الضربة القاضية لالفلونزا الخنازير

ذات صباح كنت أتابع بإهتمام شديد دكتور كويتي
 تحدث عن مرض
(H1N1) إنفلونزا الخنازير
وذكر أمور مهمه جدا
بطريقة سلسة سهله وقام بتجربة عملية
للوقاية من ذلك الفايروس بإذن الله
حفظكم المولى من كل شر
تعريف بسيط
بالبداية مرض إنفلونزا الخنازير ينتقل من الإنسان إلى الخنزير نفسه
فحين يتناول الإنسان لحمه يتكون لديه نوع من الفايروس ومن ثم تنتقل العدوى
من الإنسان إلى الخنازير
كالمزارع الذي يمتلك مزرعة خنازير فينقل المرض لجميع خنازيره عبر الإحتكاك بها أو السعال أو العطاس
حتى تصبح مصابة بذلك الفايروس
الأعراض
تكون مشابهة للإنفلونزا العادية ولا تظهر الأعراض حين الإصابة بل يأخذ المرض فترة
حضانة أيام ومن ثم تظهر علامات كإرتفاع الحرارة والإعياء .....الخ من الأعراض
كيفية الوقاية من ذلك المرض بإذن الله ؟
هنا الطبيب قام بتجربة عملية بمنتهى الروعة
 
بإمكانكم القيام بها بالمنزل
قام بإحضار
ورق تباع الشمس ومعروفة علميا بإسم
(PH - PAPER )
(متوفر بالصيدليات)
وأحضر أمامه
أكواب
الأول / وضع به ماء + ماده بيضاء سنعرفها لاحقا
الثاني / وضع به ماء فقط
الثالث وضع به مشروب غازي
وحين وضع شريط تباع الشمس بالكوب الأول أصبحت الورقة كهذه الصورة
لون غامق جدا
وبالكوب الثاني لم يتغير لون الورقة  ظلت صفراء 
أصبحت الكارثة وتحولت الورقة إلى لون أصفر فاتح جدا جدا
وبالكوب الثالث
بعد تلك التجربة
أوضح الدكتور بإن الوقاية من أي فايروس على وجه الأرض حتى السابق منها
كفايروس إنفلونزا الطيور وسارس )
تكون بجعل الدم ذا وسط قلوي لأن الفايروسات
ت! حب الدماء ذات الوسط   الحمضي
فالوسط القلوي لا تتحمله الفايروسات فتموت على الفور
سبحان الله
وأما الدم ذا الوسطالحمضي فهو بيئة ممتازة للفايروس
فورقة تباع الشمس حين تغير لونها للأغمق كان الوسط قلوي
وحين تغيرت للونالأصفرالفاتح كان الوسطحمضي 
إذا الوقاية تكون بجعل دمائنا ذات أوساط  قلوية
كيف ؟
أخبر الطبيب بإن أخذ ملعقة صغيرة جدا
ملعقة شاي ممسوحة
من بيكربونات الصوديومموجودة بالسوبرماركت
 
وهي تستخدم للخبز وإذابتها بكوب ماء ومن ثم شربها كفيلة بإن تجعل الدم قلوي
وبيئة تقتل أي فايروس على الفور سبحان الله
وهي مادة لا خوف منها أبدا ونأكلها يوميا نحن
عبر تناول الساندويتشات والخبز لأنها مكون رئيسي فيها
ونبه الدكتور على أن تناول الوجبات السريعة والمشروبات الغازية
والسكريات والشوكولاتة
هي عوامل مساعدة تجعل الدم حمضي على الفور
لإرتفاع الدهون فيها والسكر
بالتالي الدم يكون مستجيب تما ما لأي نوع من الفايروس حتى فايروس الإنفلونزا العادية

