Hi all,
I am trying to use dummynet but my kernel enters in panic mode...
here follows a decsription of my configuration:
FreeBSD version: 2.2.8-R
Options in the kernel config file:
options IPDIVERT # Divert sockets
options DUMMYNET
options IPFIREWALL
options IPFIREWALL_DEFAULT_TO_ACCEPT #allow everything by default
dmesg output:
$ dmesg
FreeBSD 2.2.8-RELEASE #0: Mon Feb 15 20:09:11 CET 1999
eduros@lpacman.inria.fr:/usr/src/sys/compile/LPACMAN
CPU: Pentium Pro (199.31-MHz 686-class CPU)
...
de0: enabling 10baseT port
IP packet filtering initialized, divert enabled, default to accept,
logging disabled
DUMMYNET initialized (980901) -- size dn_pkt 48
After booting I try the following pipe configuration:
$ ipfw pipe 1 config delay 50ms
and when I enter the next ipfw command:
$ ipfw add pipe 1 ip from any to any
and the station simply reboots (kernel in panic mode)...
However the following commands work fine (and I get the expected
delays):
$ ipfw add pipe 1 ip from HostA to HostB
$ ipfw add pipe 1 ip from Net/mask to Host
It seems it is related to 'from any to any'
I believe I do not have to patch anything since the dummynet is included
in 2.2.8-R.
Is there anything I can do ?
Thanks a lot
Emmanuel Duros
