"SIOCSIFFLAGS: invalid argument"

Written By pcbolong on Thursday, September 29, 2011 | 4:12 AM

Ada teman yang curhat, saat dia mau set ip address untuk ether 0 di linux, muncul peringatan seperti ini : "SIOCSIFFLAGS: invalid argument"

Setelah di cek dan ricek, pesan kesalahan tersebut muncul saat terjadi dua hal, yaitu :
1. Salah perintah atau argument yang digunakan.
2. NIC atau lancard di ether yang bersangkutan tidak terdetek. Tidak terdetek di sini, bisa berarti rusak atau mati, dan bisa juga driver chipset lancard tidak didukung atau belum ada pada distro linux yg dipakai.

Solusi untuk penyebab yang pertama sudah jelas, kita bisa mencari di google atau membaca manual mengenai ipconfig.

Solusi untuk penyebab yang kedua, ada beberapa, diantaranya :
1. cek apakah lancard benar-benar sudah terdeteck oleh sistem operasi dengan perintah ifconfig -a . Jika ada nama chipset lancard dari keluaran nya, berarti lancard sudah terdeteck dan siap digunakan. Lalu bisa menggunakan perintah ifconfig eth0 192.168.10.3 netmask 255.255.255.0 up untuk setting ip atau dengan menggunakan perintah netconfig .

2. Jika lancard ternyata tidak ditampilkan, berarti bisa berarti rusak atau driver chipset tidak didukung. Jika rusak atau mati silahkan beli baru, pokoknya ganti dengan yang masih hidup. Untuk mengetahui apakah mati atau driver tdk terdeteck, bisa dicoba pindahkan lancard ke pc lain yang berbeda sistem operasinya, atau bisa juga dengan melihat pada bios. Kalo memang di bios ditunjukkan bahwa lancard tersebut terdeteck, silahkan install manual menggunakan driver yang sesuai dengan sistem operasi, yang biasanya dapat didapatkan di website resmi merek lancard.

Sekian pengalaman saya, jika ada yang mau memberi tambahan atau kritik saran, silahkan. :D
Ayo sama2 belajar...salam..

Tips Atasi Kebiasaan Menunda

Beberapa orang mungkin merasa bersalah dan menyesali diri, karena sadar bahwa menjadi 'si penunda' hanya membuat tugas mereka tidak selesai dengan baik.Sementara sebagian lain merasa terbiasa menunda pekerjaan dan mengaku bisa lebih fokus jika harus berkejaran dengan deadline. Apapun alasannya, menunda pekerjaan adalah kebiasaan buruk yang harus dihentikan. Jika risiko jangka pendeknya adalah hasil kerja yang tidak maksimal, maka risiko lebih besar yang menunggu Anda adalah gangguan kesehatan seperti stress dan migrain. Ikuti langkah-langkah berikut ini dan rasakanlah manfaatnya berhenti menjadi procrastinator!

Bagi Tugas Anda

"Si Penunda" biasa memakai waktu Sistem Kebut Semalam, menyelesaikan segala tugas dengan begadang semalam suntuk. Selain mengganggu jam tidur, melakukan pekerjaan besar seperti membuat essay berlembar-lembar tentu tak mudah dilakukan dalam semalam. Anda butuh membagi tugas, seperti mencicil satu lembar essay setiap hari atau menulis sebanyak mungkin dalam waktu 20 menit secara rutin setiap hari hingga pekerjaan Anda selesai.

Mulai dari Tugas Terberat

Banyak orang justru senang menjauhi tugas yang paling tidak mereka inginkan, padahal itu justru akan memberatkan mereka. Cara terbaik menyelesaikan seluruh pekerjaan adalah dengan mengerjakan yang terberat dan menikmati hari-hari santai selanjutnya dengan tugas yang ringan. Menyelesaikan tugas terberat lebih dulu juga akan membuat hal yang ringan jadi terasa mudah untuk diselesaikan

Buddy and Reward System

Minta rekan kerja atau sahabat untuk memonitor perkembangan kerja Anda. Lalu setelah tugas selesai, beri hadiah untuk diri Anda. Hadiah tersebut bisa hal-hal kecil yang paling Anda sukai atau hal-hal yang jarang Anda lakukan; spa, makan es krim sepuasnya, atau ke bioskop di akhir pekan. Anda juga akan lebih bertanggung jawab terhadap tugas apabila ada orang yang memonitor kinerja Anda. Caranya, berikan daftar tugas yang harus diselesaikan hari ini pada teman dan minta Ia mengecek apakah Anda sudah mencapai target yang ditentukan. Jangan lupa terus memotivasi diri Anda bahwa ada hadiah yang menunggu jika tugas telah selesai.

