Litespeed backloq queue full..

[seyit]

Hi,

i just try to know how is going litespeed while on ddos attack..
i set up ubuntu with kernel 3.0 also i configuration ddos params on litespeed
i just tring http flood it goes fine.. But i got 1 problem..

while i try Syn fooding.. server is stuck..
backlog queue is full and 3way handshake is filled up..

here u see what happens.
root@litespeed:/etc# netstat -n -p TCP |grep SYN_RECV | wc -l
256

question is how can i increase backlog queue? . Because on linux its only 256 connection on default.. i want to increase this anyone know how it be ? or any configuration that i miss on litespeed ?

Thanks.
