[SOLVED] torsocks not working properly

Rosika · 06-12-2018, 08:06 AM

Hi hydrurga,

thank you so much for your help.

Alas the readme-file gives no hint as to un-installation.
Here´s the complete readme-file:

Quote:

[![Build Status](https://travis-ci.org/dgoulet/torsoc...oulet/torsocks)

What is torsocks?
-----------------

Torsocks allows you to use most applications in a safe way with Tor. It ensures
that DNS requests are handled safely and explicitly rejects any traffic other
than TCP from the application you're using.

Torsocks is an ELF shared library that is loaded before all others. The library
overrides every needed Internet communication libc function calls such as
connect(2) or gethostbyname(3).

This process is transparent to the user and if torsocks detects any
communication that can't go through the Tor network such as UDP traffic, for
instance, the connection is denied. If, for any reason, there is no way for
torsocks to provide the Tor anonymity guarantee to your application, torsocks
will force the application to quit and stop everything.

Requirements
-----------------

- autoconf
- automake
- libtool
- gcc

Installation
-----------------

$ ./configure
$ make
$ sudo make install

If you are compiling it from the git repository, run ./autogen.sh before the
configure script.

Using torsocks
--------------

Once you have installed torsocks, just launch it like so:

$ torsocks [application]

So, for example you can use ssh to a some.ssh.com by doing:

$ torsocks ssh username@some.ssh.com

You can use the torsocks library without the script provided:

$ LD_PRELOAD=/full/path/to/libtorsocks.so your_app

For more details, please see the torsocks.1, torsocks.8 and torsocks.conf.5 man
pages. Also, you can use -h, --help for all the possible options of the
torsocks script.

A configuration file named *torsocks.conf* is also provided for the user to
control some parameters.

I just rebooted my system.... just in case.
But that didn´t change anything.

Still: APT::Install-Recommends "true";

hydrurga · 06-12-2018, 08:23 AM

I just downloaded the source code from the place you got it and the file "INSTALL" in the root directory contains a great deal more information on the installation procedure.

It suggests that make uninstall might do the trick (run this from the source code directory you created to build the application).

Rosika · 06-12-2018, 08:39 AM

Hi and tnx.

It really didn´t occur to me to look elswhere than the readme-file.

Anyway, I un-installed torsocks with make uninstall running the command from the respective directory.
It seems to have worked as the command torsocks isn´t available any more.

Yet two entries remain:

/usr/local/lib/torsocks
/usr/local/share/doc/torsocks

But they are empty.

So: success.

hydrurga · 06-12-2018, 08:45 AM

Excellent. Right, I've figured out the Recommends issue. It turns out that 99synaptic contains an option to turn Install-Recommends on, and as 01norecommend comes before it alphanumerically, 99synaptic wins the day.

So the amended instructions are:

Code:

sudo su

cat > /etc/apt/apt.conf.d/99znorecommend << EOF
APT::Install-Recommends "0";
EOF

exit

Test it afterwards in the customary way.

Rosika · 06-12-2018, 08:52 AM

Tnx for figuring out that one.

But exactly what should I do about the

Code:

-rw-r--r-- 1 root root   29 Jun 12 14:40 01norecommend

that we´ve ceated? Should it be deleted before performing

Code:

sudo su

cat > /etc/apt/apt.conf.d/99znorecommend << EOF
APT::Install-Recommends "0";
EOF

exit

?

hydrurga · 06-12-2018, 08:56 AM

Housekeeping on the move - I like it. Although it will have no effect on the situation, given 99synaptic, you're right to clean up and delete it. You can do this with:

Code:

sudo rm /etc/apt/apt.conf.d/01norecommend

hydrurga · 06-12-2018, 09:10 AM

I'm off out for a while, so I recommend that you now install torsocks from the repo and see if it works any better than the manually installed one did.

Note that although you have now switched off Install-Recommends globally, if when installing a package and seeing the information that apt provides before it actually installs it, you decide that you want to auto install the recommended packages for that package, you can use the --install-recommends option in apt-get.

Rosika · 06-12-2018, 09:11 AM

Great success again.
I did everything as described and now:

Code:

rosika@rosika-Lenovo-H520e ~> apt-config dump | grep Recommends
APT::Install-Recommends "0";

Tnx so much!

And now apt-get -s install torsocks gives me

Code:

apt-get -s install torsocks

As soon as I can say more about it I´ll post.

In the meantime: a great thank-you for your help.

hydrurga · 06-12-2018, 09:12 AM

Yes, go ahead.

