Network Administrator’s Resignation Letter

March 30th, 2006 by Niranjan Kunwar

Most probably the funniest resignation letter you’ll ever read. I laughed so loud that everybody was staring at me in office. Enjoy the World’s Best Resignation Letter

You wander around the building all day, shiftlessly seeking fault in others. You have a sharp dressed, useless look about you that may have worked for your interview, but now that you actually have responsibility, you pawn it off on overworked staff, hoping their talent will cover for your glaring ineptitude. In a world of managerial evolution, you are the blue-green algae that everyone else eats and laughs at. Managers like you are a sad proof of the Dilbert principle.

Seeing as this situation is unlikely to change without you getting a full frontal lobotomy reversal, I am forced to tender my resignation; however, I have a few parting thoughts:

Everyone is talking about the new interface that Google is testing. So, I decided to try and can confirm that it’s true. If you want to try for yourself follow this blog’s instruction. This is what I did:

Google mistakenly deletes it’s own blog!

March 29th, 2006 by Niranjan Kunwar

Google blog was unavailable for a short time few days ago and this is what happened:

We’ve determined the cause of tonight’s outage. The blog was mistakenly deleted by us (d’oh!) which allowed the blog address to be temporarily claimed by another user. This was not a hack, and nobody guessed our password. Our bad.

DNS Amplification Attack

March 28th, 2006 by Niranjan Kunwar

Recently a new type of DNS attack have been discovered. Attackers are exploiting the recursive name servers to amplify the DDoS attacks by utilizing IP spoofing. If you want to know the very details of how this attack works then you must read DNS Amplification Attacks (pdf) by Randal Vaughn and Gadi Evron where they analyze 3 real attacks. Also this Cnet news article have some details about the attack.

At the heart of this attack is the recursive function of DNS servers. This is a very serious threat because The Measurement Factory in recent survey found that:

There are an estimated 7.5 million external DNS servers on the public Internet. Over 75% of domain name servers (of roughly 1.3 million sampled) allow recursive name service to arbitrary queriers. This opens a name server to both cache poisoning and attacks.

Here I’ve drawn the diagrams to explain what is Recursive DNS Query and how DNS Amplification Attacks work.

DVD stuck and MacBook Pro opened

March 25th, 2006 by Niranjan Kunwar

A dvd disk got stuck inside the optical drive of MacBook Pro and couldn’t be ejected. I tried to eject it from WinXp, without success. Pressed F12 and Eject button in OSX but the disk wouldn’t come out. The drive was responding with some sound and seemed like it was trying to eject the disk but with no success. So, we opened it and here’s how MacBook Pro looks naked.

The keyboard lifted up

Samba 4 Technology Preview 2 released

March 24th, 2006 by Niranjan Kunwar

Samba 4 Technology Preview 2 is released today. Technology Preview 1 was released on January. Samba is an open source software that allows Unix/Linux system to serve as a file and print server in Windows network. The main feature in Samba 4 is the support for Active Directory logon protocols used in Windows 2000 and above.

The release notes emphasizes that this is a Technology preview to allow users, managers and developers to see how they’ve progressed and to invite feedback and support. They warn that this should not be run on production servers and is not secure.

Samba 4 Technology Preview includes basic Access Control List (ACL) protection on the main user database, but due to time constraints, none on the registry at this stage. We also do not currently have ACLs on the SWAT web-based management tool. This means that Samba 4 Technology Preview is not secure.

OnMac.net site down

March 24th, 2006 by Niranjan Kunwar

I regularly check OnMac.net to see if there’re any updates on video driver for MacBook Pro but from yesterday the site is down. Today morning when I came back to office the site is still not responding. I Googled and found from this blog that there’s some problem with the Apache.

Well, it looks like something has gone wrong again. The server that we’re hosted on is up and running but apache is not. The site went down around 6:00 pm CST 2006-03-22. I’ve only now 8:00 am CST 2006-03-23 been able to get a hold of the guy who can make things happen. I tried to get it fixed last night but was unable. Sorry for the downtime! We’re going to be back up asap.

Update: Good news! The site is up and seems they’d some configuration issue.

We have been experiencing downtime on the main server due to a configuration error. I have alerted the host and created a redirect to this page. When the site is back up, you should be able to go there by clicking the forum, wiki etc… Sorry for the inconvenience - the site should be up shortly
