Urgent help needed

[edmundoab]

any linux experts around??

I need to get internet connection on my Red Hat 8
currently,
my network is on ethernet

but I checked in windows on the IRQ saying its 22
but the red hat only has up to 15.
even if I forces 22, it stats " device inactive "

any ideas how to set up my connection?
I am using an on board 3com

Is the proper module for the nic loaded?

You might want to fix your title. I guess a bug took out all mention of the problem...

 

[edmundoab]

well it was working before,
and now it isn't

no idea why...

Is that a yes or a no?

ifconfig -a

If eth0 shows up, chances are the module loaded. If it doesn't, the module didn't load. Did you make any changes recently?

 

[edmundoab]

yes eth0 is there

it can even detect the 3com,

changes?
erm, well I got a new wireless mouse.
but then I disconnected it as it was causing my keyboard to disfunction when I load the RedHat GUI

but why doesn't the IRQ 22 appear in red hat?

 

[n0cmonkey]

Does eth0 have the correct settings? If you are using DHCP, is the dhcp client program running and getting an ip address? Can you ping eth0's ip? netstat -rn should give you your routing table. If you can ping the eth0 interface from the RH box itself (and from your other machine if you have one), can the RH box ping your gateway? If that works, check your DNS servers. Did you do any troubleshooting?

I thought there were only 15 or 16 IRQs (0-14 or 15) on x86. I don't have anything above irq 12 on any of my machines.

 

[edmundoab]

yes using DHCP
but no IP address

netstat -rn is a command to run on the terminal?

I mean on windows..my win xp has from 1 to 22
the 3com is the last IRQ
I checked that on windows information..

 

[edmundoab]

it is shared with this thing called
standard-openHCD USB host controller

 

[n0cmonkey]

Usuallly anything in bold is a command to run on a command line.

Since it is using DHCP, make sure your dhcp client program is running properly. It is probably dhcpcd. So man dhcpcd and see if you can run it manually, or look at your init scripts to find the one that starts it. Check your logs to see if it recorded anything.

I don't know why Windows would be showing 22 IRQs. Like I said, I thought that x86 only had 15 or 16.

I don't think the USB controller would affect it too much, but you could try turning off USB and find out. I think the problem is somewhere else though.

 

[edmundoab]

ok thanks..
will try that,

i saw the kernel stating that the eth0 was not properly initialize

and check my network settings to find that the Primary and Secondary DNS has an IP detected

still no head way to solve it,

Any other errors or any hints as to what the problem is? What happens when you try to load the module manually?

and check my network settings to find that the Primary and Secondary DNS has an IP detected

Huh?

still no head way to solve it,

Have you tried anything beyond what I have posted here? Have you even looked at half of the posts I have made in this thread?

Is the module getting loaded?
What happens with your run the dhcp client?

 

[edmundoab]

module is loaded but i think it cant find the specific driver for my 3Com ethernet model

yes I have tried all the commands you wrote on the thread

btw, I meant , the Primary and Secondary DNS shows an IP address.
thats my point

 

[n0cmonkey]

I always thought the module was the driver.

 

[edmundoab]

you're talking about the eth0 right?
thats there..
but not the 3com specific model name was found.
and I cant find it on the web either.

 

[rmrf]

as root run the dhclient command and see what you get back from that. you can also try /etc/rc.d/init.d/network restart. or just make sure your modules are correctly initialized.

Linux identifies all ethernet controllers as eth. If there is only one NIC, it is identified as eth0, all subsequent NICs follow the same standard (eth1, eth2, etc). The module will be more specific, and you can look it up on RedHat's hardware compatibility list (I don't know which 3com NIC you have, so I won't do it for you). You can use lsmod to see what modules you have loaded.

Again, have you tried using your dhcp client manually? Is there some kind of output that might help track down this problem?

 

[drag]

After a reboot try a command like this from the command line (dmesg shows you the latest kernel-related messages, the same thing can be found in /var/log/messages file):

dmesg | grep eth

Or just look around with:

dmesg | less

If it your ethernet card shows up then your OS is aware of it and knows it's there. The problem would be somewhere else, this will help find out what exactly went wrong.

Also if you think it is a IRQ problem, your bios is suppose to handle that. Go into your bios setup and find were it asks about weither or not you use a plug-n-play aware OS. If it's on turn it off, if it's off then turn it on. Normally for both w2k, winXP and Linux you generally want that setting to be turned off. Plug-n-play like was touted in win9x is pretty much dead in the sense that it means anything nowadays, IRQ assignent and memory I/O assignment stuff is suppose to be handled by the BIOS, but some BIOS's are more braindead then others.
