In the world of Linux, and computers in general, there’s more than one way to skin a cat. Or so the proverb goes.

Actually on a side note that proverb dates back to 1678 with the second edition of John Ray’s collection of English proverbs. It later came to the states in Mark Twain’s 1889 novel “”A Connecticut Yankee in King Arthur’s Court”". Some have pointed out that rather than a feline the cat in question may referr to a catfish, which is usually skinned before cooking, or the gymnastics performance involving passing ones legs over their arms while hanging from a bar. Either way I should make it clear that here at Hak5 we love cats.

Alright, now with that out of the way, our recent look into hiding passwords from Bash history spurred a furry of feedback, incluidng this tip from Meimi039 who wrote:

To avoid passwords in bash_history use:

export HISTCONTROL=ignorespace

Any command starting with a space wont show up in the history.

Meimi039 goes on to say

You can also do this by setting:
export HISTIGNORE=”"”"pass:wget:ls -ltr:”"”"
Commands containing ‘pass’ or ‘wget’ … will not be added to the history…

Thanks for the tip Meimi. TheOnlyEpsilonAlpha pointed out that if a user were to gain access to your system during that session the password could be retrieved by issuing echo $password. This is true, so to work around be sure to unset the variable with the aptly-named unset command.

Metalhead noted that he used the history -c command out of force of habit when logging out of a session. The -c option clears the history. Alternatively the -d option will delete a specific history entry.

Fisurad0 points out that issuing HISTSIZE=0 will nullify the history completely.

Polokov has a really neat one. Seems if you use the arrow keys to select the previously typed command and issue the shortcut CONTROL+a, CONTROL+a then CONTROL+k it’ll remove the line from the history. Neato!

And finally OverSoft points out that the .bash_history command can simply be deleted. Problem solved!

Open Source Airfoil Design

Pranay Sinha from the Quadshot project joins us to discuss open source airfoil design.

Install Ubuntu from Windows

Interested in Ubuntu but don’t want to commit to partitioning your drive or turning your PC into a Linux machine? There is a really easy way to run it alongside Windows and still get the full OS for both.

Wubi (Windows-based UBuntu Installer) is an official Windows-based free software installer for Ubuntu. Wubi’s goal is to assist a Windows user who isn’t too knowledgeable in Linux in trying Ubuntu without risking any loss of information due to disk formatting or partitioning. Wubi can also uninstall Ubuntu from within Windows kind of like an application or program.

Now you may be thinking that sounds kind of like a virtual machine inside Windows, but it’s not. Wubi creates a disk image that can be run directly from the hardware, no virtual machine needed. It adds a new entry to the boot menu, so a user has the option to run Linux Ubuntu or Windows. In this way, it is a little different from my usual portable apps because you won’t be using GRUB to boot onto the Linux Distro Ubuntu will be installed on the actual Windows file system and Linux will think it’s a real hard disk, giving you the option to boot from it.

It does sound very epic win and super easy, but there are some limitations. Hibernation isn’t supported and hard reboots happen. Also, if you get a BSOD in Windows, you have to reboot Windows, shut it off, then boot your computer again to access the Linux distro as Ubuntu won’t be able to mount the drive successfully until your machine has cleanly rebooted. Performance will be a little slower than a normal Ubuntu install, but not by much. This is because you’re going through the Windows file system to access the Ubuntu distro instead of just booting directly off Ubuntu.

I also wanted to mention that you can have Wubi on a USB drive. There are a couple of other versions of it too- Lubi for Linux, and Mubi for MAC (which is still in the works).

If all this sounds really weird to you, I’m going to do a little step by step of how Wubi works and what it looks like to dual boot into Ubuntu using this program.

From using Wubi, I can tell that this is a really good way for someone to get their feet wet in the world of Ubuntu without having to do the full install. It does make it super easy to get into Linux and it feels like an actual install, specially when you get the option to boot Windows or Ubuntu on the boot up screen. It makes it feel like you’ve installed Ubuntu completely separate from Windows even though from it’s limitations you know thats not the case.

I think this is a really good tool for beginners or just to make life easier for anyone. You can always email me your thoughts at feedback@hak5.org.

