Start Mosh with AWS SSM Session Manager
#!/bin/bash
#
# Mush mosh and SSM sessions together.
#
# Run mosh-server on an EC2 instance as part of an AWS Session Manager SSH
# session, and feed the output into mosh-client locally. This is helpful
# if you have an EC2 instance which:
#
# * Is publicly addressable
# * Has a predictable Name tag but a shifting IP
