The Point-to-Point Protocol (PPP) provides a standard way to establish a
|
|
network connection over a serial link. At present, this package supports
|
|
IP and the protocols layered above IP, such as TCP and UDP.
|
|
|
|
This software consists of two parts:
|
|
- A NetBSD Loadable Kernel module, which establishes a network interface
|
|
and passes packets between the serial port, the kernel networking code
|
|
and the PPP daemon (pppd).
|
|
- The PPP daemon (pppd), which negotiates with the peer to establish the
|
|
link and sets up the ppp network interface. Pppd includes support for
|
|
authentication, so you can control which other systems may make a PPP
|
|
connection and what IP addresses they may use.
|
|
|
|
This version is patched to support MPPE:
|
|
MPPE - Microsoft Point-to-Point Encryption uses rc4 (40 or 128 bit) as a
|
|
bi-directional encryption algorithm. The keys are based on your MS-CHAP
|
|
authentication info, so you must use chapms or chapms-v2.
|
|
|
|
MPPE is NOT a particularly secure mode of operation. For maximum possible
|
|
security using MPPE, it is advised in the RFC's to use the highest mode of
|
|
encryption that is legal, and to enable stateless mode (which renogotiates
|
|
keys with every packet). Even with these precautions, MPPE is not very
|
|
secure, but anything is better than nothing, right?
