[gentoo-user] xpra server on gentoo? Any gotchas?

Hello all,

when I run an xpra server on a gentoo box and attach via a client  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.
