Hi,

Where I can enable syn cookie .
SYN Cookie is activated when the SYN flood attack threshold is exceeded ?


Thanks

for syn cookies an activate of '0' is probably the best choice as syn cookies are an intelligent way of preventing 'bad' syn requests so can be used even at low activity

 

if 'random early drop' is chosen instead, the activate rate should be very high, close to where the amount of syn packets could become critical, as there is no reason to start discarding packets if there is very low activity

Hi,

When the syn cookie will be activated?

Thanks

Number in 'Activate' field. 0 is quite good choice.
