Microsoft client connected to a Linux server causing a reboot?
 
A couple of weeks ago, we had an Oracle instantiation hang in a state of suspension we believe due to an improper Linux reboot. It is believed that the rebooting of the OS may have been caused by a simple “control-alt-delete” command issued from a Windows machine connected to the Linux server.

Could the commonly used “control-alt-delete” MicroSoft funtion cause a reboot when that client is connected to a Linux OS?

Is there any place I can go to find more documentation on this?

Thank you for any assistance you can provide.

I'm not sure if a connected Windows client could actually do this. In any case, on Red Hat family distros, to disable Ctrl + Alt + Delete reboots change the following in /etc/inittab:
Code:

# Trap CTRL-ALT-DELETE
ca::ctrlaltdel:/sbin/shutdown -t3 -r now

to:
Code:

# Trap CTRL-ALT-DELETE
#ca::ctrlaltdel:/sbin/shutdown -t3 -r now

(There are probably more elegant ways to accomplish this, but IIRC that should do it.)

Thank you!
 
Do you know where I might research this problem in more depth?
