AltostratusThanks for the irule and your reactivity !
The data I should retrieve in a payload is a radius Type/Length/Value attribute (variable position). So I must test several data.
I have some questions for confirmation (... It's my first use):
example . Radius/UDP Ethereal
-------
UDP / 69 51 81 66 07 14 00 85 8d a9 /end UDP

Are the following lines correct?
- To load the first 50 octets (for example) bytes of the payload
When CLIENT_ACCEPTED { UDP::collect 50 }
- If I want to read Radius Lenght : 007d (?)
binary scan [UDP::payload] x2a4 Radius_Lengh
Thank you for your assistance .
