I want to install vnc server in fedora8 (I know its quite old distro). I have setup the VM under Vmware.
I am connected to internet as i can ping google from the console. However if i try to use any yum command it is just hanging and not giving the command prompt again. After a long time it gives the error as

why are the repository not working for fedora 8?

The repositories for Fedora are long dead because Fedora 8 is no longer supported. They are unavailable.

Fedora 8 hit its end of life in 2009. That is why there are no repositories for it.
Install the current Fedora 17.

I have worked on fedora 8 and the repositories worked fine just months back.

not only all of the above
but 8 in particular had an issue

the SECURITY hashes WERE CHANGED!!! ( red hat server break in )

what is on the dvd WILL NOT MATCH what is in the old archives
yum will not be able to check them and toss an error

also YOU MUST use the ancient historical archives non of the mirrors are up for 8
you WILL have to manually point yum to the historical archives
by manually editing the repo file

and MANUALLY find the OLD versions of prerequisites

but if you MUST use 8 and 8 only and NO OTHER
firefox 2 is it
you will NOT be able to run ferefox15

and the version of VLC is going to BE VERY out of date
please see the EOL fedora forum
"EOL (End Of Life) Versions "

but dvd playback is going to be fun libdvdcss for fedora 8 was on livina .And that repo is DEAD

http://kdeforge.unl.edu/mirrors/fedo.../fedora/linux/
notice the "newkey"
http://kdeforge.unl.edu/mirrors/fedo...nux/updates/8/

Edit your '/etc/yum.conf' configuration file and add/modify the following lines:

[base]
name=Fedora 8 - i386 - Base
baseurl=http://archive.fedoraproject.org/pub/archive/fedora/linux/releases/8/Fedora/i386/os/

[updates-released]
name=Fedora 8 - i386 - Released Updates
baseurl=http://archive.fedoraproject.org/pub/archive/fedora/linux/updates/8/i386/

Then, execute the following commands:

yum clean all
yum install vnc

thanks everyone i am able to use yum now. It was a network connection issue.
