يوم البحر في اليابان 海の日 

يوم البحر: 

في اليابان يحتفل شعبها في ثالث اثنين من شهر يوليو بيوم البحر وهو عطلة رسمية لليابانيين،، يخرجون فيها للتنزه على شواطيء البحر ليعبروا للبحر عن شكرهم وامتنانهم   لدوره في تحسين الاقتصاد الياباني وتحقيق الرخاء، هذه العطلة هي عطلة رسمية مستحدثة بنص القانون الياباني،،، نحن ايضا كعرب بحاجة الى طلب مزيد من الاجازات لكي نتفرغ لشكر الله عز وجل على نعمة التي لاتحصى ولا تعدّ، ما يعني ان كل ايامنا ستكون عطلات رسمية (بنص القانون العربي) ماعدا يوم واحد هو يوم عيد الزواج لانه من الصعب ان تشكر احدا على هذا الموضوع، بل يجب ان يعتكف فيه بعض الازواج العرب للاستغفار... يتبع

This product, according to Apple CEO Tim Cook, will be a replacement for Notebook and Laptop. “I think if you’re looking at a PC, why would you buy a PC anymore? No really, why would you buy one?”, asked Cook, who recently revealed he travels with just an iPad Pro and iPhone.

The iPad Pro has some enhancements over iPad 2 including its expansive 12.9'' Retina Display, nearly doubled CPU performance of iPad2.  

It comes with many built in apps that are essential for individuals and enterprises as well as many others can be found on Apple Store which designed for iPad.

The design of iPad Pro includes the most advanced Retina Display. This iPad has the highest level of Resolution compared with the other iOS Devices. 

Top 10 Writing Resume Tips

Hello, 

Writing your CV is one of the most important and the first things to convince your employer. Here are some tips on how to write a good CV.  

Tip # 1: Write a clear objective in your CV: It is always important to be clear about what you are applying for. What will you provide to your employer (company)

Tip # 2: Don't use the same CV for all of your applied jobs: Try to customize you CV based on the job requirements. Each job has its own requirements, so never stick with the same CV. It's always a good idea to to consider writing your CV (job application) as a small assignment (1000 words assignment) 

Tip # 3: Make you CV very well organized: It is important to have your CV divided into sections and each section is highlighted with titles for each section (Qualifications, Professional Experiences, Soft Skills, etc). It is also a good idea to use bullets for writing brief details on your experiences, and don't write in very deep details. Leave that for your job interview :). Making your CV well organized will make your employers think that your job is also well organized and vice versa

Tip # 4: Write about your experience: When writing your experience section. Don't write any experiences that are irrelevant to the job description. Write your most current job first, then the next one and so on. Even if you don't have the exact needed experience, try to make it as close as possible. 

Tip # 5: Convince your employer: Try to show that you have done some volunteer works. This will give a good impression to your employer that you are a positive person. Hmmm, I encourage everyone to do that. If you are a fresh graduated, write about your graduation project, your lab experience, Software you used to work with in your study (such as Opnet, GNS3, SQL, Linux, etc)

Tip # 6: Watch your language: One of the most mistakes jobs seekers do is that they don't care about the language of writing their CV. People who are not Native English Speaker usually make some mistakes. In my point of view, these mistakes give your employers idea that you don't do your job perfectly. So, try to review your CV before sending it or ask one of your Native Language Speakers friends to review it for you. Also, try to make it simple and easy to follow. Don't skip between the main points 

Tip # 7: Write about your achievements: Include any prizes awarded in your previous career or in your education. 

 Tip # 8: Avoid writing anything personal details: Never write any personal details such as your ID Number, your religion, your nationality, ... etc

Tip # 9: Your Soft Skills: One of the most important things you can improve your career chance is to write some soft skills (Documentation, Presentation, Negotiation, Working well under pressure, ...etc. 

Tip # 10: Submit your application just before the dead line of the application: This will make your CV at the first of the applicants' list

That's all! and if you have been contacted for an interview, here are some short tips

1- When you are contacted and your employer tells you the time for interview, don't agree immediately on the appointment. Ask him to hold on a second to check your diary and see if there is any other appointment on that time, even if you know that there is no any :)

2- arrive on time and give your employer a call some minutes before you arrive. Don't arrive 20 minutes or more before time of interview (5 minutes are very good) to show that you don't waste your time. 

3- Have a Magazine or Newspaper while you are waiting in the reception. This also shows that you don't waste your time. 

4- During the interview try to make sure that you understand each question. If not try to use some expression to make sure (such as Do you mean....? Is it like....? ) Don't say what do mean or I don't understand. 

5- Finally, after the interview, you can ask if there will be any other meeting. Follow up your interview with a telephone call after some days. 

That's all! 

Good luck with your next career 

Windows Server 2012 AD DS Pre-Installation Configurations

After you finish installing Windows Server 2012, the following screen will show up

.

Click on the option number 1 (Configure this local server)

Change the Computer and change the name to be DC1 and leave it as a workgroup member, Notice that you will need to restart the machine.

 Change the IP addresses, time zone and any other configurations that suits your needs. The IP addresses I use for this lab is 10.10.10.0/24. Make sure you have disabled ipv6 if your organization has not yet started using it.

Configure updates as follows. Notice that you can configure the updates as you want, but that’s what 

I prefer.

 

Ok. Good! 

Next lab will be about how to install Active Directory Domain Service. 

