You may already be familiar with the feed I put up from Security Focus so you can easily get the latest news on vulnerabilities that are either already out in the wild or have the potential to be soon. If not, check it out here. As I am always looking to improve things, I recently added some feeds that will deliver the latest advisories for Red Hat, SuSE and Ubuntu Linux quickly and easily. So, to recap, from here you can easily get information on the latest vulnerabilities overall, plus the latest advisories for three top Linux distros: Red Hat, SuSE, and Ubuntu. Check ’em out and look for more good stuff, as I find new ways to deliver goodness, I’ll be adding them. Thanks.

Labeling Hard Drives In Linux
Recently I got another external USB hard drive for backing up data. I plugged it in and everything was great except for one thing. The drive came up with the name (label) that Seagate put on there by default. So I was looking a drive mounted at “/media/FreeAgent Drive”, ugh, that sucks. So, I did a little digging and came across this awesome article that covers the many different ways to label your drive. It was interesting that it all basically comes down to your file system, but this article has most everything covered. Check it out …
64-bit Linux Running Google Gears In Firefox
Description and Problem:
Google Gears is a plug-in that extends your browser to create a richer platform for web applications. There are many Web applications that currently make use of Google Gears. Some of these include Google Docs, Google Reader, MySpace, Picasa, Zoho and (the reason for this post) now even WordPress. Google Gears, or simply just Gears as it is now known, not only enables offline browsing of supported sites, but it can also greatly improve the performance of these sites and web applications like WordPress. This makes working with supported web applications much nicer.
Now, my problem (and many others of you out there) has been that I am running 64-bit Ubuntu (8.04 Hardy Heron) and Google has not made a 64-bit version of their Gears software. They cite lack of time and testing resources, but my guess is it’s not that important to them since there probably aren’t too many 64-bit users out there. Luckilly for us, Gears is an open source project. This is now a prime example of the beauty of open source software, in that some really smart people created an “unofficial” patch that allows you to install and run Gears on 64-bit Linux in Firefox. In my case it’s Ubuntu and Firefox 3.x, but I have read folk that have had success with SuSE and others as well. It only took me about five minutes once I found the patch.
Here are the steps I took to get this installed, up and running:
Grab the latest version of the Gears binary that has been patched for 64bit at http://www-personal.umich.edu/~swolchok/gears/, I used this command:
wget http://www-personal.umich.edu/~swolchok/gears/gears-linux-opt-0.4.9.0.xpi
Open Firefox and choose File->Open File and browse to where you saved the file you just downloaded. It should open an install window, you want to press the “Install Now” button to start the install.
Once the install is complete, press the “Restart Firefox” button to restart Firefox and complete the installation.
Summary:
For me, upon the initial restart, I got an error about this addon not being compatible with my architecture. Despite that it seems to work fine, and I haven’t gotten any more errors since then, so I would suggest you simply ignore that error.
Lastly, go to a site that is supported, add it to Gears and enjoy! If you have any questions or comments, post ’em below.
PowerUp Your Shell With Your Profile
How about some neat-o shell tricks for everyone to play with? I figured out some neat things the other day while trying to add some functionality to my shell, specifically through scripts or the profile. What I found was that the magic is in the profile!
Have you ever wanted to have commands that performed certain functions from quick keystrokes rather than long command lines? Of course you have, that’s why we all set aliases in our profiles like ‘ll’ instead of ‘ls -al’ and the like. But what if you want or need more functionality than simple command shortening? That’s what I was after, more function in a smaller form. Some way to pass variables to aliases to get more out of them. Ah, but you can’t pass variables to aliases, so we are stuck right? Wrong, that’s where the functions come in to play.
Best Backup Tool For Budding Networks
One thing I have been doing for many years now, decades even, is backing up and restoring data. It’s easy to backup stuff at home, simply copy your valuable bits and bytes to an external hard drive or write them to a CD-R or DVD-R. This makes backups easy, though a bit cumbersome, especially as hard drives and data requirements get bigger and bigger. Think about all the digital content we have nowadays versus just a few years ago. Movies, music, games and more that get purchased and downloaded right off the net mean more and more gigabytes to backup.

Still though, for saving the critical stuff like documents and pictures, CD’s and DVD’s are OK. But what about when you have more than one computer? With prices falling and computer technology getting more and more prevalent in the home, it’s not un-common for households to have at least two computers in the form of a desktop and laptop. However, I am seeing more and more households with computers for mom and dad, the kids, grandparents and then some laptops on top of all that! Whew! Now we are getting into one major pile of work to try and back all that up.
In the commercial world where you are backing up a data center full of servers and/or cubes laden with workstations, you buy commercial software like Veritas Backup Exec or NetBackup or Arcserve, etc. Throw your data onto tapes inside a robotic tape library and manage it all from one central console. Now, that’s all well and good, but it’s very expensive and doesn’t exactly fit in the average home very well.
So, where does that leave people like me and I am sure many of you out there that still have several computers to backup? We are caught in a kind of in between place. Well, I am going to share some good stuff that I have found, and actually have been very impressed with. Continue reading
apt-get quick reference
For all you Debian and Ubuntu nuts out there, and especially the newbies, there is a nice little apt-get quick reference that has been added to the library. Take a look and get to apt-ing!
