Re: [stunnel-users] How do I use the Stunnel download on android?
by Research | FrenchFlorida 09 Dec '15

09 Dec '15

Thanks for the reply. I'm not sure what " statically linked ELF executable for Android/ARM" means yet, but I will look it up. ;) Since I sent the message I did a lot of digging that yielded me very little details. In fact I only came a cross a few mentions that stunnel could be used on android but no examples of how that was implemented. After a vague hint I managed to deduced how the file worked, but it took me a little more independent research to understand how to make it, at least execute. I'm not new to linux but am new to android so not as familiar to how the system works in general. I did see that an android app was on your todo list. In the meanwhile however, may I suggest a little howto for Android that could get a user started in using the app. Stunnel is an amazing application and since I was able to figure it out I made myself a guide on how to set it up (Minus actually creating the configuration) so that I can at least know how to execute stunnel. Since I already did the research I offer you my very unorganized primer on how to set it up below. Perhaps it would be useful for some to have a better version of this doc on the site, and if not, well at least a well determined person can find this topic in the mailing list, because there will be only one other topic with the word "Android" in the title so it can perhaps get a user out of jam more quickly without. Here is my guide: ----------------------------- Chances are that "It is a statically linked ELF executable for Android/ARM." Means that within the stunnel-android.zip resides one file, and that file is the executable file for stunnel. It is in fact the defacto program that under linux you would see in /etc/local/bin/stunnel if that was where you installed it. This means that the requirements to use this file are as such: 1. Your phone probably needs to be rooted 2. You will need access to a terminal on your phone (Terminal Emulator) 3. There is no "APP" to run stunnel it is a command line file There are probably two reasons you would want to use stunnel on your phone. 1. You are an app developer that wants to use stunnel to connect one part of your app to something else, and therefore will incorporate this script within your app. I don't know how to make apps yet so that's probably as useful as I can make the description for you. 2. You are a user that has already used stunnel on your machine and wants to use it on your phone too. [The rest of the guide assumes this is the case.] Assuming the latter, what do you need to do to get it running? 1. Move the stunnel application to your phone. 2. As you would do in linux open the terminal 3. Run stunnel like a command If you get an error message saying it is not executable, or that permission is denied it is because of one of two things. Maybe you need to mark the file as executable Chmod +x ./stunnel Terminal Emulator's chmod does not understand "+x" so you will have to change the permission to Chmod 700 ./stunnel 700 means Read-Write-Execute for the user. If it doesn't work try 770 and 777 However you are likely to still receive that error on some phones. (I'm guessing, just because it happened to my phone I am not assuming it will happen to all phones.) Some phones forbid there to be an executable script within the /sdcard/ directory. Therefore you have to move it somewhere else. I don’t know where the proper place for such a file is, I moved mine to /system/bin/ therefore the script is callable by /system/bin/stunnel Another Caveat!! My phone's /system folder is not writable!! Therefore before you can even move the file you need to make the system folder writable: mount -o rw,remount /system Once moved needs to be made readonly again: mount -o ro,remount /system So In summary, here is a step-by-step of what might work in getting the script to an executable state on Android: 1. Root phone 2. install terminal emulator 3. get stunnel script onto your phone somehow 4. mount -o rw,remount /system 5. cp /sdcard/Download/stunnel /system/bin/stunnel 6. chown 700 /system/bin/stunnel 7. mount -o ro,remount /system 8. /system/bin/stunnel /path/to/conf/file* Now as if you are on linux you should probably** be able to run stunnel. *I haven't tested it out with conf files yet. ** I'm able to run stunnel --version so stunnel in and of itself is "working" ----------------------------- If this guide is any good to you guys, please feel free to use, I would love to contribute in some way. :) Thanks! -Cotex -----Original Message----- From: stunnel-users [mailto:stunnel-users-bounces@stunnel.org] On Behalf Of stunnel-users-request(a)stunnel.org Sent: Tuesday, December 08, 2015 7:00 PM To: stunnel-users(a)stunnel.org Subject: stunnel-users Digest, Vol 137, Issue 10 Send stunnel-users mailing list submissions to stunnel-users(a)stunnel.org To subscribe or unsubscribe via the World Wide Web, visit https://www.stunnel.org/cgi-bin/mailman/listinfo/stunnel-users or, via email, send a message with subject or body 'help' to stunnel-users-request(a)stunnel.org You can reach the person managing the list at stunnel-users-owner(a)stunnel.org When replying, please edit your Subject line so it is more specific than "Re: Contents of stunnel-users digest..."

