For the record - I figured this out so am sharing the result for posterity: The issue was that I didn't follow the instructions literally. Since, once booted, my primary NIC name was "em1" I assumed I had to create an initscript called ifcfg-em1 rather than ifcfg-eth0 as described in the doc. Once I renamed that script to ifcfg-eth0 (and changed the DEVICE value in the file to

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 Clint, systemd-networkd doesn't use those files at all.

Hi, I have a few identical Dell Optiplex 7010 machines that I want to use for our school's computer room. I tried to clone these installations (like I did before on CentOS 5 and various versions of Slackware), but this time I ran into a problem. Here's what I did. 1. Install one computer and zero unused hard disk sectors with dd. 2. Send the image to a local FTP server using G4L

We just got DELL R920 and installed Centos 6.5 on it.? After installation, network not function.? We manually enter IP address, gateway and netmark on "em1".? we also do following: 1. startup NetworkManager 2. /etc/sysconfig/network-scripts/ifcfg-em1? ==> NM_CONTROOLED=yes I tried to startup network and get error message: Bring up interface em1: connection activation failed

Hello everyone I am running into some strange issues when configuring networking interfaces on my physical server running Centos 7.5. Let me give you an overview of what's going on: We have a physical server, running CentOS 7.5. This server has one 4 port NIC and one 2 port NIC and a Dell IDRAC port. The first port of the 4 port NIC, em1, is used for Management traffic. The first port of

Sometime in the past two weeks, Some kind person pointed me to a GREAT document file that explained all those commands you find in the ifcfg-* files and the network file (and others, I believe). It was a great help to me, and now I need it again, and I did not write down the file location, nor can I find that original note. My bad, I am busy documenting everything I can now. But I really

My manager tells me a system in the datacenter is down. I go down there, and plug in a monitor-on-a-stick and keyboard. It's up, but no network. I try systemctl restart NetworkManager several times, and ip a shows *no* change. Finally, I do an ifdown, followed by an ifup, and everything's wonderful. My manager thinks that the NM daemon thinks everything's fine, and there've been

Hello All, I seem to have run into a bug with the new --bridgeslaves=<INTERFACE> option. It would seem that if I tell the bridge device to use a virtual interface (like bond0) rather than a physical interface (em1/em2) that kickstart completely barfs on it. I have provided my network section below which works fine as long as i don't enable all the bridge content. When the

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

Hi all, Having a 4 NIC server, I want to bridge eth2 and eth3, with a bridge named br0. Searching the web I only found about creating a file /etc/sysconfig/network-scripts/ifcfg-br0, but did not find where to explicitely list what ports will be bridged. Where is it configured? Thank you. -- RMA.

Hello, I've setup a VM with default networking (NAT) and this works fine but hosts on my LAN can't get to the VM since it uses NAT. When I try to set network to use MacVTap with either default or bridged I get no networking for the VM. Any hints around this? I would like to have the VM's on the same LAN as my host and other machines. I don't care if the VM host can't reach the

Hi, If I disable ipv6 via the kernel command line, ipv6.disable=1, then systemd-networkd fails to bring up any interfaces. Removing the option and networking works as expected. Phil.

Hello I have a virtual server with 3 existing VMs running on it without issue. The host has 4 NICs installed; em1 for the host, em2 and em3 already in use by other VMs. I would like to dedicate em4 to my new VM however when I create the bridge like I did for the others I do not get a vnet3 device show up in the list as shown below. I tried using the GUI and virsh to create the bridge. I ended
