(though we will, as we will want to do operating system updates during the year and maybe fix that keyboard) as all the caving data updates are continuously
synchronised with the public server expo.survex.com during the expo.</p>
<p>For experienced expo surveyers the <em>Expo laptop</em> is also set up as an
<ahref="bulkupdatelaptop.html"><em>Expo bulk update laptop</em></a> with file-transfer and version control capability to the expo server. New expoers should use the web forms, which work from any browser on any laptop.
<p>You can
configure your own laptop to do <ahref="bulkupdatelaptop.html">bulk upload</a> of many files and
manage the version control yourself, but
initially it is easier to use the <em>Expo laptop</em> as the software is already set up (cryptographic key
<p>The <i>expo laptop</i> is called "Crowley". Crowley was rather too ill to be useful during the 2022 expo (being left in the potato hut for 3 years was not a healthy experience) but is now feeling much better... apart from the WiFi which died in typical fashion just 10 minutes before a training session (a software driver update issue, but Crowley is connected to the ethernet cable so this is not vital).
<p>In 2023 we will have another general-use laptop (it was also on expo in 2019). This is not connected by any cabling and just uses WiFi. Like the <i>expo laptop</i> it is running Debian and has the same set of software installed
(survex/aven, tunnelx, therion, git etc.) and you login to it using the username "expo" and the usual cavey:beery password. It has the identical[Cinnamon/Debian] configuration and survey software installed as Crowley. It is a big, heavy R61 14-inch Thinkpad on loan from Michael Sargent and it is called "Aziraphale". Azirophale has a big enough solid-state drive (128GB, new for 2023) to hold <var>/expofiles/</var> (but note that Azirophale's SD code slot doesn't work).
<p>Both laptops have had RAM upgrades and solid-state disc upgrades over winter 2022/23. They each hold a local complete copy of <em>expofiles</em> and the <em>expoweb, loser, drawings and troggle</em><ahref="repos.html">repositories</a> but do not have the troggle software configured to run locally, though this could be enabled if necessary.
is a dual antenna WiFi tiny black box on a small shelf high above the sink/stove area and connected via a usb cable to the tiny dark-blue Acer netbook 'tclaspire3'. In 2023 there may be no separate router: routing may all be done by this Acer notebook [PENDING UPDATE - correct as of 20 March 2023].</p>
<p>The Gasthof WiFi - which you can still use - is "StaudnGast" and has no WiFi password but there is a login webpage. It allocates IP addresses in the range
<p>The Acer Aspire One ("tclaspire3") is on a static address <ahref="http://192.168.1.100/">192.168.1.100</a> on WiFi but <ahref="http://192.168.200.100/">192.168.200.100</a> on the ethernet cable.
This used to need running once or twice a day when the internet stops working, but it was radically fettled in 2022 and so should be much more reliable.
Sometimes you may have to walk over to the blue Acer Aspire netbook and run this script directly by typing on its keyboard
<p>In 2018 and 2019 we had good Internet access at basecamp, but the router was returned to its owner during Covid and in 2022 Wifi reception from the gasthaus was poor. A new Wifi device (not a router, just a dual-antennae receiver) is to be used in 2023, pending configuration with the acer aspire netbook, which we hope will improve everything to how it was in 2019.
