The sudo command

If you have come across Linux, you are probably aware of the command line. Ubuntu puts a lot of reliance upon the sudo command while working at the command line. This command is used in front of other commands to tell Ubuntu that you want to run the specified command with super user powers. This sounds really special, and it actually is. When you work using the sudo command, you can make wide-ranging changes to your system that impact the way it runs. Be extra careful when running any command prefixed with sudo, however; a wrong option or incorrect command can have devastating consequences.

The use of sudo is straightforward. All you have to do is enter it like this:

$ sudo command commandoptions

Just replace the word command with the command that you want to run, along with any options. For example, the following command opens your xorg.conf file in vi and enables you to make any changes as the super user before being able to save it:

$ sudo vi /etc/X11/xorg.conf

Whenever you execute a command using sudo, you are prompted for your password. This
is the same password that you use to log in to Ubuntu, so it is important that you remember it.

Sometimes, however, you may want to work with a classic root prompt instead of having to type sudo in front of every command (perhaps if you have to work with lots of commands at the command line that require super-user access, for example). sudo enables you to do this by using the sudo -i command. Again, you are prompted for your password, which you should enter, after which Ubuntu gives you the standard root prompt, as follows:

#

From here, you can execute any command without having to keep entering sudo.

Cara Instalasi Plugin Flash Player 9 di Ubuntu 7.10

Dari pengalaman pahit sebelumnya, mulai sekarang saya akan mencoba (sebisa mungkin) mendokumentasikan apa-apa yang sudah saya kerjakan di PC ini, terutama dengan sistem Linux Ubuntu 7.10 yang baru hari ini diinstall. Saya pikir membuat dokumentasi untuk Linux sangat penting karena saya kurang familier dengan linux. Dari tahun 2001 sampai sekarang, sudah sering pakai linux tapi hanya dalam kapasitas sekedar coba-coba, gak pernah belajar lebih dalam, jadi selalu lupa apa dan bagaimana di linux.

Dokumentasi pertama ini sudah saya tulis di file text, posting saja disini yaitu "cara instalasi plugin flash player 9". Ini yang pertama saya lakukan karena memang browsing kerjaannya he he.


Ini isi file dokumentasinya:

Pentingnya Backup Data

Hari ini saya melakukan kesalahan fatal, bisa dibilang dan memang demikian karena keteledoran saya (human error).

Sebelumnya saya mencoba menginstall Linux Ubuntu 7.10 di PC Yessi (dual OS dengan WinXP) (sebelumnya pakai PCLinuXOS gak puas) tapi tidak pernah berhasil, selalu hang ketika memasuki step (tahapan) ke 4 dari 7 step semuanya (ada juga yang 6 step, tergantung option awal waktu booting). Pada tahap ini kita diminta untuk mengatur lokasi partisi untuk sistem linux. Saya selalu memilih opsi manual karena akan dibuat dual OS dengan Windows XP. Tidak tahu kenapa kok gagal terus padahal udah beberapakali saya atur partisinya, baik dengan tool partisi dari Ubuntu atau dengan Partition Magic di windows.


Lama-lama kesal juga akhirnya pada tahap ke 4 saya pilih opsi yang bukan manual (lupa tulisannya). Sekilas saya pikir opsi tersebut akan otomatis memilih partisi yang memiliki file sistem ext3 beserta swapnya untuk sistem linux. Karena tidak dicermati (tidak baca-baca dulu) saya klik terus saja tombol forward (next di windows). Finish.

Mulai curiga ketika booting, di GRUB Loader tidak ada OS lain selain Ubuntu. Mulai deg-degan.
Tidak cek ini itu dulu langsung saja saya restart, booting dengan CD Windows XP, dan ternyata memang, partisi HILANG semua, LOST, EUWEUH. Aduh, alah, kumaha yeuh (gima nih)??!!!??. yang ada cuma partisi sistem linux dan swapnya. Hardisk 80 GByte dilahap semua oleh Ubuntu 7.10.

Eng..ing..eng borogodododd...

Ya sudahlah, data-data penting hilang semua, skripsi orang (yang sudah dan sedang diprogress), aplikasi yang pernah dibuat, dokumen pribadi (kenangan). Kalau lagu, film, software bisa nyari lagi, tapi data-data penting pribadi? :(

Yang menyakitkan dan menyesal adalah saya tidak pernah buat backupnya dalam bentuk CD atau jenis penyimpanan lainnya.

Akhirnya hari ini datang juga, data hilang semua (tak terbayangkan sebelumnya karena selama ini merasa aman dan baik-baik saja). Inilah akibatnya kalau segala sesuatu tidak dipelajari dengan baik terlebih dahulu. Tanya atau baca-baca dulu.

OK, saya coba instalasi ulang, hardisk partisi ulang. Pertama install Windows XP, selanjutnya install Ubuntu nya. Apa gerangan? BISA, LANCAR, GAK NGEHANG :( :) :(

Lemas deh, terlambat sudah, nasi sudah menjadi bubur.

Ruang Kerja Baru

Kemarin baru pindah ke ruangan baru. Cukup melelahkan karena angkut-angkut barang kantor yang berat-berat. Yang bikin kucel adalah ketika naik atap untuk lepas kabel antena WIPLL (Wireless IP Local Loop). Di bawah ini sebagian foto yang saya ambil hari ini.



Ini meja kerja saya (sebenarnya siapa aja bisa pindah-pindah meja). Ada laptop, HP, remote AC dan segelas kopi. Hanya monitor aja yang kurang matching (CRT), soalnya monitor aslinya (DELL LCD 15") hilang kabel VGA nya (masih dicari).




Kalau ini untuk NMS (Network Manajemen System). Ada dua buah modem ADSL router wireless, ASUS(putih) dan PROLINK. satu untuk NMS dan satu lagi untuk speedy.



Nah yang ini pintu keluar kami (proxy squid freebsd). Sekali-kali kami main keluar melalui pintu ini, he he he. Baru selesai di clearkan cachenya, soalnya kemarin sempat ngadat. Pas dicek ternyata cachenya sudah kepenuhan (kok ga clear otomatis ya? padahal udah disetting di squid.conf nya. Ntar ja dicek lg)



Begh, di depan ruangan ada layar TV 47" 2 buah. kemarin Pak Herry, saya dan yadi yang pasangnya. Untuk pasang TV sebesar ini di dinding kita butuh meteran, waterpass, bor listrik, kunci pas dan obeng. Mudah kok pasangnya. sayang sampai hari ini belum dinyalakan karena ada kendala teknis.



Pemandannya kurang indah ni. Ini pemandangan dari jendela sisi belakang meja saya.

Masih ada bagian-bagian yang belum difoto, seperti mushola (blm resmi), dapur dan meja makan meja tempat ngobrol agak serius.
