This post originally ran in May 2008. I am reposting it now, as part of my throwback thursday project, to give some of my older quality posts some love. While I still like Linux and, as I have written about last year still use Linux, it is not my main working platform.
Before starting out with Oracle Linux this summer, my experience with Linux had been more or less confined to Ubuntu, which stems from Debian. Oracle Linux, on the other hand, stems from the Fedora project and Red Hat. Though they both build on the same kernel, they diverge from each other in a few important aspects. Software available in the repositories for Debian are divided into free, non-free and contrib. All software available in Fedora’s repositories are free.
In order to keep the virtual harddrive on my VM as small as possible, I prefer keeping installers on a network share that I can connect to through FTP. The terminal command for connecting to FTP servers handily enough is ftp. When running that command, terminal returned “Command not found”. It turns out that FTP is not installed on Oracle Linux by default.
When first installing Oracle Linux, you may run into being unable to connect to the internet. You may make the mistake of thinking that the problem is with the network settings on the host-side, and try to futz about changing what type of network connection the VM connects to. Don’t bother, it isn’t going to do any good, and you will only get annoyed.
Remember how I said “you should be all set”, last week? Turns out, I was only partially right. After creating a local user account, Linux also configures kdump, the kernel crash dumping mechanism. When attempting to do so, it returned this error message:
I have been wanting to learn more about Linux for some time now, and the time has come to transform a desire to action. I have landed on Oracle Linux, for reasons that will soon become clear. As I don’t have any machine to dedicate to this, and because I want to have the ability to take snapshots and revert to previous states, I will be running Linux as a virtual machine.
One of the things that really annoy me about Linux is the fact that every time I start my computer, I have to enter a separate password to unlock the…
A few weeks ago, I needed to change the password for the Gnome-Keyring, as I wanted to lend my computer to a friend. This can be done using either the command line or through the GUI, the latter being the one I prefer for its simplicity. Here’s how:
Many of you will be familiar of the concept of Linux Live CDs. For those of you who are not, I’ll say this: Most Linux distros are these days installed using a Live CD. You enter the CD into the CD-ROM drive, start the computer, and there you go. Your computer boots from the CD, and your are, effectively running Linux. From there, you can try out the distro, and install it if you want to.
Unetbootin is a program that lets you do the same, only with a USB thumb-drive. The point is that not all computers have a CD-ROM-drive, but most have a USB-port. You simply plug in the thumb-drive, and there you go,
Unetbootin supports the following distributions of Linux and BSD:
Having once again forgotten most of the commands I use in the command shell in Linux in general and Ubuntu especially, I did a quick google search, which turned up this thread at the Ubuntuforums. The thread had two amazingly useful links, both of which referred to quick reference cheat sheets provided by FOSSwire.com Here they are:
