Bug Description
I badly need 'NOTRACK' because of very heavy traffic (DNS recursive lookup requests) so I've decided to disable connection tracking for these packets. However the domumented (iptables man page) NOTRACK target does not work (on Gutsy, and dapper it seems to be OK). What can I do? I can't reboot/update/etc running machines at the moment.
I've tried this command:
iptables -t raw -A PREROUTING -p udp -m udp --dport 53 -j NOTRACK
Result of that command on 64 bit Edgy (kernel is 2.6.17-10-server):
iptables: Unknown error 184467440737095
On 32 bit Edgy (kernel is 2.6.17-12-server):
iptables: Unknown error 4294967295
On 32 bit Feisty:
iptables: No chain/target/match by that name

Newer distros are not affected (it seems) so I change status to 'fix released'.
