    NAME

    
    
    ng_tee
    
     - netgraph ``tee'' node type
    
     
    

    SYNOPSIS

       #include <sys/types.h>
       #include <netgraph/ng_tee.h>
     

    DESCRIPTION

    The tee node type has a purpose similar to the tee(1) command. Tee nodes are useful for debugging or ``snooping'' on a connection between two netgraph nodes. Tee nodes have four hooks, right left right2left and left2right All data received on right is sent unmodified to both hooks left and right2left Similarly, all data received on left is sent unmodified to both right and left2right

    Packets may also be received on right2left and left2right if so, they are forwarded unchanged out hooks right and left respectively.  

    HOOKS

    This node type supports the following hooks:

    right
    The connection to the node on the right.
    left
    The connection to the node on the left.
    right2left
    Tap for right to left traffic.
    left2right
    Tap for left to right traffic.

     

    CONTROL MESSAGES

    This node type supports the generic control messages, plus the following.

    NGM_TEE_GET_STATS
    Get statistics, returned as a struct ng_tee_stats
    NGM_TEE_CLR_STATS
    Clear statistics.

     

    SHUTDOWN

    This node shuts down upon receipt of an NGM_SHUTDOWN control message, or when all hooks have been disconnected. If both right and left hooks are present, node removes itself from the chain gently, connecting right and left together.  

    SEE ALSO

    tee(1), netgraph(4), ngctl(8)  

    HISTORY

    The node type was implemented in Fx 4.0 .
