# The magic SysRq key enables certain keyboard combinations to be # interpreted by the kernel to help with debugging. The kernel will respond # to these keys regardless of the current running applications. # # In general, the magic SysRq key is not needed for the average Ubuntu # system, and having it enabled by default can lead to security issues on # the console such as being able to dump memory or to kill arbitrary # processes including the running screen lock. # # Here is the list of possible values: # 0 - disable sysrq completely # 1 - enable all functions of sysrq # >1 - enable certain functions by adding up the following values: # 2 - enable control of console logging level # 4 - enable control of keyboard (SAK, unraw) # 8 - enable debugging dumps of processes etc. # 16 - enable sync command # 32 - enable remount read-only # 64 - enable signalling of processes (term, kill, oom-kill) # 128 - allow reboot/poweroff # 256 - allow nicing of all RT tasks # # For example, to enable both control of console logging level and # debugging dumps of processes: kernel.sysrq = 10 # kernel.sysrq = 176
