802.1X and Radius server vs Nocat Project

[Fernando Cabrera]

Hello!!

I have a wireless card in my Red Hat box running as master mode with the 
hostap. I want to authenticate the users who connects to my computer. I 
have heard about 802.1X and Radius server in this mailing list, but i have 
found other utility to do that. This is the Nocat project http://nocat.net/ 
. You can see a brief guide in this link 
http://verma.sfsu.edu/users/wireless/bawug-july-2002.pdf

I have looked the nocat page and i guess it?s very similar to 802.1x, even 
you can give different kinds of access to your netwok, depending of the 
privilege of the user. I want to know if you can do that with 802.1x and 
Radius and if there are any other different between them.

Which one do you recommend me??

Thanks
