The mailing list for users of the eduroam Configuration Assistant Tool (CAT)

[Robert Grätz <graetzrx AT cms.hu-berlin.de>]

Hello Dennis,

I checked your manual for eduroam for linux [1]. Is it possible that 
this is deprecated? Your description is for a shell script, but at CAT 
you get a python file for your institution.

You should call your script with:

python3 eduroam-linux-Universitat_Bremen-eduroam_ AT uni-bremen.de.py

If you need root rights with this call please tell me the  linux distro 
and the version. Then I could hopefully reply it.

Best regards

Robert
