$ defaults write com.apple.screencapture location ~ / Desktop /
$ killall SystemUIServer

Then please try again to capture the screen. To capture the entire screen display use Cmd-Shift-3, if you want to just capture some of the screen you can use Cmd-Shift-4.

I copy the following files from Ubuntu.

$cat /usr/lib64/php/maxlifetime

Then we create cron file to auto delete the sessions files.

$cat /etc/cron.d/php

That’s it.

Selanjutnya kita install Android SDK. Download Android SDK di sini[2]. Android SDK cukup kita extract saja, misal kita extract di /Users/budiw/Downloads/android-sdk.

Setelah Android SDK terinstall, kita download terlebih dahulu image android platform. Caranya kita buka terminal/console. Kemudian kita ketik perintah-perintah dibawah ini.

$cd /Users/budiw/Downloads/android-sdk
$tools/android

Kita tinggal centang Android versi berapa yang mau diinstall. Karena game yang akan dimainkan ‘katanya’ jalan di Android 2.3.3, maka saya centang yang Android 2.3.3 (API 10).

Klik “Install …”

Setelah Image Android sudah diinstall. Kita perlu membuat sebuah Emulator HP Android. Berbeda dengan versi Windows, versi OS X tidak dilengkapi program AVD Manager.exe, jadi kita harus buat manual menggunakan terminal/console. Referensi dari sini[3] dan sana[4].

Kita lihat dulu ada berapa emulator HP yg bisa kita pakai.

$tools/android list targets
Available Android targets:
----------
id: 1 or "android-10"
Name: Android 2.3.3
Type: Platform
API level: 10
Revision: 2
Skins: HVGA, QVGA, WQVGA400, WQVGA432, WVGA800 (default), WVGA854
ABIs : armeabi
----------
id: 2 or "Google Inc.:Google APIs:10"
Name: Google APIs
Type: Add-On
Vendor: Google Inc.
Revision: 2
Description: Android + Google APIs
Based on Android 2.3.3 (API level 10)
Libraries:
* com.android.future.usb.accessory (usb.jar)
API for USB Accessories
* com.google.android.maps (maps.jar)
API for Google Maps
Skins: WVGA854, WQVGA400, HVGA, WQVGA432, WVGA800 (default), QVGA
ABIs : armeabi

Baru kemudian kita buat AVD (Android Virtual Device).

$tools/android create avd -n hpgames -t 1 -p /Users/budiw/Downloads/hpgames
Auto-selecting single ABI armeabi
Android 2.3.3 is a basic Android platform.
Do you wish to create a custom hardware profile [no]
Created AVD 'cobahp' based on Android 2.3.3, ARM (armeabi) processor,
with the following hardware config:
hw.lcd.density=240
vm.heapSize=24
hw.ramSize=256

Setelah jadi, kita jalankan dengan perintah emulator.

$tools/emulator -avd hpgames

Setelah emulator sudah jalan, baru kita install game yang diinginkan. Kita lihat dulu nama devices-nya.

$platform-tools/adb devices

List of devices attached
emulator-5554	device

$platform-tools/adb -s emulator-5554 install namafile.apk
1246 KB/s (4213460 bytes in 3.300s)
pkg: /data/local/tmp/namafile.apk
Success

Kemudian bisa kita lihat di menu sudah terinstall game tersebut.

Selamat, siapkan waktu dan tenaga untuk kecanduan.

That’s because named aren’t allowed to write to directory /etc/bind/db/in. To solve this issue, open apparmor profile of named (/etc/apparmor.d/usr.sbin.named), add this line right after ‘/etc/bind/** r,‘ :

/etc/bind/db/** rw,

Restart the apparmor and then restart named.

Halo semua, kali ini saya cuma mau share pengalaman dalam urusan telpon menelpon. Dari semua operator yang pernah saya pakai. Kali ini cuma Simpati yang sangat cocok untuk saya.

Saya sangat sering berhubungan dengan client, baik dihubungi maupun menghubungi. Karena pekerjaan saya yang sering membuat saya berpindah-pindah lokasi, maka jelas saya sangat membutuhkan sebuah telepon yang cukup luas coverage-nya.

Tentu saja, kebutuhan tentang coverage ini, cuma simpati yang bisa memenuhinya. Dari sisi harga, sekarang ada yang paket Simpati Freedom. Dimana hal ini membuat saya lebih mudah tanpa harus mempunyai banyak kartu. Karena client saya biasanya menggunakan operator yang lain dan dengan Simpati Freedom kita bisa Ngobrol Tanpa Batas ke SEMUA OPERATOR. Ya, SEMUA OPERATOR.

Bayangkan keuntungan yang bisa saya peroleh, Saya bisa menghemat pengeluaran dan jelas, bisa menambah pemasukan. Pemasukan? Ya, karena saya bisa bernegosiasi tentang project ataupun masalah dengan client melalui telepon. Hemat waktu, tenaga dan yang pasti client puas dapat berkonsultasi.

Oh iya, untuk mengaktifkannya, cukup mudah. Tinggal kirim sms 8999 dengan isi TM(spasi)TB. Kalo males tulis sms, ada cara lainnya kok,  tekan *999*55# dari kartu Simpati Freedom anda. Maka anda akan terdaftar di program Freedom

By the way, Promosi ini berlaku untuk kartu Simpati Freedom yang diaktifkan setelah tanggal 12 Oktober 2010. Jadi buat yg sudah pakai Simpati, ayo beli kartu perdana-nya sekarang juga. Cukup murah kok kartu perdananya.

Skema Program simPATI Freedom

Yang pasti cukup ingat angka berikut ini untuk mengaktifkan simPATI Freedom anda.

Sampai saat ini, cuma Simpati yang bisa memenuhi kebutuhan telekomunikasi saya.
Nyamannya pakai simPATI.

Mailman

Recently I Installed a mailing list manager on my mailserver. I use GNU’s mailman. It’s straightforward and simple and they have a web-based administration. I’m following this tutorial from wiki.ubuntu.com.

But unfortunately, this tutorial has some error in configuration. After a long search finally I found that, the line at /etc/mailman/mm_cfg.py should be MTA = None. But in the tutorial is MTA = Postfix.

The configuration error is not quickly found, because the mailing list is running as usual. I found this error on this situation.

My server is postfix and using virtual mail. I have a mailbox called dummybox@example.com. Then I create a lists called dummybox@lists.example.com. Everytime I send an email to dummybox@example.com, postfix try to deliver the email to mailman. And whoops, its error!

After changing MTA to None, this error dissapear.

Update #1:
I change the  MTA to None on wiki.ubuntu.com. Thank God it’s wiki, a collaborated pages. So I can change the error.

OpenBSD Logo

Hello all,

This time I need to play with OpenBSD, because I want to learn some software that doesn’t exist in Linux. It’s combination of spamd, relaydb and pf. The purpose of this, I want to get rid of spam as many as I could. Of course, with minimal efforts (cpu cycles, bandwidth, etc).

Installing OpenBSD is easy, you can follow some guidance by cibercity.biz here. After the install is finish, you will encounter another problem. Where’s the login prompt? Lucky you, on cibercity.biz tutorial, there’s also a tutorial how to get in the login prompt. It’s a problem with some kernel config, I don’t understand too much right now. Just follow the white rabbit.

Ta..da.. Now you’re ready to rock in ksh!

Update 14 Aug 2010:
After installation is success, you have another problem a head. The network interface card of KVM is very slow. After a little googling, no solution right now. Because spamd, relaydb and pf already ported to FreeBSD since 5.x, I’m switching to FreeBSD. The tutorial is here. Happy FreeBSDing..

By the way, This is the tutorial I want to achive, from benzedrine.cx.

I tried this with Ubuntu 10.04. This tutorial is not compatible with Ubuntu below 10.04.

First we set the getty, so we can log-in through serial console.

$ sudo vi /etc/init/ttyS0.conf
# ttyS0 - getty
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

respawn
exec /sbin/getty -L 38400 ttyS0 vt102

Then we setup the grub loader so it can show on serial ports too. Just adjust your grub configuration with this configuration.

$sudo vi /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=0
GRUB_TIMEOUT=1
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,38400n8"

# Uncomment to disable graphical terminal (grub-pc only)
GRUB_TERMINAL=serial
GRUB_SERIAL_COMMAND="serial --speed=38400 --unit=0 --word=8 --parity=no --stop=1"

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

After editing grub configuration, we update our grub with this command:

$sudo update-grub

Before we test the grub loader with serial, we should test the getty program. Now, on client computer, we install minicom program. I’m using USB2Serial that detected on port /dev/ttyUSB0. I use 38400 baud speed. Just adjust the 38400 with other speed if you like.

Let’s install the minicom program with this command:

$sudo apt-get install minicom

After that, launch the minicom program. Set the configuration like this. Press ^ao on the minicom screen.

+-----[configuration]------+
| Filenames and paths      |
| File transfer protocols  |
| Serial port setup        |
| Modem and dialing        |
| Screen and keyboard      |

| Save setup as..          |
| Exit                     |
+--------------------------+

Choose “Serial port setup”

+-----------------------------------------------------------------------+

| G - Software Flow Control : No                                        |
|                                                                       |
|    Change which setting?                                              |
+-----------------------------------------------------------------------+

After done configurating, Save it as default by choosing “Save setup as dfl”. Then Let’s try to initialized the serial by pressing ^am . If success then we have a login prompt.

Ubuntu 10.04 LTS ro-bb-fa-fb-fe ttyS0                                           

ro-bb-fa-fb-fe login:

On the login screen we know that we use serial console by “ttyS0″ It’s mean we use serial 0.

Buy Sabrent SBT-USC6M USB 2.0 to Serial (9-pin) DB-9 RS-232 (BLUE) at Amazon and get discounted price.

I’m curios who’s Google peering with? Finally a little Googling found this link, from IP to ASN http://www.team-cymru.org/Services/ip-to-asn.html Finding ASN from IP Address, turned out quite easily.

First we search first one ip from Google. We use the command ‘host www.google.com’ It would appear many ip, I Choose 72.14.213.147, then we use whois command:

whois -h -v whois.cymru.com 72.14.213.103

The result is as below

Warning: RIPE flags Used with a traditional server.
AS   |IP            | BGP Prefix     | CC   | Registry | Allocated  | U.S. Name
15169|72.14.213.103 | 72.14.212.0/23 | U.S. | ARIN     | 2004-11-10 | GOOGLE - Google Inc..

Left column is Google’s ASN. We enter into his looking glass HE.net so it looks like: http://bgp.he.net/AS15169

Please see BGP peering and statistics from Google.