The open source screen recorder you couldn’t think of for windows is probably CamStudio Open Source. It is one of the most popular and free recording software. Otherwise you have to pay like $300 for TechSmith’s Camtasia Studio. You can find CamStudio at http://camstudio.org/

freeukvpn.com It’s great with 2mbps bandwidth which is just enough for streaming but they change the password every 12 hours which is a minor inconvenience for such a great service.

Hiren’s BootCD to fix your PC

On the hunt for another bootable CD with lots of fun tools? Here’s one that’s always been a favorite for many. Hiren’s BootCD (HBCD) is a free bootable CD that contains a load of useful tools you can make use of in a variety of situations like analyzing, recovering and fixing your computer even if the primary operating system can not be booted. It features tools that are helpful to partition, backup, recover, and work with the BIOS/CMOS. The website says that this is for people who have problems accessing the downloadable programs that can help them fix their computer. If you have Hiren’s BootCD, you don’t have to download all those programs. You can repair issues like hard drive crashes, viruses, password recovery, and data recovery.

On the website, I started following these crazy directions where you had to download the USB Disk Storage Format program, Grub4DOS, and the newest version of the Hiren’s BootCD. After getting like halfway through, I had a duh moment and figured out since there’s an ISO in the BootCD folder, I’m just going to use UNetBootin and install the ISO onto my USB drive. So I formatted my drive into FAT, and installed the ISO on it.
Now it’s time to boot up and see if it works!

In regards to the install, I guess if you have issues trying to just stick the ISO on the flash drive you can try the How-To on Hiren’s website. They also say:
“”If you are getting GRLDR error, or if usb booting is halting with a blinking dos window, or if you are faced with similar situations, try using syslinux to boot grub4dos. To do that, download syslinux.zip, extract its contents, run ‘RunMe.bat’ inside of the extracted folder and follow its steps.”"

Although this Bootable CD is super cool and easy to use, I do have to mention that some of the tools found on here are not free to use. You have to have a license to legally use them, so you may not want to use it.

That said, I really like Hiren’s bootCD. It’s combination of tools and programs for any kind of recovery is very useful and I’ve been a fan of it for many years. Although Hiren’s is an older tool, it is updated and fixed periodically, with new versions being released all the time.

Today we’re doing a little website mirroring and local web serving. Whether you’re backing up a website, doing some prototyping or simple building a phishing site you’d be hard pressed to find an simpler mirroring tool than HTTrack.

Available for Windows, Mac and Linux this open source, multilingual mirroring tool sports multiple web targets, user selectable recursion levels, resume features and more. It’ll even convert to 8.3 file naming incase you’re still using DOS 6.22.

Getting started is simple. Begin by creating a directory to store the website mirror. I’ll go ahead and mkdir websites in my home directory and move there. mkdir ~/websites and cd !$

Now with our directory make simple issue httrack. Once you get familiar with the tool you can automate the process with flags and such, but the straight forward interactive wizard is much appreciated.

We’ll start by naming our project, then provide a directory to save the files and the URL of your website or websites separated by commas or spaces. Finally we’ll choose how we’d like to download. I prefer option 2, mirroring the web site with the wizard.

Here we can specify if we’re using a proxy, what filetypes we would like, and any additional options. Finally we’re provided with a command line so that next time we can perform the same action without the prompts.

In my case the command would be httrack -W -O /path -%v

Hit Y for Yes and the process will complete in just a moment, or maybe longer depending on the size of the site and how recursive you want to get.

Finally we can see our finished work with ls. You’ll notice HTTrack creates a a log and cache directory and all of the saved files will be found in your website directory.

Now in just a bit we’re going to visit our newly mirrored website from our localhost with a very simple webserver, but first let’s take a quick break.

With our site newly mirrored and the html files sitting happily in our directory we can actually browse to them with a webserver locally in one command. Yes, one command. How happy is that?

Issue python -m SimpleHTTPServer and a webserver will be spawned serving up your current working directory on port 8000. Now we can head over to our web browser and check out http://localhost:8000 to see our finished product.
