[pptp-server] pts Problem

[Dave Hahn]

Trying to get pptp running on a RedHat 6.0 installation.  The recompile
of pppd went as did the install.  However, when trying to connect
problems start.

Pertinent log info:
Aug 23 15:37:12 proxy pptpd[2261]: CTRL: Client 216.168.67.212 control
connection started
Aug 23 15:37:12 proxy pptpd[2261]: CTRL: Starting call (launching pppd,
opening GRE)
Aug 23 15:37:43 proxy pptpd[2261]: GRE:
read(fd=4,buffer=804d194,len=8196) from PTY failed: status = -1 error =
Input/output error
Aug 23 15:37:43 proxy pptpd[2261]: CTRL: PTY read or GRE write failed
(pty,gre)=(4,5)
Aug 23 15:37:43 proxy pptpd[2261]: CTRL: Client 216.168.67.212 control
connection finished

I'm guessing that the problem comes from the PTY read of GRE write
failed line.

How can I go about fixing this issue?
