Pembuktian Port Forwarding dengan Ngrok

Berawal dari iseng kepikiran sebuah cara untuk melakukan remote terhadap komputer dijaringan kantor. Cara ini dengan menggunakan tunneling untuk melakukan port forwarding ke sebuah PC yang dituju, dengan kondisi saya tidak punya akses ke router, dimana tidak bisa langsung melakukan port forwarding dari router. Namun saya punya sebuah akses ke server dengan melalui SSH.

Dengan akses ini, saya bisa melakukan instalasi aplikasi tunneling bernama Ngrok, dimana ditugaskan utnuk melakukan forwarding ke PC yang saya tuju. Anda diharuskan untuk mendaftar ke Ngrok jika ingin mengikuti langkah ini. 

Instalasi
sudo apt-get install ngrok-client     //install ngrok
    
// authkey adalah key yg anda dapat saat daftar
// 192.168.x.x diisi dengan ip tujuan
// 3389 adalah port tujuan, bisa diganti sesuai port yg anda ingin forwardkan
ngrok -authkey xxxxxxxxxxxxx -proto=tcp 192.168.x.x:3389 

Setelah berjalan, ngrok akan memberikan alamat dengan Port tertentu, contohnya http://ngrok.com:46656. Masukkan alamat tersebut kedalam program remote desktop dan jalankan. Bermodalkan sebuah iPad, tujuan diatas dapat dengan mudah tercapai 😍

Cara ini tidak terbatas hanya untuk remote desktop saja, bisa digunakan untuk Ftp, Smb, dan lain sebagainya tinggal distur melalui portnya. :)

HackRF Mayhem Failed to Update - M0 Guru Meditation Hard

I was on Mayhem Portapack v2.0.1 and want to upgrade to the latest stable release v2.1.0. The update went okay using the web upgrade https://hackrf.app/. But then I saw the latest nightly update and want to try it, since it has many new tools that are not yet included in the stable release. But then the update failed :( Disclaimer: I didn't take any photos of the errors, since I was focused on googling the solution. So the error was " Bad Firmware or Failed W/R error" during the upgrade process, and it was stuck. So I had to restart the device, and it was booting to the Mayhem menu, but on the bottom left, which should show the current firmware version, it was showing a  "FLASH ERR"  message. I think I should go back to the stable release, but I can't. Every time I want to flash the stable release version, the portapack will shows an error M0 Guru Meditation - Hard Fault.  There's an issue that was closed on the Mayhem GIT repo that has the same issue a...

Fiberhome HG6145D2 Superadmin Login

Maybe some of you are using In**ehome ISP as your home internet and found out that using the provided login has minimal options to configure the router: user  user1234 I know it’s not the admin login, and that must be a full-control user account that can be used to control this router fully. So I searched and found some posts on the net and most of them are telling me to use: admin %0|F?H@f!berhO3e I tested it and it doesn’t work! But there’s more to it, you need to reset the router first by pressing the reset button on the side of the router. Then after resetting, you can log in using the admin superaccount! But keep in mind, never use the user log in again, because it will lock the super admin login until you reset the router again. Cheers 🍺

Macintosh Classic II Brightness Issue

The Problem My Macintosh Classic II suffers from an issue where the display CRT goes dim after a few minutes on a cold boot. Every time it happens, I need to crank up the cut-off and brightness  pot behind the machine to show the image. The Analyze At first, I thought it must be the brightness issue, so I searched for the Macintosh Classic analog board schematic to check the brightness line. I found the schematic from Bomarc, and the schematic is suitable with my board, since there are two analog board versions.  I started to suspect the resistors and potentiometer on the brightness line. This Macintosh version has software-controlled brightness, so the analog board will get a 22.25 kHz square wave PBM signal from the logic board to control the brightness. I checked and replaced some resistors and cleaned the potentiometer, but nothing seems to work. The signal is there, and no sign of degradation that makes the screen dim after a few minutes.  Brightness Line So I suspec...
