/* enable */ - u_int32_t bits; /* config bits */ - u_char startkey[MPPE_KEY_LEN]; /* start key */ -}; - -.Ed -The -.Dv enabled -field enables traffic flow through the node. -The -.Dv bits -field contains the bits as negotiated by the Compression Control Protocol -(CCP) in PPP. -The -.Dv startkey -is only necessary if MPPE was negotiated, and must be equal to the -session start key as defined for MPPE. -This key is based on the MS-CHAP credentials used at link authentication time. -.It Dv NGM_MPPC_CONFIG_DECOMP -This command resets and configures the node for a session in the -incoming traffic direction (i.e., for decompression and/or decryption). -This command takes a -.Dv "struct ng_mppc_config" -as an argument. -.It Dv NGM_MPPC_RESETREQ -This message contains no arguments, and is bi-directional. -If an error is detected during decompression, this message is sent by the -node to the originator of the -.Dv NGM_MPPC_CONFIG_DECOMP -message that initiated the session. -The receiver should respond by sending a PPP CCP Reset-Request to the peer. -.Pp -This message may also be received by this node type when a CCP Reset-Request -is received by the local PPP entity. -The node will respond by flushing its outgoing compression and encryption -state so the remote side can resynchronize. -.El -.Sh SHUTDOWN -This node shuts down upon receipt of a -.Dv NGM_SHUTDOWN -control message, or when both hooks have been disconnected. -.Sh COMPILATION -The kernel options -.Dv NETGRAPH_MPPC_COMPRESSION -and -.Dv NETGRAPH_MPPC_ENCRYPTION -are supplied to selectively compile in either or both capabilities. -At least one of these must be defined, or else this node type is useless. -.Pp -The MPPC protocol requires proprietary compression code available -from Hi/Fn (formerly STAC). -These files must be obtained elsewhere and added to the kernel -sources before this node type will compile with the -.Dv NETGRAPH_MPPC_COMPRESSION -option. -.Sh BUGS -In PPP, encryption should be handled by the Encryption Control Procotol (ECP) -rather than CCP. -However, Microsoft combined both compression and encryption into their -``compression'' algorithm, which is confusing. -.Sh SEE ALSO -.Xr netgraph 4 , -.Xr ng_ppp 4 , -.Xr ngctl 8 -.Rs -.%A G.
