Membuat Bootable UFD Installer (Multi) OS Bagian ke-2: Ventoy

Biasanya satu image ISO / OS hanya bisa ditulis ke satu UFD. Bagaimana kalau kita mau image-image tersebut dalam satu UFD sekaligus? Ada artikel yang pernah dipublish penulis  di tahun 2018, 'Creating Bootable USB OS Installer' yang membahas aplikasi multisystem. Kali ini penulis akan membahas aplikasi sejenis yaitu Ventoy:

Ventoy

Berikut caranya:

1. Download Aplikasinya & ekstrak dalam folder pilihan anda
2. Jalankan  aplikasinya, 
1. gunakan ini di terminal dalam folder aplikasinya:
   $sudo ./VentoyGUI.x86_64
2. Pilih USB flashdisk  (UFD) yang akan digunakan Multi ISO Installer
3. Pilih tipe partisi. MBR untuk PC yang hanya memakai BIOS  (Non UEFI), GPT untuk PC baru)
4. Pilih Install
   
   
   
   
   
3. Aplikasi akan membuat 2 partisi/volume di UFD Anda, pertama untuk boot (VTOYEFI), ke-2 untuk menyimpan image OS (Ventoy).
   
4. Copy image OS Anda (*.iso) ke Partisi ke-2 (Ventoy)
   
5. Boot ke USB

Anda dapat menempatkan file ISO sebanyak mungkin di partisi ke-2 karena prosesnya cuma cut/copy & paste sederhana, tidak perlu konfigurasi lebih lanjut.

ISO Image yang penulis uji:

1. Image / Installer OS Linux: Linux Mint, Linux Mint LMDE, Ubuntu, POP_OS!, Manjaro & Chimera OS. Tentunya akan bisa berfungsi dengan image / installer OS Linux lainnya di luar sana.
   
2. Image / Installer OS Windows: Windows 7 / 8.1 / 10. Tiny10 (Windows 10 Enterprise LTSC minimal)  adalah pengecualian, dia lebih berfungsi sebagai image tunggal (Anda bisa menggunakan multisystem atau balenaEtcher untuk menulis ISO ke UFD)
   
3. ISO Utilitas: Parted Magic, UBCD, UBCD Live. Beberapa utilitas seperti G4L (HDD Cloning) dan ISO Antivirus populer, menolak untuk boot

Creating Bootable UFD (Multi) OS Installer Part 2: Ventoy

Usually one ISO (OS) image can only be written to one UFD. What if we want these images in one UFD at once? There is an article published by the author in 2018, 'Creating Bootable USB OS Installer' which discussed application called multisystem. This time the author will discuss similar application, Ventoy

Ventoy

Here's how:

1. Download the App & extract it in your preferred folder
2. Run the app, 
1. use this on terminal inside the extracted app folder:
   $sudo ./VentoyGUI.x86_64
2. Choose the USB flashdisk  (UFD) to be used for Multi ISO Boot. 
3. Choose the partition type (MBR for older/BIOS only PC & GPT for newer)
4. click Install
   
   
   
   
   
3. It will then create 2 partitions/volumes in your UFD, 1st for boot (VTOYEFI), 2nd for OS images space (Ventoy).
   
4. Copy your OS images (*.iso) to 2nd Partition  (Ventoy)
5. Boot to USB

You may put as many ISO in the 2nd partition as the process is a simple copy/cut & paste, no need further configuration.

Tested with:

1. Linux OS images / installer: Linux Mint, Linux Mint LMDE, Ubuntu, POP_OS!, Manjaro & Chimera OS. Surely it will work with any other Linux OS images / installer out there.
2. Windows OS images / installer: Windows 7 / 8.1 / 10. Tiny10 (Custom to Minimal / Trimmed Windows 10 Enterprise LTSC) was the exception, it rather work alone (you might want to use multisystern or balenaEtcher to write the image to UFD)
3. Utilities ISO: Parted Magic, UBCD, UBCD Live. Again, some utility like G4L (HDD Cloning) and popular Antivirus ISO, refused to boot

Creating Bootable UFD OS Installer Part 1: balenaEtcher

As computer enthusiast, we really want to try various computer OS for various reasons, whether we want to upgrade, are bored, disappointed, or are looking for new challenges. On the internet there are many computer OS images that can be downloaded, write to CD/UFD and to try them immediately (Live CD/UFD for various Linux distributions) or just as an installation media (MacOS & Windows). 

On Linux apart from internal utility from the OS such as USB Image Writer from Linux Mint, there are few applications to help you write OS images such as balenaEtcher and Ventoy

balenaEtcher

balenaEtcher or simply Etcher Is a single ISO image flasher/writer application to UFD AND ALSO TO MEMORY CARDS for Linux/MacOS/Windows. This application is an alternative to the Rufus utility on Windows which functions more or less the same.

Here's How:

1. Download the app & extract it in your preferred folder
2. use this on terminal inside the extracted app folder:
   $sudo chmod 777 *.AppImage
3. Run the AppImage file 
1. eg. $./balenaEtcher-1.7.9-x64.AppImage 
   
2. Select Image to write, device to write on to, flash!
3. You can now boot the UFD

Membuat Bootable UFD Installer OS Bagian ke-1: balenaEtcher

Sebagai pengguna antusias komputer, kita sangat ingin mencoba berbagai OS komputer karena berbagai alasan, entah ingin mengupgrade, bosan, kecewa, atau sedang mencari tantangan baru. Di internet banyak sekali image OS komputer yang bisa didownload, ditulis ke CD/UFD dan langsung dicoba (Live CD/UFD untuk berbagai distro Linux) atau hanya sebagai media instalasi (MacOS & Windows).

Di Linux selain aplikasi internal dari OS seperti USB Image Writer dari Linux Mint, ada beberapa aplikasi untuk membantu Anda menulis image OS seperti balenaEtcher dan Ventoy 

balenaEtcher

balenaEtcher atau Etcher adalah aplikasi flasher/penulis image OS tunggal ke UFD DAN JUGA KE KARTU MEMORY untuk Linux/MacOS/Windows. Aplikasi ini adalah alternatif dari utility Rufus di Windows yang fungsinya kurang lebih sama.

Berikut Caranya:

1. Download aplikasinya & ekstrak di folder pilihan Anda
2. gunakan ini di terminal di dalam folder aplikasi yang diekstraksi:
   $sudo chmod 777 *.AppImage
3. Jalankan fils AppImage 
1. contoh: $./balenaEtcher-1.7.9-x64.AppImage 
   
2. Pilih Image untuk ditulis, perangkat yang akan ditulis, flash!
   
3. Boot ke UFD

Bagian ke-2...

Mid-2022!

 Now I have the time to post few things to my blog. Hope this would help me to recollect these things later on

<bahasa indonesia>
Sekarang saya punya waktu untuk mem-posting beberapa hal ke blog saya. Semoga ini bisa membantu saya untuk mengingat hal-hal ini nantinya

Mematikan Windows Fast-Start HDD Lock dari Linux

 Jika Anda melakukan dual-boot Linux Anda dengan Windows 8.x / 10 (biasanya untuk gaming), Anda mungkin mengalami bahwa Anda tidak dapat menulis atau memuat/mount drive NTFS Anda (baik yang digunakan sebagai sistem atau data saja). Ini biasanya disebabkan oleh Windows Fast-Start HDD Lock

Solusi Umumnya adalah Nonaktifkan Windows Fast-Start dari Windows. Ini mengharuskan Anda untuk boot ke Windows, nonaktifkan fast-start dari Settings - Power Option - Choose what the power buttons do - Change settings that are currently unavailable - Shutdown settings - hilangkan centang Turn on fast startup - full shutdown Windows - reboot ke Linux

Jika gagal maka Anda dapat memaksa untuk Mematikan Windows Fast-Start HDD Lock dari Linux anda.Ada perintah ntfsfix (bagian dari paket ntfs-3g), yang memperbaiki beberapa inkonsistensi NTFS, mengatur ulang file jurnal NTFS dan menjadwalkan a Pemeriksaan konsistensi NTFS untuk boot pertama ke Windows. Ini mungkin dapat merusak instalasi Windows Anda, jadi tidak disarankan untuk drive sistem

Namun ini dapat berguna dalam beberapa kasus.Misalnya, jika Anda tidak lagi menginstal Windows 10 atau 8, tetapi partisi NTFS dibiarkan dalam keadaan hibernasi (Terkunci).Dalam kasus tersebut, Anda dapat menggunakan:

sudo ntfsfix /dev/<NTFS_partition> (misalnya /dev/sdb1)

untuk membuat partisi dipasang dengan akses baca/tulis penuh.

How to Manually Turn-Off Windows Fast-Start HDD Lock from Linux

If you dual-boot your Linux with Windows 8.x/10 (usually for gaming), you may experienced that you cannot write or possibly your NTFS drive whether they used as system or data only. This usually caused by Windows Fast-Start HDD Lock 

Current solution is to Disable Windows Fast-Start from within Windows. It requires you to boot to Windows, turn-off the fast-start from Settings - Power Option - Choose what the power buttons do - Change settings that are currently unavailable - Shutdown settings - uncheck the Turn on fast startup - full shutdown Windows - reboot to Linux

Should it failed then you can force to Turn-Off Windows Fast-Start HDD Lock  from your Linux. There is the ntfsfix command (part of the ntfs-3g package), which repairs some NTFS inconsistencies, resets the NTFS journal file and schedules a NTFS consistency check for the first boot into Windows. This might corrupt your Windows installation though, so it's not recommended for system drive

However it can be useful in some cases. For example, if you're no longer have Windows 10 or 8 installed, but a NTFS partition was left in a hibernated state (Locked). In such cases, you could use: 

sudo ntfsfix /dev/<NTFS_partition> (for example /dev/sdb1) 

to get the partition to mount with full read/write access.