لذلك يجب التقليل من تناول ما سبق ذكره
بالذات لمن هو كثير إحتكاك بالأجانب
ملاحظة / حتى الآن لم يتم التوصل لمصل مضاد حتى وإن وجد سيكون بتكلفة عالية جدا جدا
تجربة مني
منذ أيام قليلة مضت إستيقظت و إذا بأعراض الزكام بدأت علي كإرتفاع بسيط بالحرارة والرشح
وفورا تذكرت حديث الطبيب وقمت بشرب كوب ماء مذاب به بيكربونات الصوديوم
وأقسم بالله وأشهده على ذلك سبحانه وتعالى إختفت الأعراض بعد ساعات قليلة جدا
سبحان الله
بعض ا لأشخاص يتخوف من الأضرار أو من كثرة إستخدام البيكربونات
رغم انه لاخوف منها أبدا شرط إستخدام
ملعقه شاي صغيرة جدا ممسوحة )
وإذا أردت ان تكون بالجانب الآمن إستخدم (المشروب ) في الأيام التي ستكون فيها
بإختلاط مع العديد من الأشخاص كالبنوك أو المستشفيات
 
أكد أطباء صينيون الثلاثاء أن إحتساء كوب من اليانسون الدافيء وليس المغلي
عقب الاستيقاظ صباحاُ
يعد أفضل وقاية من الاصابة البشرية من مرض انلفونزا الخنازير
الذي تفشى في بقاع شتى من العالم
وذكرت مجلة ( ميديكال ريسيرشيز) الصينية
المعنية بالشؤون الطبية
أن إحتساء اليانسون الدافيء يفوق في فاعليته تناول عقار
(تامفيلو) الذي طورته شركة "روش" السويسرية
ويستخدم حاليا على نطاق
 عالمي واسع
للوقاية من انلفونزا الخنازير
ذلك أن أحد المكونات الاساسية
المستخدمة في إنتاج ذلك العقار هو ( حمض الشيمكيك ) الذي يستخرج من قرن ثمرة اليانسون
ويترك عدة اسابيع ليتخمر

Run Internet Explorer on Linux

Most Linux users would be appalled by the idea of attempting to contaminate a Linux installation with any Microsoft product, especially Internet Explorer. However, many Web sites don't render properly using regular Linux browsers, such as Firefox or Konqueror. Other sites either require ActiveX controls or are designed to work only with Internet Explorer. Also, how can you test your new Web design and JavaScript for IE if you're an Apache and Linux maven?
For those who may have the need for Internet Explorer without the need to move to another machine or reboot, there is a solution for you: an extremely useful project aptly named IEs4Linux. In this article, I will describe how to install and begin using multiple versions of Internet Explorer using Wine and IEs4Linux.

What's IEs4Linux?

IEs4Linux is a small shell script that can be run via console on any Linux machine with Wine installed. As the title suggests, it allows you to quickly and easily install that most infamous of Microsoft products: Internet Explorer.
The creator of IEs4Linux is Sérgio Luís Lopes Júnior, a 21 year old Brazilian student and self-proclaimed lover of Linux and OpenSource. Naturally, being open source, IEs4Linux is free. However, as with many people working on open source projects, Sérgio's funding comes from the community; if you found IEs4Linux helpful, you can PayPal him a few dollars to continue development of the project.
IEs4Linux relies on the Wine project to supply an implementation of the Microsoft Windows API. The IEs4Linux script actually downloads the required CAB files directly from the Microsoft site; then, using cabextract, copies the files to a new Wine profile. This way, your existing Wine profiles are not affected, and any other software you have running will be just fine. In addition to installing Internet Explorer versions 5, 5.5, and 6, IEs4Linux also can install Flash 9 for you from Adobe.
IEs4Linux is a GPL product; however, Internet Explorer is a copyrighted product of Microsoft. This means that you will need to be in possession of a valid Windows license version greater than 95, although it will not be asked for during the installation process.

Author's note

For the purposes of this article, I'll assume you're running the latest version of Ubuntu as your Linux distribution. IEs4Linux will work with almost every distribution, but the installation routine varies. This article assumes that you already have Ubuntu Desktop installed and operational.
Depending on how you like to install your software, I have included two sets of instructions, first the graphical (GUI) method and lastly the console (CLI) method.

