Yet another off-topic post. Lately I am not doing a lot of radio. However, I think that the occasional experience with IT can be at least as much fun as good ole ham radio.
One of the last experiments was virtualization using proxmox on an AMD E-350 low power dual core processor. This particular system is now equipped with an additional ethernet card (100Mbps) and serves as a firewall w/ caching web-proxy using Smoothwall Express 3.1 RC1. The hardware I use is a total overkill: 8GB RAM and 250GB HDD space. As I said, it was used for experiments with virtualization.
The surfing experience has improved a lot since static features of webpages are now locally stored in the caching proxy.
Using smoothwall with squid is highly recommended!
