FluffyChat Encryption via Pantalaimon

jonius · 27 Jul 2020, 11:11

It works here on my Pinephone. Does the Pantalaimon app display something like pantalaimon start/running, process 1234?

lgtrombetta · 27 Jul 2020, 14:42

@jonius yes.

I just realized using top via ssh that the process keeps respawning and changing its pid every 5 seconds. Is this behaviour expected? This is on both devices.

thrrgilag · 27 Jul 2020, 14:47

@lgtrombetta If it keeps respawning it means it's failing to start properly.

@thrrgilag worth trying the previous binary (spawned via adb or ssh) rather than the .click?

thrrgilag · 27 Jul 2020, 18:39

@theare27 good thought.

@lgtrombetta if you could try ssh or adb to the device and run it directly, that should hopefully make more apparent what the failure might be. You can do "stop pantalaimon" to make sure the service is stopped, followed by executing "/opt/click.ubuntu.com/pantalaimon.thrrgilag/current/pantalaimon"

@thrrgilag so it finally works. What I found running it as you suggested is that the homeserver address in the config must have the "http(s)://" prefix. While I had added it at some point during my testing, it turns out it must be there for all homeservers in the config in order for the service to start properly, and in my case it wasn't.

So, I feel a bit stupid, but I hope all of this can help to make the UX smoother

Awesome, glad you were able to get it sorted.

I very much appreciate your testing it out. This is the kind of feedback I was hoping for to make it better. Adding to my list of things to fix.

Out of interest, did you get anywhere with the issue with images?

thrrgilag · 28 Jul 2020, 18:07

@theare27 not really, it seemed to be something to do with how fluffy was sourcing the image url, I found this bit in the logs..

QHttpNetworkConnectionPrivate::_q_hostLookupFinished could not de-queue request, failed to report HostNotFoundError
file:///opt/click.ubuntu.com/fluffychat.christianpauly/13.2/qml/components/Avatar.qml:30:13: QML QQuickImage: Host http not found

Haven't gone any deeper than that. Whatever the issue is though it seems specific to FluffyChat, other clients I've tested through pantalaimon (uMatriks on UT and Fractal on others) don't have that issue.

theare27 · 28 Jul 2020, 19:07

@thrrgilag Hmm, so I might be better off with uMatrix? I know it's unmaintained, but FluffyChat seems to be focusing more and more exclusively on the flutter version these days

thrrgilag · 28 Jul 2020, 19:17

@theare27 I hope that once I get to the root of the problem I can submit a patch to FC to resolve it fully. That is once I get the time to, the day job has me pretty busy right now. If nothing else maybe bouncing between the two clients will suffice unitl a fix can be found.

theare27 · 28 Jul 2020, 19:37

@thrrgilag cheers, yeah I can bounce around when I need to see media until Fluffy Chat gets patched. Thanks for all your work

Hello, i've been struggling to install pantalaimon on my oneplus one, but now it's properly installed (thanks to your click image, great job btw).

Now i think i've found an issue : my homeserver has a .noho.st domain name (Yunohost free domains), and i think pantalaimon does not agree with it : it keeps deleting the stat the end so it fails to connect to it...

thrrgilag · 3 Aug 2020, 13:17

@Aristid can you share the log for it?

Aristid · 3 Aug 2020, 13:25

@thrrgilag http://paste.ubuntu.com/p/3BkPFqBmD5/

notre sure if those are the right ones...

thrrgilag · 3 Aug 2020, 13:31

@Aristid Yeah that looks like the right log, it's just now giving much to go on unforunatly. When you close and re-open the app it does it still remember your configuration?

Aristid · 3 Aug 2020, 13:37

@thrrgilag Well the first time i configure my home server, quit the app and relaunch it the url is truncated (st from .noho.st is removed as mentionned earlier). I complete it again, save and quit and then it appears correctly. But i doubt the app really remembers it as fluffychat behaves as if pantalaimon is not installed.

thrrgilag · 3 Aug 2020, 13:52

@Aristid the actual config file can be found in /home/phablet/.config/pantalaimon/pantalaimon.conf, you can manually verify it's precence there. A couple of other shots in the dark to try is manually look a the config file and make sure your homeserver entry is a full URL, (e.g. https://<whatever>.noho.st). If your SSL cert isn't verifiable you could also try adding "SSL = False" to disable verification of the certificate. You can restart the service by toggling it off & on in the app or but running "stop pantalaimon" and "start pantalaimon" in the terminal.

I'll add some additional configuration items to the next release to help with troubleshooting.

Aristid · 3 Aug 2020, 14:26

@thrrgilag Well config file seems ok, but still cannot read my encrypted chatrooms... When i want to activate the encryption in Fluffychat nothing happens.

thrrgilag · 3 Aug 2020, 14:29

@Aristid is it old messages that you can't read? Do new messages in those encrypted chat rooms work?

One of the limitations currently is that encryption keys aren't imported/sync'd so you won't be able to decrypt anything that was previously sent. New messages should be fine though.
