airodump-ng: input/output error


Recommended Posts

Hey techies,

I'm a newbie who's fascinated by Kali. My friend and I were trying to

pentest his network when we got these errors:

"bash: /usr/sbin/airodump-ng: input/output error"

And when I tried to open iceweasel I got yet another error:

"Failed to execute child process "iceweasel" (input/output error)"'

What is the problem and how do I rectify it?

Please remember that I'm a tyro and am just getting my feet wet in this

fascinating world of White-Hat-Hacking. So please lay it down nice and slow

- in English!

Any help will be highly appreciated.

Sounds like you ran out of memory. Since you're booting a live disc off USB, and your system looks to have a small amount of ram, depending on the ISO you used(they have instructions to make a mini-iso as well), you're most likely doing something that has eaten up all the ram since these boot into memory using a ramdisk. Alternatively, you could try installing it locally and dual booting into kali, which will have better results, but you're system alone for windows 7, should be slow as shit with those specs to begin with. 4GB RAM would be recommended for Windows 7 alone.

While Kali doesn't need more than about a gig(if natively installed), this would need more if using in a live disc, since that 1GB of ram is used for the expansion of the OS itself + whatever else you are doing, scanning, logging, etc.

input/output error is just that: A problem with storage.

You must keep your USB boot device inserted for the duration otherwise this is the sort of thing that would happen. If you did that it means that either the USB socket is kinda flaky or the storage is itself corrupt. So try a different USB port and if that didn't change anything re-write the image to the USB device. Also, verify the checksum for your download (which you should've done anyways) to make sure the corruption didn't occur there.

Memory isn't the issue here - your errors would've been different. Plus, 4 gigs to run Linux is *PLENTY*! Many ARM machines (Pi's and what not) make do with 512MB and run just fine.
