http://unix.stackexchange.com – I have a PC and a laptop. my laptop is always updated, so for updating the PC I don't want to download the packages again for my PC. What I do is copying rpm files from /var/cache/yum/i386/17/fedora/updates/packages to the corresponding directory of the PC. Is there a better/faster way to do this? can I say yum connect with ssh to laptop and get updated packages from there? (HowTos)
