    Hi
    I am having a hard time to figure out how to transfer data via option 21/8 in centmin menu.
    Is ncat suppose to run on both machines? Do I have to run it manauly?
    At which port is it supposed to run?
    I am getting Ncat: Connection refused. no matter what I do.
    I tried default 12345 port, 31337 from the googles idea of default.
    I googled here as well, but transfer info I fond is from 2017
    and the term is quite generic and I was not able to find anything about this option 21.

    thx.

    Nginx 1.31.x
    MariaDB 10.x/11.4+/12.3+
    Does using the centmin.sh menu 21 guide help?
    It would of instructed you to use CSF Firewall to allow both source and destination IP addresses so you wouldn't have connection refused on non-standard ports
