NIC recognized, but not connecting to Net. Help


My network card seems to be recognized by RedHat 7.2. I have a compac NetFlex-3/P. When I go to the networking devices, it seems to have been detected. It recognizes it as a ThunderLan. But when I can not connect to the internet. I'm connected to the university's ethernet, so everything should automatically set itself like XP, right? Or is there something else that I am missing?

Thanks.

Now it doesn't even recognize my NIC. When I run the ifconfig -a command, it only gives me the information about lo...nothing about eth0. I know the NIC is supported under Linux because I checked the Compaq website...the modules for the drivers is in tlan. I'm a newbie...how can I force my computer to detect my NIC? Thanks.

ifconfig

Hi Conman. I am a newbie as well but I think I can send you in the right direction so here goes.

I believe you can set your eth device by using ifconfig in this manner regardless of whether it detects it or not. Just remeber that linux will make do this regardless of whether it is correct.

ifconfig eth0 XXX.YYY.ZZZ.AAA netmask XXX.YYY.ZZZ.AAA broadcast XXX.YYY.ZZZ.AAA

example:

ifconfig eth0 123.456.789.12 netmask 255.255.255.0 broadcast 255.255.255.254

I hope this helps or at least puts you in the right direction.

Jason

I'm connected to Ethernet network. So aren't those values such as IP, netmask, etc set when my card attempts to connect to the network? I don't have a static IP. Or am I totally on the wrong track?

This is what the contents of /etc/sysconfig/network-scripts/ifcfg-eth0 are:

device=eth0
onboot=yes
bootproto=dhcp

yeah they will be given by the dhcp server and your network script is right. so if your card is recognised then it should work. lets see of your card is recognised. command "lsmod" gives the list of all modules loaded. you should find a module for your card. if you find one then you can do "ifconfig eth0 up". if it doesnt work then you should goto /var/log/messages and see for the error messages. if you dont find the module then you need to load the module using "insmod"

all the best

the only way i get get linux to recognize the NIC is if I add the following line to the /etc/modules.conf file:

alias eth0 tlan

is this correct? if i take that line out, then when i do the command ifconfig -a, eth0 does not show up as a device...only lo. when i do add the alias line and reboot the computer, during boot, the following error message occurs:

Bringing up interface eth0: Determining IP information: failed

And when I run ifconfig up, the error message: fetching interface information: Device not found

Thanks

that is correct ( if tlan is the correct module for your card )

It should work I am not sure what is happenening. why dont you try to install it and configure it form scratch. run kudzu, if it doenst give your card remove the line form module.conf file and the ifcfg-eth0 script and then run it again.

Redhat7.2 should be able to detect it and should be able to load its driver try it, other than that I dont know what to suggest,

I am sorry ...........all the best

Did the university give you a specific hostname to use (like ISPs do), or do they just let people connect without that sort of validation?

Also, what DHCP client are you running, dhcpcd or pump? Type "ps -ax |less" and to show your running processes and see if one of those clients are listed.


-just a couple of thoughts; it looks like you're doing everything else right...

Thanks for all the help guys. The university does not give a specific host. When I do attempt to run kuzdu, it does crazy stuff to my computer. The mouse jumps around the screen and when I move the mouse, the screen flickers. So I don't know what's wrong with that.

DHCP client? Doesn't RH automatically take care of that if I ask to use DHCP during netconfig?

Sounds like you have irq conflicts. If your mouse starts jumping, maybe your network card is trying to use the same irq as your mouse. Mine did but that was an old isa card. But I would check /proc/interrupts to find out if you have anything which might be conflicting.

It should, I'm just trying to cover all the bases.

If, as Mik suggests, you do have IRQ conflicts, try turnng off Plug-N-Play support in your BIOS.

I tried running the ps -ax|less command in attempt to find out if i was running dhcp or pump. I did not find any process that looked similar to either of the two. Could this be the reason the NIC cannot retrieve an IP address??? If so, what are the commands to force linux to run dhcp? Other than that, the NIC is detected and there isn't any interrupt conficts.
