I''ve been using Puppet now for a month or so and I''ve come to a problem that may warrant an additional Puppet metaparameter. I''m advocating the addition of a metaparameter called "preaction" (or something like that), which will perform some arbitrary action before the resource is modified. There may be a way to do this within Puppet already (with some

I have a server located remotely running CentOS 5.x. I need to have two IP's on the same interface. So I have this: /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none BROADCAST=69.x.x.199 HWADDR=00:x:x:x:c6:10 IPADDR=69.x.x.194 NETMASK=255.255.255.248 NETWORK=69.x.x.192 ONBOOT=yes GATEWAY=69.x.x.193 TYPE=Ethernet So I added this:

I have CentOS 4 running on an old (early model) p3 with 64 MB RAM. It is acting as a router and firewall for my LAN. CentOS is doing a really good job with Shorewall + DHCPd - on a 10 Mbps cable modem, I see ~ 9.7 Mbps of throughput even when numerous tcp streams to different LAN hosts are running. I would like to add a virtual interface to one of my LAN interfaces. My LAN interface

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.

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

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

I need to allocate public IP address to two guest os. I have only 2 network card Interface on server. say eth0 and eth1. I set eth1 a public IP address. so it should in # vi /etc/sysconfig/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=static HWADDR=00:1a:4d:83:ad:00 BROADCAST=202.127.29.0 IPADDR=202.127.29.5 NETMASK=255.255.255.0 NETWORK=202.127.29.0 ONBOOT=yes TYPE=Ethernet Question 1: do I have to

Setting up bonding in active-backup mode 1 (using ARP monitoring) on a server, it looked OK, but pulling the active link cable didn't actually work, it didn't fail over. Eventually with manual playing around with modprobe, ifconfig, ifenslave, etc., a solution was stumbled upon: enslave the eth1 device before eth0, and all is good. Why this should matter is a puzzle - I could not find

I have a server with 4 nics. Two are using different internet connections, both with static IP's, and two are connected to our private network. The two internet facing nics seem to be battling over the gateway designation. Which ever I designate as the gateway the other stops responding to incoming traffic. I need both to listen to inbound traffic. One for our main web page and the other

Hi, I'm trying to configure a network bridge over a bonding without any success. Here is my configuration: ifcfg-eth0: DEVICE=eth0 HWADDR=00:1E:C9:E8:3F:E5 ONBOOT=yes USERCTL=no MASTER=bond0 SLAVE=yes ifcfg-eth1: DEVICE=eth1 HWADDR=00:1E:C9:E8:3F:E7 ONBOOT=yes USERCTL=no MASTER=bond0 SLAVE=yes ifcfg-bond0: DEVICE=bond0 ONBOOT=yes BRIDGE=br0 USERCTL=no ifcfg-bridge0: DEVICE=br0

I'm running into a situation where a bogus bonded interface named "bond0" is being created, in addition to the desired "bond2" interface. Can anyone confirm this? Anyone know why it's happening or what I do to get rid of it? I wanted to start my numbering scheme at 2 instead of 0, which I didn't think would be a problem. As you can see, I have no reference

Hi all, I just noticed that my two nics that are bonded via mode 0 are showing the same mac addy in ifconfig. Is this normal? In syslog I keep getting; kernel: pbond0: received packet with own address as source address Some guidance is appreciated before I dive in and troubleshoot. If I don't list the mac addy in my ifcfg-th# files, only one of the 2 nic comes up during boot.

Some of the Red Hat Enterprise Linux servers in our environment sometimes get assigned virtual IP addresses (eth0:1, eth0:2, etc). Puppet Dashboard''s parameters seem like an ideal way to define and provision virtual IPs on these servers. One could create a "vip1" parameter on a node, and define a value of the IP address to use for that vip. A manifest could then be written to

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

Hello, I'm trying to set up IP aliases within a QEMU/KVM guest on CentOS 5.5 x86_64, going through a bridged virtualized interface. The virtualized interface in the guest is configured as follow: # ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none PEERDNS=yes GATEWAY=IP.OF.HOST.GATEWAY HWADDR=11:11:11:11:11:11 IPADDR=IP.OF.GUEST.ETH1 NETMASK=255.255.255.255 ONBOOT=yes ARP=yes USERCTL=no IPV6INIT=no #

Hi all, I've setup a ethernet bond on my centos 5.6 server , when i do a reboot the bond does come up but cleared all the slaves and i've to manually re-add them with ifenslave. does anyone know a solution to this? am i missing something? offcourse i can add it to my rc.local but there must be a more elegant way. please see my configs below Thanks, Wessel ifcfg-bond0: DEVICE=bond0

Hello: I am trying to follow the RHEL virtualization guide to set up a bridge on a system running CentOS 5.4. I copied my ifcfg-eth0 to ifcfg-eth0:1 and set its content to this: DEVICE=eth0:1 HWADDR=[The MAC address from eth0] ONBOOT=yes BRIDGE=br1 I then created ifcfg-br1 with this content: DEVICE=br1 TYPE=Bridge BOOTPROTO=static BROADCAST=192.168.2.255 IPADDR=192.168.2.202
