Re: Eduroam does not work with linux 4.12.13

If, in case, you are from Heidelberg in Germany, this is a working configuration their Eduroam. If you are from somewhere else, maybe it'll help you get in the right direction. It also worked for some other universities so maybe you are lucky.

network={
    priority=1
    ssid="eduroam"
    proto=WPA2
    key_mgmt=WPA-EAP
    eap=TTLS
    phase2="auth=PAP"
    ca_cert="/etc/ssl/certs/Deutsche_Telekom_Root_CA_2.pem"
    altsubject_match="DNS:radius.urz.uni-heidelberg.de;DNS:radius2.urz.uni-heidelberg.de"
    anonymous_identity="anonymous@uni-heidelberg.de"
    identity="*******@uni-heidelberg.de"
    password="****"
}

And let me point out again that by the end of August, before I went abroad, everything worked just peachy with eduroam. I came back three weeks later, and it doesn't work anymore. So the problem should be something upgraded in that gap.

Don't count on it. I had eduroam work one day and fail the next. I needed to redo my configuration. Apparently, support for the configuration I had been using had ended, as when I looked at the documentation, all had changed. Since my university did not actually document the required new configuration, I used a mixture of the most explicit of the illustrated guides (for some kind of smart phone, if I remember right) and information gleaned from scanning the network and picking out relevant details. By the end, my configuration looked almost completely, but not quite completely, different. It was also significantly longer. But it did work.

If there is going to be a switch of authentication, there obviously has to be one day when it works and the next when it doesn't. Would sure be nice if they didn't do the switch silently, though. Perhaps your university is less inclined to behave in this way, but don't count on it unless you really know it. And don't think that because it still works for Windows/Mac users, it isn't a changed-configuration issue. My colleagues did not experience the same problem.

Use https://wiki.archlinux.org/index.php/Wi … ess_points to get information about the network if your university doesn't document it in sufficient detail.

You're sure your university supports ipv6?

Re: Eduroam does not work with linux 4.12.13

I'm also experiencing the problem since ~two days ago. I can't connect to eduroam and neither to another WPA Enterprise network. The last time I used it was two weeks ago (Oct 9th or 10th) and it still worked. I'm using NetworkManger to connect.

Did you make any progress on identifying the problem? My first suspicion was the wpa_supplicant upgrade to 1:2.6-11 from Oct 16th, but I did not time to do any investigation yet.

The way to make progress is to disable NetworkManager and attempt to connect manually so you can see where it fails.

Re: Eduroam does not work with linux 4.12.13

Ok, this seems to be a NetworkManager problem, indeed. I have set up a pure wpa_supplicant config and I can connect to eduroam without any problems.

Re: Eduroam does not work with linux 4.12.13

So, after quite some help from people on IRC (#nm) I was able to nail it down to a DHCP problem (at least in my case). The NM internal dhcp client seems to be the problematic part here. Setting `dhcp=dhcpcd` or `dhcp=dhclient` in /etc/NetworkManager/NetworkManager.conf solves the problem for me.

The question is still if this is caused by the last NM update or if it's just due to a reconfiguration of the network server.

Re: Eduroam does not work with linux 4.12.13

Okay. So today I finally gave up and tried to just remove the eduroam profile from my old university and create a new one based on the account I have at the new university. Of course, this worked without a hitch.

But I am still baffled, because my smartphone still runs with the old uni. configuration, and it works just peachy. So I have no idea what's going on, and I will have to try and test eduroam in other universities over the next couple of weeks and see what's happening.
