Secure network system request support via a ping request

摘要

Methods and systems for secure network system request (sysrq) via Internet Control Message Protocol (ICMP) are described. A remote computing system sends a query over a network to a target computing system and determines whether the target computing system is non-responsive to the query. When the target computing system is non-responsive to the query, the remote computing system sends an ICMP request to the target computing system over the network. The ping request includes a command to be performed by the target computing system and a key to verify authorization to perform the command.

1. A method comprising:
establishing a secure channel with a target computing system over a network; sending, by a processing device at a remote computing system, a query over the established secure channel over the network to the target computing system; determining, by the processing device at the remote computing system, whether the target computing system is non-responsive to the query; and when the target computing system is non-responsive to the query, sending a ping request to the target computing system over an insecure channel over the network by the processing device at the remote computing system, wherein the ping request comprises a payload comprising a key and a command to debug the target computing system.
