I was building a PBX machine using Asterisk and CentOS 4.0 (Trixbox 2.2). I have to use almost all the latest M/Bs those support Dual Core/Core2Duo. I just forgot the name of my current m/b but it is one of the new m/bs. My problem is i installed the OS successfully but after that, i found only lo is active. I can use netconfig but there is no eth0. I need to add the hardware. Since i tried to add eth0. but the computer is telling me that there is no /dev/eth0 found. Probably i have to install the ethernet card.(Means i want to use my onboard nic). Thus what should i do?? Best if i dont have to re compile the karnel since the Software is Asterisk embedded with CentOS, thus i need some kind of config file like rpms so i can install it. Is there any way?? Please help me...

Mishu~

Step one: provide useful information, which motherboard exactly??? which Ethernet device exactly???

Hint; the typed command 'lspci -v' will provide information about the on-board Ethernet device, example only the part about the Ethernet device;

06:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

Hint: after you figure out which Ethernet device you have on-board look at this sites Hardware Compatibility List;

http://www.linuxquestions.org/hcl/

well... i need to open the casing and then i can tell the exact model of the m/b. also i may get about it from the bios. Then i'll post again... will that help then?? i think so...

You can also use the lspci command to find out more about the NIC. I wouldn't be surprised if you had a REALTEK 8168, it's on quite a few recent motherboards and I remember that is was not recognized by Fedora Core 5 & 6 and CentOS 4. It is by Fedora 7 and CentOS 5. If it is the REALTEK NIC indeed, you should fetch the driver from REALTEK and install it yourself.

Well, i just loaded the software and did the lspci... then i got this....

02:00.0 Ethernet controller: Realtek Semiconductor Co. Ltd. RTL8111/8168B
PCI Express Gigabit Ethernet cotroller (rev01)

My bother board is: Intel D945GCNL and it has a on board NIC. I want to use that one... but i dont get any hw in the machine... i think it was not installed. so what should i do in order to use that onboard NIC??

I am trying to work with Asterisk + CentOS 4.5 = Trixbox 2.2.4

Now i need help... plz....

See: http://www.centos.org/modules/newbb/...10249&forum=40

Yep, two solutions:
- install the driver yourself
- install CentOS 5 instead, which does have support for that particular NIC

great... now i am trying to install the drivers... but well... i need to know how to install drivers and also i need to know very first that this installation (driver) will make life simple like if my machine restarts, things will not change and i will not need to install again after a restart/reboot... i'm checking...

Ya... trying to install... and opss...no way to install centos 5 right now.... i am using trixbox which is embedded with centos 4.5

downloaded the file... but they are damaged from the source... huh...!!! sourcing again... what to say?? :-(

If I remember correctly, the driver was first included with the 2.6.18 kernel. If you upgrade to 2.6.18-, the driver will need to be reinstalled manually. If you upgrade to 2.6.18+, it will come along with the rest of the update. So if you do updates, watch closely the number of any newer kernels about to be installed.

i want to use centos 4.5 and no way... now finally i have managed the driver. no i have to install... the readme of the driver tell that:...

<Requirements>

- kernel source tree (supported versions 2.4.x)
- compiler/binutils for kernel compilation



<Quick install with proper kernel settings>

Unpack the tarball :
tar vzxf r1000_vX.YZ.tgz

Change to the directory:
cd r1000_vX.YZ

If you are running the target kernel, then you should be
able to do :

make clean modules (as root or with sudo)
make install
depmod -a
==================

What it is mean?? so now how can i proceed?? i am a newbe and completely new on doing this....

well, how can i check if my lan has been installed after the first OS installation?? I have installed trixbox2.3-beta2 and then i didnt got the onboard nic. like previous... then lspci is giving same output. now at the very first, i need to know that the device has been installed. then i can go netconfig...

after doing ifconfig, i only got about lo (loopback) and nothing else...

plz help...

Mishu~~

Also i now have have the drivers downloaded... now i need a step by step guide for installing it. Karnel is 2.6....

You need to make sure that you have the latest driver available. There are a few versions around and the earlier ones all have a bug in my experience; they all involved editing the source files before they could be made to run.

Anyway, you need to make sure that you have kernel sources installed. On Redhat/Fedora/CentOS, this package is called kernel-devel. Once you have those installed, extract the driver source. Then cd into the driver folder and type in the commands as specified in the Readme. If all goes well, your NIC should now be detected. Go to System > Admin > Network for configuration of eth0; the dialog box should list the device in question. After that, you will need to restart networking (reboot).

Well, i will use centos...so where will i found the kernel devels??
