In the video below this hacker was able to break the appstore model which prevents malware code, using a simple flaw in the iOS code signing enforcement mechanism. Very interesting goes to show no code is safe not even Apple!

Check out what the sign says in his room, great for inspiration.

Kevin Mitnick, the world’s most wanted computer hacker, managed to hack into some of the country’s most powerful—and seemingly impenetrable—agencies and companies. By conning employees into giving him private information and maneuvering through layers of security, he gained access to data that no one else could.

If you head on down to the Apple store this morning, you’ll spot some nice little spec bumps to the MacBook Pro range — without any increase to the prices. For a start, you can now splash out on a faster AMD Radeon HD 6770M discrete GPU with your 15-inch or 17-inch lappie. Even better, there are some CPU improvements to be had: the 13-incher gets the option of a 2.8GHz Core i7 or a 2.4GHz Core i5 dual-core processor, instead of the previous entry-level 2.3GHz i5 (and it also gets its HDD notched up to a minimum 500GB, or max 750GB). The 15-incher now goes up to a quad-core 2.4GHz i7 — the same speedy processor that comes in the updated 17-inch variant. Oh, the cost/benefit dilemmas.

Finding & Downloading Macbuntu

You can find a download link for Macbuntu at the project’s SourceForge homepage. To view the available packages, navigate to the Files page. Here you will find various versions of Macbuntu, for example Macbuntu for Ubuntu 10.04 and Macbuntu for Ubuntu 10.10 are two different packages. You must install the appropriate package for best results with your Ubuntu release version.

Install Outline

1. Download the correct version of Macbuntu for your version of Ubuntu.
2. Extract the contents of the Macbuntu archive.
3. Open a Terminal and navigate to the extracted Macbuntu folder.
4. Install Macbuntu by running the install script with the following command: ./install.sh
5. Follow the instructions and select your installation mode.
6. After the installation has completed it is recommended that you restart your computer, however, this is not required.

Installation Modes

Starting with Macbuntu v2.4, the installation script has become more automated and now offers express install modes for three different versions:

Basic

This mode installs only the basic components to achieve the Mac style interface. This includes Docky, GTK Theme, Backgrounds, Sounds, Cursors, etc.

Normal

This mode installs all available options that contribute to a closer Mac style. All components from the Basic mode are installed along with Compiz with many settings that help further transform your desktop into a more Mac styled environment.

Normal + Extras

This mode installs everything from the Normal mode and then applies a few extras that are not necessarily default Mac features or possibly not Mac features at all, but further eye candy: Wobbly windows, bottom-left corner becomes hot-corner for “Show Desktop”, bottom-right corner becomes hot-corner for “Expose”, icons in Dock zoom.

After Installing

After installing, you may want to have a look at a few customizations that you can make to your Macbuntu setup.

If you have more customizations that we’ve not listed, please let us know! You can file a request, however, you should file the request with “[Wiki]” at the start of the subject or title for further clarification. Please be as thorough as you can and provide any necessary steps and pictures if you can. You can your request here (and we’ll even mention you as the requesting user)!

The Canon MX330 is a low cost All-In-One Printer, Scanner, Copier, and Fax Machine. It comes with a CD with Windows and Mac OSX drivers and documentation. Not much help for those of us who have sworn off Windows and don’t own a Mac.

Fortunately Canon actually does supply drivers for the MX300 that work for Linux and Ubuntu/Debean. They are a bit hard to find and the installation is not documented at all as far as I could see. Here is a quick HOW TO. Where to find the drivers and how to install them.

First where are the drivers?

• Printer Driver
• Scanner Driver and Scan Program

Download the two tar.gz file that contain the dep files. Untar them and install them. On Ubuntu you can just open the location in Nautilus and click on the deb files (other methods will also work). I rebooted after the installs which I don’t think is actually necessary. After the print driver is installed power cycle the MX330 and Ubuntu should start the “CUPS configuration tool” (system-config-printer 1.1.3). You should now find the MX330 under the “Canon” menu item.

