enc=3DES(168) Mac=SHA1 DES-CBC3-SHA SSLv3 Kx=RSA Au=RSA Enc=3DES(168) Mac=SHA1 DHE-RSA-AES128-SHA SSLv3 Kx=DH Au=RSA Enc=AES(128) Mac=SHA1 DHE-DSS-AES128-SHA SSLv3 Kx=DH Au=DSS Enc=AES(128) Mac=SHA1 AES128-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(128) Mac=SHA1 IDEA-CBC-SHA SSLv3 Kx=RSA Au=RSA Enc=IDEA(128) Mac=SHA1 RC4-SHA SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=SHA1 RC4-MD5 SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=MD5 EDH-RSA-DES-CBC-SHA SSLv3 Kx=DH Au=RSA Enc=DES(56) Mac=SHA1 EDH-DSS-DES-CBC-SHA SSLv3 Kx=DH Au=DSS Enc=DES(56) Mac=SHA1 DES-CBC-SHA SSLv3 Kx=RSA Au=RSA Enc=DES(56) Mac=SHA1 EXP-EDH-RSA-DES-CBC-SHA SSLv3 Kx=DH(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-EDH-DSS-DES-CBC-SHA SSLv3 Kx=DH(512) Au=DSS Enc=DES(40) Mac=SHA1 export EXP-DES-CBC-SHA SSLv3 Kx=RSA(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-RC2-CBC-MD5 SSLv3 Kx=RSA(512) Au=RSA Enc=RC2(40) Mac=MD5 export EXP-RC4-MD5 SSLv3 Kx=RSA(512) Au=RSA Enc=RC4(40) Mac=MD5 export C:\Program Files\stunnel> ~~~~~~~~~~~~~~~~~~~~~ As such, ciphers RC4-SHA and RC4-MD5 appear to be valid.

How to pass remote IP to local SMTP/POP3 server
by Zdenek Valach (INBOX) 08 Mar '12

08 Mar '12

Hi I have question, because I was not able to find answer anywhere on internet. I started to use Stunnel in server mode to provide POP3S/SMTPS functionality. Everything works fine except that I am missing remote IP of connecting client. I am using Windows version so I can not use transparent proxy mode working on Unix. Is there way how to make Stunnel for example after each establishment of TCP connection to send to SMTP/POP3 server port some special command like REMOTEIP 123.123.123.123<crlf> to pass this information there. I know it is not in SMTP/POP3 standard but it is simple for me extend behavior of SMTP/POP3 service by this command?

mknod: not owner building stunnel on Solaris SPARC 10 zone
by Jiri ROHLICEK 07 Mar '12

07 Mar '12

Hello,I've been building stunnel 4.52 on Solaris 10 SPARC zone. Configure and make went fine, make install failed in tools with error if uname | grep SunOS; then \ ../auto/install-sh -c -d -m 755 /tmp/stunnel/var/lib/stunnel/dev; \ mknod /tmp/stunnel/var/lib/stunnel/dev/zero c 13 12; \ chmod 666 /tmp/stunnel/var/lib/stunnel/dev/zero; \ fi SunOS mknod: Not owner -- mknod is not allowed in solaris zone, only in global. One of many notices of this error skayser's http://www.mail-archive.com/[email protected]/msg03031.html asks if mknod is needed on solaris 10. So I tried after configure comment out the mknod section in tools/Makefile. -- install-data-local: ... ... if uname | grep SunOS; then \ ${INSTALL} -d -m 755 $(DESTDIR)$(localstatedir)/lib/stunnel/dev; \ mknod $(DESTDIR)$(localstatedir)/lib/stunnel/dev/zero c 13 12; \ chmod 666 $(DESTDIR)$(localstatedir)/lib/stunnel/dev/zero; \ fi -- Now make install ends OK and stunnel works fine (I use it as client only). Isn't creating ./dev/zero not needed anymore? Thanks Jiri Rohlicek jrohlicek(a)aplis.cz

Couple of issues with 4.45
by Philippe A. 07 Mar '12

07 Mar '12

Hello, I have encountered a couple of issues with stunnel 4.45 on RHEL 5.5. I tried configuring stunnel to log messages in /var/log/messages and later found that messages were logged both in that file AND /var/log/messages. In stunnel.conf, I had specified: debug=local6.info In syslog.conf: local6.* /var/log/stunnel.log I could achieve what I wanted only with the combination of the following two options: syslog=no output=/usr/local/app/stunnel/var/stunnel.log Is this expected? The second issue I have noticed is that stunnel seems to have a bit of trouble handling the hup signal. If you start stunnel specifying a relative path to the config, sending hup will cause stunnel to log and error but it won't exit. 2012.03.01 16:31:29 LOG5[19000:0]: Reading configuration from file etc/server.conf 2012.03.01 16:31:29 LOG3[19000:0]: etc/server.conf: No such file or directory (2) 2012.03.01 16:31:29 LOG3[19000:0]: Cannot read configuration 2012.03.01 16:31:29 LOG3[19000:0]: Failed to reload the configuration file If you specify an absolute path, no error will be reported but stunnel will exit anyway.

No sub folders, calendar or contacts

05 Mar '12

Dear sirs I am using Ubuntu 11.10 64-bit, Outlook 2007 and 4 x gmail accounts (1 x personal (gmail.com) and 3 x business (baroni-limited.com, hosted by gmail). I have set up Stunnel, I belive the latest version and created a SSL license as instructed. The Stunnel Telnets OK and I can send and recieve eMails (I do send directly via my ISP rather than use Stunnel) without any problem. Where I seem to be having problems is that: I have no sub folders to each account. None are appearing. I have no calendars - I have followed the instructions but they fail to load. I have no contacts. Message from Outlook: Sync error > > Task 'Synchronizing subscribed folders for Baroni.' reported error > (0x800CCC0E) : 'Outlook cannot synchronize subscribed folders for Baroni. > Error: Cannot connect to the server.

An object cannot be found.' > Config attached - I hope. It is most likely I have missed something or done something wrong. I have not found anything to help me on the web or archives, could you please advise. If you feel you need a copy of the the logs, please advise and I shall happily provide what I can. I am assuming I have just missed something. -- Regards Jonathan

Stunnel in Client / Server configuration
by Michael Curran 04 Mar '12

Hello, I have 2 servers in different locations across the country. I am using them as a paired tunnel that both act as server and client Server A has this configuration (cert definitions left out on purpose, but exist and are valid) ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = all ; Some security enhancements for UNIX systems - comment them out on Win32 chroot = /var/lib/stunnel4 setuid = stunnel4 setgid = stunnel4 ; PID is created inside chroot jail pid = /stunnel.pid ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ;compression = rle TIMEOUTclose=0 ; 128-bit or highter only ciphers = HIGH:MEDIUM ; Workaround for Eudora bug options = DONT_INSERT_EMPTY_FRAGMENTS options = NO_SSLv2 ; Some debugging stuff useful for troubleshooting debug = local7.info ;warning [Tunnel from Server B] accept = 1.2.3.4:443 connect = 127.0.0.1:8082 [Tunnel to Server B] accept = 5.6.7.8:3132 connect = 9.10.11.12:4000 client = yes Server B (cert definitions left out on purpose, but exist and are valid) ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = all ; Some security enhancements for UNIX systems - comment them out on Win32 chroot = /var/lib/stunnel4 setuid = stunnel4 setgid = stunnel4 ; PID is created inside chroot jail pid = /stunnel.pid ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ;compression = rle TIMEOUTclose=0 ; 128-bit or highter only ciphers = HIGH:MEDIUM ; Workaround for Eudora bug options = DONT_INSERT_EMPTY_FRAGMENTS options = NO_SSLv2 ; Some debugging stuff useful for troubleshooting debug = local7.debug ;warning [Tunnel to Server A] accept = 10.1.2.3:9443 connect = 1.2.3.4:443 client = yes [Tunnel from Server A] accept = 9.10.11.12:4000 connect = 10.4.5.6:3132 Communication through Server A (client) to Server B (server) works as expected Communication through Server B (client) back to Server A (server) recieves this error curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol (this is all the further it gets, the client says hello and the server responds with this) If I skip the local stunnel config and pass the traffic publicly through to Server A (running in client mode), from Server B, I get the expected http response I setup to test the tunnel. Im just assuming that if I am passing from Stunnel from one system to stunnel on another, one of them should be client and the other should be server. This works well on our old configurations and as far as I can see from a stunnel and network route perspective all rules are identical. Why would it work from Server B to Server A on the response if I go directly to Server A, but fail locally? The configuration looks correct, what else could I check?

Multiple Config Files
by Scott McKeown 02 Mar '12

02 Mar '12

Hi All, I'm new to the STunnel system but I'm loving what I have seen so far. However, I was wondering if its possible to have a setup something along the lines of the following: general.cfg - containing my general server system details http.cfg - containing the details of my HTTP server pop3.cfg - containing the details of my pop3 server etc. etc. but linking them all from one file so that if I want to remove the pop3 service I can just remove the pop3.cfg file and one line from the base file. I hope that someone understands what I'm getting at but if you need any more info please just let me know. Yours, Scott

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

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) 24 Feb '12

24 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...

Stunnel for Android
by Huzella Balázs 23 Feb '12

23 Feb '12

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 15 Feb '12

15 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?

Improving SSL security and protecting against the BEAST attack
by Shannon Carver 06 Feb '12

06 Feb '12

Hi all, Long time lurker, but first time poster on the Stunnel mailing list. I'm currently entering into a business partnership with a prominent media group, and as such they've got some strict guidelines by which their partners should abide by when it comes to Security/Encryption, both for brand protection, and making sure that both sides are sufficiently covered (at least from a general scan point of view). Basically the big thing that is coming up in my testing now (predominantly using the Qualysis tool at www.ssllabs.com) is that I'm vulnerable to the BEAST attack, CBC-Mode vulnerabilities and a potential issue of DoS attack due to server accepting Client Side Re-negotiation. I've spent days now trawling the web looking for a solution, but haven't really found anything of use yet, short of disabling CBC Ciphers completely (e.g 'cipher = RC4-SHA:RC4-MD5:!SSLv2:!ADH:!EDH:!EXP:!aNULL:!eNULL:!NULL' or similar), but I fear this me be too restrictive when it comes to client support. I guess my question is, are there other stunnel users who've been in the same situation, and is there a recommended cipher/options list when using Stunnel for HTTPS? Thanks in advance Shannon
