-# Updated 97/06/13 to livingston-radius-2.01 miquels@cistron.nl
-#
-#	This file contains dictionary translations for parsing
-#	requests and generating responses.  All transactions are
-#	composed of Attribute/Value Pairs.  The value of each attribute
-#	is specified as one of 4 data types.  Valid data types are:
-#
-#	string - 0-253 octets
-#	ipaddr - 4 octets in network byte order
-#	integer - 32 bit value in big endian order (high byte first)
-#	date - 32 bit value in big endian order - seconds since
-#					00:00:00 GMT,  Jan.  1,  1970
-#
-#	Enumerated values are stored in the user file with dictionary
-#	VALUE translations for easy administration.
-#
-#	Example:
-#
-#	ATTRIBUTE	  VALUE
-#	---------------   -----
-#	Framed-Protocol = PPP
-#	7		= 1	(integer encoding)
-#
-
-# The dictionary format now supports vendor-specific attributes.
-# Vendors are introduced like this:
-#
-#	VENDOR vendor_name vendor_number
-#
-# For example:
-#
-#	VENDOR RoaringPenguin 10055
-#
-# Vendor-specific attributes have a fifth field with the name of the
-# vendor.  For example:
-#
-#       ATTRIBUTE RP-Upstream-Speed-Limit 1 integer RoaringPenguin
-#
-# introduces a Roaring Penguin vendor-specific attribbute with name
-# RP-Upstream-Speed-Limit, number 1, type integer and vendor RoaringPenguin.

-"uname -r", "uname -s" and "uname -m" results with the "UNAME_R", "UNAME_S"

-This patch implements the "ip-up-script" and "ip-down-script" options which

-
-These options default to _PATH_IPUP and _PATH_IPDOWN to retain the

-pppd: Close already open ppp descriptors
-
-When using the kernel PPPoE driver in conjunction with the "persist" option,
-the already open descriptor to /dev/ppp is not closed when the link is
-reestablished. This eventually leads to high CPU load because the stray 
-descriptors are always reported as ready by select().
-
-This patch closes the descriptor if it is already open when establishing a
-new connection. It originated from the Debian project.

-
-When the option is set, all leading chars up to and including the last

-pppoatm: Allow wildcard ATM devices
-
-When operating pppd's pppoatm plugin with an USB ADSL modem, e.g. an
-Alcatel Speedtouch, the ATM device number might change when the modem is
-reconnected to the USB port or when the host controller resets the USB
-device.
-
-This patch allows to specify the ATM device as wildcard which gives
-enough flexibility to cope with changing device names.

-pppd: Allow specifying ipv6-up and ipv6-down scripts
-
-This patch implements the "ipv6-up-script" and "ipv6-down-script" options
-which allow to specify the path of the ipv6-up and ipv6-down scripts to call.
-
-These options default to _PATH_IPV6UP and _PATH_IPV6DOWN to retain the
-existing behaviour.
-
-The patch originated from the Debian project.

-pppd: Watch out for time warps
-
-On many embedded systems there is no battery backed RTC and a proper system
-time only becomes available through NTP after establishing a connection.
-
-When the clock suddenly jumps forward, the internal accounting (connect time)
-is confused resulting in unreliable data.
-
-This patch implements periodic clock checking to look for time warps, if one
-is detected, the internal counters are adjusted accordingly.

-Two new options are introduced; "precompiled-pass-filter" specifies a pre-

-pppd: Retain foreign default routes on Linux
-
-On Linux, when pppd attempts to delete its default route it does not fill
-the rt_dev field of the struct rtentry used to match the system default route.
-As a consequence, pppd happily deletes any default route even if it belongs
-to another interface.
-
-This patch makes pppd fill out the rt_dev field so that only own default
-routes are ever matched.

-pppd: Fill in default gateway on Linux
-
-On Linux, when pppd creates the default route, it does not set the peer
-address as gateway, leading to a default route without gateway address.
-
-This behaviour breaks various downstream programs which attempt to infer
-the default gateway IP address from the system default route entry.
-
-This patch addresses the issue by filling in the peer address as gateway
-when generating the default route entry.

-+.SH NAME
-+pptp.so \- PPTP VPN plugin for
-+.BR pppd (8)
-+.SH SYNOPSIS
-+.B pppd
-+[
-+.I options
-+]
-+plugin pptp.so
-+.SH DESCRIPTION
-+.LP
-+The PPTP plugin for pppd performs interaction with pptp kernel module
-+and has built-in call manager (client part of PPTP).
-+It pasees necessary paremeters from \fIoptions\fR into kernel module 
-+to configure ppp-pptp channel. If it runs in client mode, then additionally 
-+call manager starts up. PPTPD daemon automaticaly invokes this plugin
-+in server mode and passes necessary options, so additional configuration
-+is not needed.
-+
-+.SH OPTIONS for client mode
-+The PPTP plugin introduces one additional pppd option:
-+.TP
-+.BI "pptp_server " server " (required)"
-+Specifies ip address or hostname of pptp server.
-+.TP
-+.BI "pptp_window " packets " (optional)"
-+The amount of sliding window size. 
-+Set to 0 to turn off sliding window.
-+    to 3-10 for low speed connections.
-+    to >10 for hi speed connections.
-+Default is 50
-+.TP
-+.BI "pptp_phone " phone " (optional)"
-+The phone string that sended to pptp server.
-+.SH USAGE
-+Sample configuration file:
-+.nf
-+plugin "pptp.so"
-+pptp_server 192.168.0.1
-+pptp_window 100
-+name myname
-+remotename pptp
