 The ~/.ssh/connections/ directory needs to be created if it does not already exist.  With this configuration in place, you can log in to the computing front end with {{{ssh -t DMZ_HOST ssh SEC_HOST}}}.  The DMZ_HOST does not support commands other than ssh and scp, and is used only to bounce the connection to SEC_HOST.

+As the DMZ_HOST does not have available disk space, data transfers need to write directly to the SEC_HOST disks.  The following commands illustrate how to use scp to transfer files to and from SEC_HOST:
+
+{{{
+scp @LOCAL_FILE@ DMZ_HOST:SEC_HOST:/@PATH_TO_DESTINATION@/
+scp DMZ_HOST:SEC_HOST:/@PATH_TO_FILE@/@REMOTE_FILE@ @LOCAL_DESTINATION@
+}}}
