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

Dear Simon,
And can you diff the config of eno1 and eno4.
# pwd
/etc/sysconfig/network-scripts
Okay, nothing to find here.
What about eno2, you also have two IP addresses there and even in the same
subnet, is this wanted or not? Can the second address of eno2 be found in
the ifcfg file?
Both eno2 and eno4 have "scope global secondary dynamic" with the second
address and it doesn't seem to come from the base configuration.
