Hi All,
Sorry, this is going to be a short introductory message rather than a
full report initially due to lack of information.
I seem to be having problems with a new AMD64 'Firewall' I am building -
the last part of the puzzle being configuring at least 1 VPN tunnel.
From what I can gather racoon is the defacto for setting up IPSec
tunnels on FreeBSD. (I am still a relative newcomer to BSD being a
Linux/Solaris fan to date - must say I am impressed)
...anyhow to the problem...
Installation of the OS was from 5.3/amd64 CD's
Kernel has been recompiled:
FreeBSD desperado.sorbs.net 5.3-RELEASE-p4 FreeBSD 5.3-RELEASE-p4 #0:
Tue Jan 11 17:08:16 EST 2005
root@desperado.sorbs.net:/usr/obj/usr/src/sys/DESPERADO amd64
(everything pretty much standard, will make config available if
requested - IPFIREWALL is enabled)
racoon compiled and installed from source (via Ports)
Upon running of the binary the kernel will instantly trap a page fault
which begins:
Fatal Trap 12: Page fault while in kernel mode
fault virtual address = 0xffffffffc93009fc
fault code = supervisor read, page not present
I have recompiled the kernel with KDB and KDB_UNATTENDED however it
appears the machine is totally locked in this state - it will not
automatically reboot, it will not respond to [CTRL-ALT-ESC] it will not
even respond to [CTRL-ALT-DEL] - the only thing it will respond to is
"the big red button" ;-)
I have told it to save cores, however so far no cores. The crash is
reproducible everytime. The fault process is recorded as racoon.
Any suggestions on solving or debugging this further would be greatly
appreciated.
The machine is rack mounted and without remote management card so
getting the rest of the trace information is not going to be easy.
Regards,
