<h1>Expo server in Potato Hut</h1>
The expo server runs the tatty hut music system and is a core node of the survey data version control system.
<p>
The <em>Expo server</em> is (2017) an Acer Aspire netbook. Plugged into it with cables are
<ol>
<li>Printer
<li>Hard drive
<li>Speakers (for music)
<li>Router (for networking)
<li>The Expo laptop 'tunnock'
</ol>
<p>The <em>Expo laptop</em> 'tunnock' is another laptop which is connected to the server by a cable and not by WiFi. It runs Linux and has installed all the software for talking to the server for:
<h1>Expo computing setup</h1>
<p>In 2018 there is no in-hut expo server and fake internet - we are
(trying) using the real net, so the set-up on expo is exactly the same
as the rest of the year. An expo laptop is provided, but you should be
able to use your own computer in exactly the same way if you brought one.</p>
<p>The networking hardware is an Acer aspire netbook to manage the
connection to the Gasthof and firewalling, plus a WNDR4000 router/AP
to provide local connectivity.</p>
<p>The <em>Expo laptop</em> 'debian' is a Dell laptop (loaned by Phil
Sargent) which is connected to the router by a cable and not by WiFi
(it's wifi doesn't work - although that can probably be fixed). It
also has an external keyboard as a coupleof vital keys are dead
(e.g. down-arrow). It runs Linux and has installed all the software
for talking to the server for:

<li>Typing in survey data
<li>Uploading survey data

<p>Any laptop or phone can connect to the server via the "tattyhut" WiFi and, with some configuration, can be set up to do all those things too (but nothing else - it is not connected to the internet). New expoers are advised to use the Expo laptop first to see how it all works.
<P>
Either the Expo laptop or your own laptop will use the version control system to synchronise cave data. Many people prefer to use the expo laptop 'tunnock' as then they don't have to install any software on their own machine.
<P>[Through the miracle of the distributed version control system, people who take their laptops home (or across the road) to connect to the internet can update the public server expo.survex.com with all the latest cave surveys. Rely on other people to do this is this is your first expo.]
<p>
At the end of expo the server is brought back to the UK and any remaining updates are synchronised with the public server expo.survex.com .
<h3>2018</h3>
<p>
For some years the Expo server has served it's own DNS domain name "potato.hut" and published WiFi as SSID "tattyhut" as it's own private network - which was NOT connected to the Internet.

<p>Either the Expo laptop or your own laptop will use the version control system to synchronise cave data. It's easier to use the expo laptop as the software is already set up. But if you set up your own computer then you will get a more familiar environment. See the <a href="update.htm">Expo Website Manual</a>for info on how to do that.</p>
<P>Through the miracle of the distributed version control system, everyone can edit the data and it should all get merged.</p>

<h3>2018</h3>
<p>Prior to 2018 we have run a mini-internet with our own DNS domain name "potato.hut" and published WiFi as SSID "tattyhut" as its own private network.</p>
<p>In 2017 the hard-drive died and as part of a general reconfiguration we are intending in 2018 to connect the server to the internet via the Staudnwirt router (which provides the WiFi over the road). This may not work, in which case we may have to revert to the private-network scheme...</p>
