KDUMPCTL(8) System Manager's Manual KDUMPCTL(8) NAME kdumpctl - control interface for kdump SYNOPSIS kdumpctl COMMAND DESCRIPTION kdumpctl is used to check or control the kdump service. In most cases, you should use systemctl to start / stop / enable kdump service instead. However, kdumpctl provides more details for debug and a helper to setup ssh key authentication. COMMANDS start Start the service. stop Stop the service. status Prints the current status of kdump service. It returns non-zero value if kdump is not operational. restart Is equal to start; stop propagate Helps to setup key authentication for ssh storage since it's impossible to use password authentication during kdump. showmem Prints the size of reserved memory for crash kernel in megabytes.
