[Clfs-support] Still No Internet

[Dan McGhee]

I'm sorry, but this will take awhile to read.

I've completed the CLFS-SVN-20091015-x86_64-Multilib build and am trying 
to move on to CBLFS.  My problem is that I cannot get connected to the 
internet.  This is all the networking that I want to do--and to connect 
when I'm travelling.  At home I have a Lynksys router wired to my PC.  
In the laptop I have an onboard wireless card with an Atheros chipset 
and a Linksys usb device.  I can connect with both of these using my 
Ubuntu-9.04 host system.

I don't think I have a driver problem because neither wireless device 
connects and if I issue <iwlist scan> each device can "see" the router.

Since I want only the dhcp client, I installed dhcp-3.1.0 using the 
instructions in the CBLS wiki.  I configured it by "copy and 
paste"--made the /etc/dhcpcd.conf file and installed dhcp from the 
clfs-pre8-bootscripts.  I rebooted the whole system and the network and 
dhcp failed to start because of a lack of "service" files in 
/etc/sysconfig/network-devices/ifconfig.{eth0,wlan0,wlan1} directories.  
BTW, eth0 is my LAN nic, wlan0 the wireless card and wlan1 the usb device.

I then went to the CLFS book Chapter 12.7 Networking Interface 
Configuration and followed the directions there.  I installed the dhcpcd 
service and wrote the ifconfig.*/dhcpcd files.  To try to keep things 
clear, at this point, dhcp-3.1.0, dhcp init script and dhcpcd service 
are installed.  I can post the startup error messages if anyone wants 
them, but the network failed and dhcp failed to start.

I found "service-dhclient" in the boot scripts so I installed that and 
removed dhcpcd service.  I also changed the ifconfig.* scripts to 
dhclient. Now when I try to start the network, I get the message:

"Bringing up the wlan0 interface....
NET: Registered protocol family 17
[OK]
Starting Dhcp version etc,etc,etc
[FAIL]"

It times out.

When I run <dhclient wlan0>, I get:

DHCPDISCOVER on wlan0 255.255.255.255 port 67 interval 5
...this is repeated with interval 7, 11, 21, 14 and 3...
No DHCPOFFERS received
Sleeping

I tried to set up like dhclient in Ubuntu, but couldn't find all the 
stuff I needed.  I've found nothing helpful on google, the mailing list 
archives, hints or wiki's either in CLFS or LFS.  Since I haven't found 
any correspondence on this subject in the archives, I'm assuming that 
there must be something wrong in the way I have applied the bootscripts 
or setup my configuration.

My final installation is this: dhcp-3.1.0, dhcp init script and dhclient 
service.

If anyone has a configuration using dhclient, I would appreciate your 
sharing it with me so I can try it.  I would also be grateful for any 
additions, deletions or edits to my current situation.

If it's relevant, I do have Network packet filtering configured for the 
kernel.  I have no clue whether this helps, hinders or is neutral.


Thanks for wading through this.
