Some notes on ubuntu (feisty)

Firestarter firewall not persistent after reboot

I just installed feisty on a box, installed firestarter, ran the gui and added some stuff to be blocked etc and I clicked the "ip address is assigned via dhcp". The firewall works fine until I reboot - after reboot there is no protection at all.

Now, it seems like firestarter created a file

/etc/dhclient-exit-hooks

just containing just the line

sh /etc/init.d/firestarter start

However, it seems like ubuntu is configured to look for this file in /etc/dhcp3 (I'm not quite sure about this) *or* to look for executables in /etc/dhcp3/dhclient-exit-hooks.d/ (I think it will run them all after dhclient obtains an ip.)

Anyway, here is a FIX to get a persistent (firestarter configured) firewall to be activated after reboot (i.e., when getting ip via dhcp):

Rename

/etc/dhclient-exit-hooks

/etc/dhcp3/dhclient-exit-hooks.d/firestarter

and then make it executable (using chmod +x).

Is this is a bug in ubuntu?
