ng_echo —
netgraph echo node type
#include
<netgraph/ng_echo.h>
The
echo node type reflects all data and control
messages back to the sender. This node type is used for testing and debugging.
A
echo node accepts any request to connect,
regardless of the hook name, as long as the name is unique.
This node type supports only the generic control messages. Any other control
messages are reflected back to the sender.
This node shuts down upon receipt of a
NGM_SHUTDOWN control message, or when all
hooks have been disconnected.

ng_echo node type was implemented in
