RE: [Help-gnu-radius] RE: Radius 1.1 3COM/USR support

[Azzopardi Konrad]

Dear Andrea,

Attached please find two traces. 3com_radius.eth is a trace showing what
I would like to achieve. gnu.eth is a trace for the gnu radius.

Specifically please look at 3com_radius.eth packet no.2 {Access
Response}. One vendor specific packet with attribute 0x9024 is composed
like this :

1a 12 00 00 01 ad 00 00 90 24 77 61 70 70 6f 6f 6c 31

1 byte for Attribute (1a)
1 byte for Attribute length {12}
4 bytes for Vendor Code (00 00 01 ad)
4 bytes for Vendor attribute {00 00 90 24}
8 bytes for string {77 61 70 70 6f 6f 6c 31}

The above is correct and it is what I want to achieve with my gnu radius
but look what's happening in gnu.eth packet 2. I am sending this
attribute via a script.

1a 10 00 00 01 ad 24 0a 77 61 70 70 6f 6f 6c 31

1 byte for Attribute (1a)
1 byte for Attribute length {10}
4 bytes for Vendor Code (00 00 01 ad)
1 byte for Vendor attribute (24)
1 byte for Vendor attribute value length (0a)
8 bytes for string {77 61 70 70 6f 6f 6c 31}

Clearly the traces are different and since the latter is constructed
according to standard and not to 3com standard clearly the 3com client
will not understand the message.

Is there a way how to make gnu radius compose the packet according to
3Com standard.

Can you send me the trace you got form ethereal? I mean the binary dump,
plz?
