NAME

     ng_ip_input -- netgraph IP input node type

SYNOPSIS

     #include <netgraph/ng_ip_input.h>

DESCRIPTION

     The ip_input node type takes all received packets and queues them into the IP in input processing subsystem.

HOOKS

     An ng_ip_input node accepts any request to connect, regardless of the hook name, as long as the name is unique.

CONTROL MESSAGES

     This node type supports only the generic control messages.  Other control messages are silently discarded.

SHUTDOWN

     This node shuts down upon receipt of a NGM_SHUTDOWN control message, or when all hooks have been disconnected.

SEE ALSO

     netgraph(4), ngctl(8)

HISTORY

     The ng_ip_input node type was implemented in FreeBSD 5.0.

BUGS

     The ng_ip_input node type should probably keep some sort of statistics.

NG_HUB(4)						   BSD Kernel Interfaces Manual 						 NG_HUB(4)

NAME

     ng_hub -- packet distribution netgraph node type

SYNOPSIS

     #include <netgraph/ng_hub.h>

DESCRIPTION

     The hub node type provides a simple mechanism for distributing packets over several links.  Packets received on any of the hooks are for-
     warded out the other hooks.  Packets are not altered in any way.

HOOKS

     A hub node accepts any request to connect, regardless of the hook name, as long as the name is unique.

CONTROL MESSAGES

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

     NGM_HUB_SET_PERSISTENT
	  This command sets the persistent flag on the node, and takes no arguments.

SHUTDOWN

     This node shuts down upon receipt of a NGM_SHUTDOWN control message, or when all hooks have been disconnected.  Setting the persistent flag
     via a NGM_HUB_SET_PERSISTENT control message disables automatic node shutdown when the last hook gets disconnected.

SEE ALSO

     netgraph(4), ng_bridge(4), ng_ether(4), ng_one2many(4), ngctl(8), nghook(8)

HISTORY

     The ng_hub node type appeared in FreeBSD 5.3.
