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. # cat /etc/sysconfig/network-scripts/ifcfg-eth1:192BOOTPROTO=none BROADCAST=192.168.255.255 DEVICE=eth1:192 IPADDR=192.168.0.1 IPV6INIT=no MTU="" NAME="LAN - Non-routable" NETMASK=255.255.0.0 NETWORK=192.168.0.0

Hello. I desire to get bridge network working using virt-manager. Centos 7 and centos 7 guest. >From researching I think I need to have a ifcfg-br0 file like this ? cat ifcfg-br0 DEVICE=nm-bridge0 STP=no TYPE=Bridge BOOTPROTO=none IPADDR=192.168.1.8 PREFIX=32 GATEWAY=192.168.1.1 IPV6INIT=no NAME=br0 ONBOOT=yes DELAY=0 Is that for sure needed ? The use that nm-bridge0 as the network name? I

Hi, I accidentally found that the existence of a file e.g. named ifcfg-eth1:1 put in /etc/sysconfig/network-scripts/ leads to the appropriate interface being created even with the option 'ONBOOT' set to 'no': DEVICE="eth1:1" BOOTPROTO="static" NM_CONTROLLED="no" ONBOOT="no" TYPE="Ethernet" IPADDR=12.34.56.78

Hi, I'm trying to configure a network bridge over a bonding without any success.

CentOS-6.6 We have a host that has multiple IPv4 addresses aliased to eth0. The primary address is 216.185.71.x and the alias is 192.168.6.x. This host connects to devices on both netblocks without problems. Only default routing is used and it looks like this: #ip route 192.168.6.0/24 dev eth0 proto kernel scope link src 192.168.6.x 216.185.71.0/24 dev eth0 proto kernel scope link src

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 Interfaces files : [root at localhost ~]# cat

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.

hello all, I have been trying to set-up bridged network with VLAN and not able to succeed as many tutorials address only single NIC. I am trying to setup 2 guests (backtrack instance) each guest has NIC1 and NIC2. following is snippet for guest1 I am not able to get 192.168.0.2 address back on guest eth0.

dear All, I'm facing this routing problem, the setup is actualy part of ltsp, but I think this problem is Centos-specific. The server is a Dell Poweredge R210. The install is standard 6.4, updated. I have one nic facing the public internet: vi /etc/sysconfig/network-scripts/ifcfg-em1 DEVICE=em1 BOOTPROTO=none HWADDR=d4:ae:52:c1:28:2b NM_CONTROLLED=no ONBOOT=yes TYPE=Ethernet

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

Hi all, we are testing CentOS 7 in order to migrate from Scientific Linux 6 / CentOS 6 and we are facing an issue with the network. Trying to configure network with teaming in activebackup mode or also with bonding in mode=1 (active backup as well) we see many RX dropped packets in the bond0 interface (around 10% of the total), 100% RX drops in the backup interface and 0% in the active interface.

Weird behaviour. A couple of days ago I installed another DSL router. During the process I have somehow caused the default gw route to disappear - on system start up the interface comes up fine, I can see and connect to the local subnet but not to the internet.

H? all; i need your helps on setting the virtual ip. I am trying to setup static virtual ip on CenOS7. but I want my VIP to should not open when rebooting. My interface settings like this: *for ens33 NIC -> ifcfg-ens33* DEVICE=ens33 BOOTPROTO=none ONBOOT=yes PREFIX=24 IPADDR=192.168.2.151 *and for VIP NIC ens33:2* * -> ifcfg-ens33:2* DEVICE=ens33:2 ONBOOT=no ONPARENT=no

This is happening with the Centos7-armv7 image 1804, but I was wondering if it is a broader C7 issue. My image has only 2 ifcfg files:? ifcfg-l0 and -link.? 'ip a' is listing the ethernet as eth0.? ifcfg-link has contains: DEVICE=link BOOTPROTO=dhcp ONBOOT=on I then used nmcli to create my ifcfg-eth0 nmcli con delete eth0 nmcli con add type ethernet con-name eth0 ifname eth0 ip4

Here is my script for post install if you want to try it. In order for the shuffling to not occur you do need to create the udev rules file somehow. I am not sure how mangled this will be in email but it is worth a try. It should run OK with nothing else. I have a better version in the works but the enhancements are mainly useful for Fedora 19-21. I did forget to say I also block
