i m flooding an interface using hping with UDP packets .
I have a rule
iptables -A INPUT -p udp -j DROP
I can see all packets are getting dropped . i can see processor
utilization is high using "top" command and system becomes slow .
But while flooding , if i add rule
iptables -I INPUT -j ACCEPT .
still packets gets dropped .
But if i stop flooding and start hping again { with same rules } ,
packets are accepted .
Note : I am working on an embedded enviornement with 128kB of RAM .
any hints is really appreciated .
Thanks,
Ratheesh.