Game DRM-Free

Apa itu Game DRM-Free? English version

Untuk tahu lebih jauh berikut definisi DRM menurut Wikipedia:

Peralatan Manajemen Hak digital (Digital Rights Management (DRM) adalah seperangkat teknologi kontrol akses untuk membatasi penggunaan perangkat keras berpemilik dan karya hak cipta.Teknologi DRM mencoba mengontrol penggunaan, modifikasi, dan distribusi karya berhak cipta (seperti perangkat lunak dan konten multimedia), serta sistem di dalam perangkat yang menerapkan kebijakan ini.

Pada dunia game di PC atau PC Game, DRM sering disebut sebagai copy-protection. Ada bermacam-macam copy protection yang ada sejak era PC Game dimulai (1980an),  

• proteksi fisik media (laser hole atau hidden file/sector pada floppy disk atau CDROM),  
• proteksi yang mengacu ke buku petunjuk/manual (misalnya 'masukkan kata dari halaman (x) paragraf (y) dan kata ke-(z)')
• proteksi serial number unik (seperti Windows 95/98)
• proteksi one-time online/phone registration (seperti Windows 7 ke atas)
• proteksi periodik/selalu online (seperti DVD game dengan sistem Denuvo)
• proteksi melalui client ekosistem gaming (Steam/Epic/Uplay/Origin)

Game DRM-Free secara bebas diterjemahkan sebagai game yang dijual tanpa menggunakan DRM atau copy protection. Dipopulerkan oleh perusahaan distributor game GOG.com, DRM-Free Game adalah sebuah konsep bahwa game harus bisa dimiliki secara fisik tanpa harus tergantung pada pihak distributor (kecuali waktu mendownloadnya), sehingga bisa dipindah (diinstall/dicopy) sesukanya selama kita memang sudah memiliki hak atas game tersebut. DRM-Free Game adalah anti-tesis dari kebutuhan bahwa game harus diproteksi untuk memastikan hak ciptanya terjaga. 

Tidak seperti game dengan DRM yang terasa seperti kita memiliki hak guna pakai/sewa (kecuali kita punya media fisik dan tidak butuh online untuk menggunakannya), DRM-Free membuat kita seperti memiliki hak milik

Lebih lanjut, ternyata pada ekosistem gaming seperti Steam, Epic, Uplay, Origin, dan Bethesda tenyata 'diselundupkan' game-game DRM-Free karena sebagian pengembang game merasa tidak perlu menambahkan DRM untuk game mereka

DRM-Free Games

What are DRM-Free Games?

To find out more, the following is the definition of DRM according to Wikipedia:

Digital rights management (DRM) tools or technological protection measures (TPM) are a set of access control technologies for restricting the use of proprietary hardware and copyrighted works. DRM technologies try to control the use, modification, and distribution of copyrighted works (such as software and multimedia content), as well as systems within devices that enforce these policies.

In the world of PC games, DRM is often referred to as copy-protection. There are various copy protection that have existed since the PC Game era began (1980s),

• physical media protection (laser hole or hidden file / sector on a floppy disk or CDROM),
• protection that refers to the manual / manual (for example 'insert word from page (x) paragraph (y) and word (z)')
• unique serial number protection (such as Windows 95/98)
• one-time online / phone registration protection (such as Windows 7 and above)
• periodic / always online protection (such as DVD games with Denuvo systems)
• protection via the gaming ecosystem client (Steam / Epic / Uplay / Origin)

DRM-Free Games is freely translated as games that are sold without the use of DRM or copy protection. Popularized by game distributor company GOG.com, DRM-Free Game is a concept that games should be physically owned without having to depend on the distributor (except when downloading them), so they can be moved (installed / copied) at will as long as we already have the rights. over these games. DRM-Free Game is the anti-thesis of the need that games must be protected to ensure that they are copyright protected.

Unlike games with DRM, which feel like we have lease rights (unless we have physical media and don't need to be online to use it), DRM-Free makes us feel like we have ownership rights.

Furthermore, it turns out that in gaming ecosystems such as Steam, Epic, Uplay and Origin, there are DRM-Free games smuggled-in because some game developers feel that they don't need to add DRM to their games.

Creating Bootable USB OS Installer

This is an old stuff but I decided to write this as this is one of indispensable  utility for me for a long time.
It allows you to have multiple OS installer in an USB flashdisk. Although you can have several Android and Linux installer in one flashdisk, it only allowed 1 version of Windows.
The official site:
https://sourceforge.net/projects/multisystem/

Watch out with the language, since this app is originally French, but overall is very good.

