Dear CAT eduroam community

 

I hope I’ve chosen the correct email list, otherwise, please just let me know.

 

I am part of the network & security team, responsible for the WiFi infrastructure at the University of Bern; the AAA backend is operated by another team. Nonetheless, I also help supporting the client side from time to time. Right now we have a ticket with a phD  student, trying to setup eduroam on a CLI-only Linux distro. My Linux knowledge is above average, but far from expert level.

 

Some questions concerning the issue:

 

1. In general, is it possible to use the python CAT installer on linux in a CLI-only environment? I would know how to configure it manually with wpa_supplicant.conf, but we try to encourage our employees and students to use the CAT installer / profile instead…

 

2. I tried it on a my test client with Ubuntu 22.04.3 LTS and get the following error (sorry, the input prompts are in German, but at least the exception is in English):

I know there would be ways to change the permissions for the nmcli, but I don’t want our student to take any risks at this.

 

3. On GitHub I found the following change note:

 

Changes in 2.1

…

[FEATURE #7] introduce a Linux "bash" installer in parallel to the Python one. Disabled by default.

 

à Where can this be “enabled” and would that solve the CLI-only installation problem described above?

 

Any help would be appreciated a lot!

 

Thanks in advance, best regards and have a nice weekend

Dominic
