A bad day

Filed under: Studies — acidborg @ 21:14

Today has been one of those days in which you shouldn’t have waken up. At morning, I arrived to the campus one hour late because of an incredible underground breakdown (In Spanish).

Then, we had problems testing OpenVPN in our IPv6 simulation due to some problems with the TUN/TAP device and afterwards with the certificates and cryptographic keys.

After that, I realized that a database conversion from Access to MySQL which a classmate had done didn’t fit the practice.

Last but not least, the meeting for the Final Project for my major wasn’t what I had expected it to be. There were (and there still are) many disagreements among the memebers of the team, so It hasn’t been as fruitful as it should have.

Maybe it’s time to go to bed and sleep instead of keep on working on things…


Last day of 2006 at the university

Filed under: Studies — acidborg @ 22:07

Today is the last day of this year I’m attending university classes. Tomorrow there will be classes too, but it’s the day that university students go party everywhere. “Botellรณn” it’s the most common party here, but there are indoor parties too.

Today’s most important fact is that we have had a Final Project meeting and we’re making progress, slowly but firmly. I just hope that Xmas holidays won’t be as unproductive as last year…


DNS dual stack and Router Advertisement

Filed under: Studies, SysAdmin — acidborg @ 20:24

I haven’t blogged this week because I’ve been busy with many things. We have managed to get BIND to work dual stack, it is to said, with IPv4 and IPv6 addresses. This wasn’t difficult, but it was a bit confusing the way BIND reads IPv6 addresses.

We managed to configure router advertisement as well with radvd. This was harder because we were advertising IPv4-compatible addresses (::IPv4 type) and that wasn’t allowed. It seems that it only advertises global scope /64 addresses, but I’m not sure if this is right or we are doing it wrong. More on this on future posts…

On Saturday, I’m driving to Santiago to visit my family & friends. Next Christmas I won’t go there, so I’m going 9 days now instead ๐Ÿ™‚

I’m not going to blog for 10 days, so please be patient ๐Ÿ˜› .See you soon!


We’re on the right way :-)

Today we managed to make the DNS server (BIND 9) and the Apache web server run in our network simulation. YEAH!!!

It seems trivial, but it isn’t. Next targets are mail server and OpenVPN. Yes,we are on the right way…

Last but not least, I have learned today that fixing GTK-Perl code on an unmaintained CVS is NOT easy.


Visiting the UCM’s Data Processing Center

Filed under: Studies — acidborg @ 13:32

Yesterday, as part of my Final Project for my major, we went to the UCM’s Data Processing Center to ask some questions about the UCM’s network. People there were very nice and considerate. They answered all our questions and even gave us more information than we expected, so we are very happy with the results of the visit.

Apart from that, they showed us their facilities. Personally, I got impressed with the supercomputers they have running there. We entered the room where all supercomputers and routing machines are. It’s very cold there because of the cooling needed. They also have different alarms with sensors for floods, fire, temperature and intrusion. The routing machines were huge wardrobes with thousands of wires connected. They even have a Google’s indexer machine there ๐Ÿ™‚

I hope they will help us with our project giving us more information about the UCM’s network so that we can simulate it and test the IPv6 migration in the simulation process.


First post about the Final Project for my major

Filed under: Studies — acidborg @ 02:12

Holidays ended unexpectedly and now it’s time to look beyond the summer. I’ve started the Final Project for my major or “Proyecto Final de Carrera (PFC)” here in Spain. It consist of the migration of the Complutense‘s computer network from IPv4 to IPv6. It’s a 3-people project, so I hope we will do a great job.

I don’t know the limitations of the project yet, because it will be mainly theoretical, but I hope we will be able to set up some LANs to test all the stuff we document.

I will explain more about the project as soon as the limitations are set and the task are distributed.

Well, tomorrow I’m going to Santiago de Compostela by train (a 7,5 hours journey). Maybe I will make the most of the journey and I will finish reading the book I’m using to learn how IPv6 works for my dissertation:

IPv6 essentials

I will return by the end of this month and I will start working on my dissertation. I don’t know if I will be able to connect to the Internet, so if anyone wants to get in touch with me, just make me a phone call ๐Ÿ˜‰

See you soon and enjoy the summer.