For easier method of install (Ubuntu derived / PPA) you can use:
$ sudo apt-add-repository 'deb http://liveusb.info/multisystem/depot all main' 
$ wget -q -O - http://liveusb.info/multisystem/depot/multisystem.asc | sudo apt-key add - 
$ sudo apt-get update
$ sudo apt-get install multisystem

Compressing PDF File using (ghost)script

Dealing with Big PDF File can be pain in the a** especially when using slow internet connection or limited space on server.
Thus I've come across script on make things easier. Here's the script:
$ ghostscript -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf

You can get more explanation at:

Access Microsoft Onedrive in Linux

Onedrive is a personal cloud storage from Microsoft (similar to Google Drive or Dropbox). It gave you fair amount of space to put your (un)important stuff on-line and have your mobile device access it later on.
Based on these instructions I'm able to connect to Microsoft Onedrive from Linux Mint 17 using onedrive-d . I use them with slight modifications as follow,

1. The first step to installing onedrive-d is to open a terminal window and clone the source code from git using the following command:
   git clone https://github.com/xybu92/onedrive-d.git
   
2. If you don’t have “git” installed, you can install it with the command:
   sudo apt-get install git
3. Now change directory into the onedrive-d folder:
   cd onedrive-d
4. Run the installation script:
   sudo ./install.sh
   
5. After installation you should run:
   sudo onedrive-pref
6. Answer with default values. In the end you have ~/OneDrive folder (at your home folder)
7. To activate run:
   sudo onedrive-d start

Now you can access Onedrive as your local folder

A Reason to Move

Not Into Linux Yet? Gaming hold you back? Here's a reason to move to Linux,

Humble Indie Bundle 14

www.humblebundle.com

The Humble Indie Bundle is back with 7 cross-platform games available DRM-free and on Steam!

Oh, did I tell you before for other reasons? Here's a few other:

• The OS is free
• Relatively secure, virus-free compared to W*****s. You can read this for reference
• You're tired of hard disk defrags,  antivirus updates, wait (ages) while OS updates, always need restarting for stabilty
• Came with essential apps (internet, office), free
• Games are staying strong (Steam.com, GOG.com, Humblebundle.com)
• Hunger for new challenges or fulfilling any curiosity on computing
• or any of you can add more to the list?

Change of Name

Changed my blog name to reflect more of the content. I don't play that much though, but still am.

Internet Connection Sharing on Linux Mint 17.1

I've read,  tried and failed several times on this. At first I thought it might be a snap using howtos tutorials scatter around internet. But it turn out to be no general solution to this. The keywords are gateway, ip masquarade, and off course, Internet Connection Sharing on Linux.

Here's a working solution that works using Linux Mint 17.1 and these configuration/setup

1. You have cable/ADSL internet connection that need to be shared to a closed network at home/office.  
2. A small server with 2 network cards, one connected to the cable/ADSL router/modem and one to the home/office network
3. Have a working connection from server that you can connect to router/modem in one connection and internal network for another (you can use ping to their addresses respectively)  
4. Here's my sample of ifconfig result from the server:

On the server

1. Create a script as adminitrator called ishare

$ sudo vi /usr/local/bin/ishare
   
   The WAN interface (eth0) can be replaced according to your network interface (should be the one connected to the internet)
   
   
   #!/bin/bash
   ## Internet connection sharing script
   sysctl -w net.ipv4.ip_forward=1
   sysctl -p
   iptables -X
   iptables -F
   iptables -t nat -X
   iptables -t nat -F
   iptables -I INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
   iptables -I FORWARD  -m state --state RELATED,ESTABLISHED -j ACCEPT
   iptables -t nat -I POSTROUTING -o eth0 -j MASQUERADE
   
   
2. Save the above script to /usr/local/bin/ishare, and then change the executable bit by the following command.
   
   $ sudo chmod +x /usr/local/bin/ishare
   
   
If you want the script executed every startup, you can register the script to /etc/rc.local.
Open /etc/rc.local, before statement "exit 0", add the following line:

/usr/local/bin/ishare 

Had a few notes on etc/sysctl.conf , whether to set the net.ipv4.ip_forward=1
manually or the script will handle it. I'll update it after I retest it (I'm also planning on test it on Zentyal server).

For  the client you have to connect to internal network using the same segment and set the ip manually within the ip range
e.g in my case, this is the setup

ip: 10.0.1.20
subnet: 255.255.255.0
gateway: 10.0.1.2 #using servers internal ip address
dns: 8.8.8.8 #using google dns

Be sure to check the original reference if you stumbled upon troubles. Also, I haven't include any advanced rules on firewall settings to it so be advised.
