I hope thats two seperate files, ifcfg-enp0s8 and ifcfg-lo ... otherwise, why is a bridged physical interface configured

If the purpose of this is to demonstrate VMs you just want to bridge the physical interface so that the guest can

hello all, I have been trying to set-up bridged network with VLAN and not able to succeed as many tutorials address only single NIC. I am trying to setup 2 guests (backtrack instance) each guest has NIC1 and NIC2. following is snippet for guest1 I am not able to get 192.168.0.2 address back on guest eth0. VIRT-MANAGER GUI : guest1-lan details radio button left side panel NIC1

took a couple months off due to road blocks, hoping a fresh look would allow me to use my server as desired. I have three ports, eth0-2 over two nics. I want to bond them, and then use a bridge to connect to virtual machines on the virtual host computer. Never having done this, I am confused on some parts. Here is where I am at now and any pointers helpful. Single server, centos 6.x My issue

Hi, I'd want to configure persistent static routes, ie in config files, but I can't configure static routes, I tested: [root at centos7 ~]# cat /etc/sysconfig/network-scripts/routes-enp0s3 ADDRESS0=10.10.10.0 NETMASK0=255.255.255.0 GATEWAY0=192.168.1.1 logs says nothing: ago 27 15:38:29 centos7.vhgroup.corp NetworkManager[2299]: <info> Activation (enp0s3) Stage 5 of 5 (IPv4

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

CentOS-5.5 # uname -a Linux inet05.hamilton.harte-lyne.ca 2.6.18-194.32.1.el5 #1 SMP Wed Jan 5 17:52:25 EST 2011 x86_64 x86_64 x86_64 GNU/Linux Can anyone tell me why I am seeing these error message? Specifically, why is TYPE=Bridge giving Unknown connection type 'Bridge'? Jan 13 08:25:31 inet05 nm-system-settings: Loaded plugin ifcfg-rh: (c) 2007 - 2008 Red Hat, Inc. To report bugs

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 All, I have 2 NICS in this system. CentOS 6.4 eth0 is the virtual IP from PFSense mapping connected to the router, works fine. eth1 is a second NIC that I have assigned a private IP to and connected it to a switch on the private network. I have many other private devices, so I know this setup works. When I connect the cable to the switch and bring up eth1 the system basically stops taking

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

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
