Installing Ethereal on Ubuntu - 12.04

Ethereal is a popular network protocol analyzer, currently known as Wireshark. Wireshark can easily be installed on Ubuntu and the Debian based systems, using, sudo apt-get install wireshark to install, and run wireshark.

However, you can still find the binary packages of the previous versions of Ethereal. The ubuntu/debian package link is broken. But, building from source is pretty easy. Download the source and extract. Move to the root directory of ethereal, and using the below commands, you can simply build and run Ethereal, without much effort.

./configure

Install required dependencies, such as libpcap, that may be missing in your system.
sudo apt-get install libpcap-dev
Make
make
sudo make install

Confirm the installation by running ethereal from terminal.

Lisbon - Week6

Arraial Do Tecnico at IST

[5/10/2012] - So the month of September is completed. Now into a new month.

Quotes from the lecturers!

The lectures are going pretty interesting. Some quotes from the lecturers are really wonderful and deserve sharing here.  

"If you think that way, the rocket to the moon is a glorified firework" - Our Cloud Computing Professor.
"Human nature - That is difficult to understand" and

"Small world, it's difficult to accept as being similar to reality"

- Our Peer-to-Peer Systems professor.
I am enjoying the analogies and thoughts shared by the professors at Instituto Superior Técnico.. ♥

Arraial Do Tecnico

IST by night

We had one of the most famous annual open music concerts of Lisbon, at IST last night and tonight. We enjoyed the music, and broke ice with many other local and exchange students. The night was colourful. We were listening to some nice music from José Malhoa, Dirtyphonics and a few other bands. I am becoming a fan of José Malhoa.

La Isla Bonita.. ♥

Everyone who has been an exchange student surely would have experienced the feeling of missing his country at times. This might have been considered a 'cultural shock,' but it is not. You can still miss your home country, while enjoying your stay at the host country, as an exchange student. Unlike the migration, where you usually migrate to another country with your entire family, an exchange student goes to another country, leaving his or her family and loved ones at the home country. 

The minor things that we did with our family or significant others will be truly missed. In one way, it gives some strong life experiences. Exchange programs are not just learning the course modules. It lets us learn to adopt to a new world, and to value our relationships. I surely had a nice time in Sri Lanka, the beautiful island, and truly miss it, and the memories I had there. It will be one happy day, when I return to my country, with an academic success.

2012

I smiled even during the most challenging times, and made many interesting and tough decisions single-handedly, this year. I am strong in my journey. 2012 is a beautiful year. Smile!

Lisbon - Week5

Radha Krishna Temple, Lisboa

[30/09/2012] August 23rd, 2012 was a Thursday. So my weeks count at Lisboa ends at Wednesdays, and I am supposed to blog on the weekly posts on Thursday, for the past week of Thursday - Wednesday. Anyway, no one is going to assess these posts, and reward me for accuracy. Hence no worries. Here I am blogging for the last 10 days ending with yesterday!

Lectures!

Now the lab sessions have started, and we will get the project descriptions the week starting from tomorrow. We have already completed two weeks of lecture. I will blog about the lectures and how our 3 3-member teams are going ahead with the projects, separately! Ana Milosavljevic and Tamás Balogh are the other two members in my team, and we will surely have some nice projects by end of the semester.

Autumn has begun
We are no more with summer, and it is getting too cold a few nights. Autumn has just arrived! A few of my friends living here didn't forget to scare that winter will be even colder and it will be cold more inside the apartment than outside, at the road!

Templo Radha Krishna

We had a nice time at Comunidade Hindu de Portugal. The temple (Photos) is located at Telheiras, the end of the green line. The temple also has a nice canteen that sells Indian sweets at a reasonable price. The canteen sells lunch too.

Llovizna
With these weekly posts, I can see that blog Llovizna is currently in its third generation. It started in 2008, under my own name ("Kathiravelu Pradeeban") with some random technical entries. By repositioning it under the title "Llovizna," I made my blog to move into its second generation, targeting to address the common reader base of my blog. Recently, with the move to Lisbon, my blog is shaping as more of a travel entries of an exchange student. I can see the difference in the Google advertisements posted on my blog too. Earlier they were almost always about some software. Now they are more about universities, travel and holidays at Europe, and localized content targeting Portuguese. This may be because I am connecting from Portugal, and hence the segmentation. However, I will also keep blogging on the technical aspects, and will maintain the Llovizna-quality in the upcoming posts, that will be useful for the readers.

2013
Just 3 more months for the coming year. 2012 is really going awesome. Vê-lo novamente em breve!

Virtual Credit and Debit Cards..

It was impossible to transfer money to a paypal account in Sri Lanka or India, or transfer money that already exists in the paypal account to a local bank in Sri Lanka or India. Since now I am in Europe, it should be possible. I decided to update the address, and see how it goes.

I learned that changing the country in the paypal account is impossible, and we just have to create a new account with the new address, new credit/debit card, and new phone number, dropping the old account. So now I need Portugal credit card. The debit card I got from BPI for my current account was a temporary card, and it doesn't hold those three digit security code. That simply means, I can't use it online.

Then my friend Dipesh introduced me to the Virtual Debit Card. I was able to buy it from the near by ATM and activate it from the MB web site. The card will have a valid period of either a year, or till your card expires, whichever that comes first. Now, I can buy stuff online using this virtual card, and I also linked it to my paypal account.

I find these virtual cards interesting, just like the VMWare that runs on top of the host operating system, and is capable of running multiple guest operating systems on top of it.

Lisbon - Week4

Instituto Superior Tecnico - Taguspark Campus

[21/09/2012] Yesterday, it was exactly one month since I left Sri Lanka. I flew to New Delhi on the 20th of August, with a transit of 3 days, and reached Lisbon the 23rd. That also means, I am marking my first month at Lisbon the day after tomorrow. The world is however highly connected. Thanks to the Internet, Skype, and Facebook, I am tightly connected to Sri Lanka.

Taguspark 

An IST shuttle service connects Taguspark - Oeiras campus with the Alameda - Lisbon campus, which is otherwise, poorly connected to Lisbon. Taguspark is a science and technology park, full of major companies and industries. It seems the easiest way to reach to Tagus Park through public transport is through the bus route 15, which is infrequent. Hence we have to be careful not to miss the shuttle. Taguspark area is closer to beach, where the shuttle often takes the route through the scenic road adjacent to the beach and the Tagus river.

Lectures!

Lectures are going pretty interesting. We have formed 3 groups of 3 consisting of the 9 EMDC students for the lab sessions and projects, for all 4 modules. Apart from the Erasmus Mundus students, some local masters students as well as the Erasmus Students too join our lectures. Lab sessions will commence starting from next week.

Integrity Aristotle

I recently joined Elance, and wanted to verify my profile. They scheduled a skype video for integrity verification with Integrity Aristotle, which is a global id, and age verification service provided by Aristotle. I was not aware of the existence of such service before, and it was a nice learning experience for me. The service called me on the scheduled interview time, just to take a quick photo through the video chat. Within a few minutes, my Elance profile got a "verified" badge. Sounds interesting. Isn't it?

Our lectures have begun, and chances are high that these weekly posts getting shrunk. Vamos esperar e ver. :-)
