Cara Menginstall Firefox 5 di Ubuntu 10.04 via PPA
Akhirnya aku mencoba mencari sumber repo yang lain, siapa tahu ada Mozilla Firefox 5. Daripada harus compile dan built sendiri dari .tar.bz2, takutnya kurang bisa 'nge-link' dengan paket-paket yang lainnya.
Puji Tuhan, aku menemukannya. Diambil dari PPA, bukan dari mirror base repository manapun. Mau ikutan upgrade ? Silahkan ikuti langkah-langkah berikut dibawah ini :
1. Buka Terminal (untuk lebih cepatnya, tekan : CTRL+ALT+T)
2. Ketikkan : sudo add-apt-repository ppa:mozillateam/firefox-stable
3. Setelah PPA terpasang, lakukan update keseluruhan paket : sudo apt-get update
4. Setelah paket terupdate dengan yang baru, maka tidak perlu menghapus firefox yang sudah ada (yang lama, yang sudah terinstall di ubuntu anda), cukup diupgrade saja dengan mengetikkan : sudo apt-get upgrade.
5. Selamat menikmati Mozilla Firefox 5!

Setting Mikrotik External Proxy
Solusinya ? Gunakan web proxy squid external.
Berikut sedikit informasi yang mungkin dapat membantu saudara dalam mengkonfigurasi Mikrotik untuk menggunakan external proxy squid.
Berikut skema diagram jaringannya :
Modem---Mikrotik---Client
------------|
----------Proxy
Misal :
dari ISP=192.168.1.1/24
Mikrotik=eth0 (ke modem)192.168.1.2/24
Mikrotik=eth1(ke proxy)192.168.2.1/24
Mikrotik=eth2(ke client)192.168.3.1/24
Proxy=192.168.2.2/24
Client=192.168.3.2-10/24
Terlihat bahwa kedudukan server external proxy squid disini adalah sejajar dengan server Mikrotik. Dengan demikian pastikan client berada dibawah server external proxy ini, jangan sampai client bisa mengakses server external proxy ini secara langsung.
Untuk proxy, lakukan konfigurasi pada bagian NAT sebagai berikut :
/ip firewall nat add chain=src-nat src-address=192.168.2.2/24 out-interface=eth0 action=masquerade
sedangkan NAT untuk komputer client :
/ip firewall add chain=src-nat src-address=192.168.3.2-192.168.3.10 out-interface=eth0 action=masquerade
Kemudian jangan lupa, client dipaksakan harus browsing lewat proxy (misal proxy dibuka diport 3128) maka :
/ip firewall chain=dst-nat protocol=tcp dst-port=80 in-interface=eth2 to-addresses=192.168.2.2 to-ports=3128
Dan terakhir, setting routing di Mikrotiknya mengarah ke ISP :
0.0.0.0/0 192.168.1.1
Mudah bukan ? Selamat mencoba :)

Sinkronisasi dengan server RPMFUSION.ORG
Nah, dimanakah server yang menyimpan file-file .rpm special ini ? RPMFUSION.ORG !
Apabila anda mengatur sejumlah komputer dengan versi distro yang sama, ada baiknya anda membangun server repository local supaya bandwidth internet anda tidak habis serta proses downloadnya juga tidak akan memakan waktu yang lama.
Berikut perintah yang bisa anda pakai untuk melakukan sinkronisasi dengan server RPMFUSION.ORG (tentunya perlu sedikit disesuaikan dengan path local anda) :
1. Sinkronisasi FREE
rsync -Pav --delete-after rsync://download1.rpmfusion.org/rpmfusion/free/fedora/releases/13/Everything/i386/os/ /var/www/html/free/fedora/releases/13/Everything/i386/os/
2. Sinkronisasi FREE-UPDATES
rsync -Pav --delete-after --exclude=debug rsync://download1.rpmfusion.org/rpmfusion/free/fedora/updates/13/i386/ /var/www/html/free/fedora/updates/13/i386/
3. Sinkronisasi NONFREE
rsync -Pav --delete-after rsync://download1.rpmfusion.org/rpmfusion/nonfree/fedora/releases/13/Everything/i386/os/ /var/www/html/nonfree/fedora/releases/13/Everything/i386/os
4. Sinkronisasi NONFREE-UPDATES
rsync -Pav --delete-after --exclude=debug rsync://download1.rpmfusion.org/rpmfusion/nonfree/fedora/updates/13/i386/ /var/www/html/nonfree/fedora/updates/13/i386

Install Driver Printer HP LaserJet 1020 di Linux Fedora 11
Ternyata ini tidak berhasil ! Perintah printing sudah dikirim namun printer diam saja, tidak menghasilkan apa-apa. Setelah bertanya kepada Windra (salah seorang staff ahli di bidang linux) ternyata untuk HP LaserJet 1020 bukan pakai Gutenprint, tapi foo2zjs. Wah, apalagi ini, langsung saya googling dan ketemu. Ternyata foo2zjs ini adalah driver external (third party) yang secara khusus memuat driver-driver printer HP LaserJet 1020.
Baik, langsung saya kerjakan langkah-langkah berikut ini :
1. Mendownload file drivernya dari Internet. Ambil disini -> http://foo2zjs.rkkda.com/foo2zjs.tar.gz
2. Extract file tersebut dengan menggunakan perintah : tar -zxvf foo2zjs.tar.gz
3. Saatnya kita compilasi source code ini ... dengan mengetikkan : make kemudian make install dan make install-hotplug
4. Restart CUPS dengan mengetikkan : make cups
5. Selesai deh ... tinggal di add lagi di CUPS Web Interfacenya...
Selamat mencoba !

About IDE, SATA, and SCSI Drives
IDE Drives
To save costs, many small business systems will probably use IDE disks, but they do have some limitations.
- The total length of an IDE cable can be only a few feet long, which generally limits IDE drives to small home systems.
- IDE drives do not hot swap. You cannot replace them while your system is running.
- Only two devices can be attached per controller.
- The performance of the IDE bus can be degraded by the presence of a second device on the cable.
- The failure of one drive on an IDE bus often causes the malfunctioning of the second device. This can be fatal if you have two IDE drives of the same RAID set attached to the same cable.
For these reasons, I recommend you use only one IDE drive per controller when using RAID, especially in a corporate environment. In a home or SOHO setting, IDE-based software RAID may be adequate.
Serial ATA Drives
Serial ATA type drives are rapidly replacing IDE, or Ultra ATA, drives as the preferred entry level disk storage option because of a number of advantages:
- The drive data cable can be as long as 1 meter in length versus IDE's 18 inches.
- Serial ATA has better error checking than IDE.
- There is only one drive per cable which makes hot swapping, or the capability to replace components while the system is still running, possible without the fear of affecting other devices on the data cable.
- There are no jumpers to set on Serial ATA drives to make it a master or slave which makes them simpler to configure.
- IDE drives have a 133Mbytes/s data rate whereas the Serial ATA specification starts at 150 Mbytes/sec with a goal of reaching 600 Mbytes/s over the expected ten year life of the specification.
If you can't afford more expensive and faster SCSI drives, Serial ATA would be the preferred device for software and hardware RAID
SCSI Drives
SCSI hard disks have a number of features that make them more attractive for RAID use than either IDE or Serial ATA drives.
- SCSI controllers are more tolerant of disk failures. The failure of a single drive is less likely to disrupt the remaining drives on the bus.
- SCSI cables can be up to 25 meters long, making them suitable for data center applications.
- Much more than two devices may be connected to a SCSI cable bus. It can accommodate 7 (single-ended SCSI) or 15 (all other SCSI types) devices.
- Some models of SCSI devices support "hot swapping" which allows you to replace them while the system is running.
- SCSI currently supports data rates of up to 640 Mbytes/s making them highly desirable for installations where rapid data access is imperative.
SCSI drives tend to be more expensive than IDE drives, however, which may make them less attractive for home use.
Replacing A Failed Hard Drive In A Software RAID1 Array
This guide shows how to remove a failed hard drive from a Linux RAID1 array (software RAID), and how to add a new hard disk to the RAID1 array without losing data.
I do not issue any guarantee that this will work for you!
1 Preliminary Note
In this example I have two hard drives, /dev/sda and /dev/sdb, with the partitions /dev/sda1 and /dev/sda2 as well as /dev/sdb1 and /dev/sdb2.
/dev/sda1 and /dev/sdb1 make up the RAID1 array /dev/md0.
/dev/sda2 and /dev/sdb2 make up the RAID1 array /dev/md1.
/dev/sda1 + /dev/sdb1 = /dev/md0
/dev/sda2 + /dev/sdb2 = /dev/md1
/dev/sdb has failed, and we want to replace it.
2 How Do I Tell If A Hard Disk Has Failed?
If a disk has failed, you will probably find a lot of error messages in the log files, e.g. /var/log/messages or /var/log/syslog.
You can also run
cat /proc/mdstat
and instead of the string [UU] you will see [U_] if you have a degraded RAID1 array.
3 Removing The Failed Disk
To remove /dev/sdb, we will mark /dev/sdb1 and /dev/sdb2 as failed and remove them from their respective RAID arrays (/dev/md0 and /dev/md1).
First we mark /dev/sdb1 as failed:
mdadm --manage /dev/md0 --fail /dev/sdb1
The output of
cat /proc/mdstat
should look like this:
server1:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid5] [raid4] [raid6] [raid10]
md0 : active raid1 sda1[0] sdb1[2](F)
24418688 blocks [2/1] [U_]
md1 : active raid1 sda2[0] sdb2[1]
24418688 blocks [2/2] [UU]
unused devices:
Then we remove /dev/sdb1 from /dev/md0:
mdadm --manage /dev/md0 --remove /dev/sdb1
The output should be like this:
server1:~# mdadm --manage /dev/md0 --remove /dev/sdb1
mdadm: hot removed /dev/sdb1
And
cat /proc/mdstat
should show this:
server1:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid5] [raid4] [raid6] [raid10]
md0 : active raid1 sda1[0]
24418688 blocks [2/1] [U_]
md1 : active raid1 sda2[0] sdb2[1]
24418688 blocks [2/2] [UU]
unused devices:
Now we do the same steps again for /dev/sdb2 (which is part of /dev/md1):
mdadm --manage /dev/md1 --fail /dev/sdb2
cat /proc/mdstat
server1:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid5] [raid4] [raid6] [raid10]
md0 : active raid1 sda1[0]
24418688 blocks [2/1] [U_]
md1 : active raid1 sda2[0] sdb2[2](F)
24418688 blocks [2/1] [U_]
unused devices:
mdadm --manage /dev/md1 --remove /dev/sdb2
server1:~# mdadm --manage /dev/md1 --remove /dev/sdb2
mdadm: hot removed /dev/sdb2
cat /proc/mdstat
server1:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid5] [raid4] [raid6] [raid10]
md0 : active raid1 sda1[0]
24418688 blocks [2/1] [U_]
md1 : active raid1 sda2[0]
24418688 blocks [2/1] [U_]
unused devices:
Then power down the system:
shutdown -h now
and replace the old /dev/sdb hard drive with a new one (it must have at least the same size as the old one - if it's only a few MB smaller than the old one then rebuilding the arrays will fail).
4 Adding The New Hard Disk
After you have changed the hard disk /dev/sdb, boot the system.
The first thing we must do now is to create the exact same partitioning as on /dev/sda. We can do this with one simple command:
sfdisk -d /dev/sda | sfdisk /dev/sdb
You can run
fdisk -l
to check if both hard drives have the same partitioning now.
Next we add /dev/sdb1 to /dev/md0 and /dev/sdb2 to /dev/md1:
mdadm --manage /dev/md0 --add /dev/sdb1
server1:~# mdadm --manage /dev/md0 --add /dev/sdb1
mdadm: re-added /dev/sdb1
mdadm --manage /dev/md1 --add /dev/sdb2
server1:~# mdadm --manage /dev/md1 --add /dev/sdb2
mdadm: re-added /dev/sdb2
Now both arays (/dev/md0 and /dev/md1) will be synchronized. Run
cat /proc/mdstat
to see when it's finished.
During the synchronization the output will look like this:
server1:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid5] [raid4] [raid6] [raid10]
md0 : active raid1 sda1[0] sdb1[1]
24418688 blocks [2/1] [U_]
[=>...................] recovery = 9.9% (2423168/24418688) finish=2.8min speed=127535K/sec
md1 : active raid1 sda2[0] sdb2[1]
24418688 blocks [2/1] [U_]
[=>...................] recovery = 6.4% (1572096/24418688) finish=1.9min speed=196512K/sec
unused devices:
When the synchronization is finished, the output will look like this:
server1:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid5] [raid4] [raid6] [raid10]
md0 : active raid1 sda1[0] sdb1[1]
24418688 blocks [2/2] [UU]
md1 : active raid1 sda2[0] sdb2[1]
24418688 blocks [2/2] [UU]
unused devices:
That's it, you have successfully replaced /dev/sdb!

Reset Openfire Admin Password
==================
cari file : openfire.xml, editlah file itu kemudian carilah bagian yang menyerupai berikut dibawah ini :
silahkan ditambahkan baris yang berwarna merah, simpan perubahan yang telah dilakukan kemudian restartlah openfire anda.
External Database (MySQL) :
=====================
1. Login to MySQL and use openfire database. I use the command:mysql -uroot -p openfire
2. Display the password for the admin user with the query:select password from jiveUser where username = 'admin';
This will display the initially chosen password for admin. However if you have at any time changed the password from the administration screen then it will display NULL instead.
After first change the password is encrypted and stored in the encryptedPassword field and cannot be recovered.
However you can change the password even without knowing the original password.
How to change Openfire admin password
Change the admin (or any other users) password by setting password field to chosen value and encryptedPassword field to null. For example here is the query to set the admin password to 123456:update jiveUser set password='123456', encryptedPassword = null where username ='admin';
This will change the current admin password to 123456. Remember to change it to a different value after you login to the admin console. This will also have the side-effect of encrypting your password in database for added security.
Note: Openfire admin console is available at http://localhost:9090
