[Linux] C Shell (csh) ping6用法: Test IPv6 connectivity

Overview

The ping6 command is used to test the reachability of a host on an Internet Protocol version 6 (IPv6) network. It sends Internet Control Message Protocol (ICMP) echo request packets to the specified address and waits for a response, helping to diagnose network connectivity issues.

Usage

The basic syntax of the ping6 command is as follows:

ping6 [options] [arguments]

Common Options

• -c <count>: Send a specified number of packets before stopping.
• -i <interval>: Set the interval between sending each packet (in seconds).
• -w <deadline>: Specify a time limit for sending packets (in seconds).
• -s <size>: Define the number of data bytes to be sent.

Common Examples

Here are some practical examples of using the ping6 command:

1. Ping a specific IPv6 address:

   ping6 2001:0db8:85a3:0000:0000:8a2e:0370:7334
   

2. Ping a host with a specific count of packets:

   ping6 -c 5 example.com
   

3. Ping a host with a custom interval between packets:

   ping6 -i 2 example.com
   

4. Ping a host with a specified packet size:

   ping6 -s 1280 example.com
   

5. Ping a host with a time limit:

   ping6 -w 10 example.com
   

Tips

• Use the -c option to limit the number of packets sent, which is useful for quick tests.
• Combine options to customize your ping tests, such as setting both the count and interval.
• If you are troubleshooting a network issue, consider using ping6 to check both local and remote IPv6 addresses to isolate the problem.
