Preliminary
Project that we make is to turn off the computer remotely through a remote ssh and telnet all this is done within the network is connected. This report does not reveal in detail about the basics of networking because it was never made and so many have made is expected that the reader has mastered the techniques of simple networks.
The concept to turn off the computer is very simple things you need is two computers connected through LAN or the Internet and has IP addresses respectively. Furthermore, each computer is given the service telnet or ssh as the active server.
Once connected to turn off the computer is not difficult because it only takes a few simple command lines. Therefore, let us see further how to turn off the computer via ssh or telnet service.
A. System Requirements
1. Operating System that supports networking. In this project we are using Windows XP.
2. 2 network interface card.
3. LAN cable with RJ-45 jack.
4. Using Peer to Peer connection.



B. These steps enable the telnet server:
Basically, every Windows XP already have telnet services but these services are not enabled.
1. Open the Control Panel, select Administration Tools, select Services.
2. Find telnet services open with double click.
3. Turn on telnet service on automatic mode so that when the computer is restarted this service was still active.
4. Because we do not want to restart the activation of the telnet service by typing the start.
C. These steps enable the ssh server:
Linux that we use is a version of debian linux ubuntu on this version of ssh-server is not in the system, therefore, required the installation of this application.
1. Make sure the computer connected to the Internet.
2. sudo apt-get update (to update repisotory)
3. sudo apt-get install openssh-server.
D. Steps to prepare the telnet client.
1. To simply activate windows within windows command prompt.
2. For quite mengaktikan linux terminal via the start menu programs.
E. Steps to prepare the ssh client.
1. To open a linux terminal via the start menu programs.
2. For windows to use additional programs such as putty.
F. Mechanism of action:
The concept to note is:
1. SSH consists of two kinds, the ssh-server and ssh-client.
2. Telnet consists of two types namely telnet and telnet-server-client.
3. Ssh-server can only run on linux based pc.
4. Telnet-server can only run on windows based pc.
5. Basic command of ssh is similar to basic comand on linux terminal.
6. Basic command of telnet similar to the basic command in command prompt windows.
7. Ssh-client to run on Linux is by using the terminal from linux itself.
8. Ssh-client to run on Windows by using an additional program putty.
9. Telnet-client to run on Linux is by using the terminal from linux itself.
10. Telnet-client to run on windows by using the command prompt from windows itself.
G. Turning off the computer through ssh service.
On the concept is as follows
Computers 1> Computer 2
Ssh-ssh client-server
Computer 1 will try to turn off the computer 2 therefore follows several principles:
1. Ssh-client can be either windows or linux.
2. Ssh-server can only run on Linux.
Step through linux terminal:
1. Open a linux terminal.
2. Enter ssh user_name @ ip_address
3. Enter password
4. Type sudo shutdown-h now

Explanation:
1. user_name is the user name that is used on Linux computers to be turned off
2. ip_address is ip address that is used on Linux computers to be turned off.
3. sudo declare ourselves as root or administrator is entitled.
4. -H states to shut down the whole system.
5. now claimed to turn off when the command was diexecute.

H. Turn off the computer via the telnet service.
On the concept is as follows.
Computers 1> Computer 2
Telnet-Telnet client-server.
Computer 1 will try to turn off the computer because it follows several principles:
1. Telnet-client can be either windows or linux.
2. Telnet-server can only run on windows.
3. Step through the command prompt windows.
4. Open a terminal windows.
5. Enter telnet ip_address;
6. Enter a password.
7. Type shutdown-s

Explanation:
1. user_name is the user name is in use in the computer 2 or Windows computer to be turned off.
2. Ip_address is the ip address of the computer that will be turned off.
3. -S states to turn off the computer now.
CHAPTER III - Closing
Conclusion
1. Turning off the computer through the remote is not difficult. The computer will shut down in this concept must be based ipaddress because telnet and ssh will only work through the ipaddress should be the respective sets of computers.
2. telnet through ssh through their respective ports 23 and 22.
3. Firewalls can turn off each destination port 23 and 22 so it is suggested you turn off all firewalls are active.
4. Every computer that terkoneksikan into the Internet network can be turned off via the remote by pointing ssh and telnet to the ip address that in this case configured in the ip address should be a public ip address not the internal ip address.
5. Connection via the Internet can harm your network it is advisable not to pass up the remote via remote let alone do it with telnet get yourself to do it is rarely possible and not on a public computer. If you would often do so you can use a network that is private, such as VPN.
6. Not all computers that have public ip_address can be connected via telnet and ssh because of the number of routers that are secure by not allowing connection with a specific port.
Suggestion
1. to install applications via apt-get included in linux you can use local repisotory like vlsm.org do customization through the / etc / apt / sources.list
2. Linux ubuntu can not detect any hardware modem telephone therefore advised to check compatibility via the live cd first.
3. Linux installation can make you lose your windows look carefully selected for your partitions mencustomize avoid unnecessary formatting.

GOOD TRY ...........
