Bisq - The P2P Exchange Network

Second observation:

When I run a second Bisq instance and I try to take the offer that I make in the first Whonix workstation (the one where the Whonix gateway is on debut), I do not see any messages at all in the debug console.

But if someone (me) is connecting to Tor address in the Bisq instance, inside the Whonix Workstation, running on the Whonix Gateway, then… shouldn’t I see some evidence that it is trying to connect?

The second Bisq instance says that

You cannot take that offer because the maker is offline.

This is the error that everyone is getting recently using Bisq on Whonix. I have the debug window open (explained above), so what more can I do to help debug this?



It was tested a long time ago. See this forum thread. I didn’t re-read all posts. But if you want to pick this up, please read the full forum thread.

Folder /usr/local/etc/onion-grater-merger.d/ is persistent even in an App Qube because it’s in /usr/local. See Qubes-Whonix ™ Overview chapter Qubes Persistence in Whonix wiki.

No. The script is idempotent.

No. That would be Microsoft Windows style “re-install Windows”. Hopefully on Linux such crude fixes aren’t required.

Best to look at the short source code of /usr/bin/onion-grater-add and/or run the script in verbose mode (xtrace).

sudo bash -x /usr/bin/onion-grater-add 40_bisq

It creates a symlink to /usr/local/etc/onion-grater-merger.d/.


Also onion-grater journal log will show which profiles are load.

The actual file created by onion-grater-merger which will be consumed eventually by onion-grater is


No. The kernel will eventually but that’s very low level and very most likely not something to worry about.

That’s Qubes-Whonix-Gateway internal IP. Reachable from Whonix-Workstation.

This most likely won’t be the issue. onion-grater is generally functional. Whonix-Workstation is redirected to Whonix-Gateway. (anon-ws-disable-stacked-tor)

Tor ControlPort

That’s most likely different. That’s the Onion Service port.

No. And it doesn’t need to because the one is Tor ControlPort the other is the Onion Service port.

Try something simpler first. Some other application that uses the Tor control protocol. Something that isn’t complex or broken.

Inside Whonix-Workstation:

tor-ctrl signal NEWNYM

That Tor control protocol command should then be visible on Whonix-Gateway with onion-grater in debug mode.

You would probably need to learn a few components beforehand.

  • Setting up a “normal” Onion Service as per Onion Services - Whonix
  • Interacting with the Tor control protocol generally.
  • Opening a Tor Onion Service using add_onion using Tor control protocol. (Maybe enough if understanding this in theory.)
  • Interacting with the Tor from Whonix-Gateway.
  • Interacting with the Tor from Whonix-Workstation.
  • onion-grater debug mode, log watching for functional things.

On which IP / port is Bisq listening inside Whonix-Workstation?

Does Bisq still use the Tor control protocol to create its Onion Service?

Does Bisq require an Onion Service nowadays?

No, with whonix-gw as network qube the inbound connection do not get through. As inbound connections are required for Bisq to run properly, I had to completely abandon Whonix.

I’d love to see Bisq work on Whonix, but the instructions on the Whonix Wiki simply don’t work.

Yeah those instructions suck in every way. That’s why we’re debugging this. And it used to work last year, so something changed and so maybe it can be fixed.

Any progress?

No. And none should be expected, unless contributed.

bisq signing key recently changed. I couldn’t find any explanation for the change.

An anonymous wiki edit was suggested to update the signing key.

Might be fixed at least for Bisq version 1.x.

The Bisq wiki page has been recently updated. (changes: Bisq: Difference between revisions - Whonix)

See the wiki page here:

  • Version 1.9.14: has been reported to be functional.
  • Version 1.9.15: might be broken but I only got 1 report for that. Still worth trying.
  • Version 2.x: Not worth bothering with until/if above tickets are updated, unless you are a developer.

Please test.

Seems to be broken: [StartTor] Couldn't connect to Tor. net.freehaven.tor.control.TorControlError: Error reply: Command filtered

Error message may indicate an Onion Grater problem. Would require further testing to see what command is being sent.

Did some further digging.

This is the command being sent to Tor control port GETINFO status/bootstrap-phase

Then reply received: 510 Command filtered

That command happens after a bit of other back and forth control commands.

Seems to have done the trick. I attempted something like this but did not add the response pattern and it hung because of that by the looks of it.

The fixed onion-grater profile is now available in all Whonix repositories.
