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.一名长相清秀的男生路过驻足，看了几眼便说：这应该是模仿的颜体楷书，下笔遒劲因而气概凛然，颜真卿字迹的特点倒学的有几分模样。倘若有五千两余款，如此算下来，杨长帆能落个六百两上下。周青稍微一打听，就听人说道，这个张宇正天生就有大福缘，在一座荒山上，遇到一个道人，这个道人传他一卷道书、一粒大罗九转金丹、一把纯阳宝剑。EXAMPLE 2…,因此尹旭自信地坐在眼前，某种程度上已经抹煞了他汉王的面子。咿呀响声中，看着乳黄色的豆面从石磨四周流下来，他很开心。
