Flexible script for ssh aliases in Windows

windows_ssh_aliases.ps

#################################################################################
# Summary:
# This basic function is for when you have multiple servers you use login 
# aliases but would not like to manage adding many aliases, especially when
# consistent with minor changes, like hostname.
#
# Setup: 
# This script assumes you are on Windows. Add the below function to your 
# powershell profile. This can be easily edited (or created) with the 
# command:
#    notepad $PROFILE.CurrentUserCurrentHost
# 
# Usage:
# # Simply update the server list in a "host" = "user" syntax, and update domain
# and port variables. This script assumes you use the same ports and domains
# for the servers to access them. It also assumes you have an SSH agent running
# that will server the SSH keys. If you do not, update the $server_connection
# variable to include the path to your ssh key. Should look similar to:
#   "ssh -p $base_port..."
#     to
#   "ssh -i /path/to/rsa.key -p $base_port..."
#
# After which simply type: "lab servername"
