In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.　　泰瑞和鲍勃是新墨西哥两名无赖、腐败警察，靠勒索犯罪份子牟利。一次，欲通过雷吉谋取100万，不料黑道老大摩根黑吃黑卷走80万。泰瑞和鲍勃向摩根恐吓索求80万，又不料被摩根动用关系将二人踢出警局。接着，泰瑞、鲍勃杀向摩根老巢，一场西部牛仔式的枪战上演……杨长帆冲那位年迈的商人点头道：不错，我徽王府对于九州航路亦如此。来，把衣裳脱了，盖上被子。1924年秋，冯玉祥北京政变，御厨赵亮邦和师兄弟董家瑞、关少则被掳掠到奉系军阀的兵营做伙夫，几经波折逃出生天，师兄弟三人从此走上了不同的道路。赵亮邦回到苏南老家开淮扬菜馆，没过多久却因“通共”的罪名被二次充军，在那里遇到了师兄董家瑞，后又被红军俘虏，与小师弟关少则重逢，很快，赵亮邦回到了家乡。1937年南京大屠杀后，日军设庆功宴，师兄弟三人摒弃前嫌合作策划了宴会毒杀事件，但亲人却惨遭报复，妻子、父亲惨死，赵亮邦家破人亡。面对处于不同阵营的董家瑞和关少则的对立，看着他们为不同的信仰而战，赵亮邦一度束手无策，但历经战火洗礼，他终是在共产党人的指引下弃厨从戎，带着坚定的信念投入到革命洪流中去，并成为一名坚定的共产党人。Subject class, accept method, accept the object that will be accessed, getSubject () gets the property that will be accessed,
