Dear Simon,
every second IP-address is unwanted. We restarted? eno4:
nmcli con down eno4; nmcli con up eno4
and the second address vanishes. Then after a few ours, the second ip
address reappears.
This is the config-file of eno2:
# cat ifcfg-eno2
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eno2
UUID=cb6fcb54-be52-4ab6-8324-88091a0ea1a0
DEVICE=eno2
ONBOOT=yes
IPV6_PRIVACY=no
IPADDR=10.10.100.205
PREFIX=24
GATEWAY=10.10.100.254
DNS1=10.10.100.1
DNS2=10.10.100.2
DOMAIN=ourDomain
I am not aware of this setting:
scope global secondary dynamic
So maybe you are able to find it in the nmcli output:
# nmcli con edit eno2
===| nmcli interactive connection editor |==
