.Sh NAME
|
|
.Nm pptp
|
|
.Nd Point-to-Point Tunneling Protocol daemon
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Ar hostname
|
|
[
|
|
.Op Ar --phone <phone number>
|
|
.Op Ar --quirks ISP_NAME
|
|
-- ]
|
|
.Op Ar pppd options
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
manages
|
|
a virtual private network (VPN) connection using Microsoft
|
|
PPTP protocols using IP GRE tunneling protocols.
|
|
.Nm
|
|
uses
|
|
.Xr pppd 8
|
|
on a pseudo-tty
|
|
to negotiate the connection with MS-CHAP authentication.
|
|
.Pp
|
|
Because
|
|
.Nm
|
|
uses GRE by using a raw IP socket, it will not work if your kernel has
|
|
the
|
|
.Xr gre 4
|
|
pseudo-device
|
|
configured.
|
|
.Pp
|
|
Build a kernel without "GRE encapsulation interface" support.
|
|
(NB: look in /usr/src/sys/conf/GENERIC for "pseudo-device gre".)
|
|
.Pp
|
|
The
|
|
.Ar hostname
|
|
parameter specifies which host should be contacted as the PPTP server.
|
|
Additional parameters are passed on to
|
|
.Ic pppd
|
|
and typically include a remote username or a file containing options.
|
|
.Pp
|
|
.Nm
|
|
must be run as root.
|
|
|
|
.Sh EXAMPLE
|
|
.Nm
|
|
.Ar hostname
|
|
.Op Ar pppd options
|
|
.Sh FILES
|
|
.Pa /var/run/pptp/<ip-address>
|
|
is created as a socket. It is used for communicating with an existing
|
|
PPTP call manager for a given remote server host.
|
|
.Pp
|
|
.Pa PREFIX/sbin/pptp-reconnect
|
|
can be used to (re)establish a pptp connection.

|
|
.Sh BUGS
|
|
.Nm
|
|
does not work with a GENERIC kernel, because
|
|
.Xr gre 4
|
|
conflicts with
|
|
.Xr pptp 8
|
|
protocol ip (47).
