In this section, we will share with you how to install multiple Odoo, in this case we use Odoo 10 and Odoo 9, instances on a single Ubuntu 16.04 using a python virtual environment. This guide should work on other Linux VPS systems as well but was tested and written for an Ubuntu 16.04 VPS. But if you want to do in your local Ubuntu machine, you can skip step 1.

[SOLVED] fail2ban and denyhosts constantly ban me

March 22, 2014

Banned

Installing and using fail2ban is a great way to prevent attacks on SSH but I encountered an unusual problem with it: I sometimes got banned after frequent successful ssh logins. The reason was that I had public key authentication set up for another user on the same host and ssh was trying to use it for all the other accounts before prompting me for a password. The default fail2ban filters consider the “Failed publickey” error in the sshd log file at the same level with a failed password login hence the ban.

To change this behavior I had to edit /etc/fail2ban/filter.d/sshd.conf and change.

^%(__prefix_line)sFailed (?:password|publickey) for .* from (?: port \d*)?(?: ssh\d*)?$

into

^%(__prefix_line)sFailed password for .* from (?: port \d*)?(?: ssh\d*)?$

Solved : Problem and Step-by-Step Installing NS-2.34 On Ubuntu 12.04 LTS

July 11, 2012

A few days ago, I installed my new PC in my lab with Ubuntu 12.04 LTS. I used to work with Ubuntu 10.04 LTS, but now I want to try Ubuntu 12.04. For my research purpose, I need to install Network Simulation NS-2 on it. As usual everything is not that easy while you’re going to work with Open Source or freeware…hehehe. That’s the challenges in Open Source. I like it.

Implementasi dan Analisis Kualitas Layanan VoIP Pada Jaringan Ad hoc Peer-to-Peer

April 15, 2012

Tri Angga Bagus Susanto1, Abdusy Syarif2, Abdi Wahab3

ABSTRAKS
Teknologi VoIP (Voice over Internet Protocol) adalah sebuah teknologi komunikasi data yang sangat memungkinkan percakapan suara dengan memanfaatkan media jaringan komputer atau jaringan paket Internet Protocol (IP). Pada umumnya, implementasi VoIP menggunakan jaringan Local Area Network (LAN) atau Wireless Local Area Network (WLAN) atau juga Intranet / Internet. Singkatnya, dibutuhkan sebuah infrastruktur untuk dapat mengimplementasikan VoIP. Namun pada penelitian ini akan digunakan jaringan ad hoc peer-to-peer dan akan dilakukan pengukuran serta analisis terhadap kualitas layanan VoIP. Jaringan Ad hoc peer-to-peer adalah sebuah metode yang memungkinkan bagi perangkat keras nirkabel untuk berkomunikasi secara langsung dengan yang lainnya tanpa ketersediaan infrastruktur jaringan. Dalam skenario pengujian digunakan beberapa perangkat keras (seperti laptop, komputer dan telepon seluler), sistem operasi (Windows, Linux Ubuntu, dan Android) dan perangkat lunak softphone yang berbeda (seperti 3Cxphone, Ekiga, Qutecom, Sjphone, X-lite). Dari hasil penelitian dapat dilihat bahwa teknologi VoIP dapat diimplementasikan walaupun tanpa dukungan infrastruktur, yaitu dengan memanfaatkan jaringan Ad Hoc peer-to-peer. Dari hasil pengukuran dan analisa beberapa parameter yang diamati, didapatkan hasil untuk rata-rata delay adalah sebesar 20,54 millidetik, dan throughput sebesar 0,081 Mega Byte/detik, sedangkan banyaknya paket per-detik adalah 94,3842 paket.

Kata Kunci: voip, ad hoc, peer-to-peer

Insya’Allah paper ini akan dipresentasikan pada Seminat Nasional SNATI 2012 di UII-Yogyakarta pada tanggal 15-16 Juni 2012.

Sharing Internet Connection using ppp0

August 20, 2011

I have a usb modem with internet connection. And I need to share its connection to my PC Desktop. So, here is my experiment howto share internet connection via ppp0.

My laptop is using Ubuntu 11.04 with 2 connections: ppp0 and Eth0. My PC Desktop is connected to my laptop using cross-cable with Eth0. I use static IP address for both Eth0.
To share ppp0 connection, I just need install ‘firestarter’ in my laptop.

~$ sudo apt-get install firestarter

Then configure ‘firestarter’ to select the device which connected to internet and enabled the internet connection sharing.
