Prohibition of Ping Command

Last updated: 2019-11-20 16:47:29


Problem Description

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


You are recommended to troubleshoot and locate 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

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.