For the scanner the deb installs a program called “scangearmp” in /usr/bin, along with some libraries. I chose to add scangearmp to my Application/Graphics menu. Once the scangearmp program is installed you can use it to scan stuff. The program is also available from GIMP via the File/create/ menu.

I have so far had good luck with the MX330. I think Canon could have provided more documentation about the drivers and how to set them up etc. It was actually pretty simple once I had done it, but it took some trial and error work. I hope this helps you avoid some of the trial and error stuff.

May 19, 2010 Update

Thanks to Bennett Kanuka here is a solution if you are running a 64bit version of Ubuntu:

sudo dpkg -i --force-architecture cnijfilter-common_3.10-1_i386.deb
sudo dpkg -i --force-architecture cnijfilter-mx330series_3.10-1_i386.deb

The key here is the --force-arhetecture. Thanks Bennett.

I just wanted to post a blog on Homebrew because, I started loving it already. Homebrew is the new modern package management system for Mac OS X wich beats MacPorts. Yah! Homebrew is faster.

Homebrew is a Packaging system for Mac OS X 10.5 and above; heavy optimisations, no redundant packages and a bonus beer theme.

Here how you can install Homebrew on your Mac:

I prefer installing homebrew in /usr/local directory.

sudo curl -L http://github.com/mxcl/homebrew/tarball/master | sudo tar xz –strip 1 -C /usr/local

to avoid using sudo when installing packages, change the owner recursively on /usr/local directory

sudo chown -R `whoami` /usr/local

That’s it. Homebrew installed.

Now, Let’s install wget using homebrew

MacBook:~ abhinay$ brew install wget
==> Downloading http://ftp.gnu.org/gnu/wget/wget-1.12.tar.bz2
File already downloaded and cached to /Users/abhinay/Library/Caches/Homebrew
==> ./configure –disable-debug –prefix=/usr/local/Cellar/wget/1.12
==> make install
/usr/local/Cellar/wget/1.12: 9 files, 784K, built in 37 seconds

Really easy! isn’t it?

Have fun!

Note:
If you are facing problem because of MacPorts, try to uninstall it – Uninstall Instructions

and Do check out homebrew homepage on github: http://github.com/mxcl/homebrew

And one more thing, You should have xcode installed on your Mac – if already don’t have xcode, you can download from here – http://developer.apple.com/technology/xcode.html (Or you can install xcode from your second installation CD of Mac OS X)

How to search packages:

You can just type ‘brew search’ command or you can check all package formulas online here – http://github.com/mxcl/homebrew/tree/master/Library/Formula/

A wireless bridge connects two LAN segments with a wireless link. The two segments are in the same subnet and look like two ethernet switches connected by a cable to all computers on the subnet. Since the computers are on the same subnet, broadcasts reach all machines. DHCP clients in one segment can get their addresses from a DHCP server in the other segment.

Use a wireless bridge to transparently connect computers in one room to computers in a different room when you cannot—or don’t want to—run an ethernet cable between the two rooms.

A standard wireless bridge (client bridge) connects wired clients to a secondary router as if they were connected to your main router with a cable. Secondary clients share the bandwidth of a wireless connection back to your main router. Of course, you can still connect clients to your main router using either a cable connection or a wireless connection.

New in DD-WRT v24 is Repeater Bridge mode. This extends your primary LAN via secondary router (bridge router) and also allows wireless clients to connect to your secondary router. This extends the range of your wireless network while simultaneously allowing wired clients to connect to your secondary router.

Reference Image

In the case in which we are interested, a secondary router running DD-WRT v24 is configured as a Repeater Bridge between a Primary wireless router (of any make/brand/FW) allowing the above configuration.

