21: .Sh DESCRIPTION
22: .Nm
23: is a user mode PPP daemon using the
24: .Xr netgraph 4
25: networking system.
26: By using Netgraph,
27: .Nm
28: combines the robustness and flexibility of a user-mode PPP implementation
29: with the speed and reliability of kernel-mode packet forwarding.
30: All PPP negotiation is handled in user level code, while all data
31: intensive operations such as encryption, compression, and multi-link
32: framing are handled strictly in the kernel.
33: Mpd supports several link layer types, a fully event-driven modem chat
34: scripting language, and other features.
35: .Pp
36: .Nm
37: creates a
38: .Xr ng_ppp 4
39: netgraph node that is placed between a
40: .Xr ng_iface 4
41: netgraph interface one or more link layer devices,
42: performing multi-link PPP negotiation and encapsulation. In multi-link PPP a
43: .Ar bundle
44: is a collection of one or more
45: .Ar links
46: between two peers. Each link corresponds to some device (e.g.,
47: a modem), and each bundle corresponds to one netgraph interface.
48: The idea is to use all of the links, together connected to a remote
49: peer also performing multi-link PPP, to utilize their combined
50: bandwidth. Packets routed through the netgraph interface travel in
51: multi-link fragments over all of the links.
52: Each link is a normal PPP link and can deliver complete packets
53: as well, so redundancy is another benefit.
54: Attempts to connect two links in the same bundle to different peers,
55: or to a peer that is not configured for multi-link PPP, will fail.
56: .Pp
57: In general, everything is controlled by executing commands which are either
58: entered via the console command line or read from a configuration file. If
59: .Nm
60: is running as a background daemon, the console can be made accessible via
1.1.1.3 misho 61: .Xr telnet 1 .
1.1 misho 62: Since commands may apply to a single link, the console prompt always shows the
63: .Ar current bundle
64: or the
65: .Ar current link
1.1.1.3 misho 66: in that bundle.
67: On startup mpd run commands from the
68: .Ar startup
69: label of config file.
70: After that, if
71: .Ar configuration
72: is supplied, mpd looks config file for a matching label and runs the
73: corresponding commands.
74: If
75: .Ar configuration
76: is not supplied, mpd looks for label named
77: .Ar default .
