Stable proxy not working #4367

Closed MichaKersloot closed 1 month ago

MichaKersloot commented 1 month ago

Describe the bug Can't get stable version working. Tried on Ubuntu and Fedora

To Reproduce Steps to reproduce the behavior:

  1. install xpra
  2. browse to http://server:14500/

Oh, you better disable SELinux as that will add some issues.

You get and error 400 on http://server:14500/ because certificates are not found: edit /etc/xpra/conf.d/12_ssl.conf change 

ssl-key = /etc/xpra/key.pem
ssl-cert = /etc/xpra/cert.pem

Find you now have a html5 client in your browser if you go to https://server:14500/ connecting to http still shows an error.

Now try to login and get an 'invalid username' error.

edit /etc/sysconfig/xpra (or /etc/default/xpra) change 

TCP_AUTH=sys:client-username=yes,verify-username=no

and now you can for example login with the option 'Start desktop' which really seems to start a new desktop on the server, but brings you back to the html5 login with an 'server closed connection'

On the server you'll find the following error: SocketProtocol._add_packet_to_queue() takes from 2 to 4 positional arguments but 7 were given

And that error seems to be unsolvable for me ;-(

System Information (please complete the following information):

Extra info

I've been into this for some time now, so maybe I've changed a little bit more than stated above, but I don't think so.

Sorry about this. I think that you've hit a number of regressions that are due to be fixed in 6.1.3: https://github.com/Xpra-org/xpra/blob/v6.1.x/docs/CHANGELOG.md#613-2024-09-24 (under "proxy server")

Until this update is released, you may have more luck with the 6.2 beta builds, or the 5.x LTS branch.

Hi @totaam ,

no sorry... After re-reading my post I can see I was a bit frustrated, but I shouldn't show that in my post. I do see you are completely committed to this software and I really appreciate your work!

I do have some questions about this project.

It looks like a mature project with a lot of activity. There also is a lot of documentation, although it's more for the current users than for newcomers like me ;-) It also has a published stable and beta branch. I was just surprised to see the stable branch not working for me. Is that because the proxy part is not used much and somehow got broken by some backport from beta? Or did I got problems because I did not upgrade from an older version and installed it fresh?

I was not aware there is a 5.x LTS branch. Are there packages for that?

Thanks again for you work.

Documentation is very much a continuous work in progress.

Is that because the proxy part is not used much and somehow got broken by some backport from beta?

There were a number of issues, not all of them would manifest themselves with all setups.

Or did I got problems because I did not upgrade from an older version and installed it fresh?

No, upgrades should (usually) make no difference.

I was not aware there is a 5.x LTS branch

This is documented! https://github.com/Xpra-org/xpra/wiki/Versions

Are there packages for that?

They are in the stable repository, which also contains newer builds from the 6.x series, so if you install using a default package manager command, you will get the newer builds.

6.1.3 has been released with all the proxy fixes.
