# Hey coops.. 
# 
# Imagine yourself on the other side of the table: two job openings, hundreds of resumes, 
# _all of which_ look friggin' identical. Yeah, the HR departments at your MegaCorp XYZ are using 
# automated tools to scan for keywords, and the coop department at your school is trying to beat 
# you into submission to follow some "predefined template".. But, unless what you're aspiring to
# is to be an automaton at MegaCorp XYZ, relegated to writing test harnesses for code that will
#  never see the light of day.. please do yourself a favor, and _be different_! Be bold, dammit. 
#
# (Frankly, I'm falling asleep while reading your resumes.. Wake me up! Srsly.)

I found all of my ubuntu 10.04 rightscale hosts had the same ssh key. The base image they use has one ssh host key that is never regenerated on instance creation, so effectively 100% of hosts are likely to have the same key for each system image.

RightScale has been notified and they are working on notification and fixes for customers.

The script in this gist will regenerate your keys if you have the ones I know of (on the ubuntu 10.04 rightscale image)

REM If you edit this file, make sure to run `unix2dos` to fix those fucking CRLF.

REM Let's keep this script as dumb as possible and do all the logic with a true language.
