Fedora 9: Disable IPv6 Completely

On previous post, I have covered on how to disable IPv6 on older Fedora versions. Considering major and rapid changes with Fedora rpm packages and installation manner, here again a quick post on how to disable IPv6 completely.

Disabling IPv6 protocol is only recommended if your network is not using IPv6 IP addresses and/or you are not offering any IPb6-based host services. I have heard stories about IPv4-based networks making their network a little bit slower than normal when IPv6 IP address is being enabled from their hosts. If you wish to disable your IPv6, read on.

Fedora 9: Disabling IPv6 Protocol Completely

1. Append the below lines to /etc/modprobe.d/modprobe.conf.dist using your favorite text editor

alias ipv6 no
alias net-pf-10 off

IPV6 slows down the IPV4 environment if the router out the door does not understand IPV6 and for most people IPV6 is not needed.

2. Append the below lines to /etc/sysconfig/network


and from the same above file, make sure that you comment out or insert a # (sharp) sign before the word IPV6_DEFAULTGW that would make it look like


3. Edit /etc/hosts and comment out the lines that shows

::1 localhost6.localdomain6 localhost6

to reflect

#::1 localhost6.localdomain6 localhost6

and restart your network service like so

# /sbin/service network restart

4. Save all changes and restart your Fedora box. Welcome to IPv6-less host club.

Fedora 9: All in One Kopete Messenger Installation

I am sure almost everybody of us have heard the linux multi-messenger alternative, that comes with KDE environment. If you have not installed KDE as one of your alternative X logon environment, chances are kopete and its dependency libraries were not installed.

KDE and the Kopete developers had made and improved a lot of messenger's feature and intuitive interface design. One noticeable changes was the usage and management of messenger's avatar images. Avatar images adds up some sweetness to application's taste that believed to spice up little of using the said messenger. Pop up menu interface on choosing messenger identity is also added from its main interface design, which complete removes the standy icon that always sits down at the bottom and right hand side of kopete.

Kopete currently supports more than 11 major messaging system that is currently available on different OS platforms. You get to enjoy these highlights when using kopete messenger. Just a simple account setup is the only thing needed on accounts creation. Account creation simply requires you to feed authentication details into kopete such as login username and password, which is easy from the most part and does not require you to install any modules or external application at all compared to different platforms.

All in all, kopete had made a tremendous improvement on making linux messaging system a much more enjoyable experience.

Now, here's how to install Kopete messenger with Fedora 9 OS.

FEdora 9: Kopete Messenger Installation

The installation is really simple. Launch yum to fetch all the kopete network library modules via yum as shown

HowTo: Install FFMpeg on Fedora Linux

FFMpeg is a complete and free Internet live audio and video broadcasting solution for Linux/Unix. It also includes a digital VCR. FFMpeg can encode in real time in many formats including MPEG1 audio and video, MPEG4, h263, ac3, asf, avi, real, mjpeg, and flash.

FFmpeg can generate a lot of different types of multimedia files with a variety of audio and video codecs inside. Sometimes these formats do not adhere to "accepted" specifications. Many open source multimedia playback applications have been specifically tuned to play all manner of multimedia files, no matter how incomplete or broken. However, certain widespread, proprietary multimedia applications, such as Microsoft Windows Media Player and Apple's QuickTime Player, are a little more rigid in the types of files they will accept.

FFMPEG Fedora Installation

Fedora repo supports FFMpeg. To install, simply issue

# yum -y install ffmpeg

FFMPeg Usage

# ffmpeg -i inputfile.ext outfile.mov
# ffmpeg -i inputfile.ext outfile.mp4
# ffmpeg -i inputfile.ext outfile.mpg

To convert a movie file into a playable AVI file
# ffmpeg -i inputfile.ext -vcodec msmpeg4 -vtag MP43 -acodec mp3 outfile.avi

To use Microsoft MPEG-4v2 video
# ffmpeg -i inputfile.ext -vcodec msmpeg4v2 -acodec mp3 outfile.avi

To create MPEG file with MPEG-1 video and MP2 audio.
# ffmpeg -i inputfile.ext outfile.mpg

To convert FLV to MPG using ffmpeg
# ffmpeg -i inputfile.flv -ab 56 -ar 22050 -b 500 -s 320x240 outputfile.mpg

Yes, you can use MPEG to convert video files from one format to another format, with a different video quality and pass. File output from FFMpeg was also tested to work with Windows Media player, Apple Video Player, Quick Time players and more.

All is done.
