Requests to cloud server that requires host header
by Lorne Kates 13 Nov '24

13 Nov '24

(related to Akamai message from before-- but I have better troubleshooting information). I'm tying to route traffic through stunnel to a "cloud" based-endpoint. That endpoint has a static server name-- test.authorize.net. (This is the dev sandbox for auth.net). But if you do an nslookup on test.authorize.net, you'll get back a different servername and IP, because it's so wonderfully "cloud". Stunnel apparently tries to connect to the nslookup value. The server rejects the request because it can't route it back to test.authorize.net. I've tried adding "delay = yes" and "sni = test.authorize.net", but neither work. To see this in action, a simple setup with any accept, then connect to test.authorize.net:443 in client = yes mode. This is what a valid response looks like (13 -- give me the darn merchant ID in a POST): https://test.authorize.net/gateway/transact.dll This is what you'll get if you try to use stunnel (400 invalid url) : https://23.195.204.150/gateway/transact.dll So how can I get stunnel to send the proper Request Header (host: test.authorize.net), make sure it's using http/1.1, etc?

Stunnel & Gmail security
by BOXI31 TEST 16 Oct '20

16 Oct '20

Hi all, To make "Stunnel 5.31" work with Gmail, I have to go in security settings of Gmail and "allow less secure apps to access my account". Is it mandatory ? Is it possible to set Stunnel to access Gmail without lowering it security level ? How ? I checked in log file TLS v1.2 is used by Stunnel but Gmail still consider it as a "less secure app." ! Regards, Steve

Re: [stunnel-users] Is there a way to specify certificate content in stunnel config
by Eric S Eberhard 24 Jul '18

24 Jul '18

Use stunnel in inetd mode. Execute a script (or better C program). Copy the certificates for making the stunnel connection to a directory that is OK … then delete them immediately after stunnel starts. Hack – but might be OK for what you are doing. I am not sure why anyone would think it more secure to put the keys into the stunnel command than to just use them from a file … but I likely do not know enough about your application to make a judgement.

Is there a way to specify the actual certificate content in stunnel configuration (similar to other parameters like port numbers etc.,) so that the same can be leveraged.

Grok log parsing
by Manuele Trimarchi 24 Jul '18

24 Jul '18

I would ask if someone use Grok log parsing for stunnel and, if yes, what kind of filter statement are you using? At the moment I've just created 2 parser: STUNNEL_AcceptedConnectionParser %{date("yyyy.MM.dd HH:mm:ss"):date} LOG%{integer:loglevel}\[%{integer:session_id}\]\: Service \[%{word:csb_name}\-%{word:csb_port}\] accepted connection from %{ipv4:caller_ip}\:%{port:caller_port} and STUNNEL_ConnectionClosedParser %{date("yyyy.MM.dd HH:mm:ss"):date} LOG%{integer:loglevel}\[%{integer:session_id}\]\: Connection closed\: %{integer:byte_tx} byte$s$ sent to SSL\, %{integer:byte_rx} byte$s$ sent to socket I'm new with Grok and all the things related to log match-and-parse, so I think that there will be a much better solution than mine, anyway Google this time doesn't help unfortunately. Thank you so much to all those who will help me with this stuff! Manuele

