Preparation
Download & Installation
Authentication
Xpra must communicate with JURECA via Secure Shell (SSH)
and JURECA requires authentication to be password-less using SSH key-pair.
Please test your system before you proceed.
Execute the command with your JURECA-userid on your local workstation.
It must return the word 'success' for a successful SSH connection to JURECAVIS.
Linux/MacOSX:
ssh <YOUR-USERID>@jurecavis.fz-juelich.de echo "success"
Windows/Putty:
"C:\Program Files (x86)\PuTTY\plink.exe" -ssh <YOUR-USERID>@jurecavis.fz-juelich.de echo "success"
Ensure you have loaded your key in PuTTY´s SSH key agent called Pagent before!
Using Xpra requires three general steps.
- Start Application as Xpra-session on a JURECAVIS node.
- Start Xpra-client locally on your workstation.
- Connect with Xpra-client to Xpra-session on JURECACVIS node.
1. Start Application
ssh <USERID>@jurecavis01.fz-juelich.de module load Stages/Devel module load GCCcore/.5.4.0 module load Xpra xpra start :100 --start-child=xterm
2. Start Xpra locally
3. Connect

Background Information
Authentication:
Xpra must communicate with JURECA via Secure Shell (SSH).
It is mandatory that JURECA trusts Xpra and is 100% sure
that the incoming connection is by a certain user and no none else.
Hence, each new SSH connections starts with an authentification procedure.
SSH supports different authentification methods, but not all are available on any site.
Xpra must be used with the most secure Public-Key Authentification (PKA) to connect to JURECA.
PKA is based on a SSH key-pair with a private key and a public key.
The private key never leaves the local machine and the public key must be installed on the remote machine.
Anyone who knows the private key can now connect to the remote machine.
