Hi all my problem is with the access network, when I start my LFS I get this message:

*****Bringing up the interface ... [FAIL]

running the command #ifup tells me:

*****Bringing up the interface... /etc/sysconfig/ifconfig. is missing or can not be accessed. [FAIL]

any opinion?

Do you have net-tools compiled and installed?

Did you try ifdown first, then ifup.

Did you check if your network card(s) are found by the kernel?
- dmesg | grep -i "eth[0-9]:"
- Or (you might need to install pciutils first, part of BLFS): lspci | grep -i eth

Did you create the ifconfig.ethX file(s)?

hi sorry for not answering before. I install all network packet and my IP configuration is:

1. running the command LSPCI:
...
01:00.0 VGA compatible controller: nVidia Corporation G86 [Quadro NVS 290] (rev a1)
06:03.0 Ethernet controller: VIA Technologies, Inc. VT6105/VT6106S [Rhine-III] (rev 8b)

1. etc/sysconfig/ifconfig.eth0

ONBOOT=yes
IFACE=eth0
SERVICE=ipv4-static
IP=192.168.1.44
GATEWAY=192.168.1.1
PREFIX=24
BROADCAST=192.168.1.255

2. my Kernel configuration:
...
->Ethernet driver support

[*] VIA devices
<M> VIA Rhine support
[ ] Use MMIO instead of PIO
<M> VIA Velocity support
...

3. running the command:
#dmesg | grep -i "eth0:"

[ 4.000625] via-rhine 0000:06:03.0: eth0: VIA Rhine III at 0x1b800, 00:24:01:a2:b1:43, IRQ 19
[ 4.001351] via-rhine 0000:06:03.0: eth0: MII PHY found at address 1, status 0x7869 advertising 05e1 Link 45e1

4. running lsmod:

Module Size Used by
...
via_rhine 22412 0
ehci_hcd 35684 0
mii 12595 1 via_rhine

when booting say:

Interface eth0 doesn't exist. [ WARN ]" or Bringing up the eth0 interface [FAIL].

Finally I could fix the network card.

1. Testing with eth0:
#ifconfig eth0
eth0: error fetching interface information: Device not found

2. Testing with eth1:
#ifconfig eth1
eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 metric 1

Rename file /etc/sysconfig/ifconfig.eth0 to /etc/sysconfig/ifconfig.eth1
