My guess would be that the switch isn't configured to give you access to VLAN 5 with tagged packets.

Thank you again. I am deploying Liberty Neutron, according the official document, there are two NIC at least, but my physical machine has only one. Someone suggested me I could create a vlan interface, then everything would be ok. Until now, though I created the vlan interface, it can't attach to the Internet. Could other methods created virtual interface instead of vlan interface? Thanks

Hi I have just installed centos 7 altarch on a 32 bit computer. I selected the minimal system install. I see that when I search with yum there is no command system-config-network, i.e. yum search system-config-network Does this command (system-config-network) still exist? Would I expect it to be in the repository even though I did a minimum install? Although I do not have X, I can run some X

Hi, I m using centos 7 in laptop and kvm as virtualization to run windows guest vm.Currently i m using NAT as default setting for guest vm, my internet is fine but can't resolve some domains and sites. So want to come on bridge. As per my understanding bridge can not work while device is managed by NetworkManager. Is there any utility or tool to use to scan wireless device in network and

Hallo, I need the device eth0 for one tool using centos 7.6. Using this tutorial https://www.certdepot.net/rhel7-restore-old-network-interface-name/ doesn t work. Thanks for a hint. Ralf

Hi, I'm currently experimenting with CentOS 7 in order to get a grasp of everything that's new. After having read the FAQ entry on network interface names, I decided to revert to the tradictional interface naming scheme by adding the relevant kernel options to the bootloader. This went well, I have now two interfaces names 'eth0' and 'eth1' as expected. In my office

I have a Dell server that has two built-in ethernet devices. When I kickstart the machine, they are correctly identified as eth0 and eth1 (correctly meaning they correspond to the physical device ports 1 and 2). I need a third one and want that to come up as eth2. After adding the hardware, kickstart now fails because for some reason it goes through a rename process where it makes the newly added

Hello, I'm a little confused on which networking option I need to choose when setting up a VM. I set up two VMs this past weekend both with NAT. Both able to were access the internet. The first one, I created in my / file system but didn't really have the space so I deleted it. The second one, I created in /home/kvm, but deleted it as well when I couldn't access it FROM the

There may be ways to force NIC naming, I've done so but only on Ubuntu so you'll need to do the research if it's important to you. Things to look for based on my experience: 70-persistent-net.rules, net.ifnames=0, biosdevname=0. ________________________________ From: CentOS <centos-bounces at centos.org> on behalf of Nicolas Kovacs <info at microlinux.fr> Sent: Sunday,

Hi, I've done my fair share of CentOS 7 installations, but this is the first time I have this kind of weird problem. Here goes. In my office I have a battered Dell Optiplex 320 PC with two NICs that I'm using as a bare metal sandbox server for testing purposes. The CentOS 7 installer sees the connected network card as eth0. But after the first reboot, the interface comes up as eth1.

I have built a CentOS 8 base image from a kickstart, for use in OpenStack. This image boots fine but the problem I have is that I can't stop udev from renaming the network device from eth0 to ens<something>. I have /etc/sysconfig/network-scripts/ifcfg-eth0 with the correct HWADDR defined in it, and have set net.ifnames=0 and biosdevname=0 in the grub configuration, but nothing I have
