Debian as a 802.1X authentificator
location: linuxquestions.com - date: June 4, 2014
Hi everyone I'm new on this forum, I hope that I won't break too many rules of your community.
I want to set up an example of 802.1X authentification with 3 virtual machines, an windows xp (supplicant), a linux debian used as a switch (authentificator) and windows server 2003 (authentification server).
As I'm posting this for a Linux community you can guess that I'm having trouble with the authentificator.
I can't find information on how set up this kind of service on Linux.
So I would like some help on which tools can I use on my debian to do this and how do I configure this tools.
Thank you a lot for reading my request, I hope you'll be able to guide me.
Have a good day.
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!

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
How to implement 802.1X network security?
location: ubuntuforums.com - date: June 19, 2009
If possible, I would like to put 802.1x security on my network. More security is better than less, so I figured why not try.
First, what do the various authentications mean--TLS, Tunneled TLS, PEAP?
Then I am supposed to find a user certificate, CA certificate and a Private Key somewhere on my system, but I have none of these files. How to create them or get them?
Network Manager forgets 802.1X wireless password after
location: ubuntuforums.com - date: November 9, 2009
Hi. The 802.1x wireless at my university is patchy -- I frequently lose it and get it back -- but that isn't the problem I'm reporting right now.
Sometimes, when my computer drops the wireless network, it isn't able to reconnect. In past versions of Ubuntu, all I had to do was disable and re-enable wireless. If I let it search for the wireless network too long, it would give up trying to connect. But now (9.10 Karmic Koala), I observe that when Network Manager gives up, it erases my 802.1x password for that network. Any ideas?
P.s. I looked up the log for Network Manager, and it looks like wpa_supplicant is deleting my password randomly. I don't know why, though. I've attached a portion of my daemon.log, starting at a point when I know the password was there. (I stripped out my hostname and username, of course.)
802.1x network manager no longer working under 13.04 64 bit
location: ubuntuforums.com - date: May 14, 2013
Did a fresh 64bit install and connection to a Ethernet with 802.1x is not working anymore. With 12.10 32 bit worked fine and upgrading from 12.10 to 13.04 32bit also worked fine.
But decided to do a fresh 64 bit install of 13.04 and 802.1x is not working now.
Authentication: Protected EAP
No CA Certificate
Inner Authentication: MSCHAPv2
When trying to use this sometimes network manager applet crashes.

Ubuntu 12.04 and 802.1x
location: ubuntuforums.com - date: July 19, 2012
So, I have an Ubuntu 12.04 machine I am trying to connect to my 802.1x wireless network. Let's call it SSID for example. So I enter all of my credentials, it connects and displays "SSID is connected" or whatever the usuall success message is. I am able to get to the Internet and all is well.
But here is my problem. It will say it is connected to SSID for about 5 minutes, and then it displays it being connected to another wireless network, usually the first one in the list of available. The only connection setting stored is the one for SSID, it is really not connected to that network at all. I have reinstalled completely and have had no luck.
Please advise of what I should do to fix this problem. Many thanks.
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:

My friend has Lenovo G8550 laptop, he installed Ubuntu 13.04 and unfortunately he cannot access his university wireless network, named "yildiz-net".
We tried different solutions but didn't succeed. Our last hope was this post.
We used the script mentioned in this post and all related information for his case is presented below.
We'd greatly appreciate if you can help us.

802.1x WEP PEAP MSCHAPv2
location: ubuntuforums.com - date: May 8, 2009
I have a problem with connecting to the wireless aps at my school.They use 802.1x WEP PEAP MSCHAPv2 and i use 9.04 Netbook Remix.
The problem is that i need to receive the CA certificate when i connect. The school has a guide for win xp where there is a checkbox that says: "Validate server certificate when connecting" which needs to be unchecked, but nothing in Ubuntu seems to do the trick.
