Subject: Re: Question about geteduroam on an 'on boarding' VLAN

 

Hi,

This is because one more hostname was missing from a temporary proxy to fix profiles, but we removed it (since that's no longer necessary with CAT 2.0.4).

Can you (have them) try again?

Regards,
Paul

Hi Paul et al,

 

Our member at Cardiff has added the discovery.eduroam.app CNAME to his allow list and gets a bit further. The screenshot attached happens next. They only have one profile, so it can’t be a question of multiple profiles.

 

It looks to me like an unhandled exception in the app. So... any thoughts/suggestions on possibly getting you a debug log?

 

With Kind Regards

Hi,

Currently cloudfront (the CNAME lookup will tell you that) but I'd rather keep the ability to change this over time.

If their DNS whitelisting would require whitelisting of what the CNAME points to, I'd create "alias" records instead on a different record.

If they do lookups for IP-addresses and whitelist those in the firewall instead of DNS, I'm not sure that would be sustainable.

Regards,
Paul

Hi Paul,

 

Knowing which CDN you’re using for discovery.eduroam.app could certainly be useful, but yeah... I don’t know if CNAME entries will work or not.

 

I since also noticed the thread between yourselves, Cambridge, York and Strathclyde. You can add Cardiff to the list of those universities that use an on-boarding network.

 

With Kind Regards

Hi,

Ah, this question came up recently on cat-users too:

Hi,

 

One of our members is attempting to use geteduroam, but they find that the setup fails half-way through. The network they are using is a DNS-restricted VLAN, i.e. it is there purely to on-board their students and staff and as such limits access to only Google Play and eduroam CAT (and probably geteduroam).

 

They’ve attempted to add as many locations as possible they can think of, but it fails.

 

Is there any way to get debug logging for geteduroam (which we’ll be happy to get the member to provide), and do you know whether geteduroam uses a CDN per chance, and if so, which subnets of it should be allowed?

 

If you could let us know, that’d be fab! ☺

Of course!

The geteduroam Apps use the 'discovery.eduroam.app' hostname for the CDN/discovery files.

This is a CNAME actually; does that work with the whitelisting in DNS?

Besides this, 'cat.eduroam.org' is required for the CAT profiles.

Ah, I now realize I forgot another host that is still in the path. We should think about making that a prettier one than it currently is (a serverless endpoint, that I wouldn't want people to whitelist), but I'd need to know whether CNAMES work or not. And, well, we fixed some things on the CAT profiles that are no longer required actually since the last CAT 2.0.4 update.

I really didn't think about this way of onboarding/whitelisting, but I understand it's purpose. I thought I remember Stefan (W) wrote at some point that it wasn't the best thing to do with CAT either, but I fully understand why people do this, and don't want to make it impossible either.

Regards,
Paul
