SMK Negeri 2 North Tambusai (my experience)

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. That is all and thank you.

Damage Laptop and Solutions

December 17, 2015 at 13:45 pm | post by | mumudhi friends, this time I will discuss about damage to my laptop, heheheand I found the solution.
SMK 2 Tambusai NORTH STATEThere are very much damage to the laptop, especially the problem of laptop hardware malfunction. Pretty much difference with the PC that looks much more friendly. In this post I will summarize the problems of the most common laptop hardware and solution respectively. That means that this article is not final and will end when all these issues been discussed.
laptop-cracked-screen2
Problem # 1. Laptop totally dead.Description of the problem: Â When you plug the AC adapter into the laptop, no lights turn on at all. When you press the power button, no reaction occurs. Laptop seems completely dead, no sound, no indication of life.Possible problems:

    
AC adapter fails and the battery is fully discharged. First of all, test the AC adapter. If it dies, replace the adapter.
    
DC jack regardless of the motherboard (or DC jack damaged) and the laptop does not obtain electrical power from the AC adapter. In this case the DC jack should be replaced.
    
Laptop Motherboard damaged. If that happens, most likely unfit laptop repaired.Problem # 2. Laptop turns on but the screen is blank.Description of the problem: the laptop is on, the LED light on the laptop is on, the cooling fan works but nothing appears on the screen. The screen is completely black and empty. No images on the screen at all, even very dim picture does not exist.Possible problems:

    
This problem can be attributed to a failure of memory. Perhaps from the memory module to fail and the laptop does not turn because of it. In this case you can try reseating the memory module to ensure proper contact with the slot. You can try removing memory modules one by one and test the laptop with just one memory module installed. You can try replacing the memory module with the new module.
    
If reseating / replacing the memory module does not help, try to remove the hard drive, DVD drive, modem, wireless card, keyboard, etc ... In other words, loading and attached laptops and only minimal equipment and test again. If the laptop still does not turn, likely failuremotherboard or processor.Problem # 3. Laptop lights up and then die again.Description of the problem:Laptop lit without showing any image on the screen. After a few seconds the laptop will die by itself. Then turns on and off again. This continues to happen until we turn off the laptop completely.Possible problems:Most likely it happened because of some kind of a motherboard failure. You can try reseating / replacing the memory as I described in 2. If the problem does not help, then  damage to the motherboard. In most cases, it is very difficult to replace the motherboard, it is better to buy a new laptop.Problem # 4. Laptops are very noisy.Description of the problem:Laptop is on and everything is working well, he made some peculiarities, namely noise and crackling. Some laptops are making noise at any time, other laptops only intermittently.Possible problems:In most cases this noise coming from the cooling fan or hard drive of the laptop. You can activate the laptop, wait until the voice came again, and then listen carefully to the bottom of the laptop. If the laptop is to make noise when the cooling fan starts running, it is likely damaged. Replace the cooling fan. If the laptop is to make the sound even when the fan is not spinning, maybe it comes from the hard drive. Back up all personal data from the hard drive as soon as possible, the total damage may occur at any time. Replace the hard drive.Here are other techniques to find out whether the noise coming from the fan or hard drive. Remove the hard drive of the laptop and start the laptop. Wait until warm and the fan starts spinning. If the laptop is still making the same sound even when the hard drive is removed, most likely the fan is broken.Problem 5. Laptop die or crash when being used.Problem description:Laptop is up and running properly, but after a while immediately hang or die without any warning. When that happens, the laptop feels hot on the bottom. Also, the cooling fan to work harder than usual.Possible problems:Most likely this is a hot issue processor. This happens because cooling module clogged with dust and the laptop can not "breathe" properly. The laptop is turned off or jammed because of the processor (CPU) is too hot. Clean the cooling fan and heatsink to fix the problem.Problem # 6. Laptop battery is not charged.Description of the problem:Laptop batteries are not charged properly. There are two possibilities; not at all or after you adjust the position of the AC adapter plug in the power connector on the laptop.Possible problems:

    
Damage to the battery. If the battery is completely not filled at all, try using the first battery alone. If it does not help, remove the battery and try running the laptop from the AC adapter only. If the laptop runs fine from the AC adapter but does not charge the battery at all, most likely the battery is damaged or motherboard problem. Try replacing the battery first.
    
Remove the DC power connector. If the battery stops charging once you adjust the position at the end of the AC adapter connector, DC jack means problematic.Problem # 7. The screen went dark while the laptop is running.Ddeskripsi problem:Laptops start correctly, but after a while the screen light off. Image still appears on the screen but is very dark. In some cases the display light never start but you can still see a very faint image on the screen. In all cases the laptop video seems to be fine if you use an external monitor or TV.Possible problems:Most likely it is both the inverter screen or screen backlight lamp (CCFL) is damaged. Both are very similar if damaged and cause a dim screen light. To trobuleshoot types of failures effectively, you need a few parts: a new job or a good inverter backlight lamp is still well known.Problem # 8. Laptops have a strange or chaotic picture on the screen.Description of the problem:Laptop flame correctly but the screen shows a picture of the bad or garbled.Possible problems:

    
Graphics card failure. First of all, test your laptop with an image output on an external monitor. If you see the same problem on the external display, most likely this is the failure of the graphics card.
    
If the problem only appears on the laptop screen, can be associated with one of the following: a bad connection between the video cable and the motherboard or LCD screens or video cable failed or failing LCD screen.Problem # 9. Some laptop keyboard keys stopped working.Description of the problem:Laptop lights up and running properly but some keyboard keys did not work at all or character typo.Possible problems:Most likely some keyboard keys fail. Laptop keyboard can not be repaired. If some keys stopped working, you have to replace the keyboard.Problem # 10. Keyboard keys laptop is lost or damaged.Description of the problem:A missing button on a laptop keyboard.Solution to the problem:If the key is missing from the keyboard, it is still possible to fix it without replacing the entire keyboard. Hopefully you do not damage the hinge button. If you have a lot of lost keys, it may make sense to replace the entire keyboard.Problem # 11. Laptops make repetitive beep sound on startup.Description of the problem:You turn on the laptop but no video on the screen. Instead, the laptop makes a beeping sound repetitive. Laptop will run norman kebali if pressing one of the keyboard keys.Solution to the problem:Most likely it happened because no keys are stuck on the keyboard. In this case you must replace the keyboard.Problem # 12. Liquid spilled on the laptop.Description of the problem:You spill something on your laptop and the laptop stops working.Problem solution:Liquid spills very dangerous and unpredictable. If that happens, turn off the laptop, remove the battery and do not use it until all internal parts inspected from liquid damage.May be useful for friends, so much and thank you :)

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.
