I don't know how we got on the subject of proxy servers, in my previous post I said nothing about proxies, the configuration I use is only a cache of packages previously downloaded on the first update. Look at my previous post, based on that configuration when I run yumu on ns1.local.net any packages that need to be updated will be downloaded and installed, for example kernel-2.6.14-1.1656_FC4. When I move to the next machine ns2.local.net and run yumu and it sets kernel-2.6.14-1.1656_FC4 to be updated it will state downloading files, yum then realizes that the file already exists in the cache and the signatures match so it will not be downloaded just pulled from the cache. My setup is not trying to mirror a server, I am just pulling in packages that I need to have for updates. I know that it works, I do it several times a week and packages are only downloaded once and the other 4 machine all use the cached packages.