SSL compression in 5.27
by Udo Erdelhoff 08 Dec '15

08 Dec '15

Hi, while testing the upgrade from stunnel 5.26 to stunnel 5.27 on Solaris, one of the tools I use reported that SSL compression was now supported/possible on connections to an stunnel 5.27 instance; this was not the case with 5.26 or earlier. Unfortunately, it is not possible to demonstrate this using openssl as client, I found this using TestSSLServer, which is java-based and available from http://www.bolet.org/TestSSLServer/. With 5.26: | $ java -jar TestSSLServer.jar $server 443 | Supported versions: TLSv1.2 | Deflate compression: no | Supported cipher suites (ORDER IS NOT SIGNIFICANT): | TLSv1.2 | TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 | TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 | ---------------------- | Server certificate(s): | 4c57045b3f8f9cdd6f487e59a5b008ccb9d38693: CN=***, OU=***, O=***, C=*** | ---------------------- | Minimal encryption strength: strong encryption (96-bit or more) | Achievable encryption strength: strong encryption (96-bit or more) | BEAST status: protected | CRIME status: protected Note: "Deflate compression: no", "CRIME status: protected" With 5.27: | $ java -jar /prod/certmon2/bin/TestSSLServer.jar $server 443 | Supported versions: TLSv1.2 | Deflate compression: YES | Supported cipher suites (ORDER IS NOT SIGNIFICANT): | TLSv1.2 | TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 | TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 | ---------------------- | Server certificate(s): | 4c57045b3f8f9cdd6f487e59a5b008ccb9d38693: CN=***, OU=***, O=***, C=*** | ---------------------- | Minimal encryption strength: strong encryption (96-bit or more) | Achievable encryption strength: strong encryption (96-bit or more) | BEAST status: protected | CRIME status: vulnerable With 5.27, I get "Deflate compression: YES" and "CRIME status: vulnerable". Server OS: Solaris 10/SPARC or Solaris 11/SPARC (others not tested) OpenSSL: 1.0.1p or 1.0.1q (others not tested) Client: TestSSLServer Both stunnel and OpenSSL are self-compiled using Solaris Studio 12.4. The stunnel.conf in question: sslVersion = TLSv1.2 ciphers = ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256 cert = test1.crt key = test1.key verify = 2 [test] client = no accept = A.B.C.D:443 connect = 127.0.0.1:8080 The scanner from SSL Labs should be able to check this as well, but I do not have the neccessary modern Python available. I will check if I can reproduce the problem on something a little more mainstream than Solaris 10/11 over the weekend. --

How do I use the Stunnel download on android?
by Research | FrenchFlorida 07 Dec '15

07 Dec '15

In the download section of the site, there is a zip for android. Inside this file is a single file, without any extention. How do I install this, I have found no documentation anywhere on the web. Can anybody guide me, or give me a hint. Is this something I do on the phone, or that I do from the computer first? -cotex

Failover behavior with stunnel
by Thireus 30 Nov '15

30 Nov '15

Hi, I have a couple of questions regarding failover with stunnel: 1. I would like to know if there is a way to use failover with two servers with two different set of TLS cert/key. The following rule doesn't work, because the cert and key parameters are overwritten, but it shows what I would like to achieve: [failover] accept = 127.0.0.1:4441 <http://127.0.0.1:4441/> cert = cert_1.cert key = key_1.pem connect = server-1:1234 cert = cert_2.cert key = key_2.pem connect = server-2:1234 2. On the same topic, I would like to know if there is an option that could open the local port (accept) only when the connection (connect) is established? The problem I'm facing is that I use a PAC profile with failover on several stunnel entries: "return PROXY 127.0.0.1:4441 <http://127.0.0.1:4441/>; PROXY 127.0.0.1:4442 <http://127.0.0.1:4442/>; PROXY 127.0.0.1:4443 <http://127.0.0.1:4443/>;". However, when one of the remote server is down (i.e. server-1), it is not easily detected by web-browsers (Chrome does not seem to detect it well), and so instead of switching to the next PROXY, it simply dies on the first one. If the port 4441 relative to server-1 (which is unavailable) was closed, then the webrowser could easily detect it and switch to the second server with port 4442. 3. Is there another way to tweak stunnel behavior when a remote server is down? I'm thinking about a couple of things, like being able to switch to a different rule set: [failover1] accept = 127.0.0.1:4441 <http://127.0.0.1:4441/> cert = cert_1.cert key = key_1.pem connect = server-1:1234 connect = 127.0.0.1:4442 <http://127.0.0.1:4442/> ; This is failover2 [failover2] accept = 127.0.0.1:4442 <http://127.0.0.1:4442/> cert = cert_2.cert key = key_2.pem connect = server-2:1234 Or maybe there are some options that I'm not aware of to timeout connections more efficiently: so that Chrome (or other clients using HTTP proxies) will immediately know that stunnel cannot connect to the remote server and so that the proxy is down. Thank you for your help. Cheers, Thireus.
