Check-mk-agent.socket ipv4 ipv6 ubuntu 22.04


I noticed, that with the syntax blow, only tcp6 is active and not tcp4

ListenStream = 6556
tcp6       0      0 :::6556                 :::*                    LISTEN      0          1004793    1/init              

if I change the ListenStream to

ListenStream = X.X.X.X:6556

it works

tcp        0      0*               LISTEN      0          1005906    1/init         

the option BindIPv6Only = both does not help …

AFAIK a tcp6 socket is able to handle IPv4

I did fw stuff and changed to many things at the same time …
