Dear guys,

I recently bought a couple of cisco aironet wlan pcmcia cards from a second hand shop, it was a bargain so i got them two.

Now today I installed kismet on a laptop and noticed in the readme that the driver in kernel 2.4.19+ are quite unstable. I then downloaded a 2.4.19 kernel so I could use the card properly. Now I just have realised that if they say 2.4.19+ then that might mean that 2.4.19 might have a bad driver too hmmmm.....

Anyway I configured the kernel, did make dep, all went ok. Then I ran make bzImage amd the whole thing came with some errors, I will post them later on since the laptop is busy downloading something at the moment.

Then I downloaded a 2.4.10 to see if that was gonna work. Did tar -xjvf linux-2.4.10..... I could see a lot of text scrolling on the screen and at the end .... well the extracted kernel sources couldn't be found anywhere!? Now I thought that I might not have any space left on the hard drive so tried downloading other things to see and they all came down ok... Oh by the way if someone knows a good command to check how much space is left on a hard drive, that would be warmly welcome, I tried with fdisk and other stuff but in vain.

Ok sorry if this is confusing but all that mess came up just right now and i'm gonna make some research on google, I posted this in the meantime just in case I can't find some helpful answers.

Oh by the way, I'm running slackware 11 with custom 2.6.18 kernel

Thanks

df will show the free space on the disk, use the -h option to make the readout more human friendly. If your are running KDE there is a GUI tool as well.

Ok I've solved the tar thing, the problem was that it's been quite a long day =)

however here's what I get when typing make bzImage for kernel 2.4.12:

Thanks for that =)

Tried a 2.4.16 kernel since it seems to be the more stable one of the 2.4.10/18 range, got the same error message as above when trying to do a custom compile.

However this comes up when trying a default compile:

Anyone who's been reading this post should ignore it, the driver on the old kernel is actually just as buggy on those as it is on the new ones. I should have spent more time on RTFM....

My apologies guys
