iam using nc tool to test connection to port 1813 of my freeradius server
and iam getting this error on freeradius debug mode:

/usr/bin/nc -vnzu  freeradiusIP 1813

Receive - Invalid data from NASIP: Expected at least 4 bytes of header
data, got 1 bytes

any one have an idea how to send 4 bytes of header data with nc tool?
