WSS Connections?

[richardardrichard]

I'm trying to set up a websocket connection to an XMPP server, and can't seem to get it working with TLS no matter how many different configurations I try 😸! Running Tsung with TLS turned off on the XMPP server is working fine, and normal websocket client connections using TLS are also working fine. Does Tsung support wss connections? I can't seem to find this in the documentation, or online anywhere, and any help would be much appreciated.

if you use websocket as a server type, then no, it's not yet supported.

Hasn't this been resolved, @nniclausse? e.g ca0e101 looks like it would implement wss already 😕

[andrewvmail]

i'm trying this too and can't get it to work. I'm confused now if it has been implemented or not yet?

@andrewvmail, @richardardrichard can you share the test configuration XML you've tried so far? I'm personally not very familiar with XMPP but maybe this gives us some more hints where to look.

As mentioned before, ca0e101 implements websocket_ssl/wss as a transport (ca0e101#diff-75ee81b28a58d235f7fd38b27c752170).

hi @tisba here is my config i believe it connects to the server , i see from the server log that something its hitting its websocket endpoint. but its not doing the following xmpp protocol commands defined in the config

Hey @andrewvmail!

1. What version of tsung are you running exactly?
2. Is this all of the error message?

In 1.7.0 ts_server_websocket_ssl.erl line 167 points here https://github.com/processone/tsung/blob/v1.7.0/src/tsung/ts_server_websocket_ssl.erl#L167

I have a theory (Socket can be none), but I cannot really test this out as I don't have access to a XMPP over Websocket/TLS endpoint (and I also don't know much about XMPP). I have pushed a branch with a potential fix: https://github.com/processone/tsung/tree/fix-websocket-ssl-transport.

Could you give this a try?

git clone https://github.com/processone/tsung.git
cd tsung
git checkout fix-websocket-ssl-transport
./configure --prefix="/tmp/tsung"
make install

[andrewvmail]

@tisba

I was using Tsung version 1.7.0
I think there is other error but i don't think thats related to this

But yeath, I make from your branch and that one works.

/tmp/tsung/bin/tsung -version
Tsung version 1.7.1_dev

i see two way comm between Tsung and the xmpp server

[tisba]

Nice! I'll make a proper PR then so that we can get this into develop and maybe even the upcoming 1.8.0 release.

[andrewvmail]

Im just testing this again I think the regular websocket connection stopped working with jabber.

[andrewvmail]

Here is the error message using the develop branch

=ERROR REPORT==== 18-Sep-2018::13:48:21 ===
Error in process <0.15496.0> on node tsung_controller@localmobile with exit value:

                              {line,81}]}]}

[tisba]

I don't think that this error is related. Did you change something else? You said a while ago that the fix did work for you.

[tisba]

@andrewvmail please comment again if you are sure that this issue is caused by the change. As I said, I don't think that the error is caused by #325.

[andrewvmail]

oh missed the first message, i dont remember now. let me try to build and try tsung with the xmpp server. iirc think i was able to poke the server to get it to handshake with the develop build but previously it wont event talk. Ill get back to you.

[andrewvmail]

@tisba #349 will fix the mentioned
