LFS 6.3 Ch 7.13 Udev Problem

I am at chapter 7.13 "Configuring the network script".

When I do the following to pre-generate the udev rules:

Code:

/lib/udev/write_net_rules all_interfaces

I get the error:

Code:

sed: can't read /etc/udev/rules.d/70-persistent-net.rules: No such file or directory

It seems that in that file should be the configuration information for my network card which udev has not detected. Is there a udev command that I can run so it will detect the ethernet card and populate that file?

If I do:

Code:

dmesg | grep eth

Than it outputs my card and chip, and correctly says the link is down.

Googling has not turned up the information I am looking for and I am lost. If I create the file then I get an error about the file already existing and that the rules will not be saved.

Can anyone point me in the right direction?

Thanks.

Just found your post (shame no-one replied :))- as I had got to that very section in the LFS 6.3 book and seemed to get the same error as you:

Code:

root:~# /lib/udev/write_net_rules all_interfaces

sed: can't read /etc/udev/rules.d/70-persistent-net.rules: No such file or directory

Then when I tried the second time:

Code:

root:~# /lib/udev/write_net_rules all_interfaces

/etc/udev/rules.d/70-persistent-net.rules exists, persistent interface names

not saved.

- We may have made a similar error somewhere else???

Typing "cat /etc/udev/rules.d/70-persistent-net.rules" gives:

Code:

# This file was automatically generated by the /lib/udev/write_net_rules

# program, probably run by the persistent-net-generator.rules rules file.

#

# You can modify it, as long as you keep each rule on a single line.



SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:02:e3:ab:cd:ef", NAME="eth0"

When I do "dmesg | grep eth" I get "eth0: link up"
BUT, I have not rebooted the system yet and am still running from the livecd which has setup eth0 itself- I am using a netgear fa330 by the way... What net card are you trying to setup?

Anyway, I couldn't figure it out - so I have moved on to the next stage. If I can't connect to the net later on I'll have an idea of where to start!
