How to add Swap Memory into uBuntu ..



Linux RAM is composed of chunks of memory called pages. To free up pages of RAM, a “linux swap” can occur and a page of memory is copied from the RAM to preconfigured space on the hard disk. Linux swaps allow a system to harness more memory than was originally physically available. 

However, swapping does have disadvantages. Because hard disks have a much slower memory than RAM, virtual private server performance may slow down considerably. Additionally, swap thrashing can begin to take place if the system gets swamped from too many files being swapped in and out.

Check for Swap Space


Before we proceed to set up a swap file, we need to check if any swap files have been enabled on the VPS by looking at the summary of swap usage.
swapon -s

An empty list will confirm that you have no swap files enabled:
Filename    Type  Size Used Priority

Check the File System


After we know that we do not have a swap file enabled on the virtual server, we can check how much space we have on the server with the df command. The swap file will take 512MB— since we are only using up about 8% of the /dev/sda, we can proceed.
df
Filesystem     1K-blocks    Used Available Use% Mounted on
/dev/sda        20907056 1437188  18421292   8% /
udev              121588       4    121584   1% /dev
tmpfs              49752     208     49544   1% /run
none                5120       0      5120   0% /run/lock
none              124372       0    124372   0% /run/shm

Create and Enable the Swap File


Now it’s time to create the swap file itself using the dd command :
sudo dd if=/dev/zero of=/swapfile bs=1024 count=512k

“of=/swapfile” designates the file’s name. In this case the name is swapfile. 

Subsequently we are going to prepare the swap file by creating a linux swap area:
sudo mkswap /swapfile

The results display:
Setting up swapspace version 1, size = 262140 KiB
no label, UUID=103c4545-5fc5-47f3-a8b3-dfbdb64fd7eb

Finish up by activating the swap file:
sudo swapon /swapfile

You will then be able to see the new swap file when you view the swap summary.
swapon -s
Filename    Type  Size Used Priority
/swapfile                               file  262140 0 -1

This file will last on the virtual private server until the machine reboots. You can ensure that the swap is permanent by adding it to the fstab file.

Open up the file:
sudo nano /etc/fstab

Paste in the following line:
 /swapfile       none    swap    sw      0       0 


To prevent the file from being world-readable, you should set up the correct permissions on the swap file:
sudo chown root:root /swapfile 
sudo chmod 0600 /swapfile

Raspberry Pi Wireless Attack Toolkit


Raspberry Pi Wireless Attack Toolkit
A collection of pre-configured or automatically-configured tools that automate and ease the process of creating robust Man-in-the-middle attacks. The toolkit allows your to easily select between several attack modes and is specifically designed to be easily extendable with custom payloads, tools, and attacks.
The cornerstone of this project is the ability to inject Browser Exploitation Framework Hooks into a web browser without any warnings, alarms, or alerts to the user. 


We accomplish this objective mainly through wireless attacks, but also have a limpet mine mode with ettercap and a few other tricks.
Limpet Mine Mode:
Poisons a network with ettercap + runs MITM Attacks
Passive Wireless Mode:
Free Wifi anyone?
Agressive Wireless Mode:
Become every access point with hostapd-karma
Once the RaspberryPi becomes the gateway, it fires up a MITM DNS server, metasploit, BEEF, and an injection proxy server for HTTP which injects the BEEF hook. From there, you log into the beef console and start popping shell.
It's in Alpha, so complain about things you want to see in it now.

Updated version: 2.0

Changelog Version 2.0
Code:
* Reviewed all tools.
* Compatible with Backtrack 5 R2/R3.
* Removed the menu.
Code:
git clone git://github.com/sickn3ss/backtrack_update.git
cd backtrack_update
chmod a+x backtrack5_update.py
./backtrack5_update.py
Screenshot:



If you know more tools I could add to the script in order to update them please feel free to post them here.
Also if you find any bugs or have any feedback feel free to contact me in this thread. I will update the thread with each update to the script.

How to Upgrade Wine from the Older version to Wine1.5 on uBuntu

I am new to Wine and anything like it. I want to run the application "ATCS Monitor". When I installed ATCS Monitor I received an error message:

C:\windows\system32\wshom.ocx

Unable to register the DLL/OCX: RegSvr32 failed with exit code 0x1

-From Terminal-

err:typelib:sltg_get_typelib_ref Unable to find reference
err:module:import_dll Library ScrRun.dll (which is needed by L"C:\\windows\\system32\\wshom.ocx") not found


I can get through it by just ignoring it but I then have errors in ATCS Monitor.

First, upgrade to Wine 1.3.35. Wine 1.2.3 is almost a year old and is 
missing some very important updates. 

Second, do a search for the file in the directory $HOME/.wine I suspect 
that either it is not there or it is in the same directory as where the 
program installed. ...


Ubuntu and Ubuntu derivatives (such as Kubuntu) obtain software from packages which are stored in repositories. Ubuntu's default repository includes Wine, however if you want to stay up to date with the latest Wine package you can use WineHQ's by following these instructions.

Adding the WineHQ PPA Repository:

Open the Software Sources menu by launching the Ubuntu Software Center and selecting Edit->Software Sources. Choose the Other Software tab and click Add.
Software Center->Edit->Software Sources->Other Software
Then, copy and paste the line below.
ppa:ubuntu-wine/ppa

Warning: Beta packages

The 1.5 packages here are beta packages. This means they will periodically suffer from regressions, and as a result an update may break functionality in Wine. If the stable 1.4 Wine version works for you, then you may not want to use these beta packages.

Installing Wine:

Once you have added the WineHQ PPA Repository, you are ready to install.
To get the most recent Wine 1.5 beta, click this link to install the wine1.5 package.
To install the older, stable Wine 1.4 version, click this link to install the wine1.4 package.

Upgrading to a new version of Ubuntu

If you are upgrading the entire system, such as going from Ubuntu 11.10 to 12.04, you will need to come back to this page and add the repository again. The built in update manager will not switch the Wine repository automatically.

Alternative Command Line Instructions for Installing Wine:

It is also possible to add the Wine PPA and install via the terminal. This may be useful on Kubuntu, Xubuntu, and other Ubuntu derivatives.
sudo add-apt-repository ppa:ubuntu-wine/ppa
Then update APT package information by running 'sudo apt-get update'. You can now install Wine by typing 'sudo apt-get install wine1.5'.
If you'd like to browse the PPA manually, you can visit its Launchpad page.
