\section{Hardware Overview}

\begin{itemize}
    \item OPNsense is based on FreeBSD \\ \url{https://opnsense.org/}
        \\ \url{https://wiki.opnsense.org/index.html}
    \item Iris FW1100 datasheet \\ \url{https://www.supermicro.com/products/system/1U/1018/SYS-1018D-FRN8T.cfm}
\end{itemize}

The Supermicro SuperServer 1018D-FRN8T is a 1U server with front I/O.
That means that both the rear I/O ports as well as the I/O expansion
ports are found along the front side of the rack. In many cases this
is a desirable configuration as it can make cabling very simple.

\begin{figure}[!htb]
    \includegraphics[keepaspectratio=true,height=1.10\textheight,width=1.00\textwidth,angle=0]
        {sf-fw/ss-front.png}
    \caption{Supermicro SuperServer 1018D-FRN8T Front}
    \label{fig:supermicroSSfront} 
\end{figure}

The rear of the unit has a redundant 400W power supply. Rated at 80
Plus Platinum the power supplies are efficient as well. The remainder
of the rear is simply a bezel for fans.

\begin{figure}[!htb]
    \includegraphics[keepaspectratio=true,height=1.10\textheight,width=1.00\textwidth,angle=0]
        {sf-fw/ss-rear.png}
    \caption{Supermicro SuperServer 1018D-FRN8T Rear}
    \label{fig:supermicroSSrear}
\end{figure}

The onboard I/O is plentiful. There are two USB 3.0 ports along with
a VGA port for \gls{kvm} carts. Above the USB ports there is a RJ-45
Ethernet port for out-of-band management that can be directly
connected to a dedicated management network. 
%-------------------
Furthermore there are
six 1GbE ports connected to two Intel i210-at controllers and an
Intel i350-am4 controller. The two SFP+ ports are controlled by the
Xeon D’s Intel X552 NIC. For \glspl{firewall} and other appliances, this is
a very strong configuration.

    \caption{Supermicro SuperServer 1018D-FRN8T interfaces}
    \label{fig:supermicroSSinterfaces}
\end{figure}

Inside the system we see a redundant set of fans near the PSU bezel
and a very small motherboard inside. One can see our two stacks of
Seagate Enterprise Capacity V3 1TB 7200rpm drives as well. We removed
the PCIe riser and the airflow shroud from this picture to show off
the internals better.

\subsection{Remote Management}

%(11:43:34 PM) forksand@jabb.im: I'm doing the install a bit different.
%After doing the opnsense installer and booting up, i *only* set up the
%firewall WAN interface statically. This allows you to admin from the WAN
%interface. If you configure a LAN, it firewalls out the WAN from remote.
%So to get started, I have to just to the WAN, then write a rule that
%allows WAN remote access.
Supermicro’s \gls{ipmi} and \gls{kvm}-over-IP enables deployment flexibility.
One can do remote power up, power down, and reset of the server in
the event that it becomes unresponsive.

\begin{itemize}
    \item fan speeds, chassis intrusion sensors, thermal sensors,
        and etc. can be monitored remotely
    \item remote power control. One can do remote power up, power
        down, and reset of the server in the event that it becomes
        unresponsive.
    \item alerts can be setup to notify the admins of issues.
    \item remotely mount CD images and floppy images to the machine
        over the dedicated management Ethernet controller. This keeps
        maintenance traffic off of the primary Intel NICs.
        At the same time it removes the need for an optical disk to
        be connected to the Supermicro motherboard.
\end{itemize}

Supermicro's BIOS has a feature: the BMC IP address shows
up on the post screen!
If you have a \gls{kvm} cart hooked up to the system, it gives an
indicator of which machine one is connected to during post.

Supermicro does include \gls{kvm}-over-IP functionality with the motherboard.

\begin{itemize}
 \item Default \gls{ipmi} connection is in cleartext http.
 \item SSL certificate for Supermicro \gls{ipmi} is bad (like all of them).
 \item Can't change password on \gls{ipmi}.
 %\item Root password for server and \gls{ipmi} is sent via email.
 %\item There is an attack window between their machine imaging and first login.
 %\item Customer should control timing of first power on.
 %\item System is also possibly vuln during the ISP's initial power up and commissioning period.
 %\item First reboot, the system hung (.png XXX).
 %\item Hard reset, lots of DHCP queries at boot.
 %\item A \texttt{debian} user was on the system, password unknown. Check \texttt{/home}!
 %\item They block NTP to prevent \gls{ddos}, so you have to use their time server
 % \texttt{time.sharktech.net}
\end{itemize}
