Hi,

I recently partitioned the hard drive on my PC and installed Redhat 9. I have XP on the other partition. While I am able to access the network and ping the netgear RP614 router from the XP partition as well as from another XP laptop linked to the router, I am unable to do so from Linux.

The PC has an Intel EtherExpress/100 NIC. The NIC was not automatically recoginized during installation but seems to be ok after I installed the drivers. Could this be causing the problem?

I setup DHCP through netconfig. dhclient returns with "No DHCPOFFERS received"

How do I find out if this is a problem with my NIC or with the router? The NIC/router work fine if I boot up XP.

Could you recommend a NIC that is automatically recognized by RH 9?

Here's the output of lsmod/ifconfig:

hi,
try assigning the IP address manually instead of getting it from DHCP.
also post the o/p of
#lspci

regards

I already tried assigning IP address manually with no luck...

Here's the output of the lspci command. I did install the drivers for e100. When I setup static IP address and ping the router, I do see the light at the PC/ethernet cable hub blinking. However, the ping times out. Any suggestions? Should I try getting a new router? Or replace the NIC?

your ethernet card has not been installed.
Check the company of you LAN card. Search for its module/driver on www.google.com. Now make sure its in /lib/modules/2.4.26/kernel/drivers/net/
note: 2.4.26 is my kernel, you may have different.

This is the module you have to insert into kernel using
#insmod <name of module without the extension .o>

regards

Well, I did install the drivers. insmod e100 returns module already exists.

Are you sure its the module your NIC requires ???
could suggest just a hit and trial method. Remove the module through
#modprobe -r <module name>
and then re-insert that.
If it still doesn't help and you don't get it working then change the NIC.

sorry to say that now i won't be able to help you anymore.

regards

Thanks ruudra.

I was finally able to resolve this problem. I selected to boot from RH 2.4.20-8 instead of RH 2.4.20-8smp. I did a make clean and install to build the drivers. insmod e100, lo and behold it started working.

Hence, it appears the drivers I downloaded for the e100 modules from the intel website may not be compatible with the SMP mode in certain cases.

hi,
nice to see that its working now
BTW what is 2.4.20-8smp ??? (particularly this smp)

regards

Here's some info on SMPs and hyperthreading:

http://en.wikipedia.org/wiki/Symmetric_multiprocessing
http://en.wikipedia.org/wiki/Hyperthreading

Intel® Pentium® 4 systems with hyperthreading will have an SMP kernel installed by default.
The Red Hat Linux (kernel version-smp) will boot by default.
