hi, all. I'm a new comer. I asked a question and got an answer in the following link: http://www.fedorafaq.org/#xmms-mp3 Look at No.13, and the answer is below: ****************************************************************************** 13.Q: How do I make XMMS play MP3s? (Updated 23 May 2004) A: Before I talk about this, you should know: In the United States and some other countries, you may have to pay patent royalties to use MP3 players or encoders. However, for home users, there is no legal problem with MP3 players. (Thanks to Doug McClean for clearing that up for me!) With that said, the plugins for these things are usually in the rpm.livna.org repository. 1. Set up your yum.conf to be able to access rpm.livna.org. (See the question about getting Fedora software) 2. Open a Terminal. 3. Become root su - 4. Type yum install xmms-mp3 ****************************************************************************** 2.Q: How do I install software for Fedora? (How to use yum or an RPM) A: The easiest way to install software in Fedora is to use yum. 1. Download this yum.conf. (Updated 29 May 2004) 2. Replace your "/etc/yum.conf" with the one you downloaded. You will need to be root to do that. In fact, you need to be root to do any of the following. Note that the yum.conf provided here is updated from time to time, for various reasons. NOTE: The first time you run yum it will download a small header file for each available package. This can take a long time, sometimes up to an hour, even on a fast connection. Now, you can see a list of the available software: yum list available * To install some software, you type: yum install packagename * To update some software, you type: yum update packagename If you leave out "packagename" yum will update all your software * To see what updates are available, you can do: yum check-update * To search for a package, you can do: yum search For more info about yum, see the yum project page. (Thanks to Ron Kuris for this tip.) If you want more security, I recommend that you un-comment the lines in the yum.conf that start with "gpgcheck=1" -- you might also want to look at the gpg signature question, if you do this. (Thanks to Kai Thomsen for convincing me to add this note.) To get yum through a proxy, see the FedoraForum thread about yum and proxies. (Thanks to Reinhard Herzfeld for that link.) To install an RPM that you downloaded outside of yum, open up a terminal and as root do: rpm -Uvh filename.rpm ****************************************************************************** According the two answers above, I have downloaded the file "yum-2.0.7-1.noarch.rpm" from http://linux.duke.edu/projects/yum/ and executed it. And I have downloaded file "yum.conf" in the answer No.2, and replace my /etc/yum.conf without modifications. Then I did as No.13 said. But I don't understand the step ( Set up your yum.conf to be able to access rpm.livna.org. ) in No.13. The result is listed as following: ****************************************************************************** [root@localhost root]# yum install xmms-mp3 Gathering header information file(s) from server(s) Server: Fedora Core 1 - i386 - Base retrygrab() failed for: http://mirror.clarkson.edu/pub/distributions/fedora/linux/core/1/i386/os/headers/header.info Executing failover method retrygrab() failed for: http://mirrors.usc.edu/pub/linux/fedora/fedora/fedora/1/i386/RPMS.os/headers/header.info Executing failover method Server: Fedora.us Extras (Stable) retrygrab() failed for: http://download.fedora.us/fedora/fedora/1/i386/RPMS.stable/headers/header.info Executing failover method retrygrab() failed for: http://mirrors.kernel.org/fedora.us/fedora/fedora/1/i386/RPMS.stable/headers/header.info Executing failover method retrygrab() failed for: http://fedora.quicknet.nl/fedora/fedora/1/i386/RPMS.stable/headers/header.info Executing failover method retrygrab() failed for: http://mirrors.usc.edu/pub/linux/fedora/fedora/fedora/1/i386/RPMS.stable/headers/header.info Executing failover method retrygrab() failed for: http://fedora.mirror.sdv.fr/fedora/fedora/1/i386/RPMS.stable/headers/header.info Executing failover method failover: out of servers to try Error getting file http://download.fedora.us/fedora/fedora/1/i386/RPMS.stable/headers/header.info [Errno 4] IOError: HTTP Error 404: Not Found [root@localhost root]# ****************************************************************************** Please tell me how to do it. thanks a million.
