similar to: How to configure DNS server in RHEL 7 / CentOS 7

Hi all, I've recently started using NetworkManger service and nmcli tool, I like it much better than the old network service and manually modifying network scripts. I've seen many online questions on how to disable NetworkManger but I have the opposite question! I am wondering if it be OK to disable network service altogether and just use NetworkManger for configuring and managing Ethernet

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

Hi Neil, Thanks for your comments. What's the purpose of creating spurious ?bond0?? It's confusing. Is it anywhere documented? Every time I restart NetworkManager it creates another bond0!

Hi All, nmcli tool in CentOS 7.1 uses same fields with upper and lower case with different meanings. What's the difference between pv4.addresses and IP4.ADDRESS in "nmcli con show" command? Where nmcli fields are documented? I searched online but didn't find nmcli documentation. RHEL 7 Networking Guide doesn't explain nmcli options in details. I'd appreciate your

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

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?????

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

hello Greg, thanks for the answer, now I am not so alone ;-) this Problem with the third NIC in a KVM Client is from Update to Update stronger. I mean on start the Installation "CentOS 7.0" we don't have this Problem! without NetworkManager is run, on my system, I can't start the third Network- Card, I have always a LSB Error on the KVM-Clients ?? So now I found a

If you do, > and that interface goes down, your DNS config also disappears. I would like to do that very much, only NetworkManager makes you jump through burning loops to do so. With network-scripts, it

Hello, On my systems I have after update to last centos 1810 a big Problem with the network?? Om my system I have three NIC two are connected from hardware (hostdev) the last is connected from the bridge on the host.

Shorewall 4.5.15 3 Interface setup em1 p3p1 p4p4 ppp0 Hi, Since changing to NetworkManger on Fedora 18 I can no longer connect to the DSL Modem, which is connected to Interface em1. When the NetworkManger brings up the interfaces and ppp0, it no longer assigns an IP to em1. If I have ppp0 disabled and NetworkManger brings up the interfaces, em1 gets an IP of 192.168.1.2. Then when I get

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

So, I'm getting an error where the network service and NetworkManager apparently don't agree on how to bring up vlans on bonded nics. Things come up if you 'ifup ..' manually. I thought I'd check if there were any updates, forgetting to fix what NetworkManger had done to /etc/resolv.conf and: http://centos.arvixe.com/7.0.1406/os/x86_64/repodata/repomd.xml: [Errno 12] Timeout
