Long Wiki Edits Thread

This nails it perfectly! Please add to the wiki. Where? Good question, next question… :slight_smile:

Certainly it needs to be referenced from https://www.whonix.org/wiki/Free_Support_Principle so that chapter is better justified.

This chapter could definitely use some beautification. No rush :wink:

BTW if fixed a few mistakes. There are always a few stragglers.

Done!

Added to Wiki/FAQ . I will add link from Free Support Principal after the chapter is pushed to the wiki. Also, I made a new name up for the chapter. Any better suggestions?

Our Qubes Dispvm instructions where pushed to the Qubes docs

Great work!! :slightly_smiling_face:

https://github.com/QubesOS/qubes-doc/pull/643

The instruction numbering was somehow messed. All steps are numbered “1.” instead of 1,2,3…

I will ask what need to be done. Maybe make another pull request to fix.

Debugging with curl

Trying to use curl rather than curl.anondist-org is a common mistake when debugging Whonix network issues.

curl is a symlink -> curl.anondist which is a symlink -> uwt which runs curl under torsocks which then makes it use Tor running on localhost for stream isolation.

To use curl

  • command must be run under user clearnet
  • uwt steam isolation wrapper must be deactivated

In Whonix-Gateway or sys-whonix (Qube-Whonix)

1. Change to user clearnet

sudo su clearnet

2. Deactivate uwt stream isolation wrapper by appending .anondist-orig to curl

curl.anondist-org <your_url>

Edit

Note to self: Remove sandboxed Tor Browser link from Whonix 14 release notes

Great! Nits:

Suggestion:

curl is a symlink to curl.anondist. In turn, this symlinks to uwt which runs curl under torsocks. torksocks then forces Tor to run on localhost for stream isolation.

Suggestion:

To use curl:

  • The command must be run under user clearnet.
  • The uwt stream isolation wrapper must be deactivated.

The rest looks good. :slight_smile:

Either run under user clearnet or deactivate uwt steam isolation
wrapper. Either permanently or temporary.

I followed all the steps from the links you provided (in sys-whonix and whonix-gw Template when appropriate) and curl must be run under user clearnet for both temporary or permanent deactivation.

Is this what is expected?

I ran through more testing.

The only way I could run curl from user@host:~$

In whonix-gw Template, run.

sudo nano /etc/uwt.d/50_user.conf

Add

UWT_DEV_PASSTHROUGH="1"

Then.

In sys-whonix run

user@host:~$curl <some_url>

I more question

curl can be run from user clearnet without appending .anondist-org (works)

Should users be warned not to do this even if it seems to works?

Whonix 14:

Have a look at the end what really happens. Only the latest exec calls matters.

uwtwrapper_verbose=1 curl something

Expected:

Using uwt / torsocks / stream isolation.

Result:

exec torsocks /usr/lib/uwtexec something
exec -a /usr/bin/curl /usr/bin/curl.anondist-orig something

I.e. torsocks gets prepended before running curl.


uwtwrapper_verbose=1 UWT_DEV_PASSTHROUGH=1 curl something

Expected:

Not using torsocks / stream isolation.

Result:

exec /usr/lib/uwtexec something
exec -a /usr/bin/curl /usr/bin/curl.anondist-orig something

I.e. torsocks does not get prepeneded. curl gets run as is. No stream isolation. Local connections unhindered. Same effect as running curl if uwt wasn’t installed.

/usr/bin/curl.anondist-orig is the real curl binary. I.e. No stream isolation. Local connections unhindered. Same effect as running curl if uwt wasn’t installed.

Running /usr/bin/curl.anondist-orig directly circumvents all the uwt logic.


I more question

Warn against what?

  • It’s still torified - we could even call this a bug?
  • It’s to be expected to be using clearnet when using Whonix-Gateway and logging in at user clearnet.
  • It’s not something happening by accident.
  • We don’t document this light heartily.

.

clearnet@host:/home/user$ uwtwrapper_verbose=1 curl https://check.torproject.org
exec torsocks /usr/lib/uwtexec https://check.torproject.org
exec -a /usr/bin/curl /usr/bin/curl.anondist-orig https://check.torproject.org

So to reach actual clearnet, one still has to disable uwtrapper(s).

When using user clearnet on Whonix-Gateway and it’s expected to be reaching clearnet.

Thank You!

I’ll get to work adding new steps to permanently or temporary deactivate stream isolation for curl in new /Dev/tech chapter.

That should be already documented, belongs here…?

The rest of my explanations from my previous post may also be a good candidate for copying with modifications to https://www.whonix.org/wiki/Dev/anon-ws-disable-stacked-tor.

No problem. :slight_smile:

I though you might have wanted deactivate stream isolation temporarily and permanently also with https://www.whonix.org/wiki/Dev/anon-ws-disable-stacked-tor

Makes more sense just to add link to

Debugging with curl

Trying to use curl rather than curl.anondist-org is a common mistake when debugging Whonix network issues.

curl is a symlink to curl.anondist. In turn, this symlinks to uwt which runs curl under torsocks. torksocks then forces Tor to run on localhost for stream isolation.

To use curl

  • The uwt steam isolation wrapper must be deactivated
  • The command must be run under user clearnet

In Whonix-Gateway or sys-whonix (Qube-Whonix)

1. Change to user clearnet

sudo su clearnet

2. Deactivate uwt stream isolation wrapper by appending .anondist-orig to curl

curl.anondist-orig <your_url>

Using curl in Whonix 14

curl must be run under user clearnet the same as in Whonix 13

In the following examples, the exec calls from the command output shows the difference between running curl with the uwtwrapper both enabled and disabled.

Example 1

curl is run with the uwtwrapper enabled.

uwtwrapper_verbose=1 curl <your_url>

This results in the following exec calls. Only the latest (most recent) call matters which shows torsocks is prepended before running curl.

exec torsocks /usr/lib/uwtexec something <your_url>
exec -a /usr/bin/curl /usr/bin/curl.anondist-orig <your_url>

Example 2

curl is run with the uwtwrapper disabled.

uwtwrapper_verbose=1 UWT_DEV_PASSTHROUGH=1 curl <your_url>

This command results in the following exec calls which show torsocks does not get prepended before curl. Since curl does not run under torsocks, local connections are not hindered and there is no stream isolation

exec /usr/lib/uwtexec <your_url>
exec -a /usr/bin/curl /usr/bin/curl.anondist-orig <your_url>

The output from the previous commands establish the following

  • /usr/bin/curl is symbolically linked to /usr/bin/curl.anondist-orig. This demonstrates /usr/bin/curl.anondist-orig is the actual (real) curl binary.

  • When /usr/bin/curl.anondist-orig is run with the uwtwrapper disabled all uwt logic is circumvented.

Users can either run curl under user clearnet or deactivate the uwt stream isolation
wrapper either permanently or temporary

Whonix 13 / 14, there is no difference. You always need to run under user clearnet.

Well, it actually depends (but not on 13 / 14).

If you want to reach clearnet -> user clearnet.

For location connections -> any user.
