If you are running NetworkManager (the default), it's not too hard.

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup: ____ ____ / VM1\______br0_______/ VM3\ \____/ | \____/ | _|_...

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.

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

I have a physical host with a single physical network adapter. I want to host several VMs on host. (guest1 - guest4) The guest systems are accessible via 192.168.122.* as is the default with qemu/virsh. There are 4 IP addresses being routed to the primary interface on host. I can set up an alias for the NIC and "see" these ip addresses. I understand that it's possible to allow

...nge 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 the 2 port NIC, is used for the second port in the NIC bond, device p6p2. The second port on the 4 port NIC, device em2 is the first, port on the NIC bond. These interfaces are using Static IPs. Here is my /etc/sysconfig/network-scripts/ifcfg-e...

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 installation starts off the creation of bond0 and all VLANs on bond0 go without issue. Jumping into TTY2 I can type 'ip a'...
