Hello, is this only my mistake,or can help any from the list? I have 3 host computer on different places, but all have the Problem when starting a client "KVM" to connect to the bridge from the host. It is near not possible to start a client, only after 10-20 reboot/restart from the client's the network is starting correct? Is this only on my computers or have other also this

Hi, Just to clarify (you didn?t mention it) - do you have ?NM_CONTROLLED=no? line in NICs ifcfg scripts? Sent from my iPhone > On 11 Dec 2018, at 16:22, G?nther J.

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.

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. Here is my ifcfg-eth0: DEVICE="eth0" NM_CONTROLLED="no" ONBOOT=no HWADDR=xx:xx:xx:xx:xx:xx TYPE=Ethernet BOOTPROTO=none IPADDR=192.168.2.5 PREFIX=24 GATEWAY=192.168.2.1 DNS1=192.168.2.1 DNS2=192.168.2.1

Is anyone frustrated by Network Manager? I wish CentOS just used the basic configuration files like the ones on BSD-style OSes. Those are so simple in comparison. Each time I reboot, it seems like the configuration file I create for Network Manager gets destroyed and replaced with a default file. Nothing in the default file would actually make sense on my network, so I'm not even really sure

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 CentOS gurus, and a belated Happy New Year (or an early Happy Chinese New Year). I'm in the process of building a CentOS-6 KVM host machine whose only function will be to run four independent 'm0n0wall' firewall guest instances. I have a couple of quad-port Intel NICs to provide four WAN-side and four LAN-side ports, which will not be shared with any other guests. Remote

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

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,

I have need to use the old network-scripts and not NetworkManager. I did yum install network-scripts, I have ifcfg-eth0 set for ONBOOT=yes but it is not starting on boot. What have I missed ? Jerry

I've been banging my head against the wall trying to get a simple two NIC bond to work. Got really odd behavior from service network restart, then finally decided to disable NetworkManager. Voila! Bonding and the network service script starts working just the way I expect. Does anyone here actually use NetworkManager on anything but a laptop or desktop? I can't seem to figure out a reason

Hello, I want my CentOS 6.5 computer to have a static IP. Currently I get the IP I want because I have my router assign it on the basis of mac address. I placed the following file as: /etc/sysconfig/networking-scripts/eth0 DEVICE="eth0" BOOTPROTO=static HWADDR=00:1F:D0:9E:AE:67 ONBOOT=yes TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes NETMASK=255.255.255.0 IPADDR=192.168.0.99
