AltostratusHow to read a data in the UDP payload ?
I would like to use an UDP payload information (not header) to target a specific node. I need to read and handle this data (6 octets).
IP message example : Field "01007d" (radius).
...
Yes, your assumptions are correct. "UDP::collect 50" collects the first 50 octets of the payload (not including the IP/UDP headers).
For the binary scan, I would probably use "I" for the radius length since it is a 4 byte integer stored in big-endian format that you want.
So, try this:
binary scan [UDP::payload] x2I1 Radius_Length
