Ethernet card not getting detected.


Helloo everyone,

I am a newbie in linux.

I have installed fedora core 8 on my system. But i am unable to use LAN connection. here are the results of some of the commands which give error messages

Fedora 8 supported? Fedora is up to 14 now.

sacbravo,
i think your NIC is sit0, go to system-> administration -> network, enter the root password, and configure it. One more thing try ethtool -i sit0. I am a little bit confused about sit0 because I can't see physical address of it !!

sit 0

I think that sit0 is appearing bcoz, using the "neat" command ?I had chosen some random intel ether express driver(gigabit). But when i hit the activate button, It says "delay in initialization of eth0"

@NM04

In system> administartion> network, There is no hardware or driver currently, bcoz none of the default driver entries are compatible.
the result of service network restart is as follows:

[root@localhost ~]# service network restart
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
[root@localhost ~]#

I am not aware which is the ethernet controller, except that it is an intel gigabit device, which is evident from lspci command, in my first thread.

i think you need to install the driver for your ethernet controller. I guess when you installed the fedora 8 you didn't checked the module for your ethernet controller. you can do one thing, do you have an extra NIC, if yes, attach it to the motherboard and then boot. Also tell me your motherboard name and the number written on the bar code strip.

Actually i am using a PXI based system from M/s NI: http://sine.ni.com/nips/cds/view/p/lang/en/nid/206809. I did not get any option for ethernet controller during installation. I suspect it is because fedora 8 setup doesnt have the particular modules for this gigabit ethernet controller.

Meanwhile i had installed F8 on another cPCI based system, where i got the option for ethernet controller during installation. It is working fine there. I tried re-installing F8 on the PXI system, but yet again i did not get any option for the ethernet controller configuration.

So kindly tell me is there any command which gives us information about the ethernet controller in the system (even BIOS command). The info isnt available in any of the datasheets. Meanwhile i am trying to get the info from NI support.

1) try, service NetworkManager restart
2) try, service network restart
3) try one more command "ifconfig -a" or "lspci |grep -i ethernet
