I just visited the Ubuntu Forums and bumped into a post I found very amusing. It’s from an individual who believes he’s found a vulnerability in dev/null.
“…I first came upon it, when I was writing an email, and I saved the file at the location /dev/null. Upon logging in again, I found that the file has mysteriously vanished. This was very sensitive information, so I even encrypted it. But this seem like a vulnerability in the Linux kernel, that non root users have access to delete and modify /dev/null as it is the only possible explanation for my file disappearing…” Ha ha ha… Of course it’s gone! 
Maybe you’ll all think I’m a bit crazy, but I thought it funny. Maybe I am a bit nuts!
For users no familiar with /dev/null, it Read the full post…
I was reading a story on Digg this morning, about an 11 year old child who was functioning as the network manager for some private school’s network. Within the comments was a post that referred to “Untangle” and why the school chose not to use it. The commenter suggested that the individual probably didn’t know how to configure the application suite, and that’s why it was not used. The Untangle web site however, says:
“…if you have a basic knowledge of networking, you can install, use and maintain Untangle. With just a few steps, you can transform a rack of servers into one single point of control. And it works from the Read the full post…
Over the week I received a couple messages asking about VMware installations. While I’m sure there are all sorts of tutorials about this, I thought (since I received questions) that a quick “How to” guide would be helpful to some of you.
What is VMware? It’s a virtual environment that lets you install “guest” operating systems. Such as Windows, BSD, other Linux distributions, etc.
Why would you want to use VMware? To facilitate an endless number of OS environments without having to repartition your hard drive. In my case, it allows me to keep my “good installation” (the one I use day-to-day) from my play area where I experiment. For people who want or require a Windows environment, this would be a great solution!
Prior to installing VMware, we need to ensure a few things.
- This quick guide is for Ubuntu Linux 7.10 (Gutsy).
- Patch Ubuntu Linux 7.10, if you’re using source to install (because the first time I did this it failed, and I Googled to find that we had to Read the full post…
Earlier this month I posted about the lack of a simple network management interface for Ubuntu Linux, where I suggested Ubuntu Needs to Improve the Network Management GUI! At that time several readers sent input and others provided helpful comments. Among them was Wicd. Well.. I’ve finally installed it. Wow, was I missing out on a good suggestion. I feel like such a goof for not installing it sooner.
For those not familiar:
“…Wicd is an open source wired and wireless network manager for Linux which aims to provide a simple interface to connect to networks with a wide variety of settings…“, as stated in their sourceforge profile.
Among some of the features I think especially nice are Read the full post…
Quick post!… For those who have not heard yet:
“…The support period is now nearing its end and Ubuntu 6.10 will reach end of life on Friday April 25th, 2008. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 6.10…”
The above was recently announced here: ‘End of Life’ announcement for Ubuntu 6.10
If you’ve not done so yet, it may be a good idea to upgrade your Ubuntu Linux version. Not sure how to do that? There’s a handy guide here: Upgrading to Ubuntu 7.10
Easy as pie!
