Hellow Macenger, I send you the content file resolv.conf

# cat /etc/resolv.conf

nameserver 10.26.1.13
nameserver 159.16.10.8
search localdomain

I was try to access a Network configuration in Linux CentOS release 7.3.1611 but the interface sent me the next error messages:

"The system network services are not compatible with this version"

Review network setting, I executed:

#ip addr list:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1

The ip addr virbr0 and virbr0-nic are nor requiered, how can eliminate?, could you help me?, please

I opened the file: vi /etc/sysconfig/network and it's content is:

# Created by anaconda
NETWORKING=yes

And investigate in internet I found the correct configuraction must be:

NETWORKING= yes
HOSTNAME= prueba
GW= the gw adequate

I send you more information, and I hope you can help me, thanks a lot.
