Regarding DHCP Server Supporting RFC 4014


Dear All,

I want to know whether any DHCP Server is there which is supporting RFC 4014. I have tried to search this thing in ISC DHCP Server but found that they have not implemented it upto now.

Below are the reference for RFC and ISC DHCP implementionation point.

https://lists.isc.org/pipermail/dhcp...9-December.txt
http://www.rfc-editor.org/rfc/rfc4014.txt

So please let me know is there any dhcp server or any plugin through which we can achieve functionality of RFC 4014.

Regards,
Bhushan Karia

RFC4014 regards using Radius attributes with DHCP. If you tried to look this up, you would see that the FreeRADIUS server supports this functionality:

rfc4014 support

I made a patch to isc dhcp server 4.3.2 so that it supports rfc4014.
It keeps the radius attributes in the lease assigned.
It can answer to requests by dhcp leasquery or omapi with the
radius attributes. In particular it can answer with the User-Name
obtained for 802.1x authenticated clients.
i cannot post the url where the patch is available because this is my first post
here and the rules for this blog dont allow me to post links.
write to me for details.

eg . small python script using pypureomapi queries dhcp server and gets back
username(get-ip-l : get-ip-lease trough omapi)

$PYPUREOMAPI/get-ip-l 169.254.1.183
ip 169.254.1.182 mac 00:12:22:33:77:89 User-Name = kitten

I took the simplest road to store all radius attributes in one hex
option as in this example lease, it remains under the responsability of the
clients to decode them :

lease 169.254.1.183 {
starts 4 2015/05/28 06:04:23;
ends 4 2015/05/28 06:09:23;
cltt 4 2015/05/28 06:04:23;
binding state active;
next binding state free;
rewind binding state free;
hardware ethernet 00:12:22:33:77:89;
option agent.circuit-id "cir 123";
option agent.radius-attributes 1:8:6b:69:74:74:65:6e;
}

write to me for the simple python script querying for usernames.
