Fedora n00b -- having problems with yum, commands

[jbrown96]

I've been using Ubuntu for about a year, and I've decided to branch out. I installed the Fedora beta a couple days ago, and I really like it. My wireless network connection (802.1x University network) actually works, so I think I might be switching for good. However, I have a few questions.

Could anyone point me towards a good guide that could help me adapt quicker, so I don't have to ask tons of questions here, particularly about YUM?
I have been trying to run some basic networking commands (iwconfig, ifconfig), and I get error messages, saying that the commands don't exist. Is this a problem with the beta, different way of running commands on Fedora, or something else?
Finally, I can't seem to install any software. System --> Administration --> Add/Remove Software doesn't seem to have any packages available. Furthermore, if I try to change the sources, there are errors about the source being incorrectly configured. Again, beta problems, or am I too dense to figure out what's going on?

I really appreciate all the help

try /sbin/iwconfig and /sbin/iwconfig. make sure that you are root. do 'man yum' to get your yum commands.

You may also want to have a quick read through here as well.

Thanks a lot all. I think I have yum and the commands figured out.
About the sources? I can't install anything with Add/Remove software or yum. I'm posting a couple of screenshots to show what happens. I have the following sources added (I get errors if I try to add more):
Fedora 8.93 - Source
Fedora 8.93 - x86_64
Fedora - Rawhide

yum
[root@doodle ~]# yum install powertop
Loaded plugins: refresh-packagekit removing mirrorlist with no valid mirrors: //var/cache/yum/fedora/mirrorlist.txt Error: Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again

add/remove software
Unknown error

Hi Jbrown,

There is some very good information out there. I usually usually point people to :

http://www.fedorafaq.org/
http://www.mjmwired.net/resources/mjm-fedora-f8.html

Both of which refer to Fedora 8. You'll need set up the livna-devel repository to get proprietary modules and updates, codecs, video drivers, etc. The faq's cover it, although I believe the following do the job quickly as well.

;; "Adding the livna repository"
rpm -hiv http://rpm.livna.org/livna-release-8.rpm

;; "Disable the standard repo by setting enabled=0"
vi /etc/yum.repos.d/livna.repo

;; "Enable the development repo by settinge enabled=1"
vi /etc/yum.repos.d/livna-devel.repo

There are also repositories at atrpms and freshrpms, but for some reason these are not intercompatible and you can't have more than enabled at one time. There is a project working on it, though (rpm fusion)

Good luck!

That works perfectly! Couldn't understand why standard repositories aren't working. It was pretty annoying since yum isn't downloading and updating anything, hope they solve this problem before a full release.
