If you are using ethernet (and not a wireless device or some other internet connectivity) you should have an ifcfg- file for the interface.

Hi All, I see an unexpected beahviour from NetworkManager on CentOS 7.1. Using nmcli tool, I create a bond with two slaves as explained in the Red Hat 7.1 Networking guide. I enable slaves and master; bond works as expected. When I restart NetworkManager, it creates a new bond with the same name but not connected to any device. Two bonds with the same name is confusing for my other monitoring

Greetings, One of my biggest frustrations with CentOS 7 has been firewalld. Essentially all of the documentation just flat doesn't work. One common thing that needs to be done is to change the zone of an interface, however I've tried: firewall-cmd --permanent --zone=internal --change-interface=ens192 firewall-cmd --permanent --zone=internal --add-interface=ens192 I've also tried

You could say the same thing about computers in general: I hate them, they automated many tasks in life and took many jobs out of the market!.

Once again I am building a headless Centos 7 box that needs to reliably be on both the LAN and WIFI network at all times. Amongst other things it's going to be an AirPrint bridge enabling IPads to print to printers on a different VLAN. I have asked about this before and got a solution working using nmtui to set up both the LAN and WIFI interface, and activate them. However, the WIFI

Dear Simon, every second IP-address is unwanted. We restarted? eno4: nmcli con down eno4; nmcli con up eno4 and the second address vanishes. Then after a few ours, the second ip address reappears. This is the config-file of eno2: # cat ifcfg-eno2 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes

I wasn't sure what to call this in the subject line, but here's my issue. I have an occasional need to switch a few computers from one Internet provider to a different one. Both Internet providers feed into the same network, one at 192.168.0.1 and the other at 192.168.0.254. So to change from one provider to the other I run nmtui to change the gateway and dns server addresses, then

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

Hello All, on the latest installs I've done, on 2 different types of Latitude laptops, with 3 different wireless cars, of Centos7 and Mate desktop, it looks to me like NetworkManager is nog managing wireless. When clicking the nm icon in the top right corner, I'm not seeing access points. Wifi seems enabled [root at localhost ~]# nmcli g STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW

Dear CentOS-Community, we are facing the following issue: A secondary ip address seems to be automatically added to a nic which causes several issues in our setup. This server is equipped with four nics which are currently in use: # nmcli con show NAME????? UUID????????????????????????????????? TYPE????? DEVICE eno2????? cb6fcb54-be52-4ab6-8324-88091a0ea1a0? ethernet? eno2 eno4?????

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
