[Chilli] dhcp client hostname

[Gergely Kiss]

Hi Tamás,

David wrote an article about using vendor-specific attributes to be
able to get the DHCP options from the clients (including the client's
hostname):

http://www.coova.org/node/118

I don't know if it's still a proposal or has been implemented already,
but taking a quick look at the source tells me the proposed DHCP
attributes are already included in the dictionary file:

http://dev.coova.org/svn/coova-chilli/doc/dictionary.chillispot

On the other hand, it seems the code does not use these attributes
anywhere, so I think you will need to change the source to get the
hostname as a RADIUS access request attribute.

Unfortunately, I'm not good enough at C++ programming to do the
coding, but basically you just need to fetch the hostname from the
DHCP request (DHCP option 12), store it in a property and pass it to
the RADIUS server when sending an access request packet during
authentication.

Gergely Kiss

Ps. én is magyar vagyok! :)
