Most of the desktop machine at the STRW can be accessed through the ssh protocol. So when you know your machine name, use that (including the domain) to access that machine directly.

If you do not have a personal machine you can use the virtual machine to log into our systems and continue from there with an ssh to any of the science servers or cluster machines.

Special access

Some places we visit (e.g. China or Iran) or some hotels abroad limit the internet access to web browsing only. Because you want more in such cases the ssh server of the Sterrewacht now also serves the ssh protocol on web ports 80 and 443. So you can now get access to the Sterrewacht computer systems from those limiting environments using

ssh -p 80 -l <your STRW accountname>

With this type of connectivity you can add the tunnelling options (as indicated below) to gain connectivity to a windows remote desktop or your Linux VNC environment.

Instituut Lorentz

For Instituut Lorentz, the server is Desktops and servers cannot be reached directly from outside, so you will always have to go through the ssh server first. But see also our list of details and tricks


For LION, there is

SSH shell access

SSH keys

SFTP and SCP file access

SSH tunnels

For the Mac and Linux commandline ssh client, setting up a tunnel is usually a matter of using the option
-L local_port:remote_machine:remote_port, e.g. -L 3389:windows machine:3389
for forwarding a Windows remote desktop. More detail can be found in the ssh tuning pages.

See putty for instructions about setting up a tunnel with putty (Windows, linux ssh client).

SSH client software

Linux and macOS come with a commandline client for ssh. For Windows, the recommended client is putty
