==== require credentials ====

email the VDC sysadmin to provide credentials and get your remote text terminal prepared.

==== VPN ====

Fileformat 2.0 has been recently released and (re)programming on our side has already started accordingly.
If working from home or elsewhere but from the institute's PC lab (room #6.644) you have to establish a Virtual Private Network (VPN) to Uni first ([https://zid.univie.ac.at/en/vpn/ see ZID/VPN]).
+
 
+
==== SSH ====
+
If working from Windows, you might need to install an SSH-client ([https://www.putty.org/ like PUTTY]) to use Secure Shell (SSH) to connect to your terminal. Accept the server key.

==== usage of a terminal ==== 
+
Now you work remotely and use the remote host's command line (which is the bash shell, don't type the beginning "$", which is the prompt):

the midnight-commander (mc) provides a built-in editor mcedit (exit it with Alt+0)
+
<pre>$ mc </pre>
+
<pre>$ mcedit ts_samp7.rqt </pre>
+
e.g. use  '''''ts_print''''' to process a requirementfile '''''ts_samp7.rqt''''' and get the output '''''ts_samp7.out''''':
+
        <pre>$ ts_print ts_samp7.rqt</pre>
+
<!--

[[File:7_ts_print.png|left|frameless|500px|caption]]

-->
+
   
+
use mc / mcedit to look into ts_samp7.out:
+
<pre>$ mcedit ts_samp7.out </pre>
+
[[File:8_ts_samp6_out.png||frameless|400px|caption]]
+

use e.g. this command to get the switches for the command '''''crsp_print''''':
+
<pre>$ crsp_print /d1  /var/crsp/2019-07/crspdata/cmz201807</pre>
+
 
+
==== download the results onto your desktop / laptop ====
+
use an SFTP client like [https://cyberduck.io/download/ CyberDuck] to download the results (e.g. ts_samp7.out) onto your desktop for further processing. Provide your SSH credentials:
