    Hello all,

    when I run an xpra server on a gentoo box and attach via a client is on
    a nixos box), I get the following:

    /: Permission denied (publickey,password,keyboard-interactive)./
    /2024-09-13 11:04:03,232 Error: failed to receive anything, not an
    xpra server?/
    /2024-09-13 11:04:03,233   could also be the wrong protocol,
    username, password or port/
    /2024-09-13 11:04:03,233   or the session was not found/
    /2024-09-13 11:04:03,233 Connection failed/

    "PasswordAuthentication yes" is left commented out in
    /etc/ssh/sshd_config, i.e. is the default.

    Anyone experience this?

    I don't use Xpra to know its intricacies, but the error message is giving you
    a hint. Some quick things to check for:

    Is there a listening port on the server box as you have specified?

    Is Xpra running on the server?

    Are you binding the correct address, or all addresses, e.g.:

    xpra start --bind-ssh=0.0.0.0:22222 --start=some_app

    Can the user running the Xpra server access the private key? You can set IdentityFile, or make sure the user can access ~/.ssh/.

    Is there a firewall blocking access?

    And finally, increase verbosity and then check what the logs reveal on both ends of the connection, other than the no response message you posted.

    HTH.
