Hi all,
Many thanks in advance. We are investigating Fedora Core right now and one of the concerns is that the FC system will not be connected (or allowed to connect to the internet). All updates will have to be done offline. Is there a central place to check for updates to download for offline installation? Is there a compiled tar file for this anywhere? We are trying to google right now and just thought to ask...if the answer here is RTFM then I'm sorry.

I haven't used rsync and perhaps it does this automatically, but you can also use wget with a list of packages that you have installed, set to only update files that have changed. Point it to a specific mirror that you know is fast and run it every night. You could then burn the resulting changes to a DVD and use sneaker net to put it into the yum cache on the machine you are running in isolated mode. Then you would just run yum update as normal and the updates would occur.

I don't think that the Fedora inrastructure is really set up for this sort of no internet updating. The changes are pushed out to the mirrors over the internet, and the individual installations look over the internet to pull the updates they want.

So no matter what workaround you use, it is going to require internet access for some machine.

You could just set up two identical machines, one on the internet, one off. Set up yum to cache the packages on the machine connected to the internet. Use the cache to burn a DVD. The packages are all signed with a redhat key that would be verified on the offline machine, so you could be sure of getting unadulterated packages. The online machine would just be a dummy for getting the packages. Turn off all services and set up the firewall to be very restrictive. No local data, just the bare installation with all the packages of the offline machine. To be even more paranoid, only boot and check for updates, then shut it down, so you are only on the net for the duration of the package downloads and update.
