Can I deauthenticate multiple networks all at once? - linux

I can use aircrack-ng to send deauth code to one network but can I do it for more than one networks at once from the same device? If yes, How?

.
I tried running the code in two terminal windows but then my entire computer froze.

Windows program to communicate with Virtualbox

I am wondering if it is possible to write a program on Windows that communicates with a program within a Linux Virtualbox on the same machine. If this is possible, what is the best approach to doing this? Is there a way to do this without using the internet to communicate?
I found instructions showing how you could potentially use SSH, but I have never tried doing this before, so I do not know if using SSH to communicate would be the best option.
I was going to put this as a comment to a very vague question, but then it got too long.
It depends what you mean by "communicate"....
If the Windows machine should start a program on the Linux VM, you probably want plink.exe - see here.
If you want to transfer whole files, you probably want scp or FTP or FileZilla - see here.
If you want to send small messages occasionally, maybe netcat, also known as nc - see Netcat Cheatsheet here.
If you want full-on, high speed, continuous messages, maybe sockets or some messaging protocol like mqtt.
If you want to share data structures, like lists, queues or sets, you could allow both Windows and the Linux machine to access a shared Redis database - see here.
Or maybe it is enough to share a filesystem between the two machines - in which case you can make a Shared Folder in VirtualBox on your host and the VM can just mount that and read/write it. See diagram:

Transfer files between raspberry pi and Multiple Linux OS computers?

I am looking for a method to transfer files between Raspberry Pi and a computer with Linux OS on.
I need to do so without FileZilla file transfer.
I wonder if there is a script to do it automatically .
I have an array of files and a corrosponding array of IP's of the receiving Servers on a network how can i map the files to the servers and send them in turn .
any bit of advice is very much appreciated.
So you need transfers files from Pi to multiple Linux computers. If you only have a limited number of computers you need to transfer to, then you can do so manually for each computer, using the scp command.
For example let's say the you need to transfer all files with extension .c found in directory /foo in the Pi to the server named barserver in the directory /foobar. From the Pi you can run:
$ scp /foo/*.c username#barserver:/foobar/
Or equivalently from the server you can run:
$ scp username#piaddress/foo/*.c /foobar/
If you have so many servers that doing it manually would be tedious, then you could write a script.
Maybe it's a little overdone, but you may want to check out Fabric: Generally a deployment tool, but I'm using ist to handle all of my file transfers between all my 4 Raspi's, Uploading config files and starting/stopping services.

Can I run ndk-gdb connected to two devices?

I am trying to run two instances of ndk-gdb attached to two devices.
but based on this page, I can not find a way to do that...

Is it even possible to have two separate devices connected to two instance of ndk-gdb running over adb?

Is there a way to run FirefoxOS with multiple outputs (HDMI devices)

We are trying to get FirefoxOS to use multiple outputs (HDMI devices) simultaneously in the way to show applications running on either of the screens (presumably different apps on different screens). Has anyone tried it?
There's a proof-of-concept demonstration of multiple screen feature on Firefox OS.

X11 networking on linux

I know you can connect to a remote X11 server to use them like a local X11 system.
My question is: Can you connect multiple computers to work together and display (through their videos outputs) an unique instance of X11 desktop?
Or, another phrasing: Can you process and display an image using several X11 servers?
Take a look at Distributed Multihead X Project
X11 is a protocol. If you use it over the network, the GUI application that you run remotely, actually connects to your local X11 server. So yes, you can have multiple clients running applications on the server that display on different X11 servers. As for processing images using X11 server - what do you actually mean by that? The only thing comes to mind is multiple monitors. If so, then yes - you can use a dedicated X11 server per monitor.
If I understood your question correctly, you want to have multiple computers collaborate on displaying a single X11 display. This is not directly possible.
However, you can have multiple video cards in a single computer and use the Xinerama extension to have the multiple cards show a single logical X server. This can allow you to use a single machine to drive several monitors with ease. (With video cards that support multiple outputs, you ought to be able to get up to four or six monitors without too much hassle. Dozens might be very difficult.)
I can't think of any mechanism that would allow a single keyboard and mouse to reliably work across multiple monitors driven by multiple computers. But if your problem is significantly restricted (if it really is just viewing an image via several X servers), then you could write a client application that renders only a portion of the image and run multiple clients that each display only a portion of the image -- that when taken together, looks like the image is seamlessly displayed by several systems simultaneously. This is definitely a bit awkward though, as the coordination of the system will require some thought.
If you want to drag windows from one screen to another, or display a part of a window here and another part of it there, then no, this is not possible with existing out-of-the-box software. You can try to modify a "virtual" X server such as Xephyr such that it uses multiple backend X servers for portions of its framebuffer. This is not exactly trivial but should be much easier than writing your own multi-box X server from scratch.
If you want to clone one desktop to many displays connected to different computers, you can try running VNC or RDP clients on all displays but one.
