The invention discloses a remote debugging method. The method comprises the following steps: acquiring register data from a central control unit (CPU) through a serial platform environment control interface (PECI) bus; when it is determined that the register data is abnormal, sending a control instruction and the register data to a (Dash) network card through a serial bus (I2C), wherein the control instruction is used for indicating the (Dash) network card to send the register data to a remote debugging host, so that the remote debugging host performs remote debugging on an abnormal object corresponding to the register data in a workstation.
