Configuring eth0

[shankar96]

Hi!
Iam very new to LINUX;I donot even know the basics of it.I have a problem in setting up my LAN card(Realtek RL8139) on a REDHAT 7.2 system.The kernel version is 2.4.*(I donot know the number in place of *).Iam looking out for tips and rules of configuring the network card.Please provide me any/all info.Some of the info I collected is as follows:

"#cat /proc/pci" gives a large amount of data;I collected the relevant one:
Bus 1,device 2,function 0:
	Ethernet controller:Realtek Semiconductor Co.,Ltd. RL-8139 (rev 16)
	IRQ 11
	Master capable. Latency=32. Min Gnt=32,Max Lat=64.
	I/O at oxc000 [0xc0ff]
	Non-prefetchable 32bit memory at 0xd4000000 [0xd40000ff]


"#cat /etc/modules.conf" gives
alias parport_lowlevel parport_pc
alias eth0 8139too
alias sound-slot-0 i810_audio
<Some other info.>
alias usb-controller usb-uhci

The problem I have is that the explorer says "unknown host" for any address.Also Im not able to ping any address.It says your network card is not properly configured.Looking out for replies.

Can you post the output of lsmod please? Also how do you get your IP? Is it DHCP or statically assigned at the station?

Hi!
Sorry to ask,but what is lsmod and what is it meant for?Anyway the output of lsmod and cat /proc/modules is the same and is mentioned above.If IP address obtainig method can be obtained by looking at BOOTPROTO in "/etc/sysconfig/network-scripts/ifcfg-eth0", then it is dhcp.
It is also posted in the earlier code section.Actually, I want my IP address to be statically assigned by myself.The problem is that I would be denied access to the network if I were on a diferent IP address.
