[SOLVED] No ifconfig-eth0 file?

drillsar · 02-06-2017, 05:56 PM

I just installed centos 7 and my networking seems not to be working. I checked to see if ifconfig-eth0 wasn't present. Am I missing something?

Hi,

CentOS 7 uses NetworkManager service, and any more the old network service.
Check and ensure that NetworkManager is enabled and running.

Is this a real or virtual machine?

In addition CentOS 7 uses consistent naming so you should see something strange like enp0s3 versus eth0. what ifcfg-xxx scripts do you see in your /etc/sysconfig/network-scripts directory. Look at the output of the following commands:
ip a

nmcli device status

I tried ifconfig -a says command not found. I will check the network-scripts

I don't think a default CentOS installation includes ifconfig. Mine doesn't.

It does include ip, as michaelk indicated.

Code:

ip addr

will display the sort of basic information that ifconfig -a does.

See man ip for more.

ok after doing ip addr I get:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 some other stuff

2: p4p2: <BROADCAST,MULTICAST> other stuff

What am I looking for?

drillsar · 02-06-2017, 09:35 PM

I have this also:

3: wlp6s0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN qlen 1000
link/ether 18:3d:d0:19:89 brd ff:ff:ff:ff:ff:ff

When I did lspci -v
Kernel driver in use r8169 Realtek RTL8101

I am guessing wlp6so is actually eth0; however, it's DOWN and not giving ip address it seems

drillsar · 02-06-2017, 09:45 PM

I figured it out; duh it was not set to automatic. All good now

wlp6so is a wireless card.

drillsar · 02-07-2017, 12:59 PM

yes p4p2 is my card and the other is wireless. Thanks
