PPTP Client
Overview PPTP Client is a Linux, FreeBSD, NetBSD and OpenBSD client for theproprietary Microsoft Point-to-Point Tunneling Protocol, PPTP. Allowsconnection to a PPTP based Virtual Private Network (VPN).Hosting provided by SourceForge. License | PPTP Client is licensed under the GNU General Public License (GPL) version 2 or later.PPTP Client was known as pptp-linux and was written by C. Scott Ananian.There have been many contributions by users of PPTP Client. PPP 2.4.2 and later contains MPPE support, added by Frank Cusack and others,that is licensed under a BSD without advertising clause license. The older and deprecated PPP-MPPE 2.4.0 and 2.4.1 contain MS-CHAP-v2and MPPE support that was added to PPP by Paul Cadach(paul@odt.east.telecom.kz). Two functions from OpenSSL were copied.Because of this, we must sayfor PPP-MPPE 2.4.0 and 2.4.1 that "this product includes cryptographicsoftware written by Eric A. Young (eay@cryptsoft.com)" and "this product includes software developed by theOpenSSL Project for use in theOpenSSL Toolkit. (http://www.openssl.org/)." 2008-05-14 | |
Getting Started So you'd like to run a PPTP tunnel from your Linux, FreeBSD, NetBSD or OpenBSD system? Need to connect to your employer's VPN? Just got ADSL? We suggest that you:- find documentation on our site that matches your distribution, or useour generic instructions,
- download and install the software according to the instructions,
- refer to our Diagnosis HOWTO ifyou experience problems,
- join our mailing list and ask for help, and
- contribute to the project by helpingus to improve the documentation or software.
Features - compatible with the Linux PPTP Server,
- compatible with Microsoft Windows VPN Server,
- compatible with many ADSL service providers,
- compatible with Cisco PIX,
- supports 128-bit stateless encryption using MPPE,
- supports on-demand or persistent tunnels using pppd psuedo-tty support,
- supports synchronous HDLC PPP encoding,
- supports reordering of out of order packets,
- runs on Linux, FreeBSD, NetBSD and OpenBSD.
Try it Although we have some distribution specific HOWTOs in our documentation section, they all boil downto these fundamental steps. To establish a tunnel to a PPTP server:- if your Linux kernel version is below 2.6.15, upgrade it or patchit to add MPPE support,
- if your Linux kernel does not have the ppp_mppe module, rebuild itto add MPPE support, enabling the CONFIG_PPP_MPPE kernel buildoption,
- install the PPTP client, preferrably from your Linuxdistribution,
- if the version of pppd is below 2.4.2, upgrade it,
- configure the client, start the tunnel, and configuring routing, by either:
- using the network manager pptp package,
- configuring a PPP connection to activate the PPTP program, asper the Configuration,by hand section of the DebianHOWTO, or
- downloading the (deprecated) pptpconfig configuration program,installing it, and running it, (our package).
