Howto setup USB wireless card
I've got a new Sid box, with 2.4.20-686 kernel. It has a 3c905c ethernet
card, and a USB wireless D-Link DWL-120 "card".
The 3com card works fine (it's how I'm on the net now to send this email).
I'm having trouble finding understandable basic documentation for
getting the wireless card working.
First, the modules included with the kernel don't include a module for
the dwl-120, but there are kernel modules for it in the package:
"linux-wlan-ng-modules-2.4.20-686", which are "drivers for wireless
prism2 cards". Unfortunately, there was a bug in them because of the gcc
transition in Sid. But Joey Hess to the rescue. About the time I was
discovering this bug, Joey was putting a fix in the ftp archives, so I
downloaded
ftp.debian.org/pool/main/l/linux-wlan-ng/linux-wlan-ng_0.1.15-6_i386.deb
which seems to have solved that immediate problem.
Then I did a "modprobe prism2_usb", and now usbview shows the dwl-120 as
a prism2_usb device.
However, I don't know where to go from here. I've never worked with two
NICs in a box before. I assume I'll have to make some sort of entry in
/etc/networking/interfaces and then restart /etc/init.d/networking, but
I have no idea what entries to make (dhcp desired on both NICs, but I
can go static on the dwl-120 temporarily if necessary to get me started).
I have the 3com attached to one network, and I want to have the dwl-120
attached to a different network. I want to be able to ssh into this box
from the dwl side and then download stuff from the much faster 3com
side. I guess that makes this box a gateway? a router? I guess this
means I need to learn about iptables? ip masquerading?
I'm pretty comfortable with Linux (Debian in particular), and am fairly
conversant with networking from an end-user perspective, but network
administration (setting up gateways, routers, firewalls) is just beyond
my experience/knowledge level, but not beyond my ability to learn. I
just need a "thin manual" introducing the concepts (what's a gateway vs
what's a router vs what's ip masquerading vs what's iptables, etc, and
some general examples), and then perhaps some specific information as to
getting the right settings for this dwl-120.
I appreciate any and all responses (except the ones that say nothing but
"RTFM" - instead point me to which Fine Manual to read).
Thanks!
Kent
