Worth Reading: Government lawyers don’t understand the internet

Last year, the FBI nearly destroyed the life of an innocent physicist. In May 2015, agents arrested Xi Xiaoxing, the chairman of Temple University’s physics department, and charged that he was sneaking Chinese scientists details about a piece of restricted research equipment known as a “pocket heater.” An illustrious career seemed suddenly to implode. A few months later, though, the Justice Department dropped all the charges and made an embarrassing admission: It hadn’t actually understood Xi’s work. After defense experts examined his supposed “leaks,” they pointed out that what he’d shared with Chinese colleagues wasn’t a restricted engineering design but in fact a schematic for an altogether different type of device. —Washington Post

IDG Contributor Network: Many people abandon security, risky behavior surges

People are sick and tired of being told to be more secure in their use of computers and when participating in online activities. So much so that they’re simply ignoring the blitz of annoying demands and are carrying on as imprudently as they’ve always done, according to National Institute of Standards and Technology (NIST) researchers.The U.S. Department of Commerce-operated lab recently published a report (subscription) on the subject in IEEE’s IT Professional Journal.The study’s participants “expressed a sense of resignation and loss of control” when the scientists asked them about their online activity, such as shopping and banking.To read this article in full or to leave a comment, please click here

Happy 25th once again to Linux, ‘the little OS that definitely could’

Aug. 25 may be Linux's official birthday, but Oct. 5 is in many ways the day it began to make a real mark on the world. That's when Linux creator Linus Torvalds officially released the first Linux kernel into the wild."As I mentioned a month(?) ago, I'm working on a free version of a minix-lookalike for AT-386 computers," Torvalds wrote in a newsgroup post on Oct. 5, 1991. "It has finally reached the stage where it's even usable (though may not be depending on what you want), and I am willing to put out the sources for wider distribution."To read this article in full or to leave a comment, please click here

Hacking DRBL Client PXE Boot Password

In a previous tutorial I showed installation of Clonezilla Server Edition on Ubuntu using my own Bash script. We configured PXE (Pre eXecution Environment)) password for clients so when the clients booted a password had to be entered to startup. This tutorial explains two different ways how to get and crack the PXE boot password.

picture1_pxe_drbl-_client_password_required

Picture 1 - Client Requires to Enter PXE Password During Startup

First, we should mention some facts. The PXE client password is stored in plain text in a configuration file /etc/drbl/drblpush.conf. The password is secretpassword and it can be found in a dictionary rockyout.txt.

Picture 2 - Plain Text PXE Client Boot Password

The same PXE client password is stored as a hash in a file /tftpboot/nbi_img/prelinux.cfg/default.

picture3_pxe_boot_password_hash

Picture 3 - PXE Client Boot SHA-1 Base64 Encoded Salted Hash

The hash is created by utility /usr/sbin/sha1pass on DRBL server. It is a Perl script which takes two arguments from STDIN - a password and salt and it creates SHA-1 base64 salted hash.

Picture 4 - Perl Script fo Generating Hash from Password and Salt

Explanation:

  • $4$ - SHA-1 base64 encoded salted hash
  • 2mNryVVj - salt

The ever expanding menu…

A short note reminding the gentle readers who wander in to this site of the riches of information available in the main menu to the left of this post…

rule 11 reader takes you to a subscription form for the mailing list. The format and frequency of the mailing list is a little messed up right now, and I always mean to do more with it, but never seem to get around to it.

culture-eats-technologysixty books takes you to a list of books I’ve found particularly helpful or useful over the years. The title isn’t the number of books, strictly speaking, but rather a challenge to read sixty books this year. Not all of these are related to network engineering.

worth visiting is something of a blog role and interesting sites, not all related to network engineering.

author page takes you to a page listing all of my works. Right now this is on Amazon, but as not all my works are available on Amazon, I need to fix this. Yes, it’s already on my list of things to do.