Mulai Lebih Dulu

Jangan tunggu sampai Anda merasa siap atau termotivasi untuk mulai mengerjakan tugas! Banyak orang justru menemukan motivasi saat mereka telah memulai pekerjaan itu. Misalnya ketika Anda ingin mencari barang hilang kemudian Anda termotivasi untuk membersihkan rumah.Tentu akan lebih efisien jika Anda membersihkan rumah jauh-jauh hari agar kemungkinan barang hilang dapat diminimalisir.

Ingat, menunda pekerjaan hanya akan menambah beban Anda. Jika beban tugas bertambah, tentunya beban pikiran pun juga bertambah dan hal tersebut bisa berdampak pada hasil kerja yang kurang maksimal. Seperti kata pepatah Rusia, "Tidak ada hasil baik dari proses yang terburu-buru."

Celebrating the Open Technology Foundation

Max McLaren, Managing Director for Red Hat Australia and New Zealand

Open source, like any successful business should, relies on open collaboration and transparency as foundations. At Red Hat, our ethos is built on collaboration, as are our development and business models. Collaboration runs deep through our veins and our commitment to collaborating is relentless because it benefits everyone, users, partners and the open source community.

We believe in collaborating for the good of open source, and aspire to drive its adoption around the world in all layers of society.
A recent collaborative initiative is with the Open Technology Foundation (OTF), which recently launched in Australia with strong support from government and industry. Established with support from Carnegie Mellon University and South Australian Government, the OTF is an authoritative peak body for the Australian and New Zealand public sector and is focused on advancing the uptake of open technologies in all layers of Government.

At Red Hat we are convinced that basing our software on open standards and leveraging an open source development model is critical to delivering software that addresses key business requirements including flexibility, cost effectiveness and functionality, without ‘locking’ organisations into a single supplier's technology, or making it prohibitively difficult to integrate with, or migrate to, other suppliers' components.

With that said, we wholeheartedly support the principles of the OTF, especially in terms of identifying and supporting open technology developers and suppliers, and helping to align their solutions to Federal, State and Local Government requirements. A body like the OTF has been a long time coming in this part of the world, and perhaps that is because of the disparate and differing requirements of the various levels of Government, or because up until recent times open technology alternatives have not necessarily been viewed by all as valid options for Government.
Well, that’s no longer the case. While some government bodies, particularly in Brazil and the EU, have long favored open source and open standards, the prominent use of open technologies by the Obama Administration has raised awareness of the benefits of open source by governments around the world.

Australia has definitely felt the knock-on effect. Here, every Government department has a focus on reducing costs and a number of those have conducted budget reviews to identify areas where savings can be maximised. As a result, currently more than 80 departments are utilising open source in an effort to achieve maximum functionality at a substantially lower price.

Beyond the obvious cost benefits, open source is a smart choice for Government departments and agencies because it promotes collaboration through the deployment of standards and openness. Interoperability across various sectors of Government, and a strong adherence to standards, is also another way open source reduces the need to pour money into development and new equipment.

The public sector has certainly not escaped the cloud computing phenomenon and its potential is being investigated in datacentres right across Government. In an open source setting, cloud computing has the capacity to drive out even further costs – even in utility computing – and can reduce datacentre footprints, provide greater reliability and handle disaster recovery. Already, Red Hat is working with Government agencies to establish services within a private Government cloud – delivering all the benefits of cloud computing in a secure setting.

It is certainly our hope that with support from those with the vision and foresight to embrace all that open technologies have to offer, the OTF will be proactive in promoting these sorts of opportunities to Government.

One high profile advocate of open technology is Senator Kate Lundy, who holds the responsibilities of Parliamentary Secretary to the Prime Minister and Parliamentary Secretary for Immigration Affairs. In a recent blog post about the launch of the OTF, the Senator commented “Open technologies, methods and standards all play an important role in the development of sustainable implementation strategies for open data, citizen-centric services and online public engagement.”

