bruse · 03-21-2005, 04:28 AM

i am using mandrake 10.0..
that is working fine...i have one problem...

i made one custum kernal compilation after that no internet connection...

the file having...
# /sbin/ifconfig

lo Link encap:Local Loopback

this is only i am having....

#/sbin/ifconfig eth0 10.255.240.119
there is no such device or addres..

i think the modules have to load so...

so to do that please help me....

iZvi · 03-21-2005, 05:26 AM

You either compiled your network card driver as module or you haven't included support for your network card at all. First tell us what's the model of your network card.

Baldrick65 · 03-21-2005, 05:28 AM

Can you post the output of

Code:

# lsmod

just to make sure the module is in fact loaded.

please help me as well. i hope you don't mind bruse, coz i'm having problem like u as well. i'm using mandrake 10.0 have cable modem + router. Don't know what to do and wonder what the heck

mcd · 03-21-2005, 07:34 PM

bruse, this is your ethernet card:

01:0c.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

you need to include support for this device in your kernel, either built-in or as a module. if you know the name of the module, try adding it with modprobe:

modprobe real-8139

that will only work if you built and installed the module though. if you didn't, then it's time to recompile. (and please note, real-8139 is NOT the actual module you need, i just made up that name).

and thtr2k you should probably start your own thread and include info on how you configured eth0 - do you have a static ip? or do you use dhcp?

bruse · 03-21-2005, 11:56 PM

sir here i have to inderstand one thing.....
now i have two kernals...2.4.6 and 2.6.10.
i downloaded 2.6.10 from net and compiled it...

but old kernal also not working...
both are conflicted with eth0 .

so how to add the device driver exixting in my linux box...

if it is where is the modules?

help me sir...

mcd · 03-22-2005, 01:05 AM

alright, well use www.google.com/linux to find the name of the module (driver) that you need for your realtek card. i'm pretty sure it's 8139too or 8139cp. then open a terminal, like gnome-terminal or xterm, and type:

su
(enter your superuser password)
modprobe 8139too
lsmod

instead of 8139too you want to put the name of your module. now, this should work if you use your old kernel. as far as your new kernel, it depends on how you configured it when you compiled it. did you include support for your hardware? if so, did you build it into the kernel or include it as a module?

now, the rest of the question is: did you configure your net access? are you using dhcp or a static ip address? did you set that up? if so, how?

bruse · 03-22-2005, 01:30 AM

i have one module 8139too.ko
when i gaive £modprobe 8139too.ko
no such file ....
£modprobe 8139too.ko
the format not found..

what is this format now how to add....
i am using staic ip address...

thanks

bruse · 03-22-2005, 02:18 AM

my god....
as u suggested re-compile the kernal...
i did it but a big problm. when i reboot to the new compiled...

/lib/ext3.ko
could not load the module: -l module format not supported

kernal panic: no init found

it seems that could not load the file system modules.........

so how to rescue...
can u please tell me how to correct that using the linux cd...

i know how to mount my harddisk partiton...

can u please explain .....

please help me

mcd · 03-22-2005, 03:12 AM

Quote:

/lib/ext3.ko

sounds like you didn't include support for your filesystem this time. that's got to be built in to the kernel. i hope you kept your old kernel around. boot up a live cd and mount the hard drive like this:

mkdir /mnt/hd
mount -t ext3 /dev/hda2 /mnt/hd

then edit lilo to include a reference to your old kernel so you can keep hacking at your new kernel. edit /etc/lilo.conf, here's mine:

Code:

# Linux bootable partition config begins
image = /boot/vmlinuz
  root = /dev/hda2
  label = Linux
  read-only
image = /boot/vmlinuz-2.6.10
  root = /dev/hda2
  label = 2.6.10
  read-only
# Linux bootable partition config ends

where /boot/vmlinux-2.6.10 is my custom compiled kernel, and /boot/vmlinuz is a symbolic link to /boot/vmlinux-2.4.26, which is my default kernel.

and when you're done, save and close the file. then type lilo and hit enter.

bruse · 03-22-2005, 05:47 AM

yes i solved.....by go in to failsafe mode and added the modules at boot time...

now my output is like this....

now my problem is i have the IP address...and pinging well
but can not connect....

when i connect remote system..

#ssh 10.255.240.105
there are some outputs...that warrining me but not connected to remote system...

broadcast pinging within my system

but it is not showing the other clients.....

this means that my computer not connecting to LAN....

help me please....

mcd · 03-22-2005, 03:21 PM

hmm. i don't know what those inet6 addresses are...did you put those in on purpose? your ip addresses are funny numbers, are you using dhcp or a static ip? are you behind a router? maybe you haven't set your default gateway. my router's address is 192.168.1.1 so i type:

route -n

to see my routing table. if there's no gateway listed, then i can add one like this:

route add default gw 192.168.1.1

but that's only if you're using a gateway. i can't quite tell from your ip addresses, but i'm guessing you are.

bruse · 03-23-2005, 06:38 AM

no sir still not working the error is
