Installing software on Linux is actually quite different to how you usually install software on a Windows system.

 

Most Linux distributions use what is known as a 'package management system' (such as RPM or Deb). The package management system is responsible for keeping a list of all the software installed on your Linux computer, knowing which bits of software need other bits of software to run and for preventing different pieces of software interfering with each other.

 

That means that rather than downloading some software as an .exe installer file and running that, as in Windows, the best way to install software on Linux is to go through your package management system so that it can keep everything neat and tidy.

 

To make it easy to find the .rpm and .deb packages you need, most distributions also have a program for automatically finding the right files, downloading them and installing them for you. This is, for example, aptitude (apt-get, apt-remove) on Ubuntu, Debian and many similar distributions and yum on Fedora/RedHat/CentOS-based systems.

 

For example, if you wanted to install the program recordmydesktop (a great program for making screen recordings of what's happening on your computer screen), you could use these commands at a terminal:

 

For Ubuntu/Debian/etc.:

Thinking of giving Linux a try?

 

Entering the world of Linux can be a bit daunting, sometimes simply because of the vast number of choices of different versions of Linux, called distributions (often shortened to 'distro').

 

If you haven't used Linux before and you'd like to just give it a try, one of the best ways to do this is with a Live CD. A Live CD distro allows you to boot your computer from the CD and use Linux without installing it to your hard drive and without making any changes to your computer at all. The disadvantage of a live CD is that it's really best only for experimenting and having a play -- anything you do won't be saved when you restart your computer! Live CDs will also be a lot slower than Linux installed on your hard drive.

 

Ubuntu is a great Live CD distribution to start with. You'll want to download the 'Ubuntu Desktop' file from the Ubuntu download page. The download size is quite large -- you are downloading a whole operating system here!

 

Other good Live CD distributions you can try include Fedora, Linux Mint and PCLinuxOS.

 

Once you have download the .iso file, you need to burn it to CD to make your 'Live CD'. However, you can't just copy the file to a CD normally -- you have to make sure the ISO image is properly unpacked on your CD. ISO Recorder is a good, free program to use for this on Windows, or you may already have CD burning software that can write ISO image files.

 

Once you have used ISO Recorder or another program to burn your new live CD to a disc, you should be able to just reboot your computer with the disc in the drive to start your Linux distribution up. (If that doesn't work, you might need to check your BIOS settings to allow booting from a CD)

 

Now you can have a play with Linux in this Live CD environment, without affecting anything else on your computer. Later on, you can choose to install the distribution to your hard drive if you want to use Linux more often.

Hey Everyone,

 

I'm new to the forums. Been using Linux on and off over the years. But for the past month I've been starting to get more serious and investing more time in Linux. I have mostly used ubuntu but now I'm trying out debian now. I'm also interested in CentOS but since I'm still a Linux noob I think I've come to the write place. :)

I've just been playing around with the new Fedora 13 Beta release in a virtual machine. It looks pretty attractive and seems to work well (in this VM configuration anyway).

 

It ships with the Firefox 3.6 release and there's a new photo management app called Shotwell (which has an 'Events' feature like Apple's iPhoto), but a lot of the other new stuff is under the hood, so I'm not sure what other interesting things there are to see just yet!

Let me know if there's anything specific from F13 beta you want to see, I'll be having a snoop around the new release for a while. :)

The Apache Software Foundation reports that it was hit earlier in April by a sophisticated attack that compromised user passwords.

 

Hackers launched a multistage, targeted attack against the Apache Software Foundation's infrastructure April 5 that compromised user passwords.

 

According to the foundation, the hackers took advantage of an XSS (cross-site scripting) vulnerability using a shortened URL to target the server hosting issue-tracking software for the open-source group's projects. The foundation uses a donated instance of Atlassian JIRA to track issues and requests, and hosted the instance on brutus.apache.org, running Ubuntu Linux 8.04 LTS.

 

"If you are a user of the Apache-hosted JIRA, Bugzilla or Confluence, a hashed copy of your password has been compromised," the foundation said in an April 13 statement on the Apache Infrastructure Team blog. "JIRA and Confluence both use a SHA-512 hash, but without a random salt. We believe the risk to simple passwords based on dictionary words is quite high, and most users should rotate their passwords."

 

The statement continued, "Bugzilla uses [an] SHA-256, including a random salt. The risk for most users is low to moderate, since prebuilt password dictionaries are not effective, but we recommend [that] users should still remove these passwords from use.

The Beta release of Fedora 13 (codename "Goddard") blasts off today, true to its namesake, scientist and liquid-fueled rocketry pioneer Robert Hutchings Goddard. The Fedora 13 Beta release gives an early peek at free and open source technologies that reach new heights of functionality and usability. The Beta milestone is when the Fedora Project encourages users, developers, and administrators of all types to download and try out the release early. While generally the Beta is reasonably stable, this is the time for users to exercise their favorite parts of the system and report any lingering bugs before the final release.

I recently bought a new SATA hdd and have it connected to my fedora 12 box. Since its a raw disk i have no clue of how to use it. It doesn't get mounted on start up and i don't know how to mount it. Can someone guide me how to do following things.

1. Format it to ntfs

2. mount it.

Also I don't have any windows on my box. Any help please....

I installed postfix with dovecot and mysql but I faced some problem...

 

First of all it seems like when I am starting the postfix process it's taking 20%wa ...

 

Than when i'm trying to send message from gmail to my mail box it seem to reach fast to the /var/spool/postfix/incoming/... but it's not coming to the defined mail dir in /home/vmail/domain/mailbox... Until I restart the postfix than it shows up there and it happens again and again, sometimes it reachs without restart but it takes quite long time. It's not problem with the server connection or speed because it arrives the spoll directory very fast so it might have somthing with the postfix process that stuck?

 

Another thing, when I try to send message to someone like gmail.com or other host it says relay host denied , how do I open all relay host? not just few I set manually.

 

Thanks very match!
