Check to see if you have the following file on your system:


If you do, then just loopback mount the DVD image under /media/cdrom or 
/media/cdrecorder, and then use the yum command as described in that 
repo file:

yum --disablerepo=\* --enablerepo=c4-media [command]

Not sure if that works with "up2date" or not... haven't used up2date in 
a long time...
