I need some assistance here....
My headache is caused by a Compaq Armada E500 notebook running FreeBSD
4.2-RELEASE (kernel config at the bottom of this message) and with the
mpd-netgraph port installed (mpd-3.2).
The machine always panics shortly after setting up a VPN link with a
Cisco 7140-2FE (with Integrated service module for H/W encryption and
running IOS EGR Software Version 12.1(4)E)
Before I could even set up the connection, I had to remove the
following lines from
/usr/ports/net/mpd-netgraph/work/mpd-3.2/src/pptp_ctrl.c :
if (hdr->resv0 != 0) {
Log(LG_PPTP, ("pptp%d: non-zero reserved field in header", c->id));
goto abort;
}
because (hdr->resv0 != 0) would always yield true. Is the Cisco not
speaking proper pptp here ?
my /usr/local/etc/mpd/mpd.conf looks like this :
default:
load vpn
vpn:
new vpn vpn
set iface disable on-demand
set iface idle 0
set bundle disable multilink
set bundle authname "********"
set bundle password "********"
set link yes acfcomp protocomp
set link disable pap chap
set link accept chap
set link keep-alive 10 75
set ipcp yes vjcomp
set ipcp ranges 157.193.33.4/16 157.193.46.4/16
set bundle enable compression
set ccp yes mppc
set ccp yes mpp-e40
set ccp yes mpp-e128
set bundle enable crypt-reqd
set ccp yes mpp-stateless
open
and here's my /usr/local/etc/mpd/mpd.links :
vpn:
set link type pptp
set pptp self 157.193.55.252
set pptp peer 157.193.46.4
set pptp enable originate incoming outcall
When I launch mpd, the link comes up, but a few seconds later, the
machine panics. I followed section 13.13. of the FreeBSD FAQ
(http://www.freebsd.org/FAQ/hackers.html#KERNEL-PANIC-TROUBLESHOOTING)
to give as much as possible information regarding this panic :
