The canned requests sent by radpwtst have their attributes and their order 
hardwired, but there are a number of other options:

1. You can send an aribitrary type of request and an arbitrary set of 
attributes in any order with the -code flag:


radpwtst -noauth -noacct -code
    Access-Request User-Name=mikem NAS-Port-Type=Async

( you can also use the command line to attach any attribtues in any order to 
any of the canned requests)

2. You can send a raw packet whose data is in hex format in a file

cat /tmp/x.dat
01 ca 00 21 31 32 33 34 35 36 37 38 39 30 31 32
33 34 35 36 01 07 6d 69 6b 65 6d 3d 06 00 00 00
radpwtst -noauth -noacct -rawfile /tmp/x.dat

3. Or on the command line:
radpwtst -noauth -noacct -raw "01 ca 00 21 31 32 33 34 35 36 37 38 39 30 31 32 
33 34 35 36 01 07 6d 69 6b 65 6d 3d 06 00 00 00"

(clearly with the hex raw packets, you need to have some way of generating 
them in the first place. You can use -trace 5 to get the hex dunp of any 
packet that radpwtst generates)

Hope that helps.

Cheers.
