SSTP-CLIENT ------------------------------------------ Background: SSTP is Microsofts Remote Access Solution (RAS) for PPP over SSL. It can be used instead of PPTP or L2TP, and is only available with Windows Vista/7 connecting to a Windows 2008 Server. For further information on SSTP check out wikipedia's article on Secure Socket Tunneling Protocol. http://en.wikipedia.org/wiki/Secure_Socket_Tunneling_Protocol What is SSTP-CLIENT: SSTP-CLIENT is an SSTP client for Linux. It can be used to establish a SSTP connection to a Windows 2008 Server. This software is similar commandline and configuration as the pptp-client software. Features: * Establish a SSTP connection to a remote Windows 2k8 server. * Async PPP support (most distributions provide this). * Similar command line handling as pptp-client for easy integration. * IPv6 support * Basic HTTP Proxy support * Certficate handling and verification * SSTP plugin integration with NetworkManager v0.9 (available as separate package) SSTP-CLIENT on Ubuntu: It's pretty simple to integrate sstp-client into the Ubuntu / Debian distribution distribution. An example script is provided in support/peer-sstp-example.txt - Specify your MSCHAP password in /etc/ppp/chap-secrets Example Entry: SSTP-TEST\\JonDoe sstp-test 'testme1234!' * - Create a connect script in /etc/ppp/peers/sstp-test, similar to the example provided in ./support. Swap out user-name as appropriate - Start the script as: pon sstp-test Future: In the future we want to provide a SSTP server functionality as well. Code have been refactored such that this goal can be accomplishable. Also check out the TODO file. Help Wanted: I need help with various features, please drop me an email if you have some bandwidth to work on any of this. The TODO file should provide you with a list of wanted features. Compiling: To compile this on your favorite distribution make sure you have the development tools and headers available. This project depends on the PPP package, libevent and OpenSSL. For example: sudo apt-get install ppp-dev sudo apt-get install libevent-dev sudo apt-get install libssl-dev Important Links: * How to setup SSTP on windows 2008 server, technotes from Microsoft http://technet.microsoft.com/en-us/library/cc731352%28WS.10%29.aspx * The SSTP specification: http://msdn.microsoft.com/en-us/library/cc247338%28v=prot.10%29.aspx * A reference to the pptp-client software, this has much in common with the SSTP protocol. http://pptpclient.sourceforge.net/ * OpenSSL Examples: http://www.rtfm.com/openssl-examples/ * MicroTik have a working server and client version in the router software (as of March 2010). * SSToPer is another SSTP client, but doesn't support Async HDLC frames Other related software required to get this working: * OpenSSL (http://www.openssl.org) * PPPD (http://ppp.samba.org) * Libevent (monkey.org/~provos/libevent)
