4. Timeouts and Resend Attempts: If the ping command does not receive a response within a specified timeout period, it will consider the packet lost and display a timeout error. The command will then attempt to resend the packet a certain number of times (usually three by default) before ...

If interval is not given, it sets interval to zero and outputs packets as fast as they come back or one hundred times per second, whichever is more. Only the super-user may use this option with zero interval. 洪泛ping。对于每个发送的ECHO_REQUEST,打印一个句点“.”,对于每个接收的ECHO_REPLY...
'-number_of_times--+---+-' +-TIMES-+ '-TIME--' Command parameters db_alias Specifies the database alias for the database on a DRDA® server that the ping is being sent to. This parameter, although mandatory, is not currently used. It is reserved for future use. Any valid databa...

One of the goals of this chapter is to see how the router provides this access. 路由器还连接到互联网-图中的云。 由于路由器连接到局域网和互联网,局域网上的所有机器也可以通过路由器访问互联网。 本章的目标之一是了解路由器如何提供这种访问。 Your initial point of view will be from a Linux-...
#记录ping的路由过程(IPv4 only) -s packetsize Specifies the number of data bytes to be sent. The default is 56, which translates into 64 ICMP data bytes when combined with the 8 bytes of ICMP header data. #指定每次ping发送的数据字节数,默认为“56字节”+“28字节”的ICMP头,一共是84字节 ...
