similar to: Using eth0 on desktops with single network interface

Just installed centos 6.2. I run and ifconfig -a I see and em1 em2 and lo interface. If I go to /etc/sysconfig/network-scripts, I don't see an ifcfg-eth0. If I run ifup eth0 it comes back with "Device eth0 does not seem to be present, delaying initialization". Anybody have a clue? Thanks in advance.

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

Hey, I have KVM installed on my Fedora 17 box. I added the network interfaces of the virtual machines to the openvswitch bridge as follows: ____ ____ / VM1\______br0_______/ em1\ \____/ | \____/ | _|_ /VM2\ \____/ virbr0 is the virtual network switch VM1 and VM2 are on the same subnet having tap interfaces vnet0 and vnet1 respectively. em1 is the default

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

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup:

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

I'm just starting to test CentOS 6 in our environment, and as a first step did a basic install from DVD (Desktop target, all defaults). Next I will try to automate the installations as I did for CentOS 5 using the anakonda-ks.cfg file generated by the manual install. However, I can't wrap my brain around the new NetworkManager to get it to configure the eth0 interface to obtain an IP

hi everyone I'm having a bit of a puzzle on one centos system, I have four interfaces: nm-team1 10.5.6.100 em1 192.168.2.17 em2 192.168.2.18 p3p3 172.25.12.222 I do: ping 10.5.6.17 -I em1 PING 10.5.6.17 (10.5.6.17) from 192.168.2.17 em1: 56(84) bytes of data. 64 bytes from 10.5.6.17: icmp_seq=1 ttl=64 time=0.367 ms the same for -I em2, for -I em1 and naturally for -I nm-team1 - all good.

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

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

Okay you can stop laughing, yes I still have an NT server running for some special software. I've got a new linux machine running Samba version 3.6.23 and am having problems getting it to connect to winXP machines to talk to their shared printers It can join the domain and smbtree and smbclient sort of work. 192.168.4.28 is a windows XP machine NEW#: smbclient -L 192.168.4.28 -U

Hi all, Someone played with kickstart bonding with centos 6.4 ? CentOS 6.4, as upstream now support ifcae bonding in kickstart network section. I've an issue with configuring a second bonding iface in kicstart on CentOS 6.4. The first bonding (bond0) works as espected but the second is not configured during installation. I've a 6 nic server (two for "puclic" network, two for

Hello all, I'm wondering if there's any interest in trying to bond em1 and eth0 (respectively wired and wireless interfaces here), and if any, how to do it in CentOS6. I've found this, which could possibly help (but I'm failing yet): http://r.outlyer.net/linux:bonding https://help.ubuntu.com/community/UbuntuBonding Both are dealing w/ ifenslave. Any experience or point of

I'm trying to autoinstall a DELL 9030 desktop with CentOS7 using PXE and Kikstart. I fall in a strange problem (I have several other laptop or desktop using this install process without any problem, kernel and initrd are from a Centos 7.4 iso) - PXE boot start and the desktop load the kernel and the inirtd file - the kernel is booted and at this time the led of the network switch goes down

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*

CentOS 6.2......... Why do the physical interfaces report (correctly) that they're negotiated at 1000Mb/s, but when I `cat /proc/net/bonding/bond0` I get 100Mbps for the member interfaces, and when I ` mii-tool bond0` I get 10Mbps for the bond? ----------------------------------------------------------------------------------------- ethtool em1 Settings for em1: Supported ports: [

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 there. I have configured kvm domain (rhel6.4) with ethernet bridged over macvtap, and found no filtration applied except mac. 'virsh' just silently ignoring attributes 'filterref' and 'ip address' in different formats. No error on validate stage. Config examples: ... <interface type='direct'> <mac address='52:54:00:31:ae:1a'/>
