Telat Bangun

Udah tiga hari ini sering bangun kesiangan. Ga biasa nya telat bangun sampai2 shalat shubuh jam 05.30 :( entah terlalu banyak pikiran bisa juga kecapean.

Maklum terlalu sibuk dengan pekerjaan hingga melalaikan suatu kewajiban sebagai makhluk ciptaan Allah. Ya Allah ampunilah dosa2 ku :(

Melindungi Diri dari Flu

Flu merupakan penyakit yang sering kita alami. Perubahan cuaca, kelelahan atau yg paling sering tertular dari orang lain. Walaupun sering dianggap penyakit ringan tetapi mengalami flu tidaklah menyenangkan :)

Flu atau influenza disebabkan oleh virus yg menyerang sistem pernafasan. Virus masuk ke dalam tubuh makhluk hidup kemudian menggunakannya sebagai tempat untuk berkembang biak. Flu bisa tertular dari jari2 orang setelah berjabat tangan atau bisa juga dari tertular secara langsung lewat udara dari si penderita.

Dengan kondisi demikian sewajarnya kita bisa melindungi diri dari kebiasaan yang dapat mengakibatkan kita mengalami gejala flu. Salah satunya dengan cara menjaga kebersihan lingkungan, mencuci tangan sebelum makan, olahraga dan selalu menjaga kesehatan tubuh dengan mengkonsumsi makanan yg mengandung nutrisi2 vitamin yg bermanfaat buat tubuh.

Jika sudah terjangkit flu, rekan-rekan dapat melakukan hal2 agar penyakit tsb tidak bertambah parah. Istirahat atau tidur dapat memperkuat sistem imun tubuh. Perbanyak minum air putih. Air putih dapat membantu tubuh agar tidak dehidrasi, karna saat flu banyak cairan yg dikeluarkan oleh tubuh.

Dengan melindungi diri dari flu, berarti kita melindungi keluarga dari sasaran penularan virus :) Jangan anggap remeh flu aka influenza dan hendaknya selalu meningkatkan daya tahan tubuh :)

Semoga bermanfaat :)

In this oppurtinity, i would like to share just information about sniffing. What is the sniffing ? Sniffing is a method to see the entire package of data passing on a communication medium such as computer connected to the lan, then the packets are reassembled so that the data submitted can be seen by people who do the sniffing.

Sniffing can be done because it is basically an ethernet connection is a connection broadcast, in which all host computers in a network group (eg cafe) will receive packets sent by a host computer.

In this case, how the sniffing is done in social networking applications.

Interconnection IPv4 and IPv6 with Automatic Mechanism Tunneling

With the development of internet technology is increasingly rapidly causing more and more internet users. But it added the internet user is not matched with the number of IPv4 addresses. So IETF issued a new IP protocol standard called IPng (Internet Protocol Next Generations) or also known as IPv6. IPv6 address format and has a different header with IPv4. So that IPv4 can not directly interconnect with IPv6.  This can cause problems in the implementation of IPv6 in the IPv4 Internet network that has been installed.  As  solution to this problem required an implementation of IPv6 transition mechanism for IPv6.  The aim of making this transition mechanism is so that IPv6 packets can be passed into the existing IPv4 networks or conversely.

Automatic Tunneling Mechanism functioning IPv6 packets pass through IPv4 network which has
there, without changing the IPv4 network infrastructure. Automatic Tunneling mechanism has a working principle encapsulates IPv6 packets with a header IPv4, then the package is immediately sent to the IPv4 network. The function of the encapsulation of IPv6 packets with IPv4 header is for the package can diroutingkan by routers IPv4. However with the addition of the IPv4 header is certainly going to increase in size, according to the packet length IPv4 header length is 20 byte. Accretion this package will also result in increased delay time the main paket. Question shipping of the implementation of IPv6 transition mechanism is the accretion time delay the process due to the length packets, the encapsulation process and the process decapsulation.

Automatic Tunneling Transition Mechanism has advantages :

  1. Easier in implementation.
    In the implementation does not require much computer, simply use a computer
    already there. especially for the gateway tunnel, the OS needs to be upgraded to the operating dualstack system which supports IPv6 and IPv4.
  2. It’s easier in terms of configuration at the operating system.
    In the configuration script is not needed a complex configuration script, simply by
    tunnel interface configuration and configuration of routing tables only.
  3. Does not require a server that serves the transition.
    In the implementation does not require a special server that serves the transition mechanism, encapsulation and decapsulation is done in a tunnel between the gateway and point-to-point.

Weaknesses :

  1. Can not be implemented if the client is in transition NAT router.
  2. Will cause added delay (processing time).
  3. Vulnerable to DDOS attacks.

Vulnerability in uploading photos in the cyber world

New York — For you who often upload photos on the internet, especially Twitter and Facebook started to be careful. Not only the risk of these photos revolved and utilized those irresponsible but your crime will also be lurking.

Because, through these photographs the criminals can know the existence of the virtual world location of the upload. Photographs taken from a camera phone and then instantly shared on Twitter, not only the image information alone, but could not save the information known to the upload.

The Next HOPE hacker conference in New York, a security expert demonstrated how it scans approximately 2.5 million images, spread the link on Twitter. Of that amount, he was able to mention the location coordinates (latitude and longitude) approximately 65 000 photographs, and that’s without known owner of the photo.

“This shows that have failed to safeguard the privacy,” said security expert Ben Jackson Labs as reported by Cnet Mayhemic, Saturday (17/07/2010).

The process of scanning photos to determine the coordinates of the position, made possible when the photo was taken from the phone. The current generation of mobile phone features geotagging photos. Geotagging is a process of geographical identification metadata in a media such as video, photographs, websites, the metadata will have coordinate information.

Hackers are able to inject into the EXIF metadata taken from photo cameras to identify the location. Actually, Twitter and other social networks have service to share locations but most users rarely turn it on. (Ugo)
