Sebuah Catatan Kecil
Hanya untuk mengingat ketika lupa

Restart Ubuntu hang GUI
02 Mei 2011
Untuk mengatasi masalah ini, sebenarnya Fedora sudah menyediakan solusi sederhana, yaitu dengan menggunakan yumdownloader. Perintah yumdownloader ini dapat melakukan download otomatis sebuah paket rpm lengkap dengan seluruh dependency yang dibutuhkan sehingga kita tidak perlu berulang-ulang melakukan download paket-paket pelengkap.
Penggunaan yumdownloader adalah sebagai berikut:
Code:
[redya@localhost]$ yumdownloader --resolve
Contohnya:
Code:
[redya@localhost]$ yumdownloader --resolve httpd
Dengan perintah tersebut maka paket httpd dan seluruh paket-paket pendukung yang dibutuhkan akan didownload secara otomatis untuk kemudian dapat di-copy dan digunakan pada komputer Fedora lain yang tidak memiliki akses internet.
Tips kecil untuk instalasi rpm adalah dengan menggunakan perintah "rpm -Uvh" dan bukannya "rpm -i" karena dengan menggunakan parameter -U maka ketika paket yang sama telah terinstall sebelumnya, program rpm akan secara otomatis melakukan update sementara parameter -i tidak melakukan hal tersebut. Contoh:
Code:
[root@localhost ~]#rpm -Uvh cnijfilter-common-3.00-1.i386.rpm cnijfilter-ip1900series-3.00-1.i386.rpm

Menampilkan file yang tersembunyi
(hmm... padahal cuma di hidden)
trik nya sangat mudah, hanya masuk ke drive-nya
misalkan di flash disk dengan alamat drive F:
maka trik yang paling gampang adalah
1. masuk ke command line dengan cara start/run/ketikkan "cmd"
2. masuk ke drivenya dengan cara ketik "f:" enter
3. setelah masuk ke drive f: maka tinggal ketikkan "attrib -a -h -r -s /S /D" enter
4. dan lihatlah di win explore, maka filenyapun insyaalloh sudah terlihat....

MENGEMBALIKAN GRUB YANG TERSEMBUNYI / HILANG
Bapak Ibu yang dimuliakan oleh Alloh SWT, insyaalloh, aminn(waduwh kya Dakwah, semoga ALLOH SWT menakdirkan diriku menjadi Seorang Pendakwah, amin )
Langsung ke TKP aja lah... dr man berpanjang-panjang....
- Pertama-tama kita harus mempersiapkan Helena/Ubuntu Live CD, jika ngga punya bisa juga menggunakan bootloader dari flash disk
- Kemudian ubah settingan pada BIOS, CD atau flash disk pada urutan pertama (first boot option)
- Jika PC Anda sudah diset untuk boot ke CD-ROM, Anda bisa menunggu sampai layar pilihan boot Helena/Ubuntu muncul pilih saja Try Ubuntu (without any change on your computer)
- Setelah masuk Live CD Desktop jalankan Terminal dengan meng-klik menu Applications > Accessories > Terminal
- Cek partisi Linux kita dengan menggunakan perintah
sudo fdisk -l
- Setelah diketahui partisi Linuxnya (misalkan partisi Linux pada laptop saya adalah sda8), kemudian lakukan mounting seperti berikut ini:
sudo mount -t ext4 /dev/sda8 /mnt/
sudo mount -t proc proc /mnt/proc/
sudo mount -t sysfs sys /mnt/sys/
sudo mount -o bind /dev/ /mnt/dev/
sudo chroot /mnt /bin/bash
- Sekarang kita akan mengembalikan GRUB ke MBR, perintahnya
grub-install /dev/sda
- sekarang kita akan mengembalikan kedalam partisi Linuxnya (dalam hal ini lokasi partisi Linux laptop saya berada di /dev/sda8), perintahnya
grub-install /dev/sda8
- Jika semuanya berjalan mulus (semulus jalan tol pantura:wkkwkwk) grubnya pasti telah kembali seperti semula

MOUNT OTOMATIS NTFS DI UBUNTU dan Sodaranya
fdisk -l
misal kan partisi NTFS anda adalah sda1, sda5, sda 6
buka edit file fstab dengan cara :
gedit /etc/fstab
dan isikan 3 baris di bawah ini, bisa di posisi paling belakang
/dev/sda1 /media/drive_c ntfs defaults 0 0
/dev/sda5 /media/drive_d ntfs defaults 0 0
/dev/sda6 /media/drive_e ntfs defaults 0 0
buat folder drive_c dan lainnya
mkdir /media/drive_c
mkdir /media/drive_d
mkdir /media/drive_e
reboot komp,
udah deh mount otomatisnya keluar,,,,
' " +semoga bermanfaat+ " '
Setting + Install Samba
1. Instal aplikasi sambanya
sudo apt-get install samba smbfs
2. Trus klo udah tinggal edit file konfigurasinya
sudo gedit /etc/samba/smb.conf
3. Atur security dengan cara
Cari baris ; security = user , hilangkan tanda ;
kemudian ganti menjadi security = share
4. Tambahkan baris perintah untuk menentukan nama share dan folder yang akan dishare. misal saya punya folder /home/share ingin saya sharing dengan nama master, maka tambahkan baris dibawah ini pada file /etc/samba/smb.conf
[folder_share]
comment = ini folderku loh
path = /home/share
public = yes
browseable = yes
writable = no # ganti dengan yes jika ingin full share
5. Jalankan ulang layanan sambanya
sudo /etc/init.d/samba restart
Trus bagaimana mengaksesnya ?
Sama seperti pada NFS, kita harus membuat sebuah direktori untuk proses mounting
sudo mkdir /mnt/samba
Lakukan proses mounting dengan perintah
sudo smbmount //192.168.0.1/folder_share /mnt/samba
atau
masuk ke nautilus / dolphin, di address bar ketikkan smb://192.168.0.1/folder_share
Dengan asumsi bahwa ip 192.168.0.1 ada komputer dimana folder dishare berada. jika ditanya password, tekan tombol enter saja
atau bisa juga dengan menggunakan smbclient untuk mengetesnya dengan mengetikan
sudo smbclient //192.168.0.1/folder_share
ketik : quit untuk keluar.
Nah, sekarang anda sudah dapat melakukan proses sharing untuk Linux. trus bagaimana cara mounting jika share berada pada komputer windows ? caranya sama saja, lihat proses mounting samba diatas

How to Reset MySQL Root Password
Resetting the Root Password on Windows Systems
Use the following procedure for resetting the password for any MySQL root
accounts on Windows:
Log on to your system as Administrator.
Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager:
Start Menu -> Control Panel -> Administrative Tools -> Services
Then find the MySQL service in the list, and stop it.
If your server is not running as a service, you may need to use the Task Manager to force it to stop.
Create a text file and place the following statements in it. Replace the password with the password that you want to use.
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root'; FLUSH PRIVILEGES;
The
UPDATE
andFLUSH
statements each must be written on a single line. TheUPDATE
statement resets the password for all existingroot
accounts, and theFLUSH
statement tells the server to reload the grant tables into memory.Save the file. For this example, the file will be named
C:\mysql-init.txt
.Open a console window to get to the command prompt:
Start Menu -> Run -> cmd
Start the MySQL server with the special
--init-file
option:C:\>
C:\mysql\bin\mysqld-nt --init-file=C:\mysql-init.txt
If you installed MySQL to a location other than
C:\mysql
, adjust the command accordingly.The server executes the contents of the file named by the
--init-file
option at startup, changing eachroot
account password.You can also add the
--console
option to the command if you want server output to appear in the console window rather than in a log file.If you installed MySQL using the MySQL Installation Wizard, you may need to specify a
--defaults-file
option:C:\>
"C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld-nt.exe"
--defaults-file="C:\Program Files\MySQL\MySQL Server 5.0\my.ini"
--init-file=C:\mysql-init.txt
The appropriate
--defaults-file
setting can be found using the Services Manager:Start Menu -> Control Panel -> Administrative Tools -> Services
Find the MySQL service in the list, right-click on it, and choose the
Properties
option. ThePath to executable
field contains the--defaults-file
setting.After the server has started successfully, delete
C:\mysql-init.txt
.Stop the MySQL server, then restart it in normal mode again. If you run the server as a service, start it from the Windows Services window. If you start the server manually, use whatever command you normally use.
You should now be able to connect to MySQL as root
using the new password.
Resetting the Root Password on Unix Systems
MySQL Enterprise. For expert advice on security-related issues, subscribe to the MySQL Enterprise Monitor. For more information, see http://www.mysql.com/products/enterprise/advisors.html.
Use the following procedure for resetting the password for any MySQL root
accounts on Unix. The instructions assume that you will start the server so that it runs using the Unix login account that you normally use for running the server. For example, if you run the server using the mysql
login account, you should log in as mysql
before using the instructions. (Alternatively, you can log in as root
, but in this case you must start mysqld with the --user=mysql
option. If you start the server as root
without using --user=mysql
, the server may create root
-owned files in the data directory, such as log files, and these may cause permission-related problems for future server startups. If that happens, you will need to either change the ownership of the files to mysql
or remove them.)
Log on to your system as the Unix
mysql
user that the mysqld server runs as.Locate the
.pid
file that contains the server's process ID. The exact location and name of this file depend on your distribution, host name, and configuration. Common locations are/var/lib/mysql/
,/var/run/mysqld/
, and/usr/local/mysql/data/
. Generally, the file name has an extension of.pid
and begins with eithermysqld
or your system's host name.You can stop the MySQL server by sending a normal
kill
(notkill -9
) to the mysqld process, using the path name of the.pid
file in the following command:shell>
kill `cat /mysql-data-directory/host_name.pid`
Note the use of backticks rather than forward quotes with the
cat
command; these cause the output ofcat
to be substituted into thekill
command.Create a text file and place the following statements in it. Replace the password with the password that you want to use.
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root'; FLUSH PRIVILEGES;
The
UPDATE
andFLUSH
statements each must be written on a single line. TheUPDATE
statement resets the password for all existingroot
accounts, and theFLUSH
statement tells the server to reload the grant tables into memory.Save the file. For this example, the file will be named
/home/me/mysql-init
. The file contains the password, so it should not be saved where it can be read by other users.Start the MySQL server with the special
--init-file
option:shell>
mysqld_safe --init-file=/home/me/mysql-init &
The server executes the contents of the file named by the
--init-file
option at startup, changing eachroot
account password.After the server has started successfully, delete
/home/me/mysql-init
.
You should now be able to connect to MySQL as root
using the new password.
Alternatively, on any platform, you can set the new password using the mysql client (but this approach is less secure):
Stop mysqld and restart it with the
--skip-grant-tables
option.Connect to the mysqld server with this command:
shell>
mysql
Issue the following statements in the mysql client. Replace the password with the password that you want to use.
mysql>
UPDATE mysql.user SET Password=PASSWORD('MyNewPass')
->WHERE User='root';
mysql>FLUSH PRIVILEGES;
You should now be able to connect to MySQL as root
using the new password.
