Hello,
I applied the patch shown below to /usr/src/usr.sbin/ppp/fsm.c. It was not
actually affecting anything but I got tired of seeing endless error messages
in the log file. I don't know if the problem is with ppp or with Trumpet 2.0B
(a Windows PPP driver), but ppp was sending echo request packets with its
magic number and expecting a reply with the magic number that Trumpet had
previously requested. Instead, Trumpet simply sends a reply packet with the
same magic number it got in the request packet.
