Speaking about spdMerlin - it's a good script @Jack Yaz, but you may have to explain "for dummies" how it creates the nice graph. Saturating the ISP line and maxing out the CPU twice per hour by default may hurt today's work/learn from home activities. I've seen some folks run it more often to enjoy the graph. It's one of AMTM scripts created with good intentions, but potentially hurting the user, if the user doesn't know what is he/she doing.
