I am using VirtualBox with Ubuntu 12.04 as the host and CentOS 6.3 as the guest OS. apt-cacher-ng is configured on the host OS for caching the packages.
I did a bit of googling, but could not figure out how to cache the CentOS guest packages on the Ubuntu host using apt-cacher-ng. How to configure this?
Also, what is the preferred approach to cache the packages in CentOS?
