How is that better than systemctl stop NetworkManager systemctl disable NetworkManager Again, I?m not really after a way to make this work without NetworkManager. We?ve already got that. What I want is a way to tell

If you configure a static IP with the wired Ethernet plugged in, you probably want that static IP to continue being used when you unplug the Ethernet cable and NM

Hi, I'm running CentOS on all kinds of setups: servers, workstations, desktops and laptops. Up until now, I'm only using NetworkManager on laptops, since it makes sense to use it there. On servers and desktop clients, I usually remove it and configure the network "traditionally" by simply editing /etc/sysconfig/network-scripts/ifcfg-whatever, /etc/resolv.conf, /etc/hosts,

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. (NetworkManager was disabled) Now after the update the client can't start the NIC's correctly :-( My Problem is the bridged NIC ethX I must Install and activate the

Hi all, I have a CentOS 5.4 server-only installation, i.e. no X installed, and for some odd reason /etc/resolve.conf gets overwritten by NetworkManager on a constant basis. I haven't been able to track down how often, but I think it's on the hour, or something. This is the conents of the file right now: # Generated by NetworkManager # No nameservers found; try putting DNS servers into

On my CentOS 6 partition of my laptop: First note that for this test, NetworkManager is not running because I did: chkconfig --del NetworkManager and then rebooted.

Hi, I'm just migrating some stuff from Slackware Linux to CentOS, and I have a question about the orthodox way of configuring a network connection. On a desktop or workstation, I usually get rid of NetworkManager: # systemctl stop NetworkManager # yum remove NetworkManager Then I edit the /etc/sysconfig/network-scripts/ifcfg-XXXXX file corresponding to my network interface.
