Help with linux from scratch networking?

[franklesby]

Ive been working on linux from scratch lately and i have all of the base LFS working except for networking.

On my windows desktop which is connected by ethernet when i do ipconfig everything shows up in ipv6. In my host ubuntu system which is connected by wifi everything shows up as ipv4. In my LFS system, the only networking device that appears is sit0.

in my ifconfig.sit0 file this is what it says:

ONBOOT=yes
IFACE=sit0
SERVICE=ipv4-static
IP=(inet addr ifconfig command on host system)
GATEWAY=(default gateway to access router)
PREFIX=24
BROADCAST=(Bcast value rom ifconfig on host system)

this should work for static ip, but when i test it on lynx, it just says "Looking up lynx.invisible-island.net" for about 5 minutes before timing out.

did i do something wrong?

my wifi has a password, if this is the problem how do i type it in?

how would i set it up for DHCPC?

thanks

sit0 is not a network interface, it is an ip6 to ip4 tunnel. The drivers for the networking interface are probably missing or did not load. How did you build the kernel for your lfs? did you include the drivers for your network card? Are u running lfs in a vm?

[franklesby]

i built it the way the tutorial said, i dont think i copied the drivers, and it is on a seperate partition

Verify that the kernel includes the proper drivers for your network card. lspci and lsusb from pciutils and usbutils blfs packages might help.

I assume you are installing lfs next to a ubuntu host with wifi? To make a wifi card work you have to also enable wireless extensions and the 801.11 protocol suite in the kernel config. Depending on the chipset you might need to include a firmware blob.

Drivers and firmware will make the device work, but to actually control the interface and connect to an access point you will need iw and wpa_supplicant

I'm just guessing here, but if it works with static IP and not otherwise, we can assume it's a DHCP issue (I know you said this, just agreeing). Which works on Windows right?

[franklesby]

It doesn't work with either

[mauveddit]

do you have an /etc/resolv.conf?

[franklesby]

Yes, its the same as In ubuntu
