NetworkManager liest Konfigurationen aus:

  * /etc/NetworkManager/system-connections/ (Keyfile-Format)
  * /etc/sysconfig/network-scripts/ifcfg-* (Legacy-Support bleibt aktiv)

Beispiel einer ifcfg-Datei
<code>
# cat /etc/sysconfig/network-scripts/ifcfg-ens192
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
IPV6_DEFROUTE=no
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=eui64
NAME=ens192
UUID=35d5897e-9526-4d97-be2e-53eec07da61c
DEVICE=ens192
ONBOOT=yes
IPADDR=172.21.1.26
PREFIX=23
GATEWAY=172.21.0.1
DNS1=172.21.0.3
DNS2=172.21.0.2
DOMAIN=domain.local
</code>

Woher stammt die Config?

<code>
nmcli -f NAME,UUID,TYPE,FILENAME connection show
</code>

=====Logging=====

Standard systemd-[[journald]], [[rsyslog]] scheint aber auch von Haus aus drauf zu sein.
