WPA key and general BT question

[Oblivion_Zero]

MY FIRST and most important problem is this:

I was testing an ARP replay attack to get a WEP key, and left it running overnight... but when i got up and checked it, all the space i had left in my 8Gb USB (which i used to install BT on) had been consumed. So now i cannot even open konsole or wicd or anything, i think bcz I used up all space, and it gives back an error. I didn't write it down, because I thought it would be a common error, it is along the lines of "can't write anything" so I think it's bcz of lack of space, if there are other errors, then I will type what the error window says.

My question is, how can i get rid of useless things, or things that may have been written overnight, to free some space so i can use BT again .

Second thing is... so yeah I've been reading a lot, I learned how to get WEP keys, because I thought my modem used WEP, but OMG after I learn how to do it and test it a couple of times, I sadly go back to testing it in my own modem and when I check security setup IT'S FRIGGIN WPA!!!

I've been reading some tuts, specially aircrack-ng's site, and it's really complete (love the g0tmilk's video, thanks hypervista), but while reading, I've seen I need to brute force the pass.

I'm running BT4 from an 8Gb USB (because i mainly need it just to find out my own modem pass, so I didn't partition my hard drive or anything), so I cannot (or think i cannot) use a password list, such as ones with all hex code, which are bigger than 30 Gbs.

So I notice there are programs which can compile a list on the go, for the other programs to use and test. I've read some codes which I could compile myself, to for example use a list being compiled on the go with 10 possible chars (using letters and numbers) for WPA brute force.

The thing is, that I wanted to ask all you saavy BT forum members, if anyone could help me find out how to make such a program or use one, that could produce this keys on the go, BUT (and here's my problem), I wanted one that could produce a list, which only changes some numbers and letters, and keeps some the same.

I want to illustrate an example:

I know the key Is something along the lines of m001xxxxxxxxxx, the x's bein the changing chars, between numbers and lower cap letters. So to reduce times, and space being used in my hard drive and USB, I wanted to check if anyone could provide me to a link of a program which could produce such a list with varying keys which start with m001, or could give me a set of instructions to compile it myself.

Thanks before hand to everyone that helps in this forums.

Delete them.

That might seem like a intentionally smart assed response but it isnt any more complicated than that. You probably need to work on your basic Linux skills so you can work out how to go about this.

If it was me I'd do it with perl, but I think crunch can do what you want.

yeah, Crunch can work with templates.

The example below will give you all passwords comprising upper and lower case letters and digits exactly 8 characters in length beginning with 'abc' and ending in 'xyz'

./crunch 8 8 -f charset.lst mixalpha-numeric -t abc@@xyz

Unfortunately, it still doesn't seem to work with variable length passwords. You could try this, I guess:

./crunch 1 8 -f charset.lst mixalpha-numeric | sed s/^/m001/
