Ethereal-users: RE: [Ethereal-users] Sniffing 802.11b using the Cisco 350 pcmcia adapter on Mand
Gino,
You are correct - later versions of the 2.4.X kernels included built-in support for PCMCIA services. You still need the pcmcia-cs package for tools like cardctl, but the kernel can handle PCMCIA services for you (if you are using modules, "lsmod" may indicate the presence of a module called "yenta_socket" if you are using the Linux kernel PCMCIA services).
That being said - many distributions have not switched to kernel PCMCIA services, instead still relying on the pcmcia-cs package for this purpose. I am not familiar with Mandrake and how it is setup - can someone else on the list chime in here on whether Mandrake 9 uses pcmcia-cs or yenta_socket?
Either way, you can use the drivers I listed for your Aironet card. If you are using the kernel pcmcia services, you will need to locate the airo.c, airo_cs.c and airo.h files in your /usr/src/linux tree, and (after backing them up) replace them with the links I provided. Then, rebuild your kernel modules.

And copied them into my /usr/src/pcmcia-3.2.1/wireless directory. Then I
rebuilt pcmcia-cs ("./Configure ; make all ; make install"), ran depmod and
restarted my PCMCIA services from the init script ("/etc/rc.d/rc.pcmcia
restart" on my system).
If you are using the kernel services for PCMCIA and drivers, just copy these
files over their respective counterparts in your /usr/src/linux tree and do
a "make dep modules modules_install".
Hope this helps.
