|
This is user process \fIPPP\fR software package. Normally, \fIPPP\fR
|
1995-02-26 12:18:08 +00:00
|
|
|
is implemented as a part of kernel and hard to debug and/or modify its
|
1995-03-11 16:36:30 +00:00
|
|
|
behavior. (i.e. pppd) However, in this implementation, \fIPPP\fR is
|
|
|
|
implemented as a user process with the help of tunnel device driver.

1995-02-26 12:18:08 +00:00
|
|
|
o Provide interactive user interface. Using its command mode, user can
|
|
|
|
easily enter commands to establish the connection with the peer, check
|
|
|
|
the status of connection, and close the connection. And now, all
|
|
|
|
functions has password protected if describe your hostname/password in
|
|
|
|
secret file or exist secret file itself.

|
|
|
.TP 2
|
1995-02-26 12:18:08 +00:00
|
|
|
o Supports both of manual and automatic dialing. Interactive mode has
|
|
|
|
``term'' command which enables you to talk to your modem
|
|
|
|
directory. When your modem is connected to the peer, and it starts to
|
|
|
|
speak \fIPPP\fR, \fIPPP\fR software detects it and turns into packet
|
|
|
|
mode automatically. Once you have convinced how to connect with the
|
|
|
|
peer, you can write chat script to define necessary dialing and login
|
|
|
|
procedure for later convenience.

|
|
|
.TP 2
|
1995-02-26 12:18:08 +00:00
|
|
|
o Supports on-demand dialup capability. By using auto mode, \fIPPP\fR
|
|
|
|
program will act as a daemon and wait for the packet send to the peer.
|
|
|
|
Once packet is found, daemon automatically dials and establish the
|
|
|
|
connection.

|

ifilter for incoming packet, ofilter for outgoing packet, dfilter to

define dialing trigger packet and afilter to keep alive a connection

packet flow over the \fIPPP\fR link.

To play with demand dialing, you must use -auto option. Also, you
|
|
|
|
must specify destination label with proper setup in ppp.conf. It must
|
|
|
|
contain ``ifaddr'' command to define peer's IP address. (refer

Each ppp has associated port number, which is computed as "3000 +

tunnel_device_number". If 3000 is not good base number, edit defs.h.

When packet toward to remote network is detected, \fIPPP\fR will take

|
dialing action and try to connect with the peer. If dialing is failed,
|
1995-03-11 16:36:30 +00:00

program will wait for 30 seconds. Once this hold time expired, It's

\fIPPP\fR uses IPCP to negotiate IP addresses. Each side of node
|
|
|
|
informs IP address that willing to use to the peer, and if requested
|
|
|
|
IP address is acceptable, \fIPPP\fR returns ACK to
|
|
|
|
requester. Otherwise, \fIPPP\fR returns NAK to suggest the peer to use
|
|
|
|
different IP address. When both side of nodes agrees to accept the
|
|
|
|
received request (and send ACK), IPCP is reached to open state and
|
|
|
|
network level connection is established.

This is all right, when each side has pre-determined IP address.
|
1995-02-26 12:18:08 +00:00

|
|
However, it is often the case one side is acting as a server which
|
|
|
|
controls IP address and the other side should obey the direction from
|
|
|
|
him. In order to allow more flexible behavior, `ifaddr' command

allows user to specify IP address more loosely.

|
If you try to connect to Network Provider, you should consider enough
|
|
|
|
both my and his IP address. They may assign both/one of address
|
|
|
|
dynamically when ppp is connected. The IP address which you did set up
|
|
|
|
is just assumption when you set up ppp as dial-on-demand mode (-auto)
|
|
|
|
that is required them before connecting. So just trigger packet in
|
|
|
|
dial-on-demand will be lost.
