we all know the computer Basics you want to turn your computer on you press this
button on the front you want to see what the computer's doing you look at the
monitor you want to reset the computer if it crashes you press this other
button on the front but do you know how to do all of
those things if you're a thousand miles away oh I know I know okay well good for
you smarty pants here's a gold star for everyone else stay

description so there are a huge number of reasons that you might want to be
able to access or control your computer from far away it ranges from totally
mainstream stuff like needing to grab a file off your your desktop for the
homework assignment you were planning to print at school before handing it in
which yeah whatever I think you still understood my point to Enthusiast stuff
like realizing you want to share all those birthday pictures you took of
little Joseph while you're visiting an Josephine and your FTP is down to it
administrator stuff like realizing that someone put Windows on one of your
servers and you need to throttle everyone else in the building's internet
connection so not a moment is wasted while you download your faor Linux drro
mounted as virtual media install it and restore order to the universe so let's
start with more basic Solutions and work our way up to the cooler but regrettably
more expensive ones the first one shouldn't cost a dime because if you
already bought a decent PC in the last 10 years there's a very good chance that
it has a feature called wake on land so
the way wake on land works is as long as
the computer is plugged into wall power even if it's in a shut down state it
actually consumes a little bit of electricity Illuminating power indicator
LEDs on your motherboard or power supply and even enabling functionality like
charging plugged in phones or tablets over special USB ports and you guessed
it keeping your network card Juiced up enough that it can wait for what's
called a magic packet and bring the whole computer to life wake on land can
be configured a handful of ways you can set it up in the ufi or the BIOS of your
motherboard or you can actually do it from within the network card
configuration panel in most modern operating systems you can even specify
if you want a magic packet to only work in sleep versus when the machine is
fully powered down Wake On L has some limitations though it requires either a
separate machine that you can remote into using something like team viewer to
use a utility to send a magic packet or
a VPN or some firewall and routing rules
to be configured for it to work from outside of the local network on top of
that wake on land is not capable of shutting down the computer that needs to
be done through your operating system so wake on land does nothing to help you if
the system hangs and is stuck in an unresponsive state or fails to boot for
one reason or another which leads us then into some janky solutions to this
problem covering a bit of a range in terms of difficulty and expense first up
is a solution I actually really like this is a Bellin weimo you may remember
it from the Channel Super Fun prank where burkel and I made the LMG staff
believe they had triggered the building alarm you're going to want to check that out here this one is relatively cheap
and I already had it lying around but any smart home power socket that can be
remotely switched on and off with an app will work for this so these things are
intended for something like a bedside lamp but by configuring the comp
computer to turn the machine on after AC power loss and every non-lt that I've
encountered has this option buried somewhere within the BIOS you can do a
hard shutdown using the weimo by just cutting power to it and then turn it
back on if for whatever reason it fails to boot and the Machine should try to
boot again well what if I don't want to spend $50 on a clever wall socket good
question the way a PC powers on and off
is simply by bridging two contacts on the motherboard power switch allowing
electricity to flow so it's a short press to power on and to Safe power off
and a long press for about 5 seconds for a hard forced shutdown so get creative
here's a great thread on the Raspberry Pi forums that covers some of the ways
folks have used arduinos and raspberry pies to wire up the power on andof
switches for their remote PCS and actually Luke even told me once about a
solution that he created for someone who didn't want to spend a dime or an any
time but who happened to have a spare laptop with an external 5 and 1/4 in
optical drive where he put the optical drive next to the server's power switch
so he could remote into the laptop and eject the dis tray causing it to bump
the power switch not an ideal solution but definitely creative and the sky is
pretty much the limit here but none of that stuff allows for the computer to be
fully managed in the same way that you could if you were sitting in front of it
and that is where IPM comes in this
super micro motherboard actually a super sexy soon to be relased microatx model
with support for up to 22 core processors four sticks of quad Channel
memory and dual onboard 10 GB network cards the x10
srmf comes with a dedicated additional
Network Port that is just for ipmi or
intelligent platform management interface you assign it a static IP
within the BIOS then you can use any computer on the same network to navigate
to that IP log in and assuming you've got your Java up toate and your security
settings all configured you'll be looking at a whole wealth of freaking
cool tools and functionalities you can see the system
Hardware you can monitor server Health to see if your CPU is running cool
enough and if it's not you can check if your fans are still spinning or you can
set up a different fan curve you can do event logs you can mount virtual discs
and drives you can of course power on or
off the computer in any way you please and you can even do Advanced things like
updating the BIOS or the IPI firmware and adjusting bio settings using the
real-time view of the VGA output that's on the back of the board the problem is
that sick features like a real-time view of exactly what the machine is
outputting often require special Hardware aside from just that Network
Port to be built into the motherboard and while motherboards with add-on ipmi
modules ASUS has a number of them available do exist they mostly come with
ipmi or without it there are kvms that
are remotely manageable but they are much more expensive than investing in
ipmi capable Hardware in the first place and they won't support everything that
an ipmi board can do now to be clear
ipmi is not perfect and poses some
serious security risks I mean remember when someone has physical access to your
machine it's not your machine anymore
but it's the king when it comes to Remote Management and it saved me quite
