Users Guide

• When Pass all keystrokes to server is enabled, <Ctrl+Alt+Del> is passed to the operating system on the
managed system.
• Magic SysRq keys are key combinations interpreted by the Linux Kernel. It is useful if the operating system on
the management station or the managed system freezes and you need to recover the system. You can enable
the magic SysRq keys on the Linux operating system using one of the following methods:
– Add an entry to /etc/sysctl.conf
– echo "1" > /proc/sys/kernel/sysrq
• When Pass all keystrokes to server is enabled, the magic SysRq keys are sent to the operating system on the
managed system. The key sequence behavior to reset the operating system, that is reboot without un-mounting
or sync, depends on whether the magic SysRq is enabled or disabled on the management station:
– If SysRq is enabled on the management station, then <Ctrl+Alt+SysRq+b> or <Alt+SysRq+b> resets the
management station irrespective of the system’s state.
– If SysRq is disabled on the management station, then the <Ctrl+Alt+SysRq+b> or <Alt+SysRq+b>keys
resets the operating system on the managed system.
– Other SysRq key combinations (example, <Alt+SysRq+k>, <Ctrl+Alt+SysRq+m>, and so on) are passed to
the managed system irrespective of the SysRq keys enabled or not on the management station.