Installing the required packages

To install all the applications required to enable IEs4Linux to run properly, ensure that you have the Universe repositories enabled. Open the Software Sources configuration screen, which can be found under Toolbar | System | Administration | Software Sources.
Next, you need to select all the repositories for the CD-ROM/DVD option. You won't need this option. The online repositories are kept up-to-date, as shown in Figure A. Press the Close button when you're finished.

Selecting the required repositories to install Wine and cabextract.
Now it's time to begin installation of the required packages. Go to Toolbar | System | Administration | Synaptic Package Manager. Once it opens, search for Wine and cabextract. Once you find them, press Apply, as shown in Figure B.

Kickin' it old school with the console

You can also obtain the files from the console prompt. To begin, open a console. You can do this by going to the toolbar and going to Application | Accessories | Terminal. In the terminal, run the command: apt-get update && apt-get install cabextract wine. The install process will begin after pressing [Enter]. The apt-get process download installs all the files and packages for wine for you.

Getting down to business

Now that you have Wine installed with cabextract, it's time to download the IEs4Linux files. You can either go to the IEs4Linux Web site, or return to a console to enter this command to download the latest IEs4Linux build:
wget http://www.tatanka.com.br/ies4linux/downloads/ies4linux-latest.tar.gz Figure C shows what this looks like.

Figure C

Downloading the IEs4Linux Installer.
After you have downloaded the latest build tarball, you need to cd to the directory where you downloaded tarball to if you did not do so from the console. This can be done easily with the command cd ies4linux-*. Next, enter the command tar xzvf ies4linux-latest.tar.gz in the console to decompress the tarball and change directories into the build directory. Finally, to launch the IEs4Linux script that will begin the installation process, type ./ies4linux.
You will be lead through a text-based series of screens that will ask you questions about what versions of Internet Explorer you want to install, as shown in Figure D. The first question asked will be if you wish to install version 5 and 5.5 of Internet Explorer; you can make that decision for yourself. In addition to installing Internet Explorer, IEs4Linux will also install the Flash Player plug-in automatically.

Figure D

Running the IEs4Linux Installer.
After a few minutes, the script will download all of the required files and install them on your computer automatically. Additionally, links on your desktop will be created to Internet Explorer making for quick access. The Internet Explorer launch binaries will exist in the newly created directory bin in your home directory. For quick access on command line, run ~/bin/ie6 to launch Internet Explorer version 6. You'll see IE run, as shown in Figure E.

Figure E

You should now have Internet Explorer running in Linux.
Congratulations; you have successfully installed Internet Explorer version 5, 5.5, and 6 on your PC. With the assistance of IEs4Linux, it is possible to have Internet Explorer accessible to you as a tool on any Linux system that can run Wine.

Variations in other distributions

The install process for other distributions will be different according to that distro's package system. But the rest is the same after that. For example, in Gentoo, the series of commands would be:
emerge --sync && emerge wine cabextract. For Fedora, the commands to install wine and cabextract are:
yum -y install wine*
yum -y install cabextract
For Mandriva, the directions are:
urpmi wine cabextract For more distributions and instructions, please visit the IEs4Linux site.

Known issues

There are a number of known issues with the Internet Explorer version installed by IEs4Linux. Some of these include:
  • VML does not work.
  • PNG transparency does not work even when using hacks (a consequence of the "CSS filter" bug).
  • Windows Update does not work.
  • JavaScript error dialog does not open.
  • Modified toolbars are not saved.
  • ActiveX may not work with some special cases.

The install of Internet Explorer made by IEs4Linux doesn't have the JavaScript debugging enabled by default, which can be quite frustrating when you know there is a bug on the page, but can't get the error message. To get around this, you will need to enable JavaScript debugging.

In the menu bar, go to Tools | Internet Options to open the Internet Options dialog. Next, press on the Advanced tab and scroll down to the Browsing section. Uncheck the list item Disable Script Debugging.

