Jam WiFi

# This is a bash based wifi jammer. It uses your wifi card
# to continuously send de-authenticate packets to every client
# on a specified channel… at lest thats what its suppose to do.
# This program needs the Aircrack-ng suit to function
# – and a wifi card that works with aircrack.

I found this online, & I know it has some problems, but maybe we all could fix it up? I'm trying to get it working.
So far it says
jamwifi.sh: line 29: syntax error: unexpected "(" (expecting "then")

Any ideas?

 

This is it. I thought people here might find it useful if we could get it working.
https://code.google.com/p/wifijammer/ was the source, seems there is a v2
I'll check that out.

 

Ok the 0.2 version seems even worse off.
Do you think the code that I posted from 0.1 can be made workable?

 

Cool! Thank you. Ok I tried it out and it just would print : Run it as root
whether sudo or not, so I think I'll comment out that whole bit and try it again.

Hmm.. still no go

This part is screwing it up though

21: # Changes working directory to the same as this file
22: DIR=”$( cd “$( dirname “$0? )” && pwd )”
23: cd $DIR

jam_wifi.sh: cd: line 22: can't cd to
jam_wifi.sh: cd: line 22: can't cd to
jam_wifi.sh: line 1: syntax error: unterminated quoted string

I'm not great at this, but it would be cool to have this script work.
Basically I think that it "works" by sending Disassociate Packets to all MAC addresses.

 

Here is the original hackaday post of this
http://hackaday.com/2011/10/04/wifi-jamming-via-deauthentication-packets/with a video that might still work Still having problems for me, thank you Aby$m & Fantasma

 

In Xiaopan? chmod +x ?

Thanks I will give it a try now-

Ok cool the script runs and Option 1 works, it finds my WiFi and sets it, Option 2 to begin jamming process, I pressed 2, then it asked what channel so I try # 6 , but it just went back to the "select 1, 2, 3" menu, so no go, or is it doing it's thing in the background still? Thank you for working on this

 

Hi Aby$m, thank you for cleaning it up. It is pretty user - friendly right now, the scan function where you can see what SSIDs are using which channels in other versions was nice. I checked out your version of the script and I'm sorry to say that after picking wlan0 and option 2, channel 11 for example it goes back to asking me what channel again, but my wifi isn't doing anything in the background. In the script I see it's trying to run the aircrack-ng's commands in xterm, should these be opening in new terminal windows? Otherwise so far my LED light on the front of my 2W alfa does not blink rapidly when "jamming", and I don't see any traffic on another computer running monitoring, so maybe I have to fix something. I am using the Xiaopan 0.4.7+ for this. Are there any logs that I can post to help diagnose this?

 

Oh, is the problem that it would not work in Xiaopan? (Tiny Core)
Does it work in your Xiaopan Slitaz v2?

 

I'll try it out in Xiaopan Slitaz v2, thanks.

meknb : Have you checked this out with Aby$m's new script in Xiaopan?
