[pptp-server] MPPE Modules on LinuxPPC

[Tom Sightler]

Hey guys, I've been trying to setup a PoPToP based PPTP server on a LinuxPPC box and have been unable to get encryption working.  Everything else seems to be fine, as long as I don't enable encrytion on the Client side everything works great, including MS-CHAP authentication, but as soon as I enable encryption, the connection still somes up, but I can't make it vary any traffic, even pings fail.

I've tried both 40 and 128 bit Stateless and non with both Win98 and WinNT clients.  No luck with any.  The ppp_mppe.o modules loads and shows as being in use whenever these connections are up, but the pppd keeps logging messages like the following:

Mar  4 13:12:46 janus pppd[9635]: MPPE 40 bit, non-stateless compression enabled
Mar  4 13:12:47 janus pppd[9635]: Unsupported protocol (0xd0ec) received
Mar  4 13:12:50 janus pppd[9635]: Unsupported protocol (0x9364) received
Mar  4 13:12:50 janus pppd[9635]: Unsupported protocol (0xd213) received

Mar  4 12:10:37 janus pppd[6555]: MPPE 40 bit, stateless compression enabled
Mar  4 12:10:37 janus pppd[6555]: Unsupported protocol (0xbb77) received
Mar  4 12:10:40 janus pppd[6555]: Unsupported protocol (0xea18) received
Mar  4 12:10:40 janus pppd[6555]: Unsupported protocol (0xb08) received
Mar  4 12:10:40 janus pppd[6555]: Unsupported protocol (0xf3b7) received

Could we possibly be seeing a endian problem here?  Does anyone know if there are protions of the ppp_mppe.c code that would need to be enfian aware?  I've seen this several times with other Linux code on PPC (and MIPS) since most code is written for Intel.

Anything else it could be?  I've tried everything I can think of.  I may try the Slirp implementation next.

Later,
Tom
