[DVB-S2] Tips & Tricks for the Cloud IBox II

1 Reply

 

Abstract

The Cloud Ibox II is a cheap affordable satellite receiver running Linux. It is priced between 90 and 130€. It features:

  • 2 x USB (although the case shows otherwise, it seems this is 1x USB 1.0 and 1 x USB 2.0)
  • Ethernet connection
  • DVB-S2 tuner
  • 1 x card reader
  • linux based
  • dreambox plugin compatible
  • price tag is between 90 and 130€ (often including a USB Wi-Fi Antenna)

It mostly comes pre-installed with a special version of the OpenPli 4.0 frontend. This is due to the situation that OpenPLI at this moment not yet supports the Cloud Ibox II. But I strongly hope this will come soon.

After tinkering with this device the whole weekend, we have some tips and tricks for the other users of this device. Continue reading →

[MacOS] Backup Chameleon Boot USB-Stick

1 Reply

1. Abstract

You have the situation that you installed Chameleon for security and compatibility purposes on an external USB-stick. For safety reasons you should consider making a backup. But all diskimaging (either Apple’s Diskutility, Carbon Copy Cloner or Super Duper) tools fail to create a proper backup since the bootblock is just not copied. So you end up with having to create a second usb-stick, but this takes time. So why not copying it? In the following article we’ll show you some basic steps to create a proper backup of your precious Chameleon bootable USB-Stick.

This session is not considered for newbies. You need to understand the steps and understand that you can completely destroy your system when you apply certain steps in a wrong way. The following steps comprise a forum threat on OSX86.net.

[WTF] Did Stuxnet Sabotage Iran’s Nuclear Facilities?

Leave a reply

Newspapers are full of speculations and details about this unique piece of software code, that obviously is a work by a government.Stuxnet used 4-zero-day exploits to infect computer networks running with Microsoft Windows. It was compatible to Windows 2000, Windows XP, Windows Vista and Windows 7.

The Register writes:

(..) the Stuxnet worm was programmed to probe the hosts it infected for extremely specific settings. Unless it identified the hardware fingerprint it was looking for in industrial software systems made by Siemens, it remained largely dormant.

Experts say the quality of code is very sophisticated, there are nearly no side effects. It is estimated that the costs of the development of a virus of that quality goes into the millions of dollars. It also shows a very detailed knowledge of the attacked facilities.

There are some indications that Iran’s nuclear facilities in Natanz were the target of that virus.

The downside is we suspect this is the beginning of large scale cyber attacks. I don’t think that western Nulear Facilities are safe from such attacks. Let’s all hope the best. This virus is simply a nightmare.

[MacOS] Chameleon On USB: Mounting USB Stick Correctly

Leave a reply

Inserting USB sticks to your Mac OS X based system makes Mac OS X mount the stick without assigning certain permissions like owners, or groups.

I. How things get mounted on Mac OS

The mount command on the terminal returns most likely some lines, like that:

  • testuser$ mount
  • /dev/disk0s2 on / (hfs, local, journaled)
    devfs on /dev (devfs, local, nobrowse)
    map -hosts on /net (autofs, nosuid, automounted, nobrowse)
    map auto_home on /home (autofs, automounted, nobrowse)
    /dev/disk3s1 on /Volumes/CHAMBOOT (hfs, local, nodev, nosuid, journaled, noowners)
    /dev/disk1s4 on /Volumes/Mac OS X Install DVD (hfs, local, nodev, nosuid, noowners)

You can see quite a lot of slices (i.e. ~partitions) are mounted to that system I am running here. For instance disk1s4 is the forth slice of disk1 and it countains an image of a Mac OS X Install DVD. And you can see a CHAMBOOT named drive mounted with several options.

II. Mount Options/Permissions

Our beloved USB stick named CHAMBOOT (contains Chameleon and) is disk3s1 and is mounted to /Volumes/CHAMBOOT. Mac OS handles USB mounting for most of our every day life operations fairly reliable. But this comes at a cost, as this simplicity is achieved here by applying options like nosuid and noowners during the mount process.

For people willing to run Chameleon from a USB stick permissions are inevitable, as for instance an Extensions.mkext kextcache can only be generated with proper file permissions being set.

II. Mounting USB with permissions

This just requires some simple mount operations being performed manually on the terminal. Do the following:

  • testuser$ sudo -s
    Become ultimate root now.
  • testuser$ cd
    Get back to the home folder whereever you’ve been before.
  • testuser$ sync
    Force completion of pending disk writes.
  • testuser$ umount -f /Volumes/CHAMBOOT
    This unmounts the USB stick called CHAMBOOT
  • testuser$ mkdir chamboottemp
    Create a temporary folder for our mounting session
  • testuser$ mount_hfs /dev/disk3s1 chamboottemp/
    Mount the USB stick to the temporary folder
  • testuser$ mount
    See how the drives are mounted now
  • /dev/disk0s2 on / (hfs, local, journaled)
    devfs on /dev (devfs, local, nobrowse)
    map -hosts on /net (autofs, nosuid, automounted, nobrowse)
    map auto_home on /home (autofs, automounted, nobrowse)
    /dev/disk3s1 on /Users/admin/chamboottemp (hfs, local, journaled)
    /dev/disk1s4 on /Volumes/Mac OS X Install DVD (hfs, local, nodev, nosuid, noowners)    You can see the USB stick is now mounted without “extra” options.

