Prohibition of Ping Command

Last updated: 2020-06-29 17:10:04

    Problem Description

    To protect TencentDB from DDoS attacks, TencentDB for MySQL prohibits the ping command from being used to check the network connectivity of a private network address by default.

    Note:

    You can use the ping command to check the network connectivity of a public network address.

    Solution

    We recommend troubleshooting and locating network connectivity problems quickly with the telnet command.

    • The command format is as follows:

      telnet private/public IP address private/public port
    • After the command is executed, network access status is as follows:

      • Normal network access
      • Exceptional network access

    Note:

    If there is still no network access after running the telnet command, you can easily troubleshoot private and public network connection problems with the connectivity check tool.
