my Centos7 VPS is using promiscuous mode / rkhunter warning


Since couple of days RKHUNTER report this warning:

Warning: Possible promiscuous interfaces: ‘ifconfig’ command output: eth0: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST> mtu 1500 ‘ip’ command output: eth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000

When i do :

ifconfig eth0 -promisc

and do rkhunter --propupd then the msg is gone. but every time the warning come back later.

What does this mode mean? And how can i disable it on a centos 7 machine?

Kind Regards, Peter
