somewhat ot: Check radius server name on linux supplicant
Hi, I'm stuck with a problem to which I haven't found an easy solution. Let's say we use either EAP-PEAP or EAP-TTLS. Both on Windows you cave ways to check not only ca certificate but also radius server name. I've tried: *NetworkManager: It can't check radius server name. *wicd: You could use customized scripts but make things harder and replace NetworkManager which is the default network tool on modern distros. *kwlan: It's like wicd an more KDE oriented. *wpasupplicant: It can check server name! But also on Fedora 10 I haven't found a way for NetworkManager apply its config file. Mostly "modern" and end users distros don't pay attention to wpasupplicant config file. On Windows (and I am not presicely a MS fan) you can check server name either by itself or by SecureW2. On Mac it prompts you showing radius server name. Sadly, I haven't found on Linux to check radius server name. I fear this: Let's say I have a radius server which use a certificate signed by WhateverSign. You get a certificate signed by WhateverSign too. You use a trustable ca certificate, don't you? Well, you config a cheating Access Point. Then a user come and connect to that cheating Access Point. Please tell me if that risk exists and if is wothy of worrying. If it is, how I can do for check radius server name on modern distro Linux? Thanks in advance and happy new year!!!! -- -- Open Kairos http://www.openkairos.com Watch More TV http://sebelk.blogspot.com Sergio Belkin -
hi, its down to the supplicant to have the option and ability to do these checks. Sure, most of them have a 'is cert okay'? option but if you've chosen to use a public auth then anyone else can get a cert signed by that auth and start playing around...which is a weakness. I'd certainly recommend using the server name check.... and since we are discussing Open Source and GPL software etc why not contact the authors of your favourite GUI for Linux and get the feature implemented? The underlying software that they call/use almost certainly has the ability - the GUI just hasnt got the option coded into it alan
