<h2id="tophead">CUCC Expedition Handbook - Your laptop</h2>
<h1>Setting up an Expo laptop</h1>
<h3>Operating Systems</h3>
<ul>
<li>The quickest way to get a complete setup is to use a <b>Debian Linux laptop</b>.
<br>
The <i>expo laptop</i> uses <ahref="https://www.debian.org/intro/about">Debian</a> with the <ahref="https://computingforgeeks.com/how-to-install-cinnamon-desktop-environment-on-debian/">Cinnamon</a> interface, but pretty much any Linux system works fine. This handbook does assume that you are using apt - the Debian package manager - which is good for all Debian-derived Linuxes such as <ahref="https://ubuntu.com/">Ubuntu</a>. Old, slow machines without much memory can be very effective with <ahref="https://xubuntu.org/">Xubuntu/xfce</a>.
<li>Windows machines can do almost everything needed (rsync is a problem), but some useful software has no Windows version and you will need to find your own equivalents. There are also dangerous 'gotchas' to look out for because the file-naming system is different. Do use Linux if you can.
<li><ahref="winlaptop.html">A Windows laptop for expo</a> - a page of more detailed instructions for those who are definitely going to be using a Windows PC or laptop.
<li>WSL: the Windows Subsystem for Linux. The first release of this didn't do the ssh key exchange process easily. The <ahref="https://docs.microsoft.com/en-us/windows/wsl/install-win10">2019 WSL2 release</a> includes a complete Linux kernel. If you want to use this, then please do - and then write the handbook documentation too. But beware that it has <ahref="https://docs.microsoft.com/en-us/windows/wsl/wsl2-index">two different modes</a> which behave differently.
<li><ahref="https://github.com/CaveSurveying/tunnelx">Tunnel</a>: 2.5D cave drawing program based on Survex-compatible data which can also read PocketTopo files. (Generally called 'tunnel' even though the project and executable is actually 'tunnelx'.)
<li><ahref="https://sourceforge.net/projects/viking/">Viking</a> - an alternative to GPSprune. The <ahref="https://github.com/viking-gps/viking">code</a> is on github.
<li>python, if you are extending troggle or the scripts in expoweb/noinfo/ - already installed on Linux <imgsrc="https://www.python.org/favicon.ico"width=64hspace="20"align="right">
<p>Nearly all our Austrian surveys have beeen produced using Tunnel but we are moving to Therion for new caves because Therion does elevations properly and Tunnel never will.</p>
<li><ahref="https://git-scm.com/download/gui/linux">GUI for git</a> - There is a choice on Linux but many people just use the command line.
<li>Your favourite syntax-highlighting code editor. <ahref="">gedit</a> is installed on the <em>expo laptop</em> has syntax highlighting for .svx files too. This works with <ahref="https://survex.com/changes.html">all GtkSourceView-based editors</a> (thanks to Phil Withnall).
<li><ahref="https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html">PuTTY</a> including pagent. Version 0.73 was released on 2019-09-29. You need this to generate and to use ssh keys on Windows. Otherwise none of git, mercurial, scp, ftp or rsync will work. It includes command line tools ssh, scp (pscp) and sFTP (psftp).
<li><ahref="https://gitforwindows.org/">Git for Windows</a>
<li><ahref="https://tortoisegit.org/support/faq/#prerequisites">TortoiseGit</a> - GUI interface to git
<li><ahref="https://notepad-plus-plus.org/">Notepad++</a> or any other syntax-highlighting code editor for HTML and python such as <ahref="https://www.aptana.com/">Aptana Studio</a>. Configuring these to syntax-highlight .svx files has yet to be done.
<li><ahref="https://www.cygwin.com/">Cygwin rsync</a> - not installed as standard on Windows so you need to get Cygwin or <ahref="https://serverfault.com/questions/878887/rsync-server-using-windows-subsystem-for-linux">use WSL</a>. But getting WSL to work with ssh keys has been <ahref="https://heejune.me/2018/08/02/setup-rsync-server-over-ssh-on-windows-server-2012-easy-way/">tricky</a> and pagent-managed ssh keys are apparently not visible to ssh and rsync in WSL. If you find a good solution for Windows please edit this documentation.

<li><ahref="https://osmand.net/">OsmAnd</a> - a GPS app. See also <ahref="../essentials.html">the expo GPS configuration pages</a>
<li><ahref="https://sites.google.com/site/speleoapps/home">TopoDroid</a> makes cave surveys with the DistoX.
<li><ahref="https://sites.google.com/site/speleoapps/home">Cave3D</a> is a Therion 3D viewer.
<li><ahref="https://sites.google.com/site/speleoapps/home">ThManager</a> organizes single surveys, exported by TopoDroid, into Therion projects encoded by Therion "thconfig" files.
</ul>
<h3>Logins to external systems</h3>
<ul>
<li><ahref="https://github.com/join">Github</a> - create your own github account if you don't have one already.
<li><ahref="https://bitbucket.org/product/">Bitbucket</a> - create an account to help develop tunnel. <imgsrc="https://tortoisehg.bitbucket.io/img/bitbucket-icon.png"width=64hspace="20"align="right">
<ahref="keyexchange.html">key exchange</a> procedure - which you can only do entirely on your own if
you have access to the <i>expo laptop</i> to upload and install the public key generated by your laptop. Do this first, Without it none of git, mercurial, scp, ftp or rsync will work.
<p>On a Windows machine you will need to configure pageant (the putty authentication agent)
to <ahref="https://blog.shvetsov.com/2010/03/making-pageant-automatically-load-keys.html">run at startup to load your key</a>. Note that you are loading your <em>private</em> key, the .ppk file, into pageant and that this key never leaves your laptop.
<p>The above gets TortoiseHg and the command-line PuTTY tools (ssd, sftp, pscp) running, but doesn't get Cygwin rsync working. You might like to try <ahref="https://stackoverflow.com/questions/23517023/rsync-from-windows-to-linux-using-puttys-pagent-authentication">this</a> (untested).
<p>When using Windows please, please be <ahref="http://expo.survex.com/handbook/survey/getin.htm#filenames">excessively careful when naming files and survex names</a> and be <ahref="../manual.html#quickstart">exceptionally careful when using rsync</a>.
<p>The handbook has documents where it is necessary to use scp or sftp to manage large files in 'expofiles'. See <ahref="../upload-expert.html">Experts: Uploading files</a>, <ahref="../uploading.html">Uploading files</a> and <ahref="../gpxupload.html">Uploading GPS tracks</a>. Only machines which have done the key exchange process can do scp, sftp or rsync.

<p>When maintaining the HTML files in the expo handbook a link-checker is useful to report bad URLs (links to external sites go bad regularly) and to find orphaned pages with no in-links. The website has <ahref="https://www.klebos.net/subdomains/keldos/LinkScans/TUNNEL-wiki-link-report.html">about 2,000 internal URLs</a> in just the Tunnel wiki section alone.