Rosika · 06-12-2018, 09:58 AM

@ all:

Hi again,

Installation went fine.

But alas: torsocks is not working as expected.
torsocks rhythmbox for example starts rhythmbox. But again: no internet-connection can be established.

Code:

(rhythmbox:13621): Rhythmbox-WARNING **: Unable to grab media player keys: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SettingsDaemon was not provided by any .service files
[Jun 12 16:48:05] PERROR torsocks[13621]: socks5 libc connect: Verbindungsaufbau abgelehnt (in socks5_connect() at socks5.c:185)

----- connection refused -----
The problem with firefox also remains the same (see post #1).

What does work is torsocks --shell ("Create a new shell with LD_PRELOAD including torsocks(8).")
But I can´t see any good use in that.

Seems nothing more can be done about it. It´s a real shame - after all the work that went into making it run.
Nevertheless:
Thank you so much for yor help and all the effort of yours, hydrurga!

Greetings
Rosika

@ Turbocapitalist:

Thanks a lot for your help, too.

*****UPDATE*****

After doing a bit of research I found some additional info as to the fault: https://www.tuicool.com/articles/EJJrmmy

The user got this info:

Code:

root@kali:~# torsocks curl icanhazip.com
[Dec 28 20:20:26] PERROR torsocks[2979]: socks5 libc connect: Connection refused (in socks5_connect() at socks5.c:185)
curl: (6) Could not resolve host: icanhazip.com
root@kali:~#

, which is precisely the same error-message I got.

It goes on like this:

Opps, that just means I forgot to start tor service. Start tor application using the following command:

Code:

root@kali:~# service tor start
root@kali:~#

Now try again:

Code:

root@kali:~# torsocks curl icanhazip.com
197.231.221.211
root@kali:~#

That´s it. That´s what I cannot do. There is no tor.service with me.
Seems that tor.service is automatically installed when installing tor itself.

But as torsocks doesn´t require tor to be installed (see apt show torsocks) I´m out of my wits......

hydrurga · 06-12-2018, 12:04 PM

Is the following any use? It refers to the Tor port.

hydrurga · 06-12-2018, 12:09 PM

So that I can understand, you say that you have tor-browser-bundle on a stick. Are you planning on putting torsocks on the stick as well, or is it for your main machine? If the latter, why don't you want to install Tor on your main machine? (it shouldn't affect the copy of tor on your stick).

P.S. Don't get out of your wits, or give up. This is a good learning experience (for us both, since I'm not used to using Tor on Linux).

Rosika · 06-13-2018, 04:34 AM

Hi again hydrurga,

your´re most kind. Thanks for your help.

As far as your link is concerned the user says:

Quote:

I want to Tor in terminal. This is what I used to do and it was working without any issue:

running Tor Browser
running torify or torsocks before the command in terminal

It seeems that he has Tor-Browser or Tor-Browser-Bundle (or whatever) locally installed on his system.
Otherwise torify wouldn´t work as this seems to be an integral part of Tor.
So there´s the difference.

In the meantime I´m convinced that Tor has to be locally installed in order to get torsocks to work. (see https://www.tuicool.com/articles/EJJrmmy)

tor.service
has to be available, I think.

Quote:

you say that you have tor-browser-bundle on a stick. Are you planning on putting torsocks on the stick as well, or is it for your main machine?

Well, I have made it my policy to install as few programms as possible on my local machine (the traditional way). So any "portable" programmes are welcome.
Plus ubutuusers.de states

Quote:

Das Tor-Browser-Bundle {en} (TBB) ist die Variante, die von den Tor-Entwicklern empfohlen wird (Gründe . Das Tor-Browser-Bundle ist ein in sich stimmiges, geschlossenes Programmpaket mit den Elementen

.

That basically means that Tor-Browser-Bundle (Webdownload) is recommended by the Tor-developers themselves.
For reasons see https://www.torproject.org/projects/torbrowser/design/.
So I thought why bother to install it locally?

In fact I don´t have tor-browser on a stick but on my system:
I start it like this:

Code:

firejail --private=/home/rosika/Schreibtisch/Dokumente/work/tor-browser_de ./start-tor-browser.desktop

(Yeah, I sandbox almost everything....

)
Therefore I didn´t intend to install Tor/Tor-browser locally.
The thing is don´t see a way to get torsocks to work alongside my "portable installation".
Reason: no tor.service running.

So that´s my current situation.

Greetings.
Rosika
