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

Poor perfmance of bridged interfaces
Hi,
I've created a bridge using 2 interfaces and have a lot of messages as
follows:
nov 12 15:30:22 localhost kernel: br0: received packet on enp0s3 with own
address as source address
nov 12 15:30:22 localhost kernel: br0: received packet on enp0s3 with own
address as source address
And the operating systems is extremely slow

Can anyone tell me why I am seeing these error message?
Specifically, why is TYPE=Bridge giving Unknown connection type

Set static IP
Hello,
I want my CentOS 6.5 computer to have a static IP. Currently I get the
IP I want because I have my router assign it on the basis of mac address.
I placed the following file as:
/etc/sysconfig/networking-scripts/eth0
DEVICE="eth0"
BOOTPROTO=static
HWADDR=00:1F:D0:9E:AE:67
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
NETMASK=255.255.255.0
IPADDR=192.168.0.99

CentOS 5.7 Ethernet bonding - order of enslavement matters?
Setting up bonding in active-backup mode 1 (using ARP monitoring)
on a server, it looked OK, but pulling the active link cable
didn't actually work, it didn't fail over.
Eventually with manual playing around with modprobe, ifconfig,
ifenslave, etc., a solution was stumbled upon: enslave the eth1
device before eth0, and all is good.
Why this should matter is a puzzle - I could not find

nmcli: unwanted secondary ip-address
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

Network configuration: desktop vs. laptop
Hi,
I'm just migrating some stuff from Slackware Linux to CentOS, and I have
a question about the orthodox way of configuring a network connection.
On a desktop or workstation, I usually get rid of NetworkManager:
# systemctl stop NetworkManager
# yum remove NetworkManager
Then I edit the /etc/sysconfig/network-scripts/ifcfg-XXXXX file
corresponding to my network interface. Here's

Using Puppet to swap eth0 and eth1
I''ve been using Puppet now for a month or so and I''ve come to a
problem that may warrant an additional Puppet metaparameter. I''m
advocating the addition of a metaparameter called "preaction" (or
something like that), which will perform some arbitrary action before
the resource is modified. There may be a way to do this within
Puppet already (with some

CentOS 6: ethernet "ifconfig up" failure
On my CentOS 6 partition of my laptop:
First note that for this test, NetworkManager is not
running because I did:
chkconfig --del NetworkManager
and then rebooted.
Here is my ifcfg-eth0:
DEVICE="eth0"
NM_CONTROLLED="no"
ONBOOT=no
HWADDR=xx:xx:xx:xx:xx:xx
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.2.5
PREFIX=24
GATEWAY=192.168.2.1
DNS1=192.168.2.1

Simple IP Question
I have a server located remotely running CentOS 5.x. I need to have
two IP's on the same interface. So I have this:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
BROADCAST=69.x.x.199
HWADDR=00:x:x:x:c6:10
IPADDR=69.x.x.194
NETMASK=255.255.255.248
NETWORK=69.x.x.192
ONBOOT=yes
GATEWAY=69.x.x.193
TYPE=Ethernet
So I added this:
