no eth0 in 'ifconfig' on CRUX 2.1

Mr. Asdf · 07-14-2005, 05:37 AM

Hi, I've just installed CRUX 2.1, following the exact instructions in the CRUX Handbook 2.1 found on crux.nu, step by step.
when I got to the Kernel compilation (which is a thing I never did before). I did what I've been told here:

Quote:

Go to /usr/src/linux-2.6.11.7, configure and compile a new kernel.

$ cd /usr/src/linux-2.6.11.7
$ make menuconfig
$ make all
$ make modules_install
$ cp arch/i386/boot/bzImage /vmlinuz
$ cp System.map /

Remember to enable the following kernel options:

Code maturity level options --->[*] Prompt for development and/or incomplete code/drivers

File systems --->
Pseudo filesystems --->[*] /dev file system support[*] Automatically mount at boot

and when `make menuconfig` I was making sure those kernel options were enabled. I made no other changes in the kernel options except enabling ALSA. then when I loaded up CRUX, running `ifconfig` showed only 'lo'. then I tried to compile the kernel again, this time enabling PPP and making sure that Realtek PCI Ethernet Adapter is included there (as a module). again ifconfig only shows lo.
I have no clew what to do, maybe it's because I never compiled a kernel before, maybe because the kernel won't recognize my Ethernet network card, Maybe because I'm not doing what I need to do with the module (but what DO I need to do??...

)... I don't know...

anyway, my Network card is "Realtek RTL8139 PCI Fast Ethernet Adapter", kernel version is 2.6.11.7, and Modem is ECI ADSL B-FOCuS 312+ .

any help?

You either need to modprobe the module

Code:

modprobe module-name

or build the module into the kernel

The module should be called 8139too

so do modprobe 8139too
and dmesg to watch the result..

You will need to look at Crux's documentation to work out how to have it load at boot time.
Usually there is a file /etc/modules.conf or something similar with a line
alias eth0 8139too

first of all, I can get a working connection here!

did it with adsl-setup and some editions of config files. thanks!
but, there is a problem. I need to `modprobe 8139too` everytime I boot.
I tried adding the line:
alias eth0 8139too
and the line:
alias /dev/eth0 8139too
to /etc/modules.conf
and it doesn't seem to work.
I've looked at the documentation and if I understood it correctly it should be in /etc/modules.conf, I don't know why it isn't working. also, the file /etc/rc.modules is mentioned there, I also treid adding those lines to that file but it doesn't seem that this file is the right place for aliases. also looking at /etc/modules.devfs shows that it should be in /etc/modules.conf (and there is an include for that file there), but it still doesn't work.
any ideas??

What else is in the /etc/rc.modules file?

Mr. Asdf · 07-19-2005, 05:48 AM

Code:

$ cat /etc/rc.modules
#!/bin/bash
#
# /etc/rc.modules: module initialization script
#

/sbin/depmod -a

# End of file
$

Ok, looks like you need to add a command in the rc.modules file.. which is good..

Add modprobe 8139too before the depmod line..

And in modules.conf only have the alias eth0 8139too line..

works!

thank you for your help