Cisco DMVP over Frame Relay

Hello again,
One of my friends is trying to simulate DMVPN using Frame Relay. He had some issues to finish his lab. In this post, I'm gonna try to do this . So Let's begin :)
First of all we'll use GNS3 for achieving this lab. The components are:

1. One Frame Relay Switch ( representing the Internet Cloud)
2. Three Cisco Routers (37x) router 
3. Three connecting cables for connecting the routers with the frame relay 

Now, the steps are

• creating virtual circuits or Permanent Virtual Circuits (PVC)  inside the frame relay to map the traffic between R1, R2 & R3 . So how many PCVs do we need? Yes, two PVCs! R1>R2 and R1>R3 and the traffic between R2 & R3 will be passed through R1 which is the spoke.
• The Mapping of the interfaces show look like this

Cool. Now, connect port 1, port 2 & Port 3 with  s0/1 interfaces of R1, R2 & R3 respectively. The topology should look like this 

• Now, we need to configure each interface to work with frame relay and map the traffics of each interface to the specific DLCI interfaces. To do this, write the following commands under inter s1/0. Notice that !I’m assuming that all router use the interface s1/0 to ! ! connect to the Internet 

DMVPN

Under the interface s1/0 command, define the encapsulation to be frame relay and map each ip address wirh its specified dlci   port as below:

This is for R1

interface Serial1/0

 ip address 9.9.9.1 255.255.255.0

 encapsulation frame-relay

 serial restart-delay 0

 clock rate 64000

 frame-relay map ip 9.9.9.3 103 broadcast

 frame-relay map ip 9.9.9.2 102 broadcast

This is for R2

interface Serial1/0

 ip address 9.9.9.2 255.255.255.0

 encapsulation frame-relay

 serial restart-delay 0

 clock rate 64000

 frame-relay map ip 9.9.9.1 201 broadcast

 frame-relay map ip 9.9.9.3 201 broadcast

This is for R3

interface Serial1/0

 ip address 9.9.9.3 255.255.255.0

 encapsulation frame-relay

 serial restart-delay 0

 clock rate 64000

 frame-relay map ip 9.9.9.2 301 broadcast

 frame-relay map ip 9.9.9.1 301 broadcast

now, let’s configure the tunnel interfaces. We gonna use the tunnel 0 for all routers. Starting with R1, which will be the hub router for the DMVPN and it’s slightly different from R2 and R3. The commands are

R1(config)#interface tunnel 0

! Firt we need to assign an ip address to the interface !tunnl0

R1(config-if)# ip address 192.168.1.1 255.255.255.0

! second we will specify the source intrerface of this !tunnel, notice that for the hub router we can specify either the physical interface or the ip address, bcz the !ip address is not gonna be changed.

R1(config-if)# tunnel source Serial1/0

! now, let’s enter the ip nhrp parameters

! the following two lines are for the hub only

R1(config-if)# ip nhrp shortcut

! since we use point to multipoint topology, we need to specify that this gre is multipoint

R1(config-if)# tunnel mode gre multipoint

! redirect means that the hub router will inform the !other two router that they can pass traffic between each ! other without passing it through the R1

R1(config-if)# ip nhrp redirect

R1(config-if)# ip nhrp authentication cisco123

R1(config-if)# ip nhrp map multicast dynamic

R1(config-if)# ip nhrp network-id 1

! To specify the MTU size, it is preffered to use the! !value of 1400

R1(config-if)# ip mtu 1400

! The following command prevents the R1 to be always the ! next hop for R2 & R3. Means that the traffic goes to R2 ! from R3 should have R3 as its next hop and vice versa ! ! in eigrp routing table.  

 R1(config-if)# no ip next-hop-self eigrp 1

 ! next we need to disable split horizon feature in case ! we use one of the distance vector protocols

R1(config-if)# no ip split-horizon eigrp 1

! specify the tunnel key. And u should use a strong key ! ! in the real environment. However, for the test lab we ! ! gonna use an easy key. This key must match on all ! ! ! ! routers

R1(config-if)# tunnel key 123

Now we’ve done with the hub router. Let’s move into the other router, and see what is the difference between the hub and the spoke routers

R2(config)# interface Tunnel0

R2(config-if)# ip address 192.168.1.2 255.255.255.0

R2(config-if)# no ip redirects

R2(config-if)# ip mtu 1400

R2(config-if)# ip nhrp authentication cisco123

! nhrp must have the public ip address for the hub router

R2(config-if)# ip nhrp map multicast 9.9.9.1

R2(config-if)# ip nhrp network-id 1

! we need to specify the tunnel ip address for the hub 

! ! router using the keyword nhs = next hop server

R2(config-if)# ip nhrp nhs 192.168.1.1

! also, we need to specify the public ip address for the 

! hub router and map the tunnel ip address to it.

R2(config-if)# ip nhrp map 192.168.1.1 9.9.9.1

! tunnel source in the spoke routers must be the physical 

! interfaces, not the ip addresses. This is bcz the DMVPN 

! is based on the assumption that the spoke router don’t  

! have to have a permanent ip address

R2(config-if)# tunnel source Serial1/0

R2(config-if)# tunnel mode gre multipoint

R2(config-if)# tunnel key 123

! that’s all for R2, and for any other router works as a spoke, all configurations are similar except the !tunnel ip address which must be a unique. 

Disable Strong Passwords Enforcement in windows domain (2008)

Hello,
Today, I will introduce how to allow domain users to use simple passwords. As you know Windows Server by default doesn't allow for a simple password.
Note that this is only for educational purpose. If you intend to apply it for your production environment, make sure that your company's policy allows for that.
To do this you need first to be a member of domain administrators
- Log on to your domain controller
 - Go to Control Panel >> Administrative Tools >> Group Policy Management

- Navigate to Default Domain Policy.Right click and choose edit
- From Computer Configuration > Windows settings > Security > Account Policies

Notice that all passwords and account settings are shown in the right tab
To allow password to be simple, double click on Password must meet complexity requirements
- Change the selected value to Disabled then click OK

- The last step is to update the policy 

Go the the command line and type 

gpupdate /force

That's it!
