In the example above, the-R option means modifying the specified chain, Using-R INPUT 1 means modifying rule 1 of the INPUT chain, Using-j REJECT means that the action of changing the first rule in the INPUT chain to REJECT. Note: In the above example, the-s option and the corresponding source address cannot be omitted. Even if we have already specified the number corresponding to the rule, when modifying a rule with the-R option, we must specify the original matching condition corresponding to the rule (if there are multiple matching conditions, we need to specify them).
SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.

80年代金球奖好剧。Jonathan Hart was a self-made millionaire--the CEO of Hart Industries, a global conglomerate. His gorgeous wife Jennifer was a freelance journalist. They were both amateur sleuths, and in every episode found themselves up to their eyeballs in murder, smuggling, theft and international espionage. They also managed to find time to snuggle together, as they loved each other very much. Max was their loyal, gravelly-voiced butler, cook & chauffeur, and Freeway their pet canine.
