I want to install CentOS from netinstall CD, but it doesn't work for wireless connection, because it just looks up for eth0 connection. Well, I connected server to wired USB connection and it's named eth1. I want to use netinstall CD but using eth1 connection. Is there any way for doing it?

I am trying to install 5.3 using net install disc, where it hangs for over 30 minutes trying to retrieve stage2.img. Second time. After first time and waiting over 25 minutes, I tried Debian net install on another box, and it's done with installation long ago, while this one is still hanging (and from the looks of it I doubt it will continue).
1. Network is good, the box pings, network parameters are good, Debian worked flawlessly with same parameters
2. It did pull all it needed before stage2.img
3. Plenty of RAM in the box, over 3 GB
4. The box needs no additional drivers (except newer version of kernel as vanilla still doesn't have a complete support for Intel DP43TF board), distro has them all
i have installed centos 5.1 but it won't recognize 2nd nic card (eth1). i was unable to install the driver supplied by the cd. i am using intellinet gigabite pci network card. the network card recognize by centos 5.3 but i need to use centos 5.1. i also tried another intel gigabite adopter but it also won't recognize by centos 5.1.

I'm having a problem and despite I have googled a lot cant find the root cause. I have a server with two embedded NICs and centos 5.5 loaded. I need to have one NIC with a fix internal IP address to communicate with the intranet and a second NIC with a fix address from my telephone provider. I know I cant have two different gateways on the net so I configured only the gateway for the second NIC leaving the field empty for the first.
I found that the first NIC is handling all the traffic for both interfaces (eth0 and eth1) and the second NIC is in standby (or doing nothing). This is causing the traffic intended for the second NIC never reach their destination. After a couple days working with the BIOS and other configuration files I tried another way of solve the issue. I put a fix address for the first NIC and another fix address for the second NIC (both in the same subnet) and from a computer pinged successfully both addresses. However if I disconnect the cable for the first NIC both interfaces goes down (eth0 and eth1) and both pings fails. If I disconnect the cable for the second NIC (with the first one connected) both pings still running without any disturbance.
I worked also in a second server with different hardware (different kind of motherboard, different NIC manufacturer, etc.) but the problem is also present in this second server. I was reading about NIC bonding or teaming, but this configuration is not present in the modprobe.conf or in the ifcfg-eth0 files, so I believe the problem is not related with this feature. Do you know what is happening with the NICs and how can I get two really, fully independent NICs?
I have 2 network interface on 1 server and i got a problem finding a solution for it.I have 1 java application and i want it to use the eth1 for that application and not the default eth0. On eth0 i got for example xx.xxx.xx.22 and on eth1 i got xx.xxx.xx.23 and i want the java app to use the 23 ip one.

I am trying to attach my server to 2 diferent networks, with fixed ip addresses,
eth0 = 192.168.0.2 255.255.255.0 with gateway 192.168.0.1. This is currently working, and I can ssh o the machine on this address
eth1 = 192.168.150.5 255.255.255.0 with gateway 192.168.150.1
When I try and start eth1 with ifconfig eth1 up, I get the error message "eth1: unknown interface: no such device"
I have configured eth1 using system-config-network-tui and /etc/sysconfig/networking/devices/ifcfg-eth1 looks correct

Problem: Can't get bridging to work properly.
I'll start by saying that most of this is built inside of a 64bit ESXi 4.1.0 server. Should be obvious by the picture below.
Trying to set up a bridged CentOS box. Ultimate goal is to set up a Transparent Firewall. The machine labeled 'Desktop' is a Windows XP running DHCP. It gets assigned an Internet routeble IP address. At this point, nothing is running a firewall.
Symptoms:
Gateway can ping CentOS bridge
CentOS bridge can ping gateway
CentOS bridge can resolve DNS names and ping FQDNs on the Internet.
CentOS bridge CAN NOT ping Desktop

I have openvpn tunnel setup between two CentOS servers. One of the CentOS servers also acts as a DHCP server for some client computers.
Server A= OpenVPN server
Server B= OpenVPN client (connects to Server A with OpenVPN)
The two CentOS servers can ping each other (172.16.0.0/24) via the tun0.
However, client computer connected to Server B (DHCP server) can't reach 172.16.0.1 (which is the OpenVPN server).
I think I am missing some routing in my "ip route show". Following is the full picture:
What command can I issue to get this fixed? something along ip route add?
There is no firewall service on both end. service iptables stop! I can't bridge eth1 and tun0 as DHCP server might mess up the other side. I can't do a push of "redirect-gateway def1" because then clients loose their IP as they send DHCP requests to Server A.
What is the difference between the boot.iso and netinstall.iso images? I've looked at the wiki and done some Googling, but haven't found a good answer yet. I know it is probably going to be something obvious, but in the context of installing a Xen fully virtualised guest there doesn't seem to be much difference. After booting both ask for the location of the install tree and proceed happily.

I'm running CentOS 5.2 on an ASUS M2NPV-VM motherboard. This motherboard includes an NVIDIA nForce 430 built-in Gigabit MAC (network interface). I've also installed a second PCI network interface card (NC100 Network Everywhere Fast Ethernet 10/100). The PCI-based card was configured as eth0, while the built-in NIC was configured as eth1. The machine is used as my firewall/router, so eth0 is my internal interface, while eth1 is my external interface. I've had some intermittent problems with the built-in (eth1) NIC. When booting the machine and it attempts to bring up the interface, I get the following message: forcedeth device eth1 does not seem to be present, delaying initialization From that time forward, there is no eth1, and so no external network, etc. If I try running /etc/sysconfig/network-scripts/ifup eth1 (from that directory), it results in the same error.
Originally, I was getting this error when installing the operating system on the machine. At that time, I was using a 75' ethernet cable (as I was working on the machine in my office, and the external ethernet jack was in another part of the house). As soon as I moved the machine to its permanent location (which is within 2 feet of the ethernet jack), the problem went away. However, I just updated the kernel (via yum) from 2.6.18-92.1.22.el5 to 2.6.18-128.1.6.el5, and now it fails 9 out of 10 times. I'm not even sure what I can do to debug this. I'm assuming there is some kind of timing problem with the initialization. Is there a configuration parameter I can set to allow more time for the initialization to do what it needs to do, to prevent this error?
this should be trivial for all you big sysadmin guys My box is a firewall/gateway. ETH0 is on the Internet-side, and is fully auto-configured (DHCP client) from my ISP. ETH1 is on the LAN-side, has DHCPD enabled, and I route the traffic to/from the Internet via iptables (NATting, of course). Everything works pretty good, except for the DNS-server assignment via DHCP: how can I configure dhcpd.conf to assign the SAME dns-server I receive from my provider on ETH0 to all my PC on ETH1?

1. Do I need a Centos RAID device driver for hardware RAID-1 on the HP DL380R05 E5420 Server?
2. Should I use Centos i386 or Centos x86_64 in this case? Which one: CentOS 5.2 or CentOS 5.3?
3. Does Centos support Embedded NC373i Multifunction Gigabit network cards?

I am having new hardware and IDE driver for that hardware as drive disk image (it8213_centos53.img). CentOS 5.3 installation is working fine with drive disk image at USB and CentOS 5.3 at DVD. Our application uses CentOS 5.3 and we build a custom kick-start ISO for installations. Using that ISO client is going to install on all hardware boxes.
Note while installing :
a) No network connection is avalible.
b) No USB isavalible.
c) No floppy is avalible.
d) Only single CD-ROM is avalible.
So, is it possible to build single custom kick-start CentOS 5.3 ISO which contains dirve disk image and entire installation will be done using that image. If so please let me know the steps to build it.