I look forward to working with the OTF to continue eliminating confusion and FUD through informing and enlightening.

Knowledge is power, so let’s share it.

India’s Escorts Group embraces IBM Smarter Computing for group wide ERP implementation project

Workload-optimized servers, smarter storage to help company reduce costs by 35 percent

India, - 23 Sep 2011:

The Escorts Group, one of India’s leading engineering conglomerates, is adopting IBM’s (NYSE: IBM) smarter computing approach to information technology. Through an agreement with IBM, Escorts Group will receive a workload-optimized hardware solution to replace the company’s existing ERP system infrastructure. The advanced systems will provide enhanced performance and compliment the company’s business growth goals of lowering overall IT operating costs.

“Escorts Group has embarked on a journey of IT transformation to achieve operational & manufacturing excellence,” said Mr. Vipin Kumar, Group CIO, Escorts Limited. “To achieve this we are not only going beyond adhering to prevailing norms, we are in fact setting our own standards and relentlessly pursuing them to achieve our desired benchmarks of excellence. To aid us in this journey we needed a scalable and high-performing IT infrastructure, backed by a robust technology roadmap. IBM clearly had the best solution, while ensuring a reduction in our energy footprint and increasing return on investment.”

Escorts Group is expanding its current deployment of Oracle Corp.’s Oracle Applications ERP software to cover two new divisions – a utilization increase of about 40 percent.

Setting huawei di centos

Udah nginstall centos, trus udah nginstall paket-paketnya, cuman perlu update. Banyak cara kalo pengen update.
1. Bawa ke warnet, ijin make kabel lannya (cuman jarang yang mau).
2. Make modem rumah - trus config wvdialnya/minicom - cuman kan jarang sekarang yang punya modem serial lagi.
3. Macem-macem cara lain : misalnya make komputer temen yang dijadikan gateway :D

Cuma kita konsentrasi dengan menggunakan modem 3G - Mudah - Murah - Flexible. Kenapa? gak perlu instalasi kabel telepon kerumah, gak perlu bayar abodemen, tinggal beli kartu gsm ama modemnya aja. Pasang dan browse.
Paket-paket 3G banyak rupa : Telkomsel (apn = Internet atau Flash), Indosat dan Excelcom.
kita bahas yang makai 3G - Telkomsel - Flash aja.
List Modem 3G bisa dilihat di bhineka. Tapi perhatikan modem anda bisa jalan di linux atau tidak.
Tulisan ini menggunakan HUAWEI E156G - Black (V) tapi bisa juga untuk HUAWEI E160 - Black (V), bedanya ya di kecepatannya yang satu 7.2 mbps yang satunya lagi cuman 3.6 mbps (tapi toh tergantung dari network operatornya juga - Kalo telkomsel masih make yang hsdpa 2.4 mbps, jadi anda percuma kalau pakai yang 7.2 mbps - kecuali utk keperluan drive test).

Saatnya setting Modem Anda :
1. Cek dulu kernel anda :
# uname -r
Perhatikan jika anda menggunakan kernel seri terbaru maka kernel ini secara otomatis akan mengenali modem usb anda dan mengubah port usbnya menjadi port serial.
2. Pasang modem berserta kartunya (jangan lupa!) dan tunggu sebentar.
3. Cek dengan perintah :
# dmesg
Fungsinya mengetahui posisi USB modem anda ada di /dev/ttyusb0 atau /dev/ttyusb1
4. Buka file /etc/wvdial.conf
# vi /etc/wvdial.conf
kalau masih kosong isikan dengan (ini dengan paket Telkomsel Flash) jika dengan paket internet silahkan ganti di bagian Init3 "flash" menjadi "internet", dan Phone "*99***1# menjadi *99#, untuk meningkatkan kecepatan modem bisa menggunakan Baud = 115200 (perhatikan : makin besar nilai yang anda berikan maka makin besar kecepat yang anda dapatkan, tapi lihat kemampuan modem anda, jika tidak sesuai maka modem anda akan sering mati)

[Dialer Defaults]
Modem Type = Analog Modem
Stupid Mode = yes
Modem = /dev/ttyUSB0
Baud = 460800

Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1, "ip", "flash"

Username = "
Password = "
Phone = *99***1#
ISDN = 0

Perhatikan tanda quote (petik 2 - jangan menggunakan petik 1 2x ), takutnya nanti anda gagal dibagian dialing
5. Jalankan wvdial
#wvdial

Nanti terlihat saat anda menggunakan stupid mode, alamat dnsnya, karena dns ini berubah-ubah tergantung dari setting operator.
buka tab baru, dan edit nameserver di file /etc/resolve.conf
#vi /etc/resolve.conf
Tambahkan line berikut jika masih belum ada
nameserver 114.127.253.84
nameserver 202.3.208.1

press [esc] and save [shift]+z+z
di tab wvdial [ctrl]+c = mengakibatkan koneksi terputus. lalu jalankan wvdial lagi.

6.buka firefox/browser web anda, arahkan ke http://flash.telkomsel.com/halamanutama.php
7.anda siap menggunakan internet.

Kegiatan yang biasa dilakukan di depan komputer

Sembari mengerjakan tugas, sembari melakukan pekerjaan di depan komputer, tak jarang kita juga melakukan kegiatan yang lain. Berikut ini adalah beberapa kegiatan yang sering dilakukan di depan komputer. Data ini hanya menurut survey dan pengalaman dari saya sendiri. :D

1. Makan
Nikmatnya sambil makan atau nyemil di depan komputer. Camilan yang biasa harus ada di meja komputer adalah chiki, roti, wafer, cokelat, dan kacang. Konon ada orang yang beranggapan bahwa, tanpa kacang mata tak bisa terbuka. :D Kalau saya, roti saja cukup.

2. Minum

Minuman yang sering ada di meja komputer adalah kopi. Yup, karena kopi dapat menahan mata kita dari rasa kantuk. Tapi hati-hati!jaga kesehatan.


3. Merokok

Yah...bagi pria, termasuk saya, merokok wajib saat di depan komputer. Selain dapat mengurangi rasa kantuk, juga bisa menambah percaya diri dalam melakukan pekerjaan. Selain itu konon katanya banyak yang mendapat inspirasi setelah merokok.

4. Mendengarkan music
Ini...biasanya cewek yang banyak melakukan ini. Cowok juga tidak sedikit. Karena music adalah warna bagi kehidupan. Dapat mempengaruhi emosi jiwa dan pikiran. Jadi music sangat perlu.

Yah,,,baru itu saja yang dapat saya sebutkan, karena itu yang paling banyak dilakukan orang di depan komputer termasuk saya.

“Halo Dunia” dilihat dari 5 menara

Written By pcbolong on Thursday, September 15, 2011 | 6:49 PM

Saya akan memberikan contoh kode program sederhana dari beberapa bahasa pemrograman yaitu c/c++,perl,java dan c#. Program yang akan saya buat adalah program yang menampilkan “Halo Dunia”.

Perl
Kode program halo dunia untuk perl yaitu sebagai berikut :

#!/usr/bin/perl
print “halo dunia /n”;


Saya menggunakan Padre sebagai IDE untuk membangun program perl. Dibawah ini adalah gambar padre dengan kode program halo dunia.

Lalu jika di execute, atau dengan menekan F5, keluaran yang dihasilkan adalah sebagai berikut :


C/C++
Kode program halo dunia jika ditulis menggunakan c yaitu :

#include
main()
{
printf("Hello World");
}


Sedangkan jika menggunakan c++ sebagai berikut :

#include
using namespace std;
main()
{
cout << "halo dunia";
return 0;
}


C#
Membuat program halo dunia menggunakan bahasa pemrograman c# yaitu sebagai berikut :

class halodunia
{
static public void Main()
{
System.Console.WriteLine ("Halo dunia!!");
}
}


Dibawah ini conntoh tampilan monodevelope (IDE c# for linux) saat menjalankan program halodunia.cs.


Java
Membuat program halodunia menggunakan java adalah sebagai berikut, kode programnya:

class halodunia {
public static void main(String[] args){
System.out.println("Halo dunia!!!");
}
}


Nah, itulah program halodunia yang dibuat menggunakan beberapa bahasa pemrograman. :D semoga berguna. Akan saya lanjutkan lain waktu untuk membuat beberapa program sederhana lagi. :D selamat coding ria
