Issue at chapter 7.2.1 of LFS book 7.1 - networking
 
Hello everyone,
I'm actually at chapter 7.2.1 of LFS book 7.1.
When I execute:
Code:
for NIC in /sys/class/net/* ; do
    INTERFACE=${NIC##*/} udevadm test --action=add $NIC
done
I get:
Code:

(The message has been a bit truncated)
And when I use:
Code:
root:/# cat /etc/udev/rules.d/70-persistent-net.rules
I get:
Code:
cat: /etc/udev/rules.d/70-persistent-net.rules: No such file or directory
Someone know why I get these errors? Did I miss something in the LFS book?
Thanks in advance

Just a wild guess: Are you still doing these actions from within the chrooted environment?

Yes, I entered in chroot with:
Code:
chroot "$LFS" /usr/bin/env -i \
    HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
    PATH=/bin:/usr/bin:/sbin:/usr/sbin \
    /bin/bash --login

If you are in a chroot have you mounted sys proc and dev form the host system to your chroot environment?

ie:
Code:
mount -vt proc proc ${LFS}/proc
mount -vt sysfs sysfs ${LFS}/sys
mount -v -o bind /dev ${LFS}/dev

chroot "${LFS}"

It seems that I forgot:
Code:
mount -v -o bind /dev ${LFS}/dev
But even when I mount dev, I still get the same errors...

Keith Hedger 08-06-2012 03:50 AM
I used the CLFS book so I am guessing but I don't have the file "/etc/udev/rules.d/70-persistent-net.rules" nor is it in /lib/udev/rules.d but my network works fine, do you have more than one network device? if you don't it probably doesn't matter about this bit ( judging by the blurb at the start of the chapter ), I only have one network card so I can't help much more, one final tip though you said you had forgot to mount dev, so why not put the code you need to mount the virtual file system and chroot commands into a script and run that, I did and it saved a lot of mucking about.

I would confirm the status of the device's driver. Most wired NICs (that I know about) use drivers provided by the kernel. That is very likely so for your NIC, or you would know otherwise from dealing with it in your host system. But perhaps the NIC's driver "is not set" in your LFS kernel config. Or, perhaps it is compiled as a module ("m") but has a module loading issue.