Assumptions:

Primary router is configured in a 192.168.1.X subnet and leases DHCP address in the same pool. Secondary router is running DD-WRT v24

No security setup will be covered in this Wiki. It will be up to the user to setup security between the Primary and Secondary routers

Note: If you are unsure of what you are doing, is advisable to practice by setting up the router first in client bridge mode and get it working correctly. Client bridge mode is simpler but most of the settings are the same. Once you understand how to set up a client bridge and have it working, then proceed to setting up repeater bridge

Instructions

A very simple step-by-step description to connect a Router running selected DD-WRTV24 firmware in Repeater Bridge Mode. (This will work for almost everything, but do check notes on individual routers below clock).

Use Eko build 11296, with the milworm exploit patch, BS build 12533 or EKO 12548 builds to create a wireless bridge. DO NOT USE SP1 OR THE MAY 24 08 BUILD.

To enable bridge mode between two routers, the primary router must be in AP mode (default) with DHCP Server enabled. The secondary router running DD-WRT v24 will be configured as the Repeater Bridge.

1. Restore Factory Defaults on Secondary (DD-WRT) Router
2. Do a proper HARD 30-30-30 Reset on the router.
3. Set your computer to a static IP of 192.168.1.9
4. Connect to the secondary router via wired or wireless client keeping in mind the dd-wrt default settings for dhcp pool and ssid
5. Open the Wireless -> Basic Settings tab
   • Wireless Physical Interface Section
     • Wireless Mode : Repeater Bridge
     • Wireless Network Mode : Match Primary Router
     • Wireless Network Name(SSID) : Match Primary Router – Make sure you spell this correctly
     • Wireless Channel : Match Primary Router (This will disappear once you put it in RB mode, and isn’t needed)
     • Wireless SSID Broadcast : Enable
     • Network Configuration : Bridged
     • Save
   • Virtual Interfaces Section
     • Add
     • Wireless Network Name(SSID) : Different from Primary Router
       • [NOTE] – You CAN try using the same SSID but many have had random disconnects and/or no connection if the SSID’s are the same. If using the same ssid doesn’t work for you, use a different ssid from the primary router
     • Wireless SSID Broadcast : Enable
     • AP Isolation : Disable
     • Network Configuration : Bridged
     • Save
6. Open the Setup -> Basic Setup tab
   • Connection Type will be: Disabled
   • Set STP for Disabled (Enabled sometimes can cause connection problems) redhawk
   • IP Address : 192.168.1.2 (Assuming Primary Router IP is 192.168.1.1)
   • Mask : 255.255.255.0
   • Gateway: 192.168.1.1 (again assuming Primary Router IP is 192.168.1.1)
   • DHCP Server: Disable
7. Local DNS: 192.168.1.1 (if IP of Primary Router is 192.168.1.1)
   • Assign WAN Port to Switch : Checked or Unchecked – your choice. See note on Linksys (prefers checked) below clock.
   • Save
8. Open Advanced Routing
   • set Operating mode to “Router”
   • Set Dynamic Routing interface to “Lan & Wlan”
   • Save
9. Open Services
   • uncheck Dnsmasq
   • Save
10. Open the Security -> Firewall tab
    • Uncheck all boxes…except Filter Multicast
    • Disable SPI firewall
    • Save
11. Open the Administration tab
    • APPLY Settings
12. Wait for the router to reboot, and then when you can access the webgui again, uplug the power and plug it back in.
13. Once you have it working, go to the wireless security tab, and set the same type of security AND key for both the primary and the repeater ssids and hit apply.
14. Open the Status -> Wireless tab and click Site Survey. Join your primary routers wireless network. You need to do this only once.
15. SET YOUR COMPUTER BACK TO AUTO IP AND AUTO DNS.

You should now be able to connect wired clients and wireless clients to the newly configured Secondary router. They will receive IP Addresses from the Primary Router and will be able to use the Internet connection supplied by the Primary Router.

Also take note of the fact that all repeaters, including this Repeater Bridge mode, will sacrifice half of the bandwidth available from the primary router for clients wirelessly connected to the repeater. This is a result of the repeater taking turns talking to not just one partner, but to two, and having to relay the traffic between them. As long as your internet bandwidth requirements are within this halved bandwidth amount there will be little or no reduction in “speed”.
