[pptp-server] PPTP error: "PTY read or GRE write failed"

[Dee Jay Randall]

  I get the following error when I try to get PoPToP to run
as pptp server to a winNT client. The NT side looks like it is
doing the right thing, but the third line from the bottom of
/var/adm/pptpd.log shows the server cutting the connection,
which the NT machine then pops up an error that it got cut off.

  I am running debian linux, kernel 2.0.29 and pppd 2.2.0f and pptp 0.9.2

  Any suggestions?
