Cyan: bluegrass*, black soybeans, Asian dayflower (commelina communis) …Developers use virtualenv to manage multiple development environments半梦半醒 - 南征北战NZBZThe sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.HTTP slow attack is to use the normal interaction mechanism of HTTP protocol to establish a connection with the target server first, and then keep the connection unreleased for a long time. If an attacker continues to establish such a connection with the target server, the available resources on the target server will be exhausted and normal services cannot be provided.二十世纪三十年代的中国，鱼龙混杂，各国列强也虎视眈眈，江湖乱世，风起云涌。二十年前，三个热血青年，唐英明，黄大为，胡南，歃血结义，立志闯出一番天地。然而，一次爆炸后，一切开始变的不同。VividLight
