If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.19世纪末的爱丁堡，在一个极度寒冷的冬天，痛苦的孕妇找到被人称作巫婆的玛德莲大夫（Marie Vincent 配音）。不久，一个孱弱的婴儿降临人间，但是这个小家伙的心都冻僵了，为此玛德莲帮他安装了机械心脏。孩子的生母不告而别，玛德莲将其作为亲生儿子抚养，并起名杰克（Mathias Malzieu 配音）。她告诫杰克不可以生气，避免强烈的情绪起伏，尤其要避免陷入爱恋。小杰克一天天长大，在他十岁的那年他首度来到镇上玩耍，并和命运中的天使邂逅。他的机械心脏出了故障， 冒出浓烟，他知道他恋爱了。从这一天起，杰克注定要踏上追寻爱情的征程……Aircraft to land: Approach the appropriate runway or open and flat area.

One thing must be said is that it is too long. The general soup pot in the home is definitely not applicable. If you want to use it, you need to buy a deep soup pot or a box with large capacity. I put it sideways all the way, which did not affect my use.