Now you can apply changes to the USB stick’s files in the proper manner (like copying files, repairing permissions and creating a kextcache). After having performed all the changes, you can correctly unmount. Read here:

III. Manually Unmounting

  • testuser$ cd
    Get back to the home folder whereever you’ve been before.
  • testuser$ umount -f chamboottemp
    Force to unmount the device mounted to the chamboottemp folder now.
  • testuser$ rmdir chamboottemp
    It is safe to delete the chamboottemp folder now.

[Pre] Marry me again: WebOS 1.2.1 syncs to iTunes 9.01

Leave a reply

A couple of days after their latest release of WebOS 1.2 Palm released WebOS 1.2.1. Now the Palm Pre is again synchronizing with Apple’s iTunes 9.0.1. Since iTunes version 8.2.1 with every update Apple is trying to stop Palm from syncing their Pre with iTunes. As we’ve seen in the past, all those attempts by Apple don’t last long. According to Precentral.net the Palm Pre uses Apple’s USB idVendor string to fool iTunes into thinking the Palm Pre is an iPod.

The WebOS 1.2.1 update features:

  • sync photo albums with iTunes
  • reducing size of photos on the Pre
  • bugfix for Microsoft Exchange Server 2007 sync

The update is 38MBybte in size and will be transmitted automatically on the Pre – at least in the USA.

[Pre] Merry Me again: Update Reunites Palm Pre with iTunes

Leave a reply

The “little Palm Apple battle” goes into its next round. A week ago Apple released iTunes 8.2.1. This update blocked Palm Pre users from synchronizing music and movies with iTunes. We reported about this update and the technical implications of the sync feature here.

Palm has now released a firmware update (webOS 1.1.0) for the Palm Pre. According to Palm’s blog entry this update contains the following features:

  • Exchange ActiveSync (EAS) (including remote wipe, PIN/password requirements, inactivity timeout, improved certificate handling and more)
  • support for emoticons in the messaging app
  • person reminders (“Next time you get a message or phone call from that person, a message pops up showing you a reminder to ask them about their vacation in Maui” ct. Palmblog)
  • and Palm webOS 1.1 re-enables Palm media sync with music, photos and videos with the current version of iTunes (8.2.1).

Got issues with the Update?

Our fellow Heise.de News (german only) recommend not to update your Palm Pre while it is connected to iTunes. In case you did that and your Palm Pre does not interact on USB anymore, do a hard reset with unplugging the battery.

[iPhone] iTunes 8 crashs Windows Vista

Leave a reply

Windows Vista users complain about complete operating system crashs resulting in blue screens. iTunes 8 for Windows seems to have the following issues, when using under Vista:

  • after connection an iPod Touch or an iPhone to the USB port: complete system hang up
  • CD/DVD drives disappear from Windows Explorer

But Apple already reacted and distributes now a fixed version. This implies you need to uninstall your current iTunes 8, then download the fixed iTunes 8 and install ii.

[MacOS] Boot native MacOS X with EFI-X USB Dongle

6 Replies

Update 26.06.2008: Read latest news about EFI-X here…
Update 22.06.2008: Read latest news about EFI-X here…

The newest on the market is announced to be released on 23. June. It is called EFI-X and seems to be quite a revolution. Technically it is a small USB dongle that contains a bootloader. That bootloader allows booting of native MacOS X installer DVDs or yet installed MacOS X installations…

Are you yet shackling your heads? Well, we are. It is said it will support any PC hardware to run OS X. At that point we are skeptical, since even Apple themselves are not able to support any hardware… We expect this to allow seamless installation on close-to-original-mac hardware. Which means: Intel Core2Duo on MoBo’s with Intel chipset and typical ATI or NVidia graphic adapters. But anyway: the installation will become simple and easy. No more BrazilMac workarounds or illegal downloading thru torrents from darkest places on the net. More features – as far as known yet – to be found in the updates section below the video.

We are quite curious about more details but currently the project’s website doesn’t contain anything more than we just told you. Netkas provides a video that shows the bootscreen. Sadly it is of poor quality and light, but see here:

Update (14.08.08):
Rumors on forums are telling about the specifications of your PC required to allow EFiX to run MacOS X

  • Intel Core 2 Duo (not likely to support AMD)
  • Intel chipsets on MoBo’s req
  • ALC889A or ALC885 audio chipset on MoBo to work out of the box
  • USB stick needs to plugged all the time (well who cares?)

Update II (15.06.08):
Althought not finished, the website of EFI-X.com has been updated during the last few hours. It seems, the following product versions of EFi-X will be sold:

  • EFiX for desktop computers
  • EFiX for notebooks
  • EFiX PCI version
  • EFiX complete systems

That looks promising. More to come at latest on 23rd…
Update III (16.06.08)
An FAQ has been published by the EFi-X Team. It clearly states, AMD CPUs are not supported, yet – as expected…
