Securing serial console redirection via serial-over-LAN (SOL)
An information handling system has the capability of securing serial console redirection via serial-over-LAN (SOL) by using a baseboard management controller (BMC) and a baseboard serial controller. The BMC may be coupled to the baseboard serial controller over a DCD and/or GPIO bus. De-assertion of the data carriage detect (DCD) signal from the BMC to the baseboard serial controller may cause the OS console to logout the user session. If the BMC does not support a DCD signal then a general purpose input-output (GPIO) signal from the BMC may be used instead. Most operating system (OS) consoles will logout a user session when a de-asserted DCD (or GPIO) signal is detected.
