[FR] openSUSE Conference 2019 – Nuremberg Germany

Before Conference

After an 18-hour flight from Jakarta, Mr. Edwin and I finally arrived at Nuremberg. It is the city of SUSE’s office. We arrived at Nuremberg Airport around 10.00 AM. At first, I thought the immigration checking process would be quite intimidating. Turned out, I was being too paranoid 😀 The questions asked were standard one, such as what’s the occasion coming here, where do you stay and for how long.

Afterward, we bought tickets at a kiosk machine with destination to Lange Zeile, the place where we rent an apartment.

We reached the apartment with no hassle. After some rest, we went directly to the openSUSE Conference 2019 venue at Z-Bau. There weren’t many people around yet.

But we managed to meet with Katrin Murr and Douglas DeMaio, chit-chat for a while and did some helping around.

Before returning to the apartment, we tried to find the nearest mosque to the venue for our Friday prayer. Fortunately, we found it. It is called the Nuremberg Central Mosque. Felt content, we walked back to the apartment, took some rest and waited for the time for our breakfasting, which was around 09.53 PM.

Did I forget to mention that this event was held on the same month with our holy month Ramadan? Yups, we were fasting and it was my first experience having my fasting for more than 14 hours. 🙂

Day1 Conference

Arrived at the location we immediately queued to re-register and take merchandise. at the registration desk I was offered to take a special edition T-shirt or Bag openSUSE Conference. finally I chose T-shirt.

Mengamankan SSH dengan Google Authenticator – openSUSE Leap 15

Bagi saya, akses SSH ke Jump server, Jump host atau Jumpbox menggunakan Public Key adalah mandatori, kali ini saya akan menambahkan Multi-factor Authentication (MFA) untuk akses SSH ke Jump server saya. Berikut langkah-langkahnya:

1. Pasang Repositori

2. Pasang paket Google Authenticator

3. Jalankan Google Authenticator

Scan barcode atau masukan Your new secret key ke aplikasi Google Authenticator

4. Sunting berkas Konfigurasi SSH

5. Disable common-auth dan tambahkan auth google

6. Muat ulang layanan SSH

7. Ujicoba SSH ke Jump server

Sekarang kalian akan dimintai kode Google Authenticator setiap kali Anda mencoba masuk melalui SSH.

Sekian dan Terima kasih

Pasang VirtualBMC (IPMI) untuk Lab TripleO

Sebenarnya ada beberapa cara untuk memasang VirtualBMC cara termudah ialah menggunakan pip install atau bisa juga pasang manual langsung dari sumbernya di git.

Hypervisor
openSUSE 42.3 + KVM (10.2.2.1)

Pasang python-pip dan virtualbmc

Periksa nama VM overcloud yang akan di kontrol oleh VM undercloud dengan perintah IPMI

Tambahkan vbmc ke VM, defaultnya IPMI menggunakan port 623, kalian juga bisa menggunakan opsi -p/–port jika ingin menggunakan port yang berbeda

Jalankan vbmc di host

Verifikasi, pastikan statusnya running

VM Undercloud
Cek konektifias ke node overcloud menggunakan perintah ipmitool:

TripleO
Register node overcloud di UI TripleO


Lalu masukan NIC MAC Addresses dibagian bawah dan klik Register Nodes.

Troubleshooting:
1. Error: Unable to establish IPMI v2 / RMCP+ session
Pastikan port yang dipakai di vbmc di allow di firewall

2. Exception TypeError: “‘NoneType’ object is not callable” in ignored
Error ini bisa diabaikan saja.


Refrensi:  Virtual BMC TripleO Documentation

Konfigurasi VLAN Tagging dengan IP Command

Membuat VLAN tagging di interface virbr1 dengan nama dan ID VLAN 100

Verifikasi

Menambahkan IP ke interface VLAN

Verifikasi

Hapus VLAN

Catatan: VLAN yang dibuat dengan ip command akan hilang jika sistem shutdown atau restart, jika ingin membuatnya permanen gunakan ifcfg files


Refrensi: 7.4. Configure 802.1Q VLAN Tagging Using the Command Line

[FR] openSUSE Asia Summit 2017 – Tokyo Japan

openSUSE.Asia Summit 2017 Tokyo, Japan
This event at Tokyo is the fourth in openSUSE.Asia Summit.
I become excited to take part in this event, when I heard that Japan has been chosen as the host. One of the ways to take part is by submitting a paper.

Not long after, I got the news that my paper was accepted. Yeay, finally I can go to Japan. Along with my friends who also got accepted too, we bought and prepared all the things needed.

Three day before the actual main event, with three of my friends from GNU/Linux Bogor, we left from Jakarta to Tokyo by ANA (All Nippon Airways). The journey to Tokyo took around 7 hours (3,596 Miles)

The first day arrived in Tokyo, I was very surprised by the weather. It was around 10°C. Me and my friend Kukuh, only got time to go around Shibuya and see Hachiko statue. After that, we went directly to our place of stay.

The second day, we went out around noon and decided to visit the Fujiko F Fujio Museum. After that, at night we came to the welcome party held by the committee at UEC (University of Electro Communications).
