similar to: Nic order detection

I have two servers with identical hardware ... TYAN i3210w system boards with dual intel gigabit interfaces, and a PCI intel gigabit nic. I'm running Centos 5.4, x86_64, 2.6.18-164.6.1.el5 Every other time I reboot, the nics initialize in a different order. anaconda had setup /etc/modprobe.conf with alias lines for the cards: alias eth0 e1000 alias eth1 e1000e alias eth2 e1000e However,

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 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

Hi, In a corporate environment we are not allowed to use DHCP/PXE for doing network installations. This means we have to look for other solutions. Our solution is to use an ISO image (mounted via a KVM solution) to kick off the network installation. A big problem currently is that the order of the network interfaces is arbitrary (depends on the order of the drivers loaded) and is not

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.

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, I've been using CentOS & Xen on a server that has 2 VM's configured. The default configuration includes one physical iface that is propagated (by a default bridge) to the VM's. Since I wanted to configure additional physical iface, define a new bridge and propagate it to the viface-s of the VM's, i configured the bridge/phys. iface and brought it up (here are

Hello, I have a big problem with my servers. I have 4 NIC on all my KVM Servers but the most time on a start (restart) I lost one NIC? It is not always the same, but this two are virtio NICs. with ifup eth0(1) the system say,I have no configured eth0 or eth1 file ? Can any tell me what I can do? thank's for a answer NetworkManager is disabled. -- mit freundlichen Gr??en / best regards,

Hi, I have a dell poweredge 850 with centos 4, freshly installed. I'm now trying to add in a fibre -> sata raid enclosure with LSI HBA's in the 850. My problem is the enclosure gets detected first, hijacking sda and sdb from the internal SATA drive and causing kernel panic at boot time. I've tried changing the order in modprobe to the following: alias eth0 tg3 alias eth1

I was given the challenge recently of creating a LAN-LAN bridge between two buildings several hundred metres from each other, using only existing Cat 3 wiring and without having to resort to an expensive and finicky 5 Ghz wireless link. I was able to create a 90 megabit link for about $3,000 Cdn with new PC's, CentOS 4.1, and the newly avaliable Black Box VDSL Ethernet Extender, which

Hi, I've installed CentOS 5 on a Dell pe1950 with 2 dual port NICS. One of the NIC is an Intel and use the e1000 module. The problem is when the server is rebooted it does no asign the ethx name to the NICs, instead the so assign something like _dev377362... so i dont have networking on the server. Any ideas what is happening and how to solve it? Thanks. -------------- next part

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 All :) I have three servers, all with centos 7 installed 3 days ago. I need on them "old" naming scheme (ethX) for network interfaces, because of that: # grep GRUB_CMDLINE_LINUX /etc/sysconfig/grub GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_node-XY/swap rd.lvm.lv=centos_node-XY/root rhgb quiet ipv6.disable=1 net.ifnames=0" net.ifnames=0 was added and afterwards I ran:

Getting "bnx2i: iSCSI not supported, dev=eth0" for all the NIC adapters on all of my R710's running CentOS 5.5. Here is an sample of the error messages: bonding: Warning: either miimon or arp_interval and arp_ip_target module parameters must be specified, otherwise bonding will not detect link failures! see bonding.txt for details. bonding: bond0: setting mode to active-backup

Hi, I'm wondering about the impact of using both dom0 and domU's on a server at the same time. I'm worried about the performance impact of running a Mysql server in a domU and now I'm thinking about moving the Mysql part of a LAMP setup into dom0 and running a few Apache guests as domUs. Since the Apaches will serve mostly from an NFS share they won't have much impact on

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.

Hi On a multihomed box how can i set different gateways for each NIC? Setting them in the ifcfg-ethx does not seem to make any difference to the routing? thanks

Hello, I have been using Xen on a Debian Lenny server for quite some time. I decided to build a new Dom0 using identical hardware, but newest version of Xen from repositories with Debian Squeeze. I attempting to create a new DomU on the new host which is similar to an existing DomU running on the older Lenny host. The DomU is a three NIC firewall. Two of the NICs are virtualized. One NIC is a

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:
