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 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

centos 5 had modprobe.conf entries for eth0 and if present eth1. something like: alias eth0 forcedeth alias eth1 e1000e For the new centos 6 (I have the rhel 6 client installed on my laptop) the modprobe.conf file is gone. Which is fine. I understand files can be created in /etc/modprobe.d and server the same purpose. My question is I dont see (doing a grep) any eth0 alias's in the files in

What is happening in centos 5 with network config files??? I have a machine with 2 network cards. ifcfg-eth1 keeps changing to DHCP. All my static setup is gone. Why is it doing this? How can I stop it? I run "netconfig -d eth1" and re-setup my static information. I reboot and now I am back to DHCP. I have a gigabyte motherboard, nvidia chipset. forcedeth driver. eth0 is e1000.

All, I've got a machine running CentOS 5.3 and this machine has got 2 - built-in 1 Gig NICs and a expansion card with 4 - 100 Meg NICs. For whatever reason at install time, it made the expansion card eth0 through eth3 and the internal ports eth4 and eth5. And by default the 'machine' is known on the network by the eth0 NIC, so my throughput is limited to 100 Mb. How can I force

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

I have a strange problem on one machine where eth0 gets killed when I add a virtual interface. It's got something to do with the NIC ordering or with the xen network script having a problem with multiple NICs and virtual interfaces. I could need some help/comments on this. Some history: I added a NIC (chip identifies as Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit

I have a number of machines that have 4 NICs, two of which are actually in use, running Centos 5. When they are rebooted, they seem to change the eth interface names, assigning them in different orders. I'm a little fuzzy on the details because they are at a remote location and I can't access them easily - especially after the network breaks. Shouldn't: alias eth0 bnx2 alias

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.

Hi, I''m a newbie to Xen and I need some help. I saw user ''datto'' had a similar problem but changed to FC4 to resolve it. I''m currently running FC3 and Xen2.0.7. I did the usual ''make install'' and I can boot into Xen dom0. However, my network card is not working. The driver is found in the linux-2.6.11.12-xen0 tree but not selected. I

Hi All, Long time no chat ;-) Asterisk 1.0.9 (sometimes) won't authenticate IAX phones after re-boot of SuSE 9.3 box I've traced the problem to be with the firewall and the fact that I have 2 NICs in the box. Now that I have opened port 4569 on both interfaces, asterisk seems happy *but* does anyone know how to force SuSE 9.3 to always bring up a specific NIC before the otherone? On

Hi, I have a LAN server running CentOS 5.11 with two NICs eth0 and eth1. I'd like to swap the interface names, but I don't know how to go about that under CentOS. Here's what I would do on a Slackware server (I have one next to me in my office). Open /etc/udev/rules.d/70-persistent-net.rules and edit it: # PCI device 0x8086:/sys/devices/pci0000:00/0000:00:04.0/0000:03:00.0 (e1000e)

I have a bunch of HP BL465c G5 blades, with additional dual-port network adapters. The onboard interfaces use the bnx2 driver, while the expansion card uses tg3. All 4 interfaces are detected by both Anaconda and the installed system, but Anaconda is reversing the ordering: Anaconda: eth0 Card 2, Port 1 eth1 Card 2, Port 2 eth2 Card 1, Port 1 eth3 Card 1, Port 2 BIOS and Installed Kernel:

Hi all, I have been having an issue for over a year with several Xen installations and have not been able to find out if this is just something I am missing. Basically I am trying to configure a firewall with two ethernet cards in a domU using pci passthrough. I am hiding the Ethernet cards at boot time via the pciback.hide kernel option. Right now I am running Xen 3.3.0 and the two Ethernet

Hi folks, Host - Debian Etch Guests - Debian Etch. Performed following steps to create duplicate guest, a mail server. 1) # cp /etc/xen/guest-1.cfg /etc/xen/guest-2.cfg edit guest-2.cfg changing the settings of:- disk = [''file:/vserver/domains/guest-2_directory/disk.img,hda1,w'', ''file:/vserver/domains/guest-2_directory/swap.img,hda2,w''] # Hostname name

Actually, here is what shows up in the log, regardless of whether the driver is built-in or loaded as a module: Feb 5 10:16:15 sparenode1 sysctl: net.ipv4.conf.default.rp_filter = 1 Feb 5 10:16:15 sparenode1 sysctl: net.ipv4.conf.default.accept_source_route = 0 Feb 5 10:16:15 sparenode1 sysctl: kernel.sysrq = 0 Feb 5 10:16:15 sparenode1 sysctl: kernel.core_uses_pid = 1 Feb 5 10:16:15 sparenode1

Just installed from scratch 5.5 Weird, eth0 is now eth1 and eth1 is eth0. Don't even know how I'm sending this message as the the CentOS machine can't connect to the internet and this windoze box uses the Centos box as a gateway.

Hi all, I have a CentOS 5.4 server-only installation, i.e. no X installed, and for some odd reason /etc/resolve.conf gets overwritten by NetworkManager on a constant basis. I haven't been able to track down how often, but I think it's on the hour, or something. This is the conents of the file right now: # Generated by NetworkManager # No nameservers found; try putting DNS servers into

Hello all, I'm having unusual difficulty configuring teaming with Centos 4.2. The 2 NIC's are Broadcom. The HW is HP DL360 and there is no teaming driver for RHEL4 since it comes with package (says HP). Since there is no teaming driver from centos (as far as I know), I tried the Broadcom Driver, configured the team file, but the team just wont come up. A Virtual Interface should be up
