Sending attribute with sub-attributes

[David Peterson]

I am having issue with this portion of the dictionary.  The packet shows as
malformed and is for some reason sending two tlv's that seem to be mangled
or merged somehow.  Here is how I have this portion of my dictionary.wimax
setup.

ATTRIBUTE       WiMAX-R3-IF-Descriptor                  26   tlv

 

ATTRIBUTE       WiMAX-R3-IF-Name                                        26.1
string

ATTRIBUTE       WiMAX-R3-IF-ID                                          26.2
octets

ATTRIBUTE       WiMAX-PDFID                                             26.3
short

ATTRIBUTE       WiMAX-IPv4-addr                                         26.4
ipaddr

ATTRIBUTE       WiMAX-IPv4-Netmask                                      26.5
ipaddr

ATTRIBUTE       WiMAX-DGW-IPv4-addr                                     26.6
ipaddr

 

ATTRIBUTE       WiMAX-DHCP-Option                                       26.7
tlv

 

ATTRIBUTE       WiMAX-Ref-R3-IF-Name                            26.7.1
string

ATTRIBUTE       WiMAX-DHCP-Option-Container                     26.7.2
string

 

I am sending 

WiMAX-R3-IF-Name          = "vpws"

WiMAX-PDFID                       = 1

 

 

However the length of the attribute seems wrong at least according to
wireshark.

 

Any thoughts would be very helpful.

I think I may be getting closer.  What should I define this as in the
dictionary:

 


TLV ID

1 for Ref-R3-IF-Name TLV


Description

Reference name to bind the specified DHCP option with the particular
R3-IF-Descriptor/ Service Group - specific for Multi-host scenario.


Length

2 + Variable


Value

ASCII string

 

I am currently using "string" and getting an unhandled integer length (which
may just be a wireshark issue)

AHh ok great!  

 

It appears  I am on v2.2.  Should I be on 3.0 to support the sub-sub tlvs
needed for this NAS?

  Yes.  List them in order of attribute number, lowest to highest.

 

  Basically, the same order that they are in the dictionary.

  No... the pcap *viewer* you're using doesn't support the WiMAX attributes.

This is not surprising.  Wireshark grabbed the dictionaries from FreeRADIUS
a few years ago, and haven't updated them since.

$ radiusd -v
