Centos7: Intel nuc/Linksys usb-ethernet
Hello All,
I'm installing some DIY routers, composed of Intel nuc's ,Linksys usb-ethernet adapters and Centos7
On most machines I just plug in the usb device, install Centos7 and everything works.
But on this one machine the network interface doesn't work.
After installing ip addr shows:
[root at clgmol ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue

Simple routing question
We use a dual homed CentOS-6.3 host for our Internet gateway router.
Its internal nic (eth1) is configured such that the address
192.168.0.1 is one of its aliases.

BROADCAST=192.168.255.255
DEVICE=eth1:192
IPADDR=192.168.0.1
IPV6INIT=no
MTU=""
NAME="LAN - Non-routable"

Centos 7 - "Device eth1 does not seem to be present, delaying initialization".
Hi All :)
I have three servers, all with centos 7 installed 3 days ago. I need on
them "old" naming scheme (ethX) for network interfaces, because of that:
# grep GRUB_CMDLINE_LINUX /etc/sysconfig/grub
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_node-XY/swap rd.lvm.lv=centos_node-XY/root
rhgb quiet ipv6.disable=1 net.ifnames=0"
net.ifnames=0 was added and afterwards I ran:

RPC server not available when windows client attempts to join samba AD
I am installing a new Samba 4.2 Active Directory server on CentOS 7. I
followed the Wiki instructions on how to create the server. I am using
sernet-samba 4.2 binaries. Everything seems to be OK on the Linux side but
I cannot get any windows client to successfully join the domain. Each
attempt returns the following error message "RPC Server in not available".

Pasted below. V6 definitely works. I have a second server and gave it a
WAN address and I can connect between them using their WAN addresses.
That's what told me that my ip6tables weren't screwed up and that the
problem lay elsewhere.

That's really interesting. Doesn't NetworkManager also store other
settings in a different location, not the ifcfg files? I think it does so

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"

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:

From network-scripts to NetworkManager on a router : questions
Hi,
I'm running CentOS 7 on all my servers, in three different contexts :
1. simple local server
2. public facing server
3. router/gateway/firewall
I'm currently in the process of moving my KISS-style
network-scripts-style configurations to something more orthodox based on
NetworkManager.
Scenarios (1) and (2) caused no problems, but (3) is giving me some
headache. Let me
