Omemo fingerprints empty #151

Closed kopfteil closed 7 years ago

kopfteil commented 7 years ago

Hi,

I can't get Omemo to run on my server. I have two separate machines with gajim 16.6 on each of them and a prosody server (also tried openfire and ejabberd) and i finally managed to get the OMEMO icon to even show up in the chat window. Before i got errors related to no finding the client list:

01/04/2017 23:59:09 (W) gajim.plugin_system.omemo somehost => No devices for milpstein@somehost

Now the button shows up but the there are no fingerprints, the windows are empty and only show their own fingerprint. How do i solve that?

Writing test messages between the users does not change anything.

The server does however use some selfsigned certificate, but that shouldn't interfere?

Starting gajim with -l gajim.plugin_system.omemo=DEBUG yields the following output:

frist check the icon and see if the checkbox is activated then try and write a message look at the log output right after writing the message

lovetox commented 7 years ago

you sent me a log output but milpstein@somehost is not in there

lovetox commented 7 years ago

Also a log from both machines would be good, on the one you just posted everything looks good

kopfteil commented 7 years ago

Hi lovetox, I will post the logs of both sides later today.

frist check the icon and see if the checkbox is activated then try and write a message look at the log output right after writing the message

This does not work since there are no fingerprints in the fingerprints submenu for me to trust, it's simply empty and contains only the own fingerprint.

lovetox commented 7 years ago

thats expected, fingerprints in the window will only be pulled from the server when you actually try to send a message.

if the pull from the server doesnt work after sending the message, it will show in the logs

I was just getting ready to take screenshots for you as i started the same setup with prosody and the clients that i used the last two days to no avail, suddenly the fingerprints show up in the menus, even on conversations. It all works now. I absolutely can't tell why it works now and didn't yesterday, but i'll go with that.

So i guess this can be closed. Thanks for your time.

@kopfteil from my experience, i didnt find a bug with publishing and getting keys/devices for a long time.

if it doesnt work in the future, i would say you gain more if you try and see what is published on the servers nodes and if the server really sends this stuff to other clients. watch the xml at startup. the process of publishing and getting keys for the client is pretty easy and not so error prone.

but often the servers just dont propagate updates to other clients, im sure there are still some bugs to discover serverside
