torsocks works with wget but fails git-clone: "unable to lookup symbols in libc.so.6"

torsocks works with wget but fails git-clone: "unable to lookup symbols in libc.so.6"

[Mekeor Melire]

Problem
=======

This works fine:

    $ torsocks wget http://github.com/mekeor/config

This fails:

    $ torsocks git clone http://github.com/mekeor/config
    1491426097 ERROR torsocks[25849]: Unable to lookup symbols in libc.so.6((null)) (in init_libc_symbols() at torsocks.c:239)

Torifying browsers like netsurf-gtk, surf, w3m either also fail or don't
succeed. Using "torify" instead of "torsocks" results in the same.


Information
===========

My config.scm contains:

    (tor-service)

My whole config is available at:

    https://github.com/mekeor/config/blob/master/etc/guix/config.scm

The error is printed on this line in the code of torsocks:

    https://github.com/dgoulet/torsocks/blob/master/src/lib/torsocks.c#L239

I'm using version 20170405.20 of Guix (on GuixSD).


Question
========

Why does torsocks work with wget but doesn't work with git-clone? What
does the error mean? What does it have to do with libc? Is anybody able
to reproduce this?

That's not enough for torify (torification? to use torsocks / the SOCKS5
of tor) of applications. As I told you earlier, you need a SOCKSPort,
like so:

(services (cons*
            (tor-service
              (plain-file "torrc"
"SocksPort 127.0.0.1:9050\n"))))

This can be extended any other values you can find in "man torrc" as
long as you end the lines with "\n".
 
The (tor-service) is mostly just usable for offering onion services, and
we should document that the default is to leave it up to the person
using the system to
configure more behavior.

Why does the exact same command, namely “torify git clone
https://github.com/mekeor/config” work for other people on GuixSD then
without any custom tor-config but just (tor-service)? (Like, in
particular, I remember that rekado told me so.)

Also, after reconfiguring with the snippet you suggested, I still get
the same error.

Okay that is weird...

Okay, you need the SOCKSPort to make use of the SOCKS5 proxy. Apparently
torify is something else and I forgot about that. Sorry.

I assume your system and profile are recent enough?
I have never experienced this error, so I can't really help.
