file sharing, cloud, encryption

Filesharing and cloudstorage: is quite difficult with windows (It does simply not always work) but it is usefull for transfering measurement files without the help of athena (for larger stuff) For a purely local network a router is needed but and then Lanshark   or p300 does really help

who likes it more sophisticated can set up his own ftp server: software for this excits plenty:  I used:   the server from  or the server from  

I heard about the mini sftp from h

 to make your own network assisted storage (a networkdrive) with FreeNAS or company cloudservices(but be carefull about the Data-safety here!)

You can set your own cloud server relatively easy with owncloud  or use

company clouds (just a few it is difficult to keep track)

Data encryption for clouds
Veracrypt creates big container files that can be used as external drives, however even small changes need to sync the whole container that why this is a good choice for local storage but not for clouds

A better way however is to encrypt all the files separately with a tool like cryptomator

Remote Control

nearly all operating systems offer a inbuild version but as soon as you need to cross borders you want to choose something different: Be aware by using non opensource tools for remote control you grant the company access to the pc you are controlling, so its all a question of trust!

VNC for remote controlling is the tool of the trade!

One trick here is to use dyndns ( if the PC changes ip adress but all our PC's don't!

For private use teamviewer is nice. Th definition from teamviewer is “whatever you do not get payed for”. So some short remote help this might be a nice choice
For windows there is another tools without installation

Instant screen sharing offers some fast way to look on the screen (no control)

For teachers there is a nice little tool that allows the control of the other pc's in the system and allows screen sharing.

Remote Linux work

One of the classical tools is Putty

I stumbled recently over one alternative that seems better in many ways


I create small webpages with partners to communicate information. This works like a mini wiki and is free with a google account.
important is here to back up yours sites from time to time (you never know when google asks money for it) for this is extremly helpful

for sorting your mind a small wiki on your pc is helpful
for more projects you should choose the right platform here

Small usefull tools:

Little tool to make online surveys for free (maybe for course feedbacks and similar things)

Tool that downloads the whole webpage (including all subpages) for local storage

Little tool to share a white board online, no installation works in browser, just share the address for a specific board or

Little tool to make scheduling for meetings easy:

Little webpage that removes banners and other things from other webpages for better printing


For the mobile phone one of the most versatile tools for creating or reading qr codes is QRdroid the PC there are two general ways.

Simple QR codes can easily be generated using freely available online tools like:

QR Monkey or QR code generator

For more options

I you already use Inkscape (see 2 plotting and poster) the function is build in Extensions > Render > Barcode > QR Code

a small freeware tool like the portable QR code generator (in german!) is very useful.

Interesting is also this tool (free for personal use only) since it can bind in logos in the code

There is a whole community creating so called Halftone QR codes that combine pictures with QR codes and that I find very interesting, see for example this project page for more info

VPN to Lund     

For members of the Lund University network this can be accessed from the outside with vpn
but easier is to download the fortinet client from here
and login with servername:” “ and your Lucat id/password

Eduroam for European Universities:
Interesting feature might be the “eduroam access” That means every educational institution in Europe gives you free W-lan access with the connection over Lund. So you slip to run in every university to the network administrator to get a free access. In many this is just a wifi that you can sign up to. I found this extremely usefull all over europe.

For some  you need to download and install:  (works only from university network! So use the vpn from before)  LDC gives instructions for the installation here:
