Sorry guys, can i ask a stupid question? What reason to use stunnel on

Post by Research | FrenchFloridaThanks 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.
-----------------------------
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.
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 donât 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
mount -o rw,remount /system
mount -o ro,remount /system
So In summary, here is a step-by-step of what might work in getting the
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!

Hi cotex,
It is a statically linked ELF executable for Android/ARM.
It is only useful for people who customize their Android, and not for
end-users.

Best regards,

Post by Research | FrenchFloridaIn 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?
