I have made some cover with only using my guitar, cables, and open source software such as Guitarix virtual amp and Audacity on my Linux machine. With a little bit effort and no need to big some money to make your own home studio recording. Today, with the increasing of technology in hardware and software, and of course the Internet, we can make our own music studio in your home or even in your room and start to ROCK. 😀 (more…)

I’m running Ubuntu 14.04 on my Asus S550C. I just bought a bluetooth speaker Anker SoundCore Mini. Then I try to connect my bluetooth speaker to my laptop. In fact they’re connected, but no sound comes out from my bluetooth speaker, I’m unable to reproduce any sound from this bluetooth speaker.
I stumble upon from some forums and websites, but did not solve that issue. (more…)

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*)?$

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.

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.

OpenSSL:
According to openssl.org,
“The OpenSSL Project is a collaborative effort to develop a robust, commercial–grade, full–featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. The project is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and develop the OpenSSL toolkit and its related documentation.
