http://smkn2tambusaiutara.blogspot.co.id/
Experience of studying in SMK Negeri 2 North Tambusai Department of Computer Engineering and Networks (TKJ) -bercerita about life experience does not exist exhausted her. This time I told him about the experience of her first day at SMK Negeri 2 North Tambusai, Tambusai north, Kab. Rokan Hulu.
SIGN FIRST DAY EXPERIENCE SMK ...
Friends Hy friends, my name kenalin Mudin, I live in Mahato precisely on Jl. New, wekwekwek. , , : D !!
I am beginning to register in vocational began in 2012 in June. I chose a school "SMK 2 Tambusai North" because I feel interested and comfortable with the state and the school. Initially SMK is private and the process of teaching and learning was in the building SMP Negeri 3 Tambusai north, due to the construction of vocational schools (SMK) has not been completed, started or study while still in school building land 3 Tambusai north at 1 PM to 5 PM after that return. Is an unforgettable experience at the time along with the productive teacher Heri Susanto S.Kom father, at that time I was told to the future for uninstalling the program, and I was still timid first advised hehehe holding laptop, let alone uninstall a program, I do not dare to move the cursor I did not dare, wekwekwek and I along with my friend was sentenced to tweak each of our ears, that's an unforgettable experience. And day after day, time after time I go through, do not feel the Year 2013 in January is finally building was already completed vocational 4 while still building, and we were moved to a new building, hehehe  tu strategic place and SMK had two field .. Field volleyball and one badminton court (in front of the school), wkwkwk ...: D at SMK Negeri 2 Tambusai North, has a canteen 2 ,, learning atmosphere here is also quiet and comfortable.

    
Initially I hesitated list at SMK Negeri 2 North Tambusai, because her students are still some people, and his school was still private. And after I entered the first day, the first time I study Computer Engineering & networks, I think learning TKJ was difficult and it was fun TKJ.

    
After a few years later we SMK was inaugurated in 2013, namely SMK Negeri 2 Tambusai North, and her show was very enjoyable. Our school was known to many people.

 
Well, it was the story of my first experience entering SMK. So and terimkasih.

COMPUTER AND NETWORK ENGINEERING

COMPUTER ENGINEERING AND NETWORKING - What's up buddy TKJ, time I will discuss about Debian Basic commands. In the Debian Linux distribution there are a lot of commands to perform a job. The basic commands that must be mastered so that we can carry out the work. We as a beginner is better to know and never use the minimum basic commands it because someday the commands it will be useful to us as a beginner Linux users

Here we will learn about 27 basic commands in linux debian. Friend number 27 commands that we will learn is not the sum of all existing orders in the Debian Linux distribution, but it is all only partially. In this modern world especially for the development of technology will surely grow, as well as the basic commands that will we learn this will inevitably increase as well. Here are the basic commands Linux Debian:

    
1. any_command -help: displays help about the basic commands of linux debian.

    

    
2. Ls: serves to display the current directory. So if we get too many open a directory, we only need to type the command "ls" which followed the name of the directory that you want to open the terminal root program. It will appear on the screen itself.

    

    
3. ls -al: the same as the command "ls" only command "ls -al" displays all active directory one by one on the screen.

    

    
4. Cd: which stands for change directory that serves to change the directory using the cd.

    

    
5. Cp: the same as the function of the Ctrl + c on Windows is to copy a file.

    

    
6. mcopy: This command is used to rename a file and also move a file.

    

    
7. rm: which stands remove files that serves to remove a file or files.

    

    
8. mkdir: function to create a new directory, kepajangan of this command is make directory.

    

    
9. rm: together with the rm command that removes files, only files rm remove a file while rm directory to delete a directory.

    

    
10. rm -r command, which stands for recursive remove that serves to delete a file, directory, or subdirectory. We need to know to be careful using this command because this command can delete all the data on the system, and in Linux there is no undelete command.

    

    
11. more: the more orders we can see the contents of a file, and the file contents can be displayed screen by screen.

    

    
12. Less filename: bergunamenampilkan a file screen by screen. If we want to stop this command just press the button "p" will stop.

    

    
13. pico filename: This command is used to edit a text file.

    

    
14. pico -w filename: the same as the command "pico filename" is editing a text file. Only in this order accompanied by mengnokatifkan word warp function. And this command is useful for editing text files such as / etc / fstab.

    

    
15. lynx file.html: This command serves notice an html file with a text mode. This command is one way to open a browser and also appropriate to search for articles without the image.

    

    
16. -zxvf tar filename.tar.gz: This command is used to extract the tar file as well mengun-compres the tar file.

    

    
17. tar -xvf filename.tar: same as "tar -zxvf filename.tar.gz" which serves to extract a tar file but there is this command is extract the tar file is decompressed.

