DHNET 802.1x PEAP Authentication for wired network
location: linuxquestions.com - date: October 6, 2007
I am a student at the University of Florida that uses Linux. Recently, the Department of Housing decided to switch over to 802.1x authentication. As a result, I am currently unable to get my Linux machine working with their system. I installed the WPA_Supplicant and WPA_GUI and used the wpa_supplicant.conf file provided by the university. Whenever I try to authenticate, it say EAP Authentication failed.
I am using Fedora 7. I am trying to configure this to work with a wired connection. My network device is eth0 and I am using the wired driver. The WPA_Supplicant appears to be working in conjunction with the network manager, but cannot authenticate. An IP address is assigned however. There is just no internet access.
While they have detailed tutorials for XP, Vista, and MAC, the linux section includes only a supplicant file and no directions. Below is the contents of that file. Please not that the IPS certificate mentioned in the windows configuration is not included in this file.
Joining a Windows domain and authenticating using 802.1x on a wired network
location: ubuntuforums.com - date: November 4, 2008
For a while, I tried to figure out a way to get my Ubuntu machine to work on our corporate network, which is a MS Windows environment and uses 802.1x machine based certificate authentication for network access.
I was unable to find any how-to's to do something like this, but I did manage to find enough information here and there to to figure out how to make it work. The main issue is that most organizations don't use machine based certificate authentication, but rather user authentication; but for those that were in my situation, I hope this guide helps.
Feel free to give me any feedback of any issues you come across while getting this to work.
This document is written from the point of view of our corporate network, like our in-house Certificate Authority and so forth, so you may need to substitute something like Verisign for yours.
Also, apparently some of the formatting was lost in my copy and paste from my word document to this forum, so hopefully it wi
Cannot connect or authenticate to 802.1x (PEAP) WiFi Network
location: ubuntuforums.com - date: August 16, 2013
I recently received a username and password to use on our corporate WiFi however I am unable to connect to it from my laptop running Ubuntu Raring 64-bit. I can connect to it using my Android phone since it has an option to specify the inner authentication as none however on Ubuntu it keeps prompting me for my password.
What I have tried thus far is a fair amount of searching which eventually led me to this unresolved thread where a few users are having the same problem. I also found another thread that suggested I remove the system-ca-certs=true line from the config file in /etc/NetworkManager/system-connections/ but alas that did not help either.
In the aforementioned unresolved thread it says something about manually editing the wpa-supplicant.conf file to get it to connect but I'm not exactly too sure how to go about doing this. If anyone could provide me with some guidance I would be greatly appreciative!
HOWTO Join ubuntu to AD domain, and perform wired 802.1x MACHINE AUTHENTICATION.
location: ubuntuforums.com - date: May 3, 2013
Many corporation deploy 802.1x machine authentication, because it's more secure than username authentication. Here's a guide of how to do such authentication.
The basic idea is that when a machine joins an AD domain, DC generates a password corresponding to that machine name. The password is transparent to administrators, but an open source software "likewise open" can get this password. So we can use machine name and password to do a 802.1x machine authentication, with PEAP-MSCHAPV2, other than EAP-TLS certificate.
1. Suppose that you'd setup a valid 802.1x machine authentication environment, including switch, AD domain and NPS server.
2. Join ubuntu to AD domain (quite simple):
apt-get install likewise-open
domainjoin-cli join <domain dns name> <domain account that has join-domain right>
, and password will be prompted.
3. Get machine password, and do 802.1x machine authentication:
802.1x PEAP protected authentication problems
location: linuxquestions.com - date: September 20, 2008
Ok so, I'm at the University of Florida and they use an 802.1x authentication for their wired (and I'm assuming wireless) internet connection. I can't get this to work on anything save Ubunutu.
On Ubuntu, the university provides instructions on editing files and such, but some of the files are ubuntu-specific files that aren't on other distro's (for example, they tell me to edit /etc/NetworkManager/dispatcher.d/01ifupdown). I have a slew of other problems with ubuntu and would really prefer not to use it.
I tried installing xsupplicant but i keep having issues installing it, and I'm pretty sure you can do it with wpa supplicant but i have no idea.
I really want to be able to connect to the internet using slackware or openSUSE or Fedora, or really anything other than Ubuntu.
Sorry if i didn't provide enough information, this is my first post =/
HOWTO: ipw3945 connecting to a University Network (802.1x / PEAP)
location: ubuntuforums.com - date: September 3, 2006
First of all this is my first HOWTO and it details how I got connected to Lehigh University's wireless network with wpa_supplicant. I decided to post this as I was having trouble finding info on this subject [of connecting to a University 802.1x network] and figured this might serve as a springboard to help others connect to their own 802.1x University networks.
**I recommend backing up all config files before editing them and take no responsibility for any damage this may cause**
Ok, that said let's get started, first make sure you have the wpa_supplicant installed.
sudo apt-get install wpasupplicant
Now create the wpa_supplicant configuration file
sudo gedit /etc/wpa_supplicant/wpa_supplicant.conf
then paste the following, edit as needed and save.

Configuring Wired Network Authentication 802.1x
location: ubuntuforums.com - date: February 5, 2011
I just installed Ubuntu on my laptop and I'm having a bit of difficulty connecting to the internet. I'm at the University of Pittsburgh, and like many other colleges, we have to authenticate in order to use the wired ethernet connections in our rooms.
I've tried to use the network manager to connect by enabling 802.11x authentication, and changing the settings to the following:
Anonymous Identity: tried both blank and my user nameInner Authentication: MSCHAPv2
CA Certificate: I used the certificate that my school supplies
After entering these settings and some other variations, I always just see the network icon look like it's connecting or searching but I never am connected to the network. Sometimes I'm thrown back to the configuration panel where I entered by username and password, but I never get an error or any kind.
My searches on this forum lead me to many mentions of wpa_supplicant for authentication, but I'm not sure if that's necessary anymore
Intermittent network connection using 802.1x wired
location: ubuntuforums.com - date: October 4, 2010
I'm trying to connect to a university network using tunnelled TLS with PAP. I can connect okay, but my connection drops seemingly randomly at varying intervals of usage, i.e. sometimes after 10 minutes, other times after 4 hours. I haven't found that running any particular application causes the problem.
I've been checking /var/log/daemon.log, and found an interesting snippet, which I believe is connected to my problems, (everytime my connection drops, there is the following message just written to the log)

wired 802.1x authentication failures
location: ubuntuforums.com - date: May 29, 2015
I have a desktop running 14.04 that is connected via ethernet to an enterprise 802.1x network. The connection was functional until today, when I had to change my domain password. I updated the password in wpa_supplicant.conf and rebooted. After restart, I was prompted for the 802.1x password, but the connection does not successfully authenticate and I get an endless loop of pop-up authentication requests. The password is entered correctly and I can connect to the same network on both Windows and Mac OS devices.
This error is reminiscent of the problem I had encountered when initially setting up this device, and that other users have encountered, that was solved by deleting the line system-ca-certs=true from the config file in /etc/NetworkManager/system-connections. However, that can't be the problem now.
Here is the (redacted) contents of wpa_supplicant.conf:

can you somebody tell me how should look wpa_supplicant.conf file for 802.1x authentication in Ubuntu OS?
Here is Windows config which is functional:
- enable IEEE 802.1C authentication
- Microsoft: Protected EAP (PEAP)
- Select Authentication Method:
- Secured password (EAP-MSCHAP v2)
- specify authentication mode:
- User authentication
I try this configuration but without success:
Thank you for advice, Petr
