[pptp-server] ppp_mppe

[Ralph Winslow]

Successful pptp users,

I've been following the procedure specified in 
http://www.moretonbay.com/vpn/releases/HOWTO-PoPToP.txt, and reached the
point where I should [rmmod ppp].  This fails

root at rjw# rmmod ppp
ppp: Device or resource busy

I tried to proceed like this:

root at rjw# lsmod
Module                  Size  Used by
ppp_deflate            40936   0  (autoclean)

3c59x                  19548   1 
root at rjw# insmod ppp_mppe
insmod: ppp_mppe: no module by that name found

so I rebooted, hoping that that would insmod my new ppp (and, hopefully,
mppe) module(s), but no joy.  The instructions up to that point seemed
to complete nicely and without error, except that I can't run pppoe
using the recommended script; I had to dump its output and create
my own run_pppoe script which looks like:

#!/bin/sh
/usr/bin/setsid /usr/sbin/pppd pty '/usr/sbin/pppoe -p .pppoe -I eth0 -T -m ' noipdefault noauth defaultroute hide-password nodetach  local mtu 1492 mru 1492 noaccomp noccp nobsdcomp nodeflate nopcomp novj novjccomp user fubardude at bellatlantic.net lcp-echo-interval 30 lcp-echo-failure 4 debug

because the "lcp-echo-interval 30 lcp-echo-failure 4" args weren't beeing
filled in by the standard startup script.  I believe that this is why
I have to use poff -a to shutdown pppoe, and that that's why the rmmod
ppp call fails (i.e. poff -a doesn't teardown correctly).  

I know that this is a lot of vague clues, but if anyone could suggest
some line of attack on this problem, I'd be very grateful.
