o [Nping] See whether --echo-client mode really requires root, and
remove that restriction if not.
Nping does need root access for echo mode (for both client and server
roles). This is because the protocol requires the client to provide
the server with details about the packets that are going to be
transmitted. When Nping is run in unprivileged mode, most of that
information cannot be accessed as it is the OS who crafts network
layer and transport layer headers.
If you need a more elaborate answer, please let me know.
What kind of information? What is the client unable to provide with, for
nping --echo-client "public" --tcp-connect server
What phase of the connection does it send this information in?
