Hi, I encountered a problem when creating a VLAN interface according to the Red_Hat_Enterprise_Linux-7-Networking_Guide. I configuered the parent interface ifcfg-eno1 as follows: DEVICE=eno1 TYPE=Ethernet BOOTPROTO=none ONBOOT=yes And I created a new file named ifcfg-eno1.5, the content is: DEVICE=eno1.5 BOOTPROTO=none ONBOOT=yes IPADDR=192.168.81.3 PREFIX=24 NETWORK=192.168.81.0 VLAN=yes T...

Incidentally Mark, this had nothing to do with systemd ... I wish you would pick your topics a little more appropriately rather than tempting the usual flames.

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.

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

...t 2 = eth1, and the additional ethernet card then becomes eth2? What version of CentOS are you trying to install? I would expect that a recent version would use the biosdevname interface naming scheme on a Dell server. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/sec-Consistent_Network_Device_Naming_Using_biosdevname.html -- ======================================================================== Ian Pilcher arequipeno at gmail.com -------- "I grew up before Mark Zuckerberg invented friendship" -------- ===...

...ed to go with NAT or bridged? You have a couple of options for VMs that you want to access from the LAN. The best documented and probably most widely used is bridged.

...work is on NetworkManager. Note as well this article was last updated in 2014 - NetworkManager has been updated to handle more use cases than back then. As always it's best to check with the upstream documentation: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/index.html Finally there was nothing to do with IPv6 in your article. That address was an IPv4 address and the zeroconf stuff configures the 169.254.0.0/16 network as a 'local link' network on that interface. If it was IPv6 it would have an address like fe80::33bb:5a14:be57:1690/64 ... w...

Hi We are trying to configure RDMA for an infiniband connection between our data server (running CentOS 6.8) and our compute nodes (running CentOS 6.6).? We have been trying to follow the instructions in https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-configuring_the_base_rdma_subsystemedit however we are getting conflicting information on whether the RDMA is correctly configured.??? Some of what we have done and some of the data are below. Can you suggest what other tests and what other data we should get to debug this problem? /etc...
