systemctl restart network.service - not start, how to diagnostic?

Post by Windows » 2021/06/18 01:12:36

Hello,

if we run systemctl restart network.service then server lost connection and NEVER is possible reconnect.

we can't use NetworkManager.service becouse "SW to install" only run over network.service

how we can find the "wrong CONFIG" ?

Thanks

this is CentOS Linux release 8.4.2105
