ovaj patch treba primjeniti http://redmine.bring.out.ba/attachments/1670/tomato123-vpn-src.patch.zip

uh ja sam ovo zezno skroz

pppd je kod postojećeg tomato-a 2.4.5

tako da ovim radim praktično downgrade

kod ovog 2.6 bringout tomato-a pptp-1.7.1 dok je na ovm patch-u 1.7.0

About MPPE and MPPC¶

http://mppe-mppc.alphacron.de/

MPPE stands for Microsoft Point-to-Point Encryption. It is a protocol designed for transfering encrypted datagrams over point-to-point links. See RFC3078 and RFC3079 for details.

MPPC stands for Microsoft Point-to-Point Compression. It is a protocol designed for transfering compressed datagrams over point-to-point links. The MPPC algorithm uses an LZ based algorithm with a sliding window history buffer. See RFC2118 for details.

Although the module's source code is completely free, MPPC itself is patented algorithm. Patent for Microsoft PPC is holded by the Hifn Inc. This is obvious ;-). Furthermore, MPPE uses RC4¹ encryption algorithm which itself isn't patented, but RC4 is trademark of RSA Data Security Inc. To avoid legal problems, US citizens shouldn't use this module.

OK, you have been warned, now you can do whatever you want.

MPPE/MPPC violate Compression Control Protocol: when decompression error occurs, receiver sends CCP ResetReq, sender resets the compressor but doesn't send CCP ResetAck which it should do if it would be fully CCP compliant. In my opinion it's very funny - probably guys from Hifn Inc. didn't want to pay royalties to Motorola which holds patent on this "technology". ;-) I love software patents. ;-)
Why have I written this module?

Besides Stac LZS, MPPC seems to be the most common compression algorithm used in (remote/network) access servers. On the one hand Internet Service Providers often set up their AS to support only the two mentioned algorithms and on the other hand AS often support only those algorithms - in my opinion this is result of implementation MPPC/MPPE and LZS in silicon. See http://www.hifn.com if you want to know more or if you want to buy such a chip. So they are de facto standards; Hifn's marketroids call them even industry standards. :-) At the client side, MPPE/MPPC is of course supported by Microsoft operating systems.

Some day, digging in the Net, I found MPPE implementation at http://mirror.binarix.com/ppp-mppe/.[2] I thought that it would be good to complete that code with MPPC and make it freely available. So I wrote MPPC part and added support for 56 bit keys in MPPE.
