Linux ping command details how to use the Linux ping command

When the ping command is executed, the ICMP transmission protocol is used to send the request response message. If the network function of the remote host is normal, the system returns the response message, so that the host operates normally.

Syntax

Ping [-dfnqrRv] [-c <number of completions>] [-I <interval seconds>] [-I <network interface>] [-l <preload>] [-p <Template style>]

[-S <packet size>] [-t <survival value>] [host name or IP address]

Parameter description:

• -D: Use the SO_DEBUG function of Socket.
• -C <number of completions> set the number of completed requests.
• -F limit detection.
• -I <interval seconds> specifies the interval between sending and receiving information.
• -I <network interface> use the specified network interface to send data packets.
• -L <preload> sets the data packet that is sent before the request information is sent.
• -N: only numbers are output.
• -P <Template style> sets the template style for filling data packets.
• -Q does not display the instruction execution process, except for the information at the beginning and end.
• -R ignores common Routing tables and directly sends data packets to the remote host.
• -R records the routing process.
• -S <packet size> sets the packet size.
• -T <survival value> sets the TTL value of the survival value.
• -V displays the instruction execution process in detail.

Instance

Checks whether it is connected to the host.
