Access to the Databar servers and software

The software (mainly Python, ASE and GPAW) that you need for the computer exercises are available in the databar. You are expected to access the databar from your own laptops.  

INSTRUCTIONS

Follow the instructions that we wrote for a PhD school in the summer 2018. 

The instructions are available from the GPAW web pages.

Known issues for Mac users:

- Can not open new windows after 20 minutes.

If you use SSH to log in from a Mac (and from some Linux distributions), a security measure prevents the databar computer from opening new windows if it is more than 20 minutes since you logged in.

To fix it, edit the file /etc/ssh/ssh_config as the super-user on the Mac, and add a magic line to it:

cd /etc/ssh sudo nano ssh_config

This opens a primitive editor. Use the arrow keys to go to the end of the file, and add this line:
