Dear All,
I have been trying to use ipfilterd on a Silicon Graphics Origin 200,
Irix 6.4 machine. No matter how permissive the rules are, once I start the
deamon (with '/usr/etc/ipfilterd -d') all incoming packets are blocked. I
suspect the reason for this behaviour is that the loopback gets blocked
(because even commands like 'ps -elf' (issued from the console) do not
respond). I have tried an exhaustive combination of loopback (un)filtering
rules like :
accept -i lo0
accept -i lo0 1
accept ip.dst localhost or ip.src localhost
accept between localhost localhost
accept ip.src localhost or ip.dst localhost
,but to no avail. Even with only two rules :
accept -i lo0
accept -i ef0
the machine still hangs. Once the machines gets to this state, I can't
even 'reboot' or 'shutdown', so I have to hit the hardware reset button.
I'm definitely missing something here, but after 6 or 7 hardware reboots,
any piece of advice would be greatly appreciated.
Thanks,
Nicholas
