  • [gentoo-user] xpra permissions

    Hello all,

    I'm trying to run xpra as a server on a gentoo box but I get the
    following error on connection:

    /user@host: Permission denied (publickey,keyboard-interactive)./

    My nixos client works well with nixos servers, just not gentoo servers. 
    I don't find a use flag that looks relevant, but maybe I'm overlooking something?

    TIA.

    Check the content of .ssh/authorized_keys and the file's permissions. Perhaps they need adjusting?

    Thank you, that gave me the hint I needed for the first step ... I use
    an ssh option for nixos that's not need for gentoo: /"-o PreferredAuthentications=password"/

    But now I've got a new problem (or problems) that might be gentoo-related:

    /Warning: XDG_RUNTIME_DIR is not defined
     and '/run/user/1010' does not exist
     using '/tmp'
    server socket for display :2 not found

     waiting up to 20 seconds

    xpra initialization error:
     cannot find live server for display :2
    /

    $XDG_RUNTIME_DIR *does* exist, on the server and the client.
    /run/user/1010 exists on the (nixos) client, but there's no /run/user on
    gentoo (that I can see). Therefore, my $XDG_RUNTIME_DIR is set to
    ~/.xpra, which is present and rwe by the user, as is ~/.xdg/xpra. 
    There's a ~/.xdg/xpra/2/socket with a recent timestamp.  There's nothing relevant in /tmp on the server or the client.

    Clearly related is this, when I try to stop xpra on the server:

    /$ xpra stop
    xpra initialization error:
     cannot find any live servers to connect to/
    /
    /
    /$ ps -ef | grep xpra
    user   2544     1  0 09:58 ?        00:00:01 /usr/bin/python3.11

    You can use a user password to login over SSH or public key. It is a matter
    of configuring the sshd accordingly and using either method from the client.


    But now I've got a new problem (or problems) that might be gentoo-related:

    /Warning: XDG_RUNTIME_DIR is not defined
    and '/run/user/1010' does not exist

    I don't know anything about xpra, but the error points to a user account not being available/configured correctly?

    Have you tried connecting locally on the server with no user (you'll be
    already logged in), before you try connecting from the client remotely using the correct user@host incantation?

    Yes.

    I'm thinking it has to do with the configuration of the configuration
    files, as used by both server and client, locally and remotely.



    Have you tried connecting locally on the server with no user (you'll be already logged in), before you try connecting from the client remotely using the correct user@host incantation?


    That was a good idea, logging in locally.  I got the same error, though.

    It was anonymized.
