webpage could not be found

Whats going on out there in linux land. I work with unix so i understand but for the life of me i can not get the internet to work on linux 9. It appears linux is not detecting my wireless card or my ethernet card. I am connected by a dsl connection. I have a dual boot system using win xp and red hat 9. When I use win xp everything works so I know its not a hardware problem. I dont know what i need to do. Set it to a lan or reinstall drivers or what. I am lost and could use a hand.

look for clues in dmesg

#dmesg |grep eth

/etc/sysconfig/hwconf

too will give you a list of devices detected by Linux.

ok when booting up etho says failed.
when i do ifconfig i get an ip address and a mask it says up loopback running. when i do /etc/sysconfig/hwconf as root it says perm denied. when i do a /sbin/lspci it has a listing for the broadcom ethernet card i have it reads like 2:01.0 ethernet card and so on. my kernel is 2.4 20-8.
every time i try to get on the internet using red hat 9 it says webpage could not be found. unknown host. I just want to get on the net. i used mozilla, konqueror nothing works. in windows you would probaly hit detect network settings what would be the equalivent in linux red hat 9. I dont have any ideas. any help would be appreciated.

It appears that only your loopback adapter lo is up. So either your network card is not detected OR the appropriate driver is not found.

/etc/sysconfig/hwconf is a text file that contains a list of hardware detected by linux (RedHat) during bootup. View this file using vi or your favorite editor and check if your network card has been detected.

#dmesg|grep eth

will let you know whether linux has detected the network card and found drivers for it.

Google for broadcom drivers.

I typed vi /etc/sysconfig/hwconf. and it had nothing of a ethernet card. How do i hardware detect or load drivers. i also did #dmesg|grep eth and nothing came up. i did a lspci -v and it came up with like 4 pages of stuff. didnt really know what i was looking for. i used the script command to put about 4 or 5 commands in a file. but i couldnt post the info cause i am not connected on the web which goes back to the orginal problem. I have an external hardrive but i dont know how to hook that up to linux either. but i am all ears for a hardware detect load some drivers. i just dont know how. i did download the drivers for the broadcom ethernet card for linux so dont know whats next but i aint giving up. I had no problem with redhat 7. it automatically detected everything i was good. but not with rh9. i will await your reply.
thanks

Remove the ethernet card, reboot your system into linux

Kudzu will(should) detect the hardware and request to configure the system. Select yes and let kudzu finish its job.

Shutdown your system, put the ethernet card back and boot into linux.

Check if kudzu detects the new hardware and configures RH9.

View /etc/sysconfig/hwconf and look for Broadcom or Ethernet entries.

You can

#lspci -v|grep eth

to search within the lspci list.
