Hearing this, Grandma Lily secretly shed tears.This leads to an obvious potential DoS attack. Incoming SYN packets will be allocated too many TCB and the host's kernel memory will be exhausted. In order to avoid this memory depletion, the operating system usually associates a "backlog" queue parameter with the listening interface, which maintains both the upper TCB number of connections and the SYN-RECEIVED state. Although this scheme protects the host's available memory from attack, the backlog queue itself brings a (small) source of attack. When there is no space in the backlog, it is impossible to respond to new connection requests unless the TCB can be recycled or removed from the SYN-RECIEVE state.嗯，我记下了，是春风出版社。四分天下？项羽心中一叹，没想到当初自己一家独大的时代已经彻底过去了，四分天下已经是一种趋势了。In the above figure, when deleting the corresponding rules, the-D option is still used.-D INPUT means deleting the rules in the INPUT chain.
