similar to: How to autoconfigure network?

Hi, Has anyone tried upgrading xen domu's from 5.2 to 5.3? I just did a yum upgrade glibc & yum upgrade yum. All appeared to go well but when I rebooted and tried to connect to the network, I could not. Looking at /etc/sysconfig/network-scripts I see that the that there is now an ifcfg-eth0 and an ifcfg-eth0.bak. ifcfg-eth0 now contains configuration for a dynamically configured

Hello CentOS list, On all of my CentOS 5 VMWare ESX3 virtual machines (about 15), after installing a new kernel and rebooting the machine, the Network script tries to run dhclient and can't determine the IP info (since I don't run a dhcpd server... it's a static IP only lan). This also backs up my ifcfg-eth0 file to ifcfg-eth0.bak and writes a new ifcfg-eth0 that has dhcpd with

I've spent some hours on this without success - any help greatly appreciated. I've just done a new RHEL6 setup, with a KVM guest (first time). The basic installation works fine until I start libvirtd; at this point, the host machine loses access to the external network: step 1: ping from host to network works; external machine on network can ping both eth0 and br1 on the host step

I'm having a puzzling problem with system-config-network-cmd in CentOS 6.4. I have a workstation with a number of different grub boot configurations (a spare for a set of workstations, basically), each of which has a parameter MYHOST=<hostname>, and I am using system-config-network-cmd to set the boot configuration during the network process (using a small custom system service that runs

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

I am attempting to put 3 network cards in one box, running centos 64 5.4 network cards are forcedeth (motherboard), e1000e and r8169. I have ifcfg-eth0, ifcfg-eth1 and ifcfg-eth2 all configured up. All looks fine. eth0 is my internal network (forcedeth) eth1 is Cable modem eth2 is T1 data Once I connect the three networks and try to ping something all I can ping is internal network machines.

I have centos 64 6.5 I installed bridge-utils I installed tunctl I added BRIDGE=br0 to ifcfg-eth0 I created ifcfg-br0 with correct settings I did service network restart and I get an error about br0 not present. When I plug in the second network (USB to ethernet) It detects as eth1 What do I need to change to get this to work. Thanks, jerry

Hi all, I used to manage network through /etc/sysconfig/network-scripts/ifcfg-* Most of my use case are vlans (ie: eth0.1) an aliases (ie: eth1:3) My context in headless VMs (no DE, no Xorg, no GUI) With CentOS7 and systemd: is it still managed with /etc/sysconfig/network-scripts/ifcfg-* ? For the mount component, I found that systemd kind of "sources" /etc/fstab and converts it to

Hello /etc/sysconfig/network-scripts/ifcfg-eth0 looks like this: # Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) TYPE=Ethernet NAME=eth0 NM_CONTROLLED=no IPV4_FAILURE_FATAL=yes UUID=cc2635ff-3c14-48ba-b19a-84c5b9d36a9d ONBOOT=yes DEVICE=eth0 BOOTPROTO=none HWADDR=00:50:56:01:00:01 BROADCAST=192.168.0.255 IPADDR=192.168.0.10 NETMASK=255.255.255.0 NETWORK=192.168.0.0

My local Dom(0) network stops working as soon as network-bridge is started. I''m running centos 5.3 and installed xen from repository via yum. I have a LinkSys 10/100/1000 PCI card in my machine. Driving me crazy! Any ideas? I''ve stumbled upon a couple possibles regarding using ethtool which seems to then render my bridge unusable. Any help appreciated for someone

Hi all, Having a 4 NIC server, I want to bridge eth2 and eth3, with a bridge named br0. Searching the web I only found about creating a file /etc/sysconfig/network-scripts/ifcfg-br0, but did not find where to explicitely list what ports will be bridged. Where is it configured? Thank you. -- RMA.

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.

I'm having trouble with the bridged network setup. I'm new to kvm, but I got a window xp sp2 guest set up without trouble a few days ago. I followed the instructions in the RH virtualization guide, and all was fine until I had to reboot the host machine a few days later. Then, I lost networking altogether on the host machine. I lost track of all the things I tried, but finally got

Anyone know off the top of their head the "right" way to hard set a link automatically to 100Mbps Full Duplex, etc using the ifup or ifcfg files? Don't see options in the scripts that might cover this, but maybe there's a more elegant way to do it than to do something in rc.local or hack up the ifup files myself... Ray

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A few months back, I tried to use the network scripts to provision an IPv6 range like can be done with IPv4. I was using CentOS 5.2 at the time and was informed that 5.2 was broken in this regard. I have upgraded to CentOS 5.3 now and I am trying to get IPv6 to provision an entire range of IPs, but I am still getting the old behavior and no IPs are
