Description Frantz Dhin 2003-04-11 07:04:05 UTC
This report is addressed to the docs team as well as the creators of the 
livecds.
As per request on dev mailing list I started testing livecd-experimental-4-06-
03.iso. It looks uber-nice now. - Thanks a lot.

With that said I have a few comments on the setup procedure:
It took me a while to figure out that I actually had to type "gentoo doscsi" at 
the first prompt. Maybe this could have been more obvious.

While I do have an ethernet adapter in my PC then this is unplugged and I 
attempted to do the install over wireless. Maybe I overlooked something, but I 
did have to go through the following painfull procedure to get networking 
running:
Add "alias wlan0 prism2_pci" to /etc/modules.conf
Deactive eth0, if it is there.
modprobe prism2_pci
wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
wlanctl-ng wlan0 lnxreq_autojoin ssid=$myssid authtype=opensystem
ifconfig wlan0 (...)
route add default gw (...)

iwconfig on the livecd does not seem to work at all. For instance after the 
above config then I end up with for instance:
>iwconfig wlan0 channel 6
   Error for wireless request "Set frequency" (8B04):
    SET failed on device wlan0 ; function not implemented

I do not know how the wireless-tools package for the livecd is compiled. 
However, I can see that we are using 2 different kernels. "gentoo doscsi" 
results in a 2.4.20 series kernel being loaded, while there is also a 
2.4.21_pre6 kernel on cd. If the livecd creator is unaware of this I must say 
that 2.4.20 kernel contains wireless extensions 14, and 2.4.21 (since pre4 I 
believe) has extensions version 15. When wireless-tools are compiled they are 
compiled with these extensions, and while the tools compiled with version 15 
may work with a kernel with version 14 then it is not guaranteed.
For wireless-tools 25 patch level 15 is recommended. The 2.4.20 livecd kernel 
should have this patch, and it is available from wireless-tools homepage.

Suggestion: How about making the hostap drivers an option on the cd? They are 
not only for making access points. They work nicely as clients drivers for ALL 
wireless network cards based on Prism 2, 2.5 and 3 chipsets which is currently 
the majority of cards out there. The same story about wireless extensions also 
applies to the hostap drivers.

closing, since the older livecds are deprecated thanks to catalyst. I know that latexer plans on including wireless drivers for both hostap and linux-wlan-ng on a seperate wireless livecd, so if you want to get in contact with him, that would be cool.
