similar to: No network on cloned CentOS 7 installation

Hi, A couple months ago, I migrated our local school (two servers, 20 desktop clients) from Slackware 14.1 to CentOS 7. The desktop clients are running a customized lightweight desktop based on Xfce: https://blog.microlinux.fr/poste-de-travail-xfce-centos-7/ Home directories are all on the server, and authentication is centralized. Everything works fine so far. With Slackware I had found a

Hi, I'm currently setting up a local FTP server, to receive disk images sent with G4L (Ghost4Linux). This server has been running Slackware Linux before, and the Vsftpd setup was relatively simple. With CentOS things seem to be slightly different, so I'm currently trying to work things out. For the moment, two things seem to be creating problems, the simple iptables firewall and

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 All, I guess it is very common for administrative purpose, to dump and restore a CentOS 7 system. I usually use dump/restore commands. However, I?m having trouble to handle installing bootloader and creating initramfs for C7 system. Does anyone know a good document source that details those procedure? Thank you, Xinhuan Zheng

Hi, When I initially boot my system, it fails to bring up the network. Once booted, if I run "systemctl restart network.service", or even stop, wait a while, then start, it starts up fine and all is well. I'm running Fedora 19 (updated). I followed the instructions on this page to set up a bridged network: http://wiki.libvirt.org/page/Networking I note however that I did *not*

dear All, I'm facing this routing problem, the setup is actualy part of ltsp, but I think this problem is Centos-specific. The server is a Dell Poweredge R210. The install is standard 6.4, updated. I have one nic facing the public internet: vi /etc/sysconfig/network-scripts/ifcfg-em1 DEVICE=em1 BOOTPROTO=none HWADDR=d4:ae:52:c1:28:2b NM_CONTROLLED=no ONBOOT=yes TYPE=Ethernet

Hi, In my daily work I'm mainly using USB keys for work : one with CentOS 7, one with OpenSUSE Leap 15.1, one with Slax Live for data recovery purposes, one with Ghost4Linux and one with FreeDOS which I use for flashing the odd BIOS. Last week I bought a set of three flashy colored USB keys in a local shop. To my surprise, none of them seem to be able to boot anything. When I write a

Hi Clint, systemd-networkd doesn't use those files at all.

We just got DELL R920 and installed Centos 6.5 on it.? After installation, network not function.? We manually enter IP address, gateway and netmark on "em1".? we also do following: 1. startup NetworkManager 2. /etc/sysconfig/network-scripts/ifcfg-em1? ==> NM_CONTROOLED=yes I tried to startup network and get error message: Bring up interface em1: connection activation failed

Hello everyone I am running into some strange issues when configuring networking interfaces on my physical server running Centos 7.5. Let me give you an overview of what's going on: We have a physical server, running CentOS 7.5. This server has one 4 port NIC and one 2 port NIC and a Dell IDRAC port. The first port of the 4 port NIC, em1, is used for Management traffic. The first port of

Hi, Our desktop clients are running CentOS 7 with the Xfce desktop from EPEL. The CR repository is enabled. A few days ago I launched an update, which brought in close to 1 GB of packages. I had some weird problems on two clients. One is an old Dell Optiplex 330 with a legacy video card.

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,

Hi, I have a CentOS 7 desktop client installed on an old Dell Optiplex computer with an Intel video card integrated into the motherboard. The card has a single VGA connector, and the 19" monitor is connected to it. I wonder how I could connect a video projector to this computer while keeping the monitor, in a mirroring configuration, e. g. output is the same on the video projector and the

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

My manager tells me a system in the datacenter is down. I go down there, and plug in a monitor-on-a-stick and keyboard. It's up, but no network. I try systemctl restart NetworkManager several times, and ip a shows *no* change. Finally, I do an ifdown, followed by an ifup, and everything's wonderful. My manager thinks that the NM daemon thinks everything's fine, and there've been

Hello All, I seem to have run into a bug with the new --bridgeslaves=<INTERFACE> option. It would seem that if I tell the bridge device to use a virtual interface (like bond0) rather than a physical interface (em1/em2) that kickstart completely barfs on it. I have provided my network section below which works fine as long as i don't enable all the bridge content. When the
