Networkmanager suddenly stopped connecting to eduroam

I'm running MLED 64bit on my laptop and used to be able to connect to the universities wireless system, ie eduroam. However without changes to the config itself suddenly this has stopped working and I'm at a complete loss how to fix this as there is nothing obviously different and no hints visible in the logs.

Hopefully someone can point me in the correct direction as I've reached the point that I see no other solution then a complete reinstall.

Observations:
1) After I last connected successfully to eduroam I installed the following list of packages, from which nothing stands out to me as potential culprit.

Code:

2) Connecting to wireless at home on the same laptop works without issues.

3) Booting into a SystemrescueCD from USB on that same laptop allows me to connect to eduroam, proofing it is a problem at my end.

4) The only clear difference in the logs is in the wpa_supplicant logs:

- successful

Code:

wlan0: CTRL-EVENT-REGDOM-CHANGE init=COUNTRY_IE type=COUNTRY alpha2=GB

wlan0: CTRL-EVENT-EAP-STARTED EAP authentication started

wlan0: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=25 -> NAK

wlan0: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=21

wlan0: CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selected

wlan0: CTRL-EVENT-EAP-PEER-CERT ...snip...

wlan0: CTRL-EVENT-EAP-PEER-CERT ...snip...

EAP-TTLS: Phase 2 MSCHAPV2 authentication succeeded

- unsuccessful

Code:

wlan0: CTRL-EVENT-EAP-STARTED EAP authentication started

wlan0: CTRL-EVENT-REGDOM-CHANGE init=COUNTRY_IE type=COUNTRY alpha2=GB

wlan0: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=25 -> NAK

wlan0: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=21

wlan0: CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selected

wlan0: CTRL-EVENT-EAP-PEER-CERT ...snip...

wlan0: CTRL-EVENT-EAP-PEER-CERT ...snip...

wlan0: CTRL-EVENT-EAP-FAILURE EAP authentication failed

The removed hash details from the above log-snippets are identical. The noticeable difference is that in the failed attempt no mention is made of connecting using MSCHAPV2 authentication which it is supposed to do.

Does this trigger any thoughts?

As the connection appears to failing during the TTLS negotiation, then I would be looking at the openssl packages that were installed.
I suggest removing them and reinstalling the 64-bit versions.

This is a multilib system, so the 64-bit versions of both openssl and openssl-solibs are still present. These 64-bit versions got installed before the mentioned round of updates that included the compat32 bit ones. I'll try to reinstall the openssl packages, but won't know whether that makes a difference until back at a site with eduroam (and dragging two laptops with me isn't fun).

I had a similar issue, based on an upgrade of wpa_supplicant. It is discussed in the following thread.
http://www.linuxquestions.org/questi...se-4175544588/

The solution was to downgrade wpa_supplicant via a package mattallmill provided (see the thread).

Actually, I still don't know why this happened...

Good luck

Thanks for that link fsauer. That appears worth a try in case reinstalling openssl doesn't fix the problem.

btw) In my case I installed the upgrade for wpa_supplicant earlier and eduroam was working with the 2.4 version until recently.

edit) The link to the 2.3 in that topic is no longer working, but I'm sure it is possible to find it online.

In case you want to try: https://dl.dropboxusercontent.com/u/...3-x86_64-1.txz

Thanks for that link. Unfortunately in my case replacing wpa_supplicant with the 2.3 version doesn't fix it. So it looks like time to give up and reinstall the system as reinstalling openssl also made no difference. :-(
