Relaxation unleashed!

-

Days of hard work seem to be over…or not quite…may be…
Graduation was wonderful and so were the trips with daddu and bhabhi to San Diego, Las Vegas and Grand Canyon and not to forget the shopping sprees at Barstow (I-40 exit at Lenwood Blvd.) and Citadel mall, Los Angeles.
Then came the trip to New York City which was as always very welcome!
Met up with Ankush at NYC working at Citigroup office at Long Island City. Now comes the time to unleash my sloth-like wrath towards summer!

9 hrs…still capturing packets!

-

9 hrs down the line I’m still capturing packets, now comes the challenging part-to make the hash tables of raw data! My Rabin’s hash algo seems to be working but the only hiccup that could happen was when the negative hash values are obtained. I don’t know whether it is a bug in my code or what but I got negative values for Rabin’s Hash when I gave the string “this is test”! This is gonna test me for sure.

Projects…interjects!

-

Come end of semester and the project deadlines start impending! The situation I am in is one of great thrill and rush! For the CS558L I’m doing this project in which I have to implement an automated worm fingerprinting mechanism but not only that combining it with ITrace I want to make Worm attacks and DDoS attacks a thing of past!
The scheme in plain English is to detect automatically if your network is being attacked by looking at the traffic and if so communicate this information to whoever you are forwarding this packet to! The ICMP messages that will be forwarded will carry information about who sent this traffic and other such information (including the signature of attack traffic). The receiver with all this information could gather the source of attacks. If all the routers followed this scheme then we will be able to reconstruct the entire path of the attack so the entry point of the attack could also be sealed….(hopefully leading to a Worm and DDoS attack-free internet)!!!
Really hopeful…aren’t I??? 😉
But again this technique has the same single flaw as the other techniques in that it needs co-operation between ISPs.
I am currently coding this scheme in the Linux Kernel 2.6.11.7 and this is my first tryst with linux kernel programming…let’s see what future holds for me!

Nutch failed …presentation succeeded!

-

Finally, the CSCI 599 course on Search Engines concluded. The presentation went off pretty well.
The worst part was that an effort of 5 straight days went down the drain trying to go through the Nutch code. I think the Nutch developer community needs to get a little more matured and help newbies like me else new people would not join the movement! Eventually, I had to make my own focused crawler, query interface web data crawled and query interface.
I also got my CSCi558L scores which were ok…94,99,100 so things look ok so far but now the main effort is just starting off to get the Worm fingerprinting with ITrace going. Let’s hope things turn off well.

Start the Blog!

Just started blogging…actually getting pretty late into the blogging culture! Studying and doing projects to complete graduation at USC. My homepage is at http://www-scf.usc.edu/~swarup/.
