DHCP Fingerprint and PS3

  • 1.  DHCP Fingerprint and PS3

    Posted Jun 13, 2012 09:54 PM

    Hi all,

    I have a bunch of fingerprints working but can't seem to figure out why the PS3 won't fingerprint. I lifted the dhcp-option from the debug just like the guide said but still can't get the fingerprint to work. Anyone have a PS3 fingerprint that they can send along?

     

    Here is what I've been trying: debug first than the line in the dev rule:

     

    Jun 13 21:21:49 :202536:  <DBUG> |dhcpdwrap| |dhcp| Datapath vlan986: REQUEST 28:0d:fc:70:5f:e0 reqIP=10.24.4.28 Options 36:0a01ff15 37:01030f06 3d:01280dfc705fe0 3c:50533300

     

    set role condition dhcp-option starts-with "01030f06" set-value xxx-wifixxx-mobile description "Playstation"

    In that case, your "starts-with" would be "3701030f06".  You have to remove the colon and concatenate (combine) the 37 with the rest of the string.

    I lifted the same fingerprint for PS3 and I cannot get it to work either. I'm still using MAC OUIs for the time being.

     

    My XBOX fingerprint is working great (370103060f).

    Tim,

     

    What did you observe for the PS3 Fingerprint?

    When I look in the controller under Authentication > User Rules, that dhcp-option rule has 0 hits and the mac address rules have quite a few. The dhcp-option rule is at the top of the list.

    I meant, how did you discover the DHCP fingerprint for the PS3?

    I used the same debug process as the original post and also verified with Wireshark running on the DHCP server.

    Okay.  Well we need to find out why it is not working.  There are sometimes 3 parameters that are part of the signatures and the key is to choose the right one and the right format.  If you did a capture and/or DHCP debugging you might have what you need, but the format may be incorrect.  Please consult the document here:  http://www.arubanetworks.com/wp-content/uploads/AOS-DHCP-FingerPrint-AppNote.pdf to ensure that the right parameter is being used.
