Yum is a software updater installed by default in Fedora. It manages rpm packages. There is a lot of good software built for Feodra out there, but much of it is in 3rd party repositories. This howto will show you how to get at it.
Yum's configuration file is /etc/yum.conf. It is recommended you replace it with this yum.conf because it has more software and more mirrors.
Each software site has an entry with a name and one or more URLs, like
Code:
[freshrpms]
name=Fedora Linux $releasever - $basearch - freshrpms
baseurl=http://ayo.freshrpms.net/fedora/linux/$releasever/$basearch/freshrpms
This is the freshrpms entry. Just uncomment it by removing the #s in front of the lines, and you can get freshrpms.
Whenever you are told to add somthing to your yum.conf, either uncomment it if you have it or add the entry to the end.
I recommend you only uncomment those entries marked "stable" or at least avoid the "unstable" and "testing" ones.
Now we can get some software. Just use
Code:
yum install mplayer
to get the mplayer media player.
