Java Based Virtual Console Session Running on Linux Operating System
The behavior mentioned for Windows operating system is
also applicable for Linux operating system with the following exceptions:
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.
