Measuring speeds

wget. I have a cron job that runs the below script periodically, and a 
logwatch filter that summarizes the min/average/max. It works by pulling 
a file from some ISP that has made said file available specifically for 
bandwidth testing. This obviously tests only download and is limited in 
accuracy due to only downloading from one server.
