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?

+Just a few quick notes.
+
+MPPE support was started by Árpád Magosányi <mag@bunuel.tii.matav.hu> in 1994,
+and was finished by Tim Hockin, Cobalt Networks Inc. <thockin@cobaltnet.com>
+in 1999. If you helped, and I don't know it (which could be) please notify
+the maintainer of this code, and it will be rectified. As far as I know, only i
+Linux is supported (sorry - it's all we had available).
+
+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. Rc4 is owned by
+RSA Data Security, and you may have to pay to use it, or not use it at all,
+depending on your place of residence. No author listed in this file claims
+any responsibility for misuse of this software. Copyright for some code is
+owned by Eric Young (see ./linux/rc4.h for details). Depending on where you
+got this code from (either in patch or tar.gz form), you may need to obtain
+the actual rc4 code from a different site. The implementation of rc4 found in
+the SSLeay package, by Eric Young, version 0.6.6. This package can be found
+at ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL/. Newer versions than 0.6.6 may
+require some minor source code or header file changes. Once obtained, copy
+rc4.h and rc4_enc.c to the linux/ subdir of this package.
+
+This 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?
+
+That said, it seems to work pretty well, for what it is. MSChap-v2 support
+was added by someone along the way, and MPPE needed some finishing. It
+appears to work with Windows (tm) clients, with encryption specified.
+
+How to use it:
+* Compile this pppd, and teh associated kernel modules.
+* Add +chapms and/or +chapms-v2 to your pppd command line.
+* Add mppe-40 and/or mppe-128 and/or mppe-stateless to your pppd command line.
+* Either load ppp_mppe.o manually or put this line in your /etc/conf.modules.
+ alias ppp-compress-18 ppp_mppe
+* Go for it.
+
+
+For further reading:
+ Use the source, Luke.
+ draft-ietf-pppext-mppe-03.txt (any RFC site should have this)
