From: Matt Domsch <Matt_Domsch@dell.com> The patch below implements the Microsoft Point-to-Point Encryption method as a PPP compressor/decompressor. This is necessary for Linux clients and servers to interoperate with Microsoft Point-to-Point Tunneling Protocol (PPTP) servers (either Microsoft PPTP servers or the poptop project) which use MPPE to encrypt data when creating a VPN. This patch differs from the kernel_ppp_mppe DKMS pacakge at pptpclient.sourceforge.net by utilizing the kernel crypto routines rather than providing its own SHA1 and arcfour implementations. Minor changes to ppp_generic.c try to prevent a link from disabling compression (in our case, the encryption) after it has started using compression (encryption). Feedback to <pptpclient-devel@lists.sourceforge.net> please. Signed-off-by: Matt Domsch <Matt_Domsch@dell.com> Cc: James Cameron <james.cameron@hp.com> Cc: "David S.
