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. Here's

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?????

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.

With network-scripts, it

Used steps on sysctl from?Centos7 FAQ (https://wiki.centos.org/FAQ/CentOS7)?and some gathered on internet # cat /etc/sysctl.d/90-disable_ipv6.conf? net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1 net.ipv6.conf.eth0.disable_ipv6=1 net.ipv6.conf.eth1.disable_ipv6=1 net.ipv6.conf.all.use_tempaddr=0 net.ipv6.conf.all.autoconf=0 net.ipv6.conf.all.accept_ra=0

Hi, I'm running CentOS 7 on all my servers, in three different contexts : 1. simple local server 2. public facing server 3. router/gateway/firewall I'm currently in the process of moving my KISS-style network-scripts-style configurations to something more orthodox based on NetworkManager. Scenarios (1) and (2) caused no problems, but (3) is giving me some headache. Let me

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

Gnome's control-center now requires NetworkManager-wifi. But it's only a soft requirement, no shared libs involved. To keep your workstation NM-free, you want to install a dummy package that provides NetworkManager-wifi but actually contains nothing, ideally before updating to 7.5. Here's a script to create such a dummy: https://github.com/larsks/fakeprovide If you do this,

Hi, I'm currently reading the upstream "Considerations in adopting RHEL 8" document. The chapter about networking states that traditional networking scripts (shipped with the network-scripts package) are considered obsolete. I bluntly admit I don't see the point in this. As far as I'm concerned, I've been a happy user of NetworkManager since the early days (when

We ship servers to remote sites, which are rarely staffed with techs familiar with Linux. We have them tell us the static IP configuration for the box before we ship it, then we set it up for them here and ship it out to the site, where they just plug it in, turn it on, and walk away. That?s the ideal, anyway. What often happens in reality is either: 1. They give us incorrect static IP info,

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

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

Hi, I've created a bridge using 2 interfaces and have a lot of messages as follows: nov 12 15:30:22 localhost kernel: br0: received packet on enp0s3 with own address as source address nov 12 15:30:22 localhost kernel: br0: received packet on enp0s3 with own address as source address And the operating systems is extremely slow Interfaces files : [root at localhost ~]# cat

Have you tried to use NetworkManager ? After all ,anything network related should be done by it. [root at system ~]# nmcli connection add con-name dummy0 ifname dummy0 type dummy ?

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.
