MBCDN

Der alte network Dienst läuft meißtens gar nicht mehr.

# systemctl status network
Unit network.service could not be found.

Alma Linux verwendet standardmässig den NetworkManager

NetworkManager liest Konfigurationen aus:

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

Beispiel einer Legacy-ifcfg-Datei:

# cat /etc/sysconfig/network-scripts/ifcfg-ens192
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=eui64
NAME=ens192
UUID=1c14d49c-3673-4986-b92f-04f7ddee048f
DEVICE=ens192
ONBOOT=yes
IPADDR=172.21.0.2
PREFIX=23
GATEWAY=172.21.0.1
DNS1=172.21.0.1
DOMAIN=domain.local

Woher stammt die Config?

nmcli -f NAME,UUID,TYPE,FILENAME connection show

Der Dienst firewalld ist Standard in Alma Linux.

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