    Has anyone any tips?

    You probably need to set the following in /etc/ssh/sshd_config:

    X11Forwarding yes

    Default is "no"; you'll need to restart the service or reboot.

    Why? Why are you using sudo to ssh into another PC? You should not be
    doing that or allowing root logins across ssh. Bad form. And running an
    X11 as root/sudo, that's not super cool either!

    Here is the real question.

    "Cannot open http://localhost:6544
    Mon Jul 01, 2024 3:36 pm

    This on Mint 21.3 and kernel 5.15.0-112.
    I need to open http://localhost:6544/setupwizard which provides access to MythTV backend.

    It had been working until a series of updates and no doubt,
    changes made made to improve matters ...

    I have checked the firewall and the 6544 is open.

    The bind address in /etc/mysql/conf.d/mythtv.cnf is:

    [mysqld]
    bind-address =*
    max_connections=100

    I cleared Firefox's cache.
    I cannot think of any further steps that I can take. <=== [Uses sledge hammer to cut self a slice of cake :-) ]

    This is sort of the orbit. Either checking status via some webserver
    that displays info about a mysql instance. Or, ssh into the machine
    and give mysql a command directly.

    https://forum.mythtv.org/viewtopic.php?t=3919

    The Arch info, starts in 2015.

    https://wiki.archlinux.org/title/MythTV

    The Ubuntu info, is much older (non-systemd)

    https://help.ubuntu.com/community/MythTV/Install/Troubleshooting#head-75ded5e7682340f0a88f9ed6ec69a68b6a8b4162

    sudo /etc/init.d/mythtv-backend restart

    It seems no one in this club, ever draws a block diagram. Not evar.

    "Unable to connect
    Does '$ ssh -Y alan@origen' work ? "-Y" is like "-X" w/o trust issues.
