Before running xpra, I have already set up tunnel at port 34021, I can connect 34021 via ssh.

totaam commented 6 months ago

Run with -d ssh to get more ssh debug messages. Or if the problem comes from paramiko, try with --ssh=ssh

But I can connect via ssh directly.

totaam commented 6 months ago

How about without --ssh=ssh? What's the output then?

Are you sure there is an active xpra server on :100? (try xpra version :100 on the server, or just xpra list)

Host key verification failed.

That's not right. This log output looks messed up. This message comes from the paramiko (default) backend, yet you're using --ssh=ssh. Very odd. https://github.com/Xpra-org/xpra/blob/006b7775999a3f72ceb5886d0b4fd4a4dceb624f/xpra/net/ssh/paramiko_client.py#L526

Then there's also the question of the double tunnel. Why use ssh over a tunnel? Isn't that redundant? Why not use plain tcp then?

cadem commented 6 months ago

Very odd, I run xpra_cmd.exe at same machine, but I got error. the error message say: "this application cannot run at the machine." xpra_cmd.exe can run at this machine before.

totaam commented 6 months ago

Maybe an anti-virus has quarantined a file, or system permissions prevent you from running it.

cadem commented 6 months ago

I can not run at my machine, I move to a virtual machine(which is windows server), run C:\Program Files\Xpra\Xpra_cmd.exe" -d ssh attach ssh://ubuntu@127.0.0.1:34021/100

And I got another popup error message: opengl acceleration fature.

I am sure I have sesion on server, run xpra list, I got:

❯ xpra list
Found the following xpra sessions:
/home/ubuntu/.xpra:
        LIVE session at :100
totaam commented 6 months ago

LIVE session at :100

OK, good.

ssh server OS is 'linux-gnu'

The client correctly detects that the server runs Linux.

`adding xpra_cmd='/usr/bin/xpra'

And it finds xpra in /usr/bin.

But for some reason, this command never returns:

channel exec_command('"/usr/bin/xpra" "_proxy" "100" "--env=SSH_AGENT_UUID=737ff26eab3bf56b4905fe3f1e74b8025c4fb836359b40542b47008b0a4b6f22"') (...) connection timed out

That's odd seeing that :100 is LIVE. You could try running it by hand from an ssh session on the server: xpra _proxy 100. Then press enter a few times and the command should exit with an error message:

$ xpra _proxy :100

disconnect: invalid packet header byte: 0x0a

My guess is that perhaps your server version is too old? You haven't specified it. Be aware that the one from the Ubuntu repositories do not work: https://github.com/Xpra-org/xpra/wiki/Distribution-Packages-Ubuntu