Top 5 best practices for firewall administrators


At the recent Defcon 17 conference in Las Vegas, Tufin Technologies conducted a survey among 79 hackers, asking about their hacking habits. According to the survey results, the hacking business is just coming off its summer break and gearing up for the busy Christmas holiday season, so you'd better get ready.
Among the findings of the survey:
* Eighty one percent of the respondents are more active during the winter holidays than other times of the year.
* More than half of the respondents say Christmastime is the best time to engage in corporate hacking, and 25% specifically identify New Year's Eve as a great night for hacking.
"Christmas and New Year holidays are popular with hackers targeting western countries," according to Michael Hamelin, chief security architect for Tufin. "Hackers know this is when people relax and let their hair down, and many organizations run on a skeleton staff over the holiday period."
Although hackers don't mind working holidays, they seem to prefer having weekends off. The survey revealed that 52% of the respondents tend to work on weekday evenings, but just 15% do their dirty work on weekends.
You can't say that hackers lack confidence in their abilities. Ninety-six percent of the respondents say it doesn't matter how many millions of dollars a company spends on its IT security systems; it's all a waste of time and money if the IT security administrators fail to configure and watch over their firewalls. Eighty-six percent of respondents felt they could successfully hack into a network via the firewall; a quarter believed they could do so within minutes, and 14% within a few hours. Sixteen percent wouldn't hack into a firewall even if they could.
Are your firewalls vulnerable? Hamelin offers his best practices tips for reducing the risk of a hacking incident hitting your organization.
Document all firewall rule changes.
While this tip sounds like a no-brainier, firewalls do not have a change management process built into them, so documenting changes has never become a best (or even a standard) practice for many organizations. If a firewall administrator makes a change because of an emergency or some other form of business disruption, chances are he is under the gun to make it happen as quickly as possible, and process goes out the window. But what if this change cancels out a prior policy change, resulting in downtime? This is a fairly common occurrence.
Firewall management products provide a central dashboard that provides full visibility into all firewall rule bases, so all members of the team have a common view and can see who made what change, when they made it and from where. This makes troubleshooting and overall policy management much easier and more efficient.
Install all access rules with minimal access rights.
Another common security issue is overly permissive rules. A firewall rule is made up of three fields: source (IP address), destination (network/subnet) and service (application or other destination). In order to ensure there are enough open ports for everyone to access the systems they need, common practice has been to assign a wide range of objects in one or more of those fields. When you allow a wide range of IP addresses to access a large group's networks for the sake of business continuity, these rules become overly permissive, and as a result, insecure. A rule where the service field is 'ANY' opens up 65,535 TCP ports. Did the firewall administrator really mean to open up 65,535 attack vectors for hackers?
Verify every firewall change against compliance policies and change requests.
In firewall operations, daily life centers around finding problems, fixing problems and installing new systems. In the cycle of installing new firewall rules to solve problems and enable new products and business units, we often forget that the firewall is also the physical implementation of the corporate security policy. Every rule should be reviewed to understand that it meets the spirit and intent of the security policy and any compliance policies, not just the letter of the law.
Remove unused rules from the firewall rule bases when services are decommissioned.
"Rule bloat" is a very common occurrence with firewalls because most operations teams have no process for deleting rules. Business units are great at letting you know they need new rules, but they never let the firewall team know they no longer need a service. Getting into the loop on server and network decommissioning as well as application upgrade cycles is a good start for understanding when rules need to come out. Running reports on unused rules is another step. Hackers like the fact that firewall teams never remove rules. In fact, this is how many compromises occur.
Perform a complete firewall review at least twice per year.
If you are a merchant with significant credit card activity, then this one is not just a best practice but a requirement; PCI requirement 1.1.6 calls for reviews at least every six months.
Firewall reviews also are a critical part of the maintenance of your firewall rule base. Your networks and services are not static so your firewall rule base should not be either. As corporate policies evolve and compliance standards change, you need to review how you are enforcing traffic on the firewalls. This is a good place to clean up all those redundant rules that have been replaced by new rules, rules for services no longer used that you were not informed about, and all those temporary exceptions that were added to get projects, acquisitions, mergers and so on finished. The best way to keep bad things from happening is to not create an environment where they can.
