least 9s is required to complete the first retry, and Connect-time is less than 9s). Therefore, the error 4 is reported. In a test set to connect-time=10s, the client initiates a connection for the first time, lasts 3s, does not succeed, retries for the first time, retries, does not succeed, arrives at connect-time time, and the client disconnects. Therefore, the error 110 is reported. In summary, assume that the value of/proc/sys/net/ipv4/tcp_syn_retries is n Then, when the TCP initiates the c

] because the floating-point value needs to save twice times the integer value, so JS will lose no chance to convert the floating-point value to an integer value, if the decimal point is not followed by any number or the floating-point value itself is an integer, this value will be saved as an integer value.[4.3.2.2] The highest precision for floating-point values is 17 decimal places[4.3.2.3] for a large or very small number, you can use the scientific notation E to represent the floating-point

I. Overview The full name of the RIP Protocol is the Routing Information Prot ocol. It is an internal gateway protocol (IGP) used to transmit route Information in an autonomous system (. The RIP Protocol is based on the Distance Vector (Distance Vector Algorithms). It uses the number of hops (metric) to measure the routing Distance to the target address. Ii. Restrictions of the Protocol1. The Protocol stipulates that the measurement of a valid route information cannot exceed 15, so that the Pro

When solving a problem, you usually have a situation where you are set to infinity. This time is usually set with 0x7fffffff, he is the computer 32-bit integer maximum number, the equivalent of Int_max. But in many cases this setting is not optimal and can lead to bugs because we sometimes want infinity + infinity = infinity
