Automating with Telnet

I have a stupid problem, I have a Bitcoin ASIC called a Hex miner. For some reason every 12 hours the thing slows down from 24GH/sec to 5GH/sec. The only way I have found to solve the problem is to power cycle the controller and the unit itself. This would be a pain since I have it in my basement. However I salvaged some old Bay Technologies PDUs in my rack, which means I can power outlets on and off through a telnet session.

I did a little searching and learned how to do some scripting with the unix program “expect”

This is a very specific script, but it did what I need it to do:

It blazes through resetting the outlets.