Troubleshooting Network Problems

Troubleshooting Network Problems

Troubleshooting Network Problemsby Mudin · June 7, 2009By Ki GrinsingForewordArguably the most of your home does not have the tools or tools to troubleshoot network problems such as LAN tester, Multi-meter or the like. We know that our computer network is not always going to go according to our expectations to be at his best. Once there are times when we experience a network problem that requires us to look for troubleshooting the problem and restore the network as normal.Troubleshooting toolIf in a complex enterprise-class network, a network engineer or some use tools to troubleshoot network problems eg with network management tools for detecting points of damage, LAN-tester, multi-meter etc. As for the network dirumahan you do not need or none of these tools to fix your network problems.Diagram network conceptFigure 1 below shows the LAN network diagram dirumahan used to share an Internet connection such as Speedy or other Cable networks where the network device that is commonly used is a modem-router connected to the Internet through your ISP, a LAN switch, connecting a network cable between modem- router with Switch, and multiple computers. PC-A is connected to Switch (port # 1) by using a network cable and PC -A-B-B network cable to a switch port # 7.In fact, as the above diagram is not exactly raw, but most devices in the market that combines the functions of a modem and router into one device. At Speedy network is usually much use wireless ADSL gateway call TP-link TD-W8960 or the like which also has an Ethernet port to the computer amounted to 4 either 100Mbps or Gigabit. In addition it also provides a wifi connection over the airwaves that could connect a laptop with wifi adapters, and some types of smartphones or tablet computer both based on Android, Blackberry, iOS (Apple phone) or Windows phone.Several kinds of network problemsThere are some situations where you have internet connection problem that requires you perform network troubleshooting.A> PC-A can not access the internet but PC-B canIn this scenario, the PC-A disorder can not connect to the internet, while the PC-B is not problematic at all. It can be summed up as follows:

    
Internet services from ISPs no interference
    
The possibility of switch or port is problematic
    
Modem is not problematicTroubleshooting network problems that you can do is suspect there is a problem in the computer's NIC adapters, port Switch problematic, or the network cable-A problematic.a. NIC disabledMake sure that the NIC adapters PC-A you are not disabled accidentally. You can see signs of local connection icon (the computer image twins) bottom right corner of your screen. If normally you can see it now you do not see it, you should suspect if your NIC adapters in the disabled condition. In XP / 7 Go to Control Panel: Click Start> Control Panel> double-click the network connection> see if there are any local connection icon in the adapter you disable condition commonly characterized by a faint gray color as in figure 2 below.Figure 2 - Local connection icon and NIC adapter disabledIf it looks faintly gray, right-click the icon and select Enable. If successful, then you can see again the computer image icon bottom right corner of your monitor.Use the "ipconfig / all"You can also perform testing using the command 'ipconfig / all' on the command line. Go to the command line interface by pressing the 'picture windows' and the 'R' simultaneously and the Run Command type cmd and press Enter. Or you can use click Start> select Run> type 'cmd' and press Enter. At the command interface type:Ipconfig / all <press Enter>Then will come a series of configurations such as the following message:Windows IP ConfigurationHost Name. , , , , , , , , , , , : TOWERPrimary Dns Suffix. , , , , , , :Node Type. , , , , , , , , , , , : UnknownIP Routing Enabled. , , , , , , , : NoWINS Proxy Enabled. , , , , , , , : NoInternal Ethernet LAN adapter:Connection-specific DNS Suffix. :Description. , , , , , , , , , , : Realtek RTL8139 Family PCI Fast Ethernet NIC # 2Physical Address. , , , , , , , , : 00-1C-F0-F2-B9-A9Dhcp Enabled. , , , , , , , , , , : NoIP Address. , , , , , , , , , , , : 192.168.1.25Subnet Mask. , , , , , , , , , , : 255.255.255.0Default Gateway. , , , , , , , , : 192.168.1.1DNS Servers. , , , , , , , , , , : 202.134.1.10Use the "ping localhost"Or you can also use testing using command 'ping localhost' or 'ping 127.0.0.1' which serves to ensure the TCP / IP configuration you perfectly, see if you get a good response. If you get a RTO (request time out) then we can be sure that the TCP / IP configuration you are not correct or your NIC adapters in the disabled condition.b. Switch Port ProblemsPC-A does not have access to the internet could be because the port that is connected to the PC-A problematic presumed dead. In general, a switch is equipped with LED lights that represent each port. If the port is active / connected to a computer which again On, the lamp will light blinks rapidly alias.Check the network cable-A leads to what port number (in this case the port # 1) and see if the port # 1 LED lights blink fast or die. If you find the lights off, try to first remove and insert again strongly in both PC-A and also at the switch and see if there is a response. If still dead, then move the network cable-A to port empty eg port # 2 and see if there is a response. If the port # 2 turned out to be alive and PC-A can connect to the internet, then you can be sure the port # 1 is damaged. Mark the port # 1 is the sign 'tusak' or cover it with insulation.c. Cable Network ProblemsIf in step b above you do not succeed, then the next step is to make sure that the cable is in trouble. Swap-A cable with a network cable from the computer B-B and see if there is a reaction with LED Flash and PC-A can connect to the internet. If it can resolve the issue then you can ensure that the network cable-A problematic. Mark the cable with a 'broken' and replace it with a new one.B> All PCs can not Connect to the InternetIf you find that all the PC can not connect to the internet, chances are you have a problem:

    
With Switch you, or
    
With a modem-router, or
    
The connection cable between the switch and the modem, or
    
The problem lies with your ISP.If you find all the switch is off, make sure the power is installed properly, and if you still do not want to On, then you can be sure there is a problem with your Swicth. Replace with a new one or take it to the electronic workshop.If the lamp power and all ports are active (port # 1 and port # 7 in this scenario) turns On, then try to make sure the network cable connection between the modem-router Swicth well connected. Remove and reinsert the cable ends on both sides in the Switch and on the modem and see if there is a change. If it turns out to be back to normal internet connection, the connection your connection is not perfect.If the connection you can ensure a good connection, then try to replace the cable and see what resolve the problem or not. If successful, it means that the cable is problematic, marked by a 'broken'.If it turns out the problem persists, then you can call your ISP provider if there is a problem with the internet service.Stages troubleshooting network problems is commonly used for dirumahan although the concept can be applied in business class and enterprise network great.By Mudin
Troubleshooting DHCP Server pada Debian

Troubleshooting DHCP Server pada Debian

Troubleshooting DHCP Server pada Debian

Pada saat Menginstall dan Konfigurasi Paket debian pasti sering mengalami masalah termasuk DHCP-SERVER maka itu Rumah Wacana akan membagikan Cara Mengatasi Masalah DHCP Server Pada Debian berikut penjelasannya.

1.kesalahan dalam Memasukkan IP server DHCP server

Kasus ini cukup sering ditemui dalam jaringan dengan server DHCP. Misalnya, apabila rentang alamat IP yang ditentukan dalam konfigurasi server DHCP adalah dari 192.168.1.1 hingga 192.168.1.100, maka setiap komputer klien yang terhubung ke jaringan ini akan mendapatkan IP secara otomatis dalam rentang tersebut. Namun, ada suatu saat satu atau dua komputer yang mendapati IP yang berbeda seperti 169.254.X.X setelah melihat konfigurasi IP nya melalui ipconfig, untuk windows, atau ifconfig, untuk klien Linux. inilah yang sering terjadi pada saat melakukan instalasi DHCP-server.

Cara Mengatasinya :

Apabila dalam satu jaringan jika ada komputer klien yang mendapati IP berbeda dari rentang alamat DHCP, maka dapat dipastikan bahwa pemberian alamat tersebut bukan berasal dari server DHCP. Alamat tersebut diberikan oleh layanan APIPA (Automatic Private IP Addressing) di komputer klien.
Ada dua kemungkinan permasalahan yakni pada komputer client dan pada server DHCP itu sendiri. bisa dikatakan permasalahan dalam kabel yang digunakan untuk terhubung ke jaringan.

2. PERMASALAHAN UMUM DHCP-SERVER

Apabila hampir semua komputer klien kesulitan untuk mendapat alamat IP, boleh jadi permasalahan ada pada server DHCP. Apabila demikian perbaikannya dapat dimulai dengan melakukan tes status koneksi server DHCP ke jaringan menggunakan ping. Pastikan terlebih dahulu kalau alamat IP server DHCP sesuai dengan subnet yang digunakan saat ini, misalnya jika subnet yang digunakan saat ini adalah 192.168.1.1/24 maka alamat IP server seharusnya berada pada rentang IP dari 192.168.1.100 hingga 192.168.0.254.Selain itu pastikan konfigurasi server DHCP telah sesuai terutama pada rentang alamat IP yang disewakan ke klien. Rentangnya juga harus berada pada subnet yang sama di jaringan tersebut.

3. DUPLIKASI (KONFLIK) ALAMAT IP KLIEN

Walaupun langka namun kejadian juga dapat terjadi, dimana ada lebih dari satu komputer memiliki alamat IP yang sama dalam satu jaringan. Kondisi ini dapat terjadi karena adanya klien yang menggunakan alamat statis dan dapat juga karena keberadaan server DHCP lain yang memiliki rentang alamat IP saling beririsan.
Mungkin penjelasan ini dapat membuat anda lebih memahami permasalahan dalam DHCP-SERVER dan membuat anda lebih semangat belajar Debian. Troubleshooting DHCP server pada Debian ini harap benar-benar di perhatikan dengan baik-baik. Sebab konfigurasi DHCP akan memiliki permasalahan yang paling banyak terjadi.