Cross Compiling Stunnel-5.48 Using BoringSSL
by Jaymin D 24 Jul '18

24 Jul '18

Hi All, I want to cross compile the Stunnel-5.48 for my Android AOSP (arch64) platform using BoringSSL's 'libssl.so' and 'libcrypto.so' libraries. I have successfully cross compiled the BoringSSL in my AOSP and both .so file was generated for arch64 platform. Am using BoringSSL which was delivered with Android AOSP (Android 7). Am cross compiling using "build-android.sh" script. But, while cross compiling the Stunnel-5.48 facing error as below: ------------------------------------------------------------------------------------------------ VERSION=5.48 > DST=stunnel-$VERSION-android > # to build OpenSSL: > # ./Configure threads no-shared no-dso > --cross-compile-prefix=arm-linux-androideabi- > --prefix=/opt/androideabi/sysroot linux-armv4 > # make install > LDFLAGS="$LDFLAGS -L/home/jaymin/Desktop/boringssl_lib -fPIE" > export LDFLAGS > test -f Makefile && make distclean > mkdir -p bin/android > cd bin/android > ../../configure --with-pic --enable-shared --with-sysroot > --host=aarch64-linux-android --with-ssl=/home/jaymin/Desktop/boringssl_lib > configure: **************************************** initialization > checking for a BSD-compatible install... /usr/bin/install -c > checking whether build environment is sane... yes > checking for aarch64-linux-android-strip... no > checking for strip... strip > checking for a thread-safe mkdir -p... /bin/mkdir -p > checking for gawk... gawk > checking whether make sets $(MAKE)... yes > checking whether make supports nested variables... yes > checking build system type... x86_64-pc-linux-gnu > checking host system type... aarch64-unknown-linux-android > checking for aarch64-linux-android-gcc... no > checking for gcc... gcc > checking whether the C compiler works... yes > checking for C compiler default output file name... a.out > checking for suffix of executables... > checking whether we are cross compiling... no > checking for suffix of object files... o > checking whether we are using the GNU C compiler... yes > checking whether gcc accepts -g... yes > checking for gcc option to accept ISO C89... none needed > checking whether gcc understands -c and -o together... yes > checking for style of include used by make...

"Reverse" tunneling with stunnel.
by C. Petro 20 Jul '18

20 Jul '18

I have a client who is setting up a logging infrastructure involving a couple of DMZs forwarding logs into central logging points. They have to pass compliance audits (SOX, PCI at least) and have some rather specific desires in regards to how they want the log traffic to move, and which servers *initiate* the connections. Which is to say they want the internal servers to set up tunnels to the DMZ servers and then the forwarders use that tunnel to deliver logs back. Lemme see if I can ascii art this: central1----------------------------------dmz1 \____________________ / _____________________\ _/ / \ central2----------------------------------dmz2 Something like that. Central1=10.10.1.2 Central2=10.9.1.2 DMZ1=172.18.0.5 DMZ2=172.20.0.5 Firewalls are in effect. I have gotten it set up so that I can initiate a connection FROM Central1 to DMZ2. [Tunnel_to_DMZ2] client = yes accept = 3002 connect = 172.20.0.5:5000 And [Tunnel_from_Central1] accept = 5000 connect = 3000 Like I said, I can open a tunnel from Central1 to DMZ2, but can't get traffic to pass backwards--I get a message in the log saying the session is closed. Is it possible to set stunnel up in a "reverse tunnel" mode--one where the connect is initiated from one end, but the other does most of the message passing? What I am missing? Thanks, Petro.

TLS alert (read): fatal: bad record mac (windows)
by Per Gunnarsson 19 Jul '18

19 Jul '18

I found it after looking once more in the log file. PSK client configured for identity "ï»¿user2" (the identity in the secrets.txt is user2:secretkey, somehow those three weird characters are added on windows) I got around it by copying the secrets.txt file to the server so that the secrets.txt on the server also begins with "ï»¿user2" but I suspect it's a bug.

Is there a way to specify certificate content in stunnel config
by Hari 19 Jul '18

19 Jul '18

Hi, I have a requirement where in i cannot specify the certificate and/or private key details as "files" to stunnel configuration, owing to the location and/or file system availability for stunnel to access them. Is there a way to specify the actual certificate content in stunnel configuration (similar to other parameters like port numbers etc.,) so that the same can be leveraged. ThanksHari | | Virus-free. www.avg.com |

TLS alert (read): fatal: bad record mac (windows)

Hello! I am trying to set up stunnel from a windows box to a VPS. I have working tunnels from a FreeBSD box to the VPS. On the VPS, the config looks like: [socks_server] protocol = socks PSKsecrets = /my/secret/location/secrets.txt accept = xxx.xxx.xxx.xxx:xxxx [ssh] PSKsecrets = /my/secret/location/hecrets.txt accept = xxx.xxx.xxx.xxx:xxxx connect = 127.0.0.1:22 On the windows box, the config looks like this: [socks_client2] debug = 7 client = yes PSKsecrets = c:\my\secret\location\secrets.txt accept = 127.0.0.1:1080 connect = xxx.xxx.xxx.xxx:xxxx The log on Windows looks like this: 2018.07.19 13:13:09 LOG5[main]: stunnel 5.48 on x86-pc-msvc-1500 platform 2018.07.19 13:13:09 LOG5[main]:
