CAUTION

Running this command exposes SSH server to public Piping Server. Someone who knows paths on the Piping Server can run any command on the machine.

Here are ways for using securely.

• Specify --password or -p in long or complex password.
• The paths should be long or complex.
• Use self-host Piping Server in private network
• Run this command on a machine which everyone may access to.
• Use Piping Server with some authentication methods such as basic auth or JWT.
