Review Partisi Reiserf Linux

Posted by aribowo21 on January 29, 2009

beberapa review dari forum :
- Lebih kencang dari ext2 dan ext3. Belum pernah rusak karena shutdown tidak wajar. Dua unit desktop, satu unit laptop.
- Kalau tidak salah ingat keduanya pernah menunjukkan tanda-tanda setelah shutdown tidak wajar. Saya sudah lupa detilnya.
- Katanya sih reiserfs lebih cepet untuk I/O ke harddisknya tapi belum

- Di laptop si ext 3 biar bisa dibaca dari windows n mac. kompi di rumah, root nya pake XFS. tp berhubung grub gak bisa baca XFS, /boot jadi pake ext3 aja. si mbek jg dipasangin XFS semua (err.. kecuali di hdd lama).
- kadang ketika jalanin livecd utk benerin partisi suka kecewa ketika mengetahui livecd itu tidak mendukung filesystem selain ext2/ext3.

Partisi dasar linux secara umum

Posted by aribowo21 on January 29, 2009

Partisi adalah space/ruang dalam hardisk yang dibagi-bagi dengan kapasitas tertentu dengan file system tertentu. Partisi adalah bagian yang amat esensial dalam GNU/Linux. Secara minimal, Linux hanya memerlukan dua partisi saja. Partisi Swap dan root (/). Secara verbose (rinci), anda bisa saja membuat lebih dari dua partisi untuk GNU/Linux. Misalnya, partisi khusus untuk direktori /boot, /home, /usr, /bin, /var, /etc atau partisi tambahan lainnya. Tapi, bagi pemula seperti saya, cukup membagi-nya menjadi 3 partisi saja. Partisi swap (2x RAM komputer saya), partisi root (/) untuk bernaungnya direktori lain, dan partisi /home untuk menyimpan data-data. Partisi khusus untu direktori /home diperlukan untuk menghindari kehilangan data saat sistem anda crash dan perlu di-reinstalasi. Setiap partisi memiliki kebutuhan file sistem (fs) tersendiri. Partisi swap ber-fs swap. Partisi root (/) dengan kapasitas minimal 2 Gb, ber-fs (pilih saja) ext2, ext3 atau Reiserfs.

Bila anda meng-instal sistem operasi lain dalam komputer anda (multi-OS) anda akan membutuhkan partisi primer FAT/NTFS untuk Windows. Partisi primer BSD, untuk *BSD. Dan satu partisi swap untuk digunakan bersama-sama jika anda menginsta Linux lebih dari satu.

Mungkin anda juga membutuhkan sebuah partisi khusus untuk menampung dan mem-pertukarkan data-data, pastikan partisi ini ber-tipe FAT/FAT 32. File sistem jenis FAT/FAT 32 merupakan jenis file sistem yang dapat di baca dengan mudah oleh OS mana-pun.

Install Debian GNU/linux pakai PPPoE

Posted by aribowo21 on January 29, 2009

Installing Debian GNU/Linux using PPP over Ethernet (PPPoE)

In some countries PPP over Ethernet (PPPoE) is a common protocol for broadband (ADSL or cable) connections to an Internet Service Provider. Setting up a network connection using PPPoE is not supported by default in the installer, but can be made to work very simply. This section explains how.

The PPPoE connection set up during the installation will also be available after the reboot into the installed system (see Chapter 7, Booting Into Your New Debian System).

To have the option of setting up and using PPPoE during the installation, you will need to install using one of the CD-ROM/DVD images that are available. It is not supported for other installation methods (e.g. netboot or floppy).

Installing over PPPoE is mostly the same as any other installation. The following steps explain the differences.

  • Boot the installer with modules=ppp-udeb as boot parameter. This means that at the boot prompt you should enter:
    install modules=ppp-udeb

    or, if you prefer using the graphical installer:

    installgui modules=ppp-udeb

    This will ensure the component responsible for the setup of PPPoE (ppp-udeb) will be loaded and run automatically.

  • Follow the regular initial steps of the installation (language, country and keyboard selection; the loading of additional installer components[24]).
  • The next step is the detection of network hardware, in order to identify any Ethernet cards present in the system.
  • After this the actual setup of PPPoE is started. The installer will probe all the detected Ethernet interfaces in an attempt to find a PPPoE concentrator (a type of server which handles PPPoE connections).

    It is possible that the concentrator will not to be found at the first attempt. This can happen occasionally on slow or loaded networks or with faulty servers. In most cases a second attempt to detect the concentrator will be successful; to retry, select Configure and start a PPPoE connection from the main menu of the installer.

  • After a concentrator is found, the user will be prompted to type the login information (the PPPoE username and password).
  • At this point the installer will use the provided information to establish the PPPoE connection. If the correct information was provided, the PPPoE connection should be configured and the installer should be able to use it to connect to the Internet and retrieve packages over it (if needed). If the login information is not correct or some error appears, the installer will stop, but the configuration can be attempted again by selecting the menu entry Configure and start a PPPoE connection.

[24] The ppp-udeb component is loaded as one of the additional components in this step. If you want to install at medium or low priority (expert mode), you can also manually select the ppp-udeb instead of entering the “modules” parameter at the boot prompt.
