Hi all,
Sorry for the length, if I knew what I was talking about it'd be shorter.
I have a wireless internet connection. I upgraded to LFS 6.7, trashing my old
6.3 system
and forgetting exactly how I got the wireless working :(. Hope someone can help.
Here's too much information:
0) Running Windows XP on my Toshiba Satellite P100-429 laptop. Internet
works fine in this environment. Have a wireless router from Cable&Wireless,
plugged into phone socket, getting good ADSL.
1) Installed LFS 6.7 on my laptop, dual-boots with WinXP, thank Grub.
For sect 7.11, my /etc/sysconfig/network file says "HOSTNAME=HAL9000".
For sect 7.12, I use a version of /etc/hosts appropriate for a no-card-setup:
127.0.0.1 HAL9000.discovery.ship HAL9000 localhost
For sect 7.13 I have done nothing except make a one-liner /etc/resolv.conf:
nameserver 10.0.0.2
(which is what my router likes to be called).
I have glossed over these sections because I don't understand them, and because
I
thought that subsequent messing with wireless-tools would work. If this is
wrong, please tell me
what I should be doing in these sections!
2) While in the kernel configuration menu, I selected my wireless card -
Intel PRO/Wireless 3945ABG. It seems to work.
3) In my BLFS environment, I install wireless-tools. I also downloaded
iwlwifi-3945-2.ucode from www.intellinuxwireless.org, and threw it into
/lib/firmware. So far so good?
4) I've messed about with the network script in /etc/rc.d/init.d. I added
these lines to the 'start' case:
ip addr add 10.0.0.3/24 dev wlan0
ip route add default via 10.0.0.2 dev wlan0
iwconfig wlan0 essid CableWireless
iwconfig wlan0 key E33841AB87457316E04FC930C2
ip link set wlan0 up
and this to the 'stop' case:
ip link set wlan0 down
5) So, once I'm booted up I test as follows: "ip link" gives
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether 00:16:36:88:35:0b brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
link/ether 00:18:de:2d:1d:31 brd ff:ff:ff:ff:ff:ff
4: sit0: <NOARP> mtu 1480 qdisc noop state DOWN
link/sit 0.0.0.0 brd 0.0.0.0
while "iwconfig wlan0" gives
wlan0 IEEE 802.11abg ESSID:"CableWireless"

Pinging 10.0.0.2 gives:
PING 10.0.0.2 (10.0.0.2): 56 data bytes
64 bytes from 10.0.0.2: icmp_seq=0 ttl=64 time=2.560 ms
[...etc...]
--- 10.0.0.2 ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max/stddev = 2.444/2.628/3.167/0.272 ms
but pinging, say, www.linuxfromscratch.org gives this:
PING quantum.linuxfromscratch.org (216.171.237.234): 56 data bytes
ping: sendto: Network is unreachable
ping: sendto: Network is unreachable
[...etc...]
--- quantum.linuxfromscratch.org ping statistics ---
0 packets transmitted, 0 packets received, [ctrl-C'd out]
I am also trying to install the X-window system at the mo, and failing at
the first hurdle: wget can't download the files for the X-protocols, again
telling me 'Network is unreachable'.
What's most puzzling to me is that I seem to be able to resolve domain
names! So communications must be working at least up to my ISP's DNS servers.
But it can hardly be a problem at their end if my WinXP system connects OK.
So... what am I missing?
